The present utility model is described below with reference to the accompanying drawings without distinguishing between orientation gyro transmitters.

As shown in fig. 1 to 4, the present utility model relates to a gyro emitter without distinguishing orientation, which comprises a first clamping arm 1 and a second clamping arm 2 with connecting ends hinged to each other, wherein opposite sides of movable ends of the first clamping arm 1 and the second clamping arm 2 form a clamping part 6 for clamping a gyro, the mutual hinging is not necessarily elastic, i.e. torsion springs are not required to be arranged at the hinging part to realize elastic hinging, but other modes are adopted to realize that the first clamping arm 1 and the second clamping arm 2 can rotate relatively around the hinging part to enable the clamping part 6 to be opened.

The utility model is characterized in that: the first clamping arm 1 is internally provided with the stay cord driver 4, the second clamping arm 2 is internally provided with the accelerating gear set 3, generally, the installation refers to non-replaceable or not-easy-to-detach installation, the installation refers to non-replaceable or non-detachable connection, namely, the stretching driver 4 and the accelerating gear set 3 are locked in the respective clamping arms through screws or fixedly connected in the respective clamping arms through other modes such as welding and cementing, and the shells of the first clamping arm 1 and the second clamping arm 2 are also mutually locked, so that not all players can easily detach and replace the same by bare hands. The design can separate the stay cord driver 4 from the accelerating gear set 3, so that the volume of the first clamping arm 1 and the volume of the second clamping arm 2 can be designed to be almost the same, the degree of freedom of the design of the top emitter is greatly improved, and the emitter cannot become bulked even if the volume of the second clamping arm 2 is designed to be larger than the volume of the first clamping arm 1; the existing clip type emitter has the disadvantages that the volume of the first clamping arm 1 is relatively large, if the second clamping arm 2 is designed to be larger than the first clamping arm 1, the whole clip type emitter becomes very bulkier, the appearance is affected, and the carrying is inconvenient and the occupied area is also caused. Therefore, the gyro emitter can be designed to be more attractive and cool, has smaller volume and is more convenient to carry and can attract the favor of players.

The pull rope driver 4 is provided with a first transmission gear 41, and the first transmission gear 41 extends out of the opposite side of the first clamping arm 1; the accelerating gear set 3 comprises a second transmission gear 31 and an output gear 32, the output gear 32 extends into the clamping part 6, and the output gear 32 is positioned at the middle position of the second clamping arm 2 in the thickness direction, as shown in fig. 4; the thickness of the second clamping arm 2 refers to the distance from the top surface to the bottom surface of the second clamping arm 2, as identified by H height in fig. 4; by intermediate position, it is meant that the distance from the intermediate position of the output gear 32 to the top surface of the second clamp arm 2 is the same as the distance from the intermediate position of the output gear 32 to the bottom surface of the second clamp arm 2, as shown by L1 and L2 in fig. 4. Just because the stay cord driver 4 and the acceleration gear set 3 are separately arranged, the output gear can be easily designed to be positioned at the middle position of the thickness direction of the second clamping arm 2, and the effect of the design is that: the top surface of the top emitter is upward or the bottom surface of the top emitter is upward, and the clamping part 6 can clamp the top and accelerate the top, namely, a player does not need to distinguish which surface of the top emitter is the top surface when using the top emitter, so that the top emitter is convenient to operate, the 0 foundation can be used, and the top emitter is suitable for being used by players with smaller ages; moreover, the gyro emitter is applicable to right hand holding and left hand holding, and has strong applicability. As shown in fig. 1, when the top launcher is held by a left hand, the top surface of the top launcher faces upward, and the top is held by the upper portion of the holding portion 6; when the transmitter is held by the right hand, as shown in fig. 2, the bottom surface of the transmitter faces upward at this time, and the lower part of the holding part 6 (the lower part at this time is above) holds the top. The utility model realizes that the gyro emitter of the same acceleration gear set 3 can rotate the gyro clockwise or anticlockwise by the indifferent design of the front and the back, such as the gyro emitter shown in fig. 12, which is in a left hand and top surface up state, and the gyro is rotated anticlockwise, but if the gyro is still left hand and the bottom surface is up, the gyro is rotated clockwise at this time, or is changed to be right hand and the top surface is still up, and the gyro is rotated clockwise at this time.

