Description

  The present invention includes, for example, a rock drill, a concrete breaker, a lifting machine, a nailing machine, a rivet driving machine, a pile driving machine, a ground leveling machine, a compactor, a rammer, a tamper, a compactor, an asphalt or a concrete leveling machine, a so-called jet chisel, etc. It is related with the auxiliary | assistant tool for vibration tools which mount | wear and use the vibration tool comprised for such things.

  Conventionally, various vibration tools as described above have been proposed (see Patent Documents 1 to 4). In addition, a configuration provided with a vibration isolator has already been disclosed in order to prevent the impact generated by the reciprocating motion of the piston loaded in the vibration tool from being transmitted to the operator (see Patent Document 5). For example, the configuration disclosed in Patent Document 5 includes a buffer chamber in which a rear end portion of an air hammer body is filled with a buffer liquid, a buffer cylinder into which a buffer sliding body is inserted, and a buffer chamber and a buffer cylinder. A buffering mechanism is provided which includes a communication hole formed in a buffering cylinder that communicates with the interior of the buffering cylinder.

  Various configurations in which a gripping portion of a vibration tool is provided with a vibration absorbing function are also disclosed (see Patent Documents 6 to 8). For example, the configuration disclosed in Patent Document 8 includes a grip portion that can be moved at least in a direction substantially corresponding to the vibration direction of the work tool, and an elastic body that is interposed between the grip portion and the handle body portion. And.

Japanese Patent No. 4340081 Japanese Patent No. 3825802 Japanese Patent No. 2746712 JP-A-8-197458 JP-A-9-11156 JP 2007-168070 A JP 2009-297887 A JP 2011-705 A

  However, the configurations of Patent Documents 1 to 4 have a configuration in which a tip such as a chisel that has obtained kinetic energy by the impact of a hammer vibrates strongly with respect to the tool body. Also vibrates strongly. Therefore, in order to prevent the tool from bouncing or the tip tool from being displaced from the hit object such as the object to be crushed, or to effectively transmit the force caused by the vibration of the tip tool to the hit object, The tool body must always be pressed against strong vibrations, and the strong vibrations are transmitted to the worker, causing serious problems such as white rot on the worker's body due to prolonged use. The problem is that there is a high possibility that

  Although the configuration of Patent Document 5 has the possibility of solving the above-described problem, in order to fill the tool body with a sufficient amount of buffering liquid that provides a sufficient buffering effect, the buffer chamber has As a result, the size of the tool increases, and the tool itself increases in size as a whole, and the weight increases. Consequently, there is a problem that it is very difficult for an operator to handle. In addition, since the buffer liquid must be filled in the tool without leaking, there is a problem that the internal structure becomes highly accurate and complicated, and the manufacturing cost increases. Furthermore, since the number of parts of the entire tool increases, disassembly and cleaning becomes extremely troublesome, and there is a problem that maintenance cannot be performed easily. Therefore, the configuration disclosed in Patent Document 5 for these reasons is extremely impractical and is not currently on the market.

  In addition, the configurations disclosed in Patent Documents 6 to 8 described above are vibrations that are not damped when the vibration absorbing function is not sufficiently exhibited or the hand that operates the switch unit for controlling the driving state of the vibrating tool is operated. There was a problem that was transmitted directly. In addition, if an elastic body having a high vibration absorbing effect is selected, it is difficult to transmit a strong striking force to the striking object via the vibration tool, which causes a so-called torcross. For example, in the configuration disclosed in Patent Document 8, the vibration generated from the vibrating tool is still directly transmitted to the hand operating the switch unit provided in the tool body, which ultimately places a heavy burden on the operator. There is a problem.

  Therefore, the present invention can be easily applied to an existing vibration tool that is inferior in vibration absorption, can dramatically reduce vibration and noise transmitted to an operator while attached to the vibration tool, and has an impact force during work. It is an object of the present invention to provide an auxiliary tool for a vibration tool that can be finely adjusted, and has a simple and lightweight structure and can be manufactured at low cost.