As shown in fig. 3, in some embodiments, a protrusion 14 is provided on an opposite side of the first arm 1 (i.e., a side facing the second arm 2), and a first opening 13 is provided in the protrusion 14 toward the second arm 2, and a first transmission gear 41 is located inside the protrusion 14 and has a portion protruding from the first opening 13 to the outside of the first arm 1. That is, the portion of the pull cord actuator 4 is located within the protrusion 14, and the remaining portion of the pull cord actuator 4 occupies a relatively small area of the first clip arm 1, so that the first clip arm 1 of this embodiment can be designed to be smaller than the existing clip type emitters. Correspondingly, the opposite side of the second clamping arm 2 is provided with a concave position 24 corresponding to the convex block 14, and the shape of the concave position 24 is consistent with that of the convex block 14, so that when the first clamping arm 1 and the second clamping arm 2 are relatively folded, the convex block 14 can be embedded into the concave position 24, and therefore the convex block 14 does not occupy the external space of the whole gyro emitter, and the volume of the whole gyro emitter after folding is smaller than that of the existing clip emitter. Correspondingly, the second opening 23 is formed on the wall surface of the concave portion 24 facing the first clamping arm 1, and the second transmission gear 31 is located in the second clamping arm 2 and aligned with the second opening 23, so that when the movable ends of the first clamping arm 1 and the second clamping arm 2 are close to each other, the protruding block 14 is embedded in the concave portion 24, as shown in fig. 5, and at this time, the protruding portion of the first transmission gear 41 protrudes into the second opening 23 to be meshed with the second transmission gear 31.

To facilitate the installation connection of the pull cord driver 4 to the first clip arm 1 during production, in some embodiments, as shown in fig. 6, the first clip arm 1 includes a first upper housing 11 and a first lower housing 12 that are fastened to each other, and a cavity is formed in the first upper housing 11 and the first lower housing 12, and the pull cord driver 4 is installed in the cavity and locked in the cavity by a screw. The pulling end of the pulling cord driver 4 extends from the cavity to the outside of the first arm 1, and the extending direction of the pulling cord end may be the direction opposite to the direction of the clamping portion 6 as shown in fig. 6, or may be the front end in the longitudinal direction of the first arm 1; the first upper shell 11 and the first lower shell 12 are locked by screws after being buckled, so that the stay cord driver 4 is locked in the first clamping arm 1, and other manners such as gluing can be adopted for locking besides screw locking.

The rope pulling driver 4 of the utility model is characterized in that the accelerating gear set 3 is arranged separately from the rope pulling driver, so that compared with the structure composition of an automatic winder of the existing clip type gyro, the rope pulling driver 4 has simpler structure. As shown in fig. 7, the pull cord driver includes a driving case 45, a cord 46, a reel 42, an input gear 43, a first transmission gear 41 and a spring plate 44, wherein the reel 42 and the input gear 43 are coaxially connected to realize synchronous rotation, the spring plate 44 is connected to the input gear 43, the first transmission gear 41 is always meshed with the input gear 43, the driving case 45 includes a driving case 451 and a driving cover 452, the input gear 43 and the first transmission gear 41 are mounted in the driving case 451, the driving cover 452 covers the opening end of the driving case 451 to realize that the two gears are accommodated in the driving case 45, the reel 42 is mounted on the upper end surface of the driving case 45, i.e. on the outer end surface of the driving case 451, a hole is opened in the driving case 451, the square boss 431 is convexly arranged towards the direction of the hole, the end surface of the reel 42 towards the direction of the hole is provided with a square boss 431 (not shown in the drawing), and the square boss 431 and the square boss hole 24 are cooperatively and then screwed to realize synchronous rotation of the input gear 43 by the reel 42. The spring plate 44 is embedded in the lower end face of the driving box 45, namely, the driving cover 452, a circular concave 453 is arranged in the direction of the driving cover 452 towards the input gear 43, a hole is formed in the middle of the circular concave 453, the spring plate 44 is embedded in the circular concave 453, a cylinder (not shown in the figure) is arranged in the direction of the input gear 43 towards the hole, the inner end of the spring plate 44 is connected with the cylinder, and the outer end of the spring plate 44 is clamped and fixed with the driving cover 452, so that when the input gear 43 rotates, the spring plate 44 stores energy or releases energy. The fixed end of the cord 46 of this embodiment is locked to the reel 42 and integrally wound around the reel 42, and the pull-cord end of the cord 46 extends out of the first clip arm 1, and is connected to a pull-ring 47. When the rope 46 is pulled by the hand-held pull ring 47, the rope 46 is pulled out from the reel 42, the reel 42 is pulled to rotate, the input gear 43 is driven to synchronously rotate, and the rotation of the input gear 43 drives the inner end of the spring plate 44 to rotate, so that the spring plate 44 stores energy; when the tension on the cord 46 is removed, the spring plate 44 releases energy, driving the input gear 43 and reel 42 to reverse rotation, thereby retracting the cord 46 and rewinding it on the reel 42.

Also for easy installation of the accelerating gear set 3, in some embodiments, as shown in fig. 8, the second clamping arm 2 includes a second upper housing 21 and a second lower housing 22, the accelerating gear set 3 is installed between the second upper housing 21 and the second lower housing 22, the second upper housing 21 and the second lower housing 22 are both provided with notches 26 on the abutting edges of the clamping portion 6, the two notches 26 form a through opening together after the second upper housing 21 and the second lower housing 22 are buckled, and the output gear 32 extends into the clamping portion 6 from the through opening.

The accelerating gear set 3 of the present utility model may be directly mounted in the second arm 2, that is, as shown in fig. 8, the accelerating gear set 3 of this embodiment includes only two gears, that is, the second transmission gear 31 and the output gear 32, and correspondingly, holes for mounting the axles of the two gears are provided in the second arm 2. Specifically, in order to realize that repeated pulling of the cord 46 can realize continuous acceleration of the gyro, in this embodiment, the second transmission gear 31 is designed as a gear with a clutch function, that is, a hole in the second clamping arm 2 for mounting a wheel shaft of the second transmission gear 31 is designed as an arc-shaped slot 353, and the wheel shaft can slide in the length range of the arc-shaped slot 353 after being placed in the arc-shaped slot 353, that is, the second transmission gear 31 has the clutch function; the hole for installing the wheel shaft of the output gear 32 is a circular shaft hole 354, and the wheel shaft of the output gear 32 is arranged in the shaft hole 354 to realize autorotation. The clutch function is realized as follows: when the cord 46 of the pull cord driver 4 is pulled out by the player, the second transmission gear 31 is deviated to one end of the arc-shaped groove 353 and meshed with the output gear 32, so that the power of the pull cord driver 4 can be transmitted to the top to realize the rotation of the top, as shown in fig. 12; when the player releases the cord 46, the cord 46 is retracted, and at the moment, the first transmission gear 41 is reversed to drive the second transmission gear 31 to deviate to the other end of the arc-shaped groove 353, so that the second transmission gear 31 is disengaged from the output gear 32, namely, the second transmission gear 31 idles and does not drive the output gear 32 to reversely rotate, so that the original rotation direction of the spinning top is not influenced, and the spinning top continuously rotates at the clamping part 6 according to the original rotation direction, as shown in fig. 13; until the player pulls the cord 46 again, the second transmission gear 31 is meshed with the output gear 32 again, and the top is continuously accelerated in the original rotation direction.