  The present invention relates to a vibration tool auxiliary tool that is used by being attached to a vibration tool having a front end tool at a front end, and the auxiliary tool main body is attached to the vibration tool and an operator holds the attachment tool. A gripping member; and a vibration absorbing portion connected to the gripping member and the mounting portion. Further, the outer peripheral surface of the vibration absorbing portion of the auxiliary tool body is in the front-rear direction and perpendicular to the front-rear direction. A pair of wall portions disposed in the left-right direction and the three directions of the front-rear direction and the up-down direction orthogonal to the left-right direction are provided, and the gripping member is a wall between the wall portions. A guide portion is provided that slidably holds at least a part of the gripping member so as to be slidable along the facing direction of the portion, and one of the wall portions and the gripping member are provided. A first elastic body that elastically deforms along the facing direction of the wall A second elastic body that is inserted and elastically deformed along the facing direction of the wall portion is interposed between the other wall portion and the gripping member. It is.

  Here, when the vibration tool is driven, for example, an impact generated when the hammer in the vibration tool collides with the tip tool, or vibration due to the inertia of the hammer that reciprocates is transmitted to the auxiliary tool body. However, the gripping member gripped by the operator is held between the pair of front and rear wall portions by the elastic body while being held by the guide portion so as to be slidable in the front-rear direction. It is pressed down so as to maintain a balanced position of the urging force generated by the reaction force due to the elastic force with the body. For this reason, the vibration from the vibrating tool is suitably absorbed by the elastic body, and it is difficult for large vibrations to be transmitted to the operator holding the gripping member. In addition, it is possible to reduce noise generated by the vibration tool at the vibration absorbing portion of the vibration tool auxiliary tool. In addition, a pair of wall part provided with the elastic body may be provided about all three directions, may be provided about two directions, and may be provided about any one direction.

  The pair of wall portions are provided along the front-rear direction, and the gripping member is slidable along the front-rear direction between the wall portions, and the front side wall portion and the gripping member among the wall portions A first elastic body that is elastically deformed along the front-rear direction is interposed between the second elastic body that is elastically deformed along the front-rear direction between the rear side wall portion and the gripping member. The inserted configuration is proposed.

  Here, normally, the gripping member has a fixed position where the elastic force of the front elastic body and the rear elastic body is balanced, but in a working state in which the tip of the vibration tool is in contact with the strike target, It is also possible to work by pushing the gripping member further forward from the fixed position against the elastic force of the front elastic body at an appropriate timing toward the hit target. When the gripping member is pressed further forward than the fixed position in this way, the front elastic body approaches the elastic limit, and the elastic force of the front elastic body is attenuated, thereby efficiently applying the pressing force by the operator to the hit target. It becomes possible to add. Therefore, for example, when there is a part where the film thickness is partially thick during the peeling operation of the coating film using a vibration tool, the impact force is instantaneously reduced by pressing the gripping member momentarily toward the part. It is amplified, and it becomes possible to give a striking force strongly and intensively to the part via the tip of the vibration tool. As described above, the present invention can temporarily convert the vibration absorption effect into the amplification of the striking force and apply the pressing force toward the striking target, and can perform flexible work according to the work environment. it can.

  The gripping member is movably provided with an operation member that changes the position between an operation position and a non-operation position. The operation member further includes an interlocking member that operates in conjunction with the operation member. The interlocking member is in contact with a switch portion formed on the vibration tool, and when the operation member is positioned at the operation position, the interlocking member is in accordance with the operation of the interlocking member interlocked with the operation member. When the switch part is turned on and the vibration tool is in a driving state, and the operation member is positioned at the non-operation position, the switch part is turned off in accordance with the operation of the interlocking member linked to the operation member. The vibration tool may be in a non-driven state.

  With this configuration, it is possible to control the drive state of the vibration tool with its hand while gripping the gripping member, and work even when mounted on a general-purpose product that has a switch section on the body of the vibration tool. It can be avoided that a large vibration is transmitted to a person.

  In the configuration described so far, the pair of wall portions are disposed along the front-rear direction, and the first elastic body is configured by a front coil spring that is elastically contracted in the front-rear direction, When the second elastic body is composed of a rear coil spring in a state of being elastically contracted in the front-rear direction, and the gripping member is pressed toward the hitting object in a state where the tip of the vibration tool is in contact with the hitting target The front coil spring preferably biases the gripping member rearward, and the rear coil spring biases the gripping member forward.