In addition, the accelerating gear set 3 of the utility model has the function of accelerating the gyro, namely, at least one of the second transmission gear 31 and the output gear 32 is designed as a double gear, and the small diameter gear of the double gear is meshed with the gear receiving the power, and the large diameter gear is meshed with the gear transmitting the power. As shown in fig. 8, in this embodiment, the second transmission gear 31 is designed as a duplex gear, in which the small diameter gear of the second transmission gear 31 is meshed with the first transmission gear 41, and the large diameter gear is meshed with the output gear 32, so that the second transmission gear 31 can also play a role in accelerating, so as to accelerate the output gear 32, and further accelerate the gyro. Although the output gear 32 of this embodiment is not designed as a double gear, it actually has an acceleration function because the diameter of the output gear 32 is larger than that of the gyro gear on the gyro, and since the large diameter power is transmitted to the small diameter and the small diameter can be rotated more than once, the output gear 32 can have an acceleration function as long as it has a diameter larger than that of the gyro gear.

The accelerating gear set 3 of the utility model can also comprise a gear box 35, namely, the gears are packaged in the gear box 35, and then the gear box 35 is fixedly connected into the second clamping arm 2, so that the installation process is simpler and more convenient, and a plurality of gears are not required to be manually installed in the second clamping arm 2. In addition, the gears of the accelerating gear set 3 may be more than the second transmission gear 31 and the output gear 32, and new gears may be added to change the steering direction of the output gear 32 or to improve the accelerating transmission effect. The proper accelerating gear set 3 can be selected for installation in the production process according to market demands.

In the first embodiment shown in fig. 9, the accelerating gear set 3 of this embodiment includes a gear box 35, a second transmission gear 31 and an output gear 32, where the second transmission gear 31 is a duplex gear, that is, includes a large diameter gear and a small diameter gear stacked one above the other, where the small diameter gear is meshed with the first transmission gear 41, and the large diameter gear is meshed with the output gear 32, so that the second transmission gear 31 can also play a role in accelerating to achieve acceleration of the output gear 32.

The concave position on the gear box 35 for placing the wheel axle of the output gear 32 is designed as a shaft hole 354, and the wheel axle of the output gear 32 is placed in the shaft hole 354 to realize autorotation; the concave position of the gear box 35 for placing the wheel axle of the second transmission gear 31 is designed as an arc-shaped groove 353, so that the wheel axle can slide in the length range of the arc-shaped groove 353 after being placed in the arc-shaped groove 353, thereby realizing the clutch function of the second transmission gear 31.

When the player holds the top launcher with his left hand and pulls the cord 46 of the cord driver 4 with his right hand, the acceleration gear set 3 drives the top in the clamping portion 6 to rotate counterclockwise, and the specific power transmission direction is shown in fig. 12.

As shown in fig. 10, in the second embodiment, the accelerating gear set 3 of the present embodiment includes a gear box 35, a second transmission gear 31, an intermediate gear 33 and an output gear 32, where the intermediate gear 33 is a double gear, that is, includes a large diameter gear and a small diameter gear stacked one above the other, where the small diameter gear is meshed with the second transmission gear 31, and the large diameter gear is always meshed with the output gear 32, so that the intermediate gear 33 can perform an accelerating function to accelerate the output gear 32.

When the player holds the top launcher with his left hand and pulls the cord 46 of the cord drive 4 with his right hand, the acceleration gear set 3 drives the top in the grip 6 to rotate clockwise. The accelerating gear set 3 of this embodiment may be a single-stage accelerating gear set 3 or a multi-stage accelerating gear set 3 if it is distinguished by the accelerating level, specifically, depending on the size of the second transmission gear 31, when the size of the second transmission gear 31 is the same as the size of the first transmission gear 41, the accelerating gear set 3 accelerates only through the intermediate gear 33, so that it is the single-stage accelerating gear set 3; when the second transmission gear 31 is smaller in size than the first transmission gear 41, the second transmission gear 31 also has an acceleration function, and the intermediate gear 33 accelerates again, so that the acceleration gear set 3 in this case is a multistage acceleration gear set 3.

As shown in fig. 11, in the third embodiment, the accelerating gear set 3 includes a gear box 35, a second transmission gear 31, an intermediate gear 33, a second accelerating gear 34 and an output gear 32, that is, four gears in total, where the second transmission gear 31 and the second accelerating gear 34 are duplex gears, the intermediate gear 33 and the output gear 32 are single-link gears, a small diameter gear of the second transmission gear 31 is meshed with the first transmission gear 41, a large diameter gear of the second transmission gear 31 is meshed with the intermediate gear 33, the intermediate gear 33 is meshed with a small diameter gear of the second accelerating gear 34, and a large diameter gear of the second accelerating gear 34 is meshed with the output gear 32. In this embodiment, at least the second transfer gear 31 and the second acceleration gear 34 perform acceleration, that is, the second transfer gear 31 and the second acceleration gear 34 are acceleration gears, and thus the acceleration gear set 3 is a multi-stage acceleration gear set 3.

The concave positions on the gear box 35 for the placement of the wheel axle of the second transmission gear 31, the wheel axle of the intermediate gear 33 and the wheel axle of the output gear 32 are designed as shaft holes 354, so that the wheel axles of the three gears are placed in the shaft holes 354 to realize autorotation; the concave position on the gear box 35 for placing the axle of the second accelerating gear 34 is designed as an arc groove 353, so that the axle of the second accelerating gear 34 can slide in the length range of the arc groove 353 after being placed in the arc groove 353, that is, the second accelerating gear 34 has a clutch function, when the rope 46 of the rope driver 4 is pulled out by a player, the second accelerating gear 34 is deviated to one end (the right lower end position in the drawing) of the arc groove 353 and meshed with the output gear 32, and the power of the rope driver 4 can be transmitted to a top to realize the top rotation; when the player releases the cord 46, the cord 46 is retracted, and the second accelerating gear 34 is shifted to the other end (upper left end position in the drawing) of the arc-shaped groove 353, so that the second accelerating gear 34 is disengaged from the output gear 32, that is, the second transmission gear 31, the intermediate gear 33 and the second accelerating gear 34 idle together, and the output gear 32 is not driven to rotate in the opposite direction, so that the original rotation direction of the spinning top is not affected, the spinning top continues to rotate in the clamping part 6 in the original rotation direction until the player pulls the cord 46 again, so that the second accelerating gear 34 is engaged with the output gear 32 again, and the spinning top continues to accelerate in the original rotation direction.