  Here, the front coil spring has a function of absorbing an impact generated when the hammer in the vibration tool collides with the tip tool and an inertia of the hammer that reciprocates. On the other hand, since the gripping member is constantly urged backward with respect to the vibrating tool by the reaction force of the front coil spring during work, the pressing force of the tip tool against the strike target is reduced and the overall strike force is reduced. It is conceivable that the gripping member becomes weak or the gripping member jumps between the front wall portion and the rear wall portion, and a stable striking force cannot be obtained. Therefore, in order to solve this problem, the rear coil spring has a function of pressing the gripping member forward appropriately against the vibration tool. That is, in any of the driven state, the non-driven state, and the state in which the tip tool is pressed against the impact target in the non-driven state, the gripping member moves the front coil spring against the vibration tool. And the rear coil spring are pressed so as to maintain a balanced position of the urging force, so that the tip tool can be appropriately pressed against the strike target. Thus, by gripping the gripping member and performing the work, not only the vibration of the vibration tool is favorably absorbed, but also a stable striking force is obtained, and the workability is remarkably improved.

  Moreover, it is good also as a structure which at least any one wall part is free to move along a facing direction with respect to the said auxiliary tool main body, and a separation distance can be changed about this pair of wall part.

  In this way, by making it possible to change the separation distance between the pair of wall portions, the magnitude of the elastic energy of both elastic bodies can be changed in a state of being disposed between the wall portions without exchanging the elastic bodies themselves. Is possible. Therefore, for example, the separation distance may be decreased to increase the urging force of both elastic bodies and suppress the torque cross of the vibration tool. For example, the separation distance may be increased to decrease the urging force of both elastic bodies. A high vibration absorbing effect may be obtained.

  A striking force adjustment method is also proposed in which the striking force is adjusted by changing the urging force of the rear coil spring against the gripping member. For example, when the urging force of the rear coil spring against the gripping member is increased, the striking force is increased. On the other hand, when the urging force is decreased, the striking force is decreased. With this configuration, it is possible to finely adjust the striking force necessary for the work at that time while preventing large vibrations from being transmitted to the worker.

  The auxiliary tool for a vibration tool of the present invention can be easily applied to an existing vibration tool having an inferior vibration absorption effect, dramatically reducing vibration or noise transmitted to an operator while attached to the vibration tool, and The impact force can be finely adjusted during the operation, and the structure is simple and lightweight, so that it can be manufactured at low cost.

It is explanatory drawing which shows the use condition of the auxiliary tool for vibration tools. It is explanatory drawing which shows another use condition. It is a schematic diagram which shows a modification.

  Hereinafter, the embodiment which materialized the auxiliary tool for vibration tools of the present invention (henceforth suitably called auxiliary tool) is described in detail. Here, the auxiliary tool is used by being attached to a vibration tool provided with a tip tool at the front end, and for convenience, the direction in which the tip tool (for example, a chisel) of the vibration tool is inserted is defined as the front. The direction opposite to this will be referred to as the rear, and this direction will also be used in the description of the auxiliary tool. However, this does not exclude that the vibration tool 100 is used vertically upward or vertically downward with the auxiliary tool 1 attached. In addition, this invention is not limited to the Example shown below, A design change is possible suitably.

  As shown in FIGS. 1 to 4, the auxiliary tool body 2 in the auxiliary tool 1 includes an attachment portion 3 attached to the vibration tool 100 and a gripping member 4 having a substantially U-shape that is gripped by an operator. doing. The auxiliary tool body 2 also includes a vibration absorbing portion 5 connected to the attachment portion 3 and the gripping member 4. A substantially horizontal gripping portion 14 is formed on the top of the gripping member 4.

  The mounting portion 3 is formed with a through-hole 31 having a circular cross section that opens in the front-rear direction. An inner diameter of the through hole 31 is determined in accordance with an outer shape of a body portion of the vibration tool 100 described later, and the vibration tool 100 is inserted into the through hole 31 so that the attachment portion 3 and the vibration tool 100 They are fixed to each other by known fixing means so as not to rattle.

  The vibration absorbing portion 5 of the auxiliary tool body 2 is formed with a pair of front and rear front side wall portions 21 and rear side wall portions 22 erected on the outer peripheral surface so as to be separated from each other. Further, between the front side wall portion 21 and the rear side wall portion 22, a guide support shaft (guide portion) 23 having a circular cross section with the axial direction as the front-rear direction is passed.