In order to facilitate the operation and use of the first clamping arm 1 and the second clamping arm 2, when the hand is released, the first clamping arm 1 and the second clamping arm 2 automatically rotate around the hinged position to open the clamping part 6, an elastic piece can be arranged at the hinged position, for example, a compression spring 52 is arranged on the opposite sides of the two clamping arms near the hinged position, and the compression spring 52 can spring the second clamping arm 2 away from the first clamping arm 1 when the hand is released, similar to the existing elastic pliers; for example, a resilient iron sheet is provided on the opposite side of the first arm 1/second arm 2 near the hinge, and is inclined toward the other arm in the initial state, i.e., the other arm is pushed away, and when the two arms are pinched by the hand, the resilient iron sheet is elastically deformed to be integrally fitted on the opposite side of the first arm 1/second arm 2. In addition, as shown in fig. 14 and 15, the connection ends of the first clamping arm 1 and the second clamping arm 2 are hinged by a connection mode of the rotating shaft 15 and the rotating hole 25, wherein the first clamping arm 1 is provided with an elastic ejector rod 5 near the connection end, the elastic ejector rod 5 is installed in the first clamping arm 1, the elastic ejector rod 5 comprises an ejector rod 51 and a spring 52, a mounting groove 16 is arranged in the first clamping arm 1, the ejector rod 7 is movably installed in the mounting groove 16, one end of the spring 52 is propped against the rear end face of the ejector rod 7, and the other end is propped against the bottom of the mounting groove 16. When the player does not apply pinching force to the first clamping arm 1 and the second clamping arm 2, the ejector rod 51 ejects towards the direction of the second clamping arm 2 under the action of the elastic force of the spring 52, so as to push against the opposite side of the second clamping arm 2, so that the movable end of the second clamping arm 2 rotates around the rotating shaft 15 and is far away from the movable end of the first clamping arm 1, namely the clamping part 6 is opened, and the clamping of the top is released; when the movable ends of the first clamping arm 1 and the second clamping arm 2 are close, the opposite sides of the second clamping arm 2 can press the ejector rod 51, the ejector rod 51 can retract into the mounting groove 16 of the first clamping arm 1, and the ejector rod 51 can compress the spring 52 to store energy of the spring 52.

The following describes the usage of the gyro emitter of the present utility model in detail.

Firstly, clamping a top: the player holds the gyro launcher by left/right hand, the movable ends of the first clamping arm 1 and the second clamping arm 2 are kept in an open state, and then the gyro is placed at the clamping part 6 of one clamping arm by the other hand; then, the first clamping arm 1 and the second clamping arm 2 are clamped by holding the top emitter by hand, the two clamping arms are mutually closed, the top is clamped by the clamping part 6, the gear on the top is meshed with the output gear 32, the elastic jack is retracted into the first clamping arm 1, and the first transmission gear 41 extends into the second clamping arm 2 to be meshed with the second transmission gear 31.

The gyro is accelerated as follows: the state of holding the two clamping arms is kept, the fingers of the other hand hook the holes of the pull ring 47, then the pull ring 47 is pulled, the pull ring 47 drives the thread rope 46 to be pulled out, so as to drive the reel 42 and the input gear 43 to rotate, meanwhile, the spring plate 44 stores energy, the input gear 43 rotates to drive the first transmission gear 41 to rotate, the first transmission gear 41 drives the second transmission gear 31 to rotate, a gear serving as a clutch gear in the accelerating gear set 3 is switched to a meshing state, namely, the output gear 32 is finally driven to rotate, and the output gear 32 drives the gyro gear to rotate, so that the gyro is realized; when the wire rope 46 is pulled to the end or pulled out for a certain distance, the hand holding the pull ring 47 removes the pulling force, at this moment, the wire rope 46 is quickly retracted and rewound on the reel 42 under the action of the energy released by the spring plate 44, at this moment, the reel 42, the input gear 43 and the first transmission gear 41 are all rotated reversely, the clutch gear in the accelerating gear set 3 is rotated reversely, and meanwhile, the state is switched to a leaving state, namely, the reverse rotation of the clutch gear does not drive the output gear 32 to rotate, and at this moment, the gyroscope continues to rotate under the action of the original rotation inertia force; then the thread 46 is pulled again to realize the second rotation driving of the top; the rotation acceleration of the gyroscope can be realized by repeating the steps.

Finally, a top is launched: when the player feels that the gyro is sufficiently accelerated, the hand holding the pull ring 47 releases the pull ring 47, and then the hand holding the gyro emitter moves to the desktop or the ground, so that the top of the gyro approaches the desktop or the ground; then the holding force is removed, namely the hand is slightly loosened, at the moment, the elastic ejector rod 5 ejects, the ejector rod 51 pushes the second clamping arm 2 away from the first clamping arm 1, so that the clamping part 6 is opened, and the top loses the clamping force and automatically falls to the desktop or the ground to rotate.