  Further, the guide support shaft 23 is formed in one end portion 41 of the gripping member 4 and is inserted into a through hole 42 opened in the front-rear direction, and the gripping member 4 is bushed 43 with respect to the guide support shaft 23. It is hold | maintained so that sliding back and forth is possible. At the same time, a front coil spring 51 as a first elastic body oriented in the front-rear direction is provided around the guide support shaft 23 and between the front side wall 21 and the one end 41 of the gripping member 4. It is inserted so as to be elastically deformable in the direction. A rear coil spring 52 as a second elastic body oriented in the front-rear direction is interposed between the rear side wall part 22 and the one end 41 of the gripping member 4 so as to be elastically deformable in the front-rear direction. ing. Note that the front coil spring 51 and the rear coil spring 52 are preferably configured to function as so-called compression springs, but may be configured to function as tension springs.

  As shown in FIG. 2, a pair of wall portions 25, 25 are provided on the left and right sides of the gripping member 4 in the auxiliary tool body 2 with the gripping member 4 as the center. And between the one wall portion 25 and the one end portion 41 of the gripping member 4 and between the other wall portion 25 and the one end portion 41 of the gripping member 4, an auxiliary that can be elastically deformed in the left-right direction. Auxiliary coil springs 53 and 53 are inserted as elastic bodies. The auxiliary coil springs 53 and 53 are preferably configured to function as so-called compression springs, but may be configured to function as tension springs.

  Further, as shown in FIG. 1, a proximal end portion of a rod-like operation member 45 is rotatably attached via a rotating portion 46 in the vicinity of the holding portion 14 of the holding member 4. In other words, the distal end portion of the operation member 45 is attached in a state of being pushed out toward the center of the grip portion 14. Further, a hollow guide groove 50 is formed in the holding member 4 in the vertical direction from the vicinity of the proximal end portion of the operation member 45 to the other end portion 44 of the holding member 4. A hook-like interlocking member 48 is inserted into the guide groove 50 and arranged to be movable up and down. An annular drop-off prevention member 49 is attached to the upper end portion of the interlocking member 48, and the drop-off prevention member 49 can be locked to the upper groove end 47a of the guide groove 50.

  As shown in FIG. 3, the auxiliary tool 1 described above is used by being attached to the body portion of the vibration tool 100. Here, the vibration tool 100 has a tip tool 101 composed of a chisel or the like attached to the front end, and a hammer loaded therein reciprocates in the front-rear direction to repeatedly collide with the base end of the tip tool 101. By doing so, a predetermined striking force is applied to the tip tool 101. The vibration tool 100 may be an electric type or a compressed air type, and a driving state and a non-driving state are controlled by an operation of an elongated plate-like switch unit 102 arranged at the rear part. When an operator presses the hand against the switch unit 102 and depresses the switch unit 102 toward the main body, the power source is activated and the hammer starts to reciprocate. When the hand is released from the switch 102, the switch unit 102 rotates in a direction away from the main body according to the urging force applied to the rotating unit (not shown) of the switch unit 102 and returns to the normal position to cut off the power. When the hammer stops, it becomes a non-driven state.

  In the above configuration, the body portion of the vibration tool 100 is inserted into the through hole 31 of the attachment portion 3 of the auxiliary tool 1 and the attachment portion 3 and the vibration tool 100 are connected to each other by a known fixing means (not shown). They are fixed to each other without rattling. For example, it may be configured to screw together. Further, the body portion of the vibration tool 100 is formed with a small-diameter portion sandwiched between a pair of large-diameter portions formed at the front and rear, and can be divided at the boundary between the large-diameter portion and the small-diameter portion, and is separated Then, after the small-diameter portion is inserted into the through hole 31 of the attachment portion 3, the vibration tool 100 and the auxiliary tool 1 may be assembled by being interconnected. Further, when the auxiliary tool 1 is mounted on the vibration tool 100, the lower end of the interlocking member 48 comes into contact with the switch portion 102 formed on the vibration tool 100. Since the switch 102 is urged to rotate upward (in a direction away from the main body), the interlocking member 48 is lifted upward in the mounted state and abuts against the proximal end portion of the operation member 45, so that Are connected to each other. Accordingly, the distal end portion of the operation member 45 is pressed downward, that is, the state where the distal end portion of the operation member 45 is biased to a state separated from the grip portion 14. When the distal end portion of the operation member 45 is rotated upward and the position of the operation member 45 is changed to the operation position, the interlocking member 48 is lowered in conjunction therewith, and the switch portion 102 is pressed downward. Then, the switch unit 102 is turned on and the vibration tool 100 is driven. On the other hand, when the distal end portion of the operation member 45 rotates downward to change the position to the non-operation position, the interlocking member 48 rises according to the urging force in the switch portion 102, and the switch portion 102 is turned off. The vibration tool 100 is in a non-driven state.

  As described above, when the mounting portion 3 is firmly fixed to the vibration tool 100 without rattling, the large vibration generated by the vibration tool 100 is also transmitted to the auxiliary tool 1, and a vibration absorption effect can be obtained at a glance. However, since the auxiliary tool 1 is separately provided with a vibration absorbing portion 5 to be described later, the attachment portion 3 can be firmly fixed to the vibration tool 100 without any problem and is fixed without loosening. Excellent work safety.

  Then, the operator may hold the holding portion 14 of the holding member 4 and operate the vibration tool 100 while simultaneously operating the operation member 45 with a little finger or the like. Here, normally, the gripping member 4 has a fixed position where the elastic forces (biasing forces) of the front coil spring 51 and the rear coil spring 52 are balanced. As shown in FIG. In a working state in which 101 is in contact with the hit target W, the gripping member 4 can be instantaneously pressed forward from a fixed position toward the hit target W at an appropriate timing. When the gripping member 4 is momentarily pressed forward in this way, the front coil spring 51 momentarily contracts in the front-rear direction to near the limit, temporarily losing the rearward biasing force, and applies a pressing force to the hit target W It becomes possible. Therefore, for example, when there is a partially thick part of the coating film to be peeled, it is possible to repeatedly apply a striking force mainly on the part by repeatedly pressing the gripping member 4 forward toward the thick part. It becomes. Therefore, the auxiliary tool 1 has not only a function of protecting the worker from vibration generated by the vibration tool 100 but also a function of giving a strong striking force to the striking target W at an appropriate timing according to the work situation. There is an advantage that it is easy to use, and the working efficiency can be dramatically increased.

  Further, the vibration absorbing portion 5 of the auxiliary tool 1 includes not only the front coil spring 51 and the rear coil spring 52 that exhibit a vibration absorbing effect in the front-rear direction, but also auxiliary coil springs 53 and 53, and the grip portion 4 Is loosely fitted to the guide support shaft 23 via the bush 43, so that the vibration absorbing portion 5 is moved to the left and right by the gap of play of the through hole 42 of the grip portion 4 with respect to the guide support shaft 23. The vibration absorption effect with respect to the direction can be exhibited. In addition, you may make it hold | maintain the said guide support shaft 23 so that it can move to the left-right direction with respect to the auxiliary tool main body 2. FIG.

  When the gripping member 4 is pressed toward the striking target W while the tip tool 101 of the vibration tool 100 is in contact with the striking target W, the front coil spring 51 is elastically contracted to cause the gripping member 4 to move. The rear coil spring 52 is biased rearward and the gripping member 4 is biased forward. With this configuration, the gripping member 4 is constantly urged rearward by the reaction force of the front coil spring 51 during work, so that the pressing force of the tip tool 101 against the striking target W is reduced as a whole. It is conceivable that the striking force becomes weak or the gripping member 4 jumps between the front side wall portion 21 and the rear side wall portion 22 and a stable striking force cannot be obtained. The side coil spring 52 has a function of appropriately pressing the gripping member 4 forward. That is, in any case of the driven state, the non-driven state of the vibration tool 100, and the state where the tip tool 101 is pressed against the strike target W in the non-drive state, the gripping member 4 is placed on the vibration tool 100. On the other hand, the front coil spring 51 and the rear coil spring 52 are pressed so as to maintain a balanced position of the urging force, so that the tip tool 101 is appropriately pressed against the striking target W and the gripping is performed. The splash of the member 4 can be prevented. As a result, a stable striking force can be obtained.

  The auxiliary tool 1 having the above configuration has a simple structure, a small number of parts, a compact overall structure, and a reduction in weight. Therefore, when the vibration tool 100 itself has a structure excellent in vibration absorption performance, the cost inevitably increases, while the auxiliary tool 1 is attached to the existing vibration tool 100, while the cost is kept low. It is possible to provide a work environment that takes into consideration the health of the worker.

A modification of the vibration absorber 5 will be described with reference to FIG.
As shown in FIG. 5, a configuration in which a reference fixing wall portion 27 is fixedly provided on the outer peripheral surface of the vibration absorbing portion 5 in the auxiliary tool body 2 and in front of the rear side wall portion 22 is proposed. The reference fixing wall portion 27 is provided with a screw hole 28 along the front-rear direction, and an adjustment screw 61 is screwed into the screw hole 28 so that the front end faces the rear side wall portion 22. Further, the front side wall portion 21 made of a plate material is fixed to the tip of the adjustment screw 61, and the front side wall portion 21 moves back and forth as the adjustment screw 61 moves back and forth with respect to the reference fixing wall portion 27. .

  With this configuration, the separation distance between the front side wall portion 21 and the rear side wall portion 22 can be changed, and the magnitude of the elastic energy of the front side coil spring 51 and the rear side coil spring 52 can be changed without replacing the coil spring itself. It becomes possible to do. Therefore, for example, the separation distance between the front side wall portion 21 and the rear side wall portion 22 may be reduced to increase the elastic energy of each of the coil springs 51 and 52 to ensure an appropriate striking force. It is also possible to set conditions so that an absorption effect can be obtained even for strong vibrations by increasing the separation distance between the rear wall 21 and the rear side wall 22 to reduce the elastic energy of the coil springs 51 and 52. The above configuration is a configuration in which the front side wall portion 21 is provided on the adjustment screw 61. Instead, the front side wall portion 21 is always fixed and the reference fixing wall portion is provided behind the front side wall portion 21. The rear side wall 22 may be provided at the tip of the adjustment screw 61 so that the rear side wall 22 can be moved back and forth. In addition, the configuration in which the separation distance between the front side wall portion 21 and the rear side wall portion 22 can be adjusted as appropriate is not limited to such a configuration. For example, the wall members constituting the wall portions 21 and 22 are connected to the auxiliary members. The structure which comprises the front side wall part 21 and the rear side wall part 22 by desired separation distance by selecting and attaching / detaching one of the some fixing holes drilled in the tool main body 2 may be sufficient.

  Further, by appropriately changing the spring constant of the rear coil spring 52, the striking force applied to the striking target W may be adjusted while ensuring the optimum vibration absorbing effect. For example, when it is desired to increase the striking force, the spring constant of the rear coil spring 52 is changed to increase the forward biasing force on the gripping member 4. Then, the gripping member 4 is pressed further forward with respect to the vibration tool 100, and accordingly, the gripping member 4 is prevented from jumping, and the striking force is increased while the posture of the vibration tool 100 remains stable. . On the other hand, when it is desired to reduce the striking force, the spring constant of the rear coil spring 52 is changed to weaken the forward biasing force against the gripping member 4. Then, the force with which the gripping member 4 is pressed forward against the vibration tool 100 is reduced, and accordingly, the striking force is reduced while the gripping member 4 is prevented from jumping and the posture of the vibration tool 100 is maintained stable. .

  In the present invention, the design can be changed as appropriate in addition to the above embodiments. For example, the auxiliary tool 1 is preferably made of a metal material, but may be made of a plastic material. Further, the overall shape of the vibration tool 100 to which the auxiliary tool 1 is attached is not limited to the straight shape described above, and may be a handle shape having an approximately L shape in side view. The design is appropriately changed according to the shape of the vibration tool 100. In addition, the structure of the attachment portion 3 in the auxiliary tool 1 is not limited to the above configuration, and a so-called vise structure is adopted so that the vibration tool can be attached to different types of vibration tools, and the body portion of the vibration tool is provided. It may be a sandwich type mounting structure that sandwiches appropriately.

  In addition, the surface of the grip portion 14 of the grip member 4 may be made of an elastic material such as rubber so that it can be easily gripped. Moreover, you may make it fill a required part with the objective of noise reduction for a fiber material. As the fiber material, felt (needle punched nonwoven fabric) made of polyester fiber can be employed.

  The gripping member 4 may be provided with a vibration absorbing portion that can obtain a vibration absorbing effect by an elastic body that elastically deforms in the vertical direction. The tip tool 101 of the vibration tool 100 is not limited to a configuration that can move only in the front-rear direction, but may move in the left-right direction, may move in the up-down direction, or may rotate in a predetermined direction. May be. Further, the guide support shaft 23 as the guide portion may have another configuration, and the guide portion may be a guide groove or the like.
