Abstract

PURPOSE: A flexible cable hand-tool is provided to make a combine unit between a tip end portion and a handle of a T-shaped handle, a crank handle, and an extension bar as a flexible cable. CONSTITUTION: A tip end of a cable(1) inserted to a cable-inserting hole(7) of a dedicated tip(6) is pressed through the entire circumference. The other end is inserted to a pipe. Both the ends of the cable are pressed to a cable holding portion and the center portion is to a strong press portion. A shaft tube(12) of a handle inserted by the other end of the cable is fixed through the entire circumference and width. A flexible spiral tube covering the cable forms a cap of the handle side to a synthetic resin cap. The space between the cap and the handle is formed as an injection liquid passage and sealing unused. A strong stress is not worked on each wire organizing the cable but dispersed to the entire cable. Thus, a constricting torque and rotational force are delivered from the handle to the dedicated tip. The cable is twisted if the cable is long. To prevent the cable from twisting and to maintain the bent state, the flexible spiral tube omits a cap of the handle side and forms a cap during synthetic resin injection forming. The passage formed by making the synthetic resin injection passage thin is easily broken as the flexible spiral tube is twisted. Therefore, a sealing effect proves the non-use.

Description

Hand Tool of Flexible Cable

The present invention relates to a flexible cable hand tool (hereinafter referred to as a cable hand tool) in which a connection portion between the tip and the handle is a flexible cable (hereinafter referred to as a cable) in various drivers, T-shaped handles, crank handles, extension bars, and the like. As regards the present invention, the cable hand tool has the advantage of being able to be used even in a narrow or curved space because the connection part is flexible and can transmit the tightening torque and the rotational force at the refracted angle.

The known cable hand tool is a cable holder that can insert various known bit holders as shown in Figs. 1, 2, and 3 of Utility Model Application No. 16324 (September 24, 1987). It has been used as a method of installing at the tip of the wire, or installing a rectangular convex part and inserting it into a box part of a known socket.

However, this method adds the length of the tip to the length of the tip, which makes it difficult to use in narrow spaces and interferes with conditions requiring rapid work. Specialized cable hand tools (hereinafter referred to as dedicated cable hand tools) that require direct connection of tweezers and sockets (hereinafter referred to as dedicated tips) are also required.

The method of crimping and fixing the bit holder at the end of the cable is to insert the cable into the cable insertion hole at the rear of the bit holder and press and fix one or several places. Press molding was used for injection molding, and T-type handles were used to press one or several places, but both ends and other ends were subjected to excessive tension and bending stress due to tightening torque and rotational force to the individual wires forming the cable. Because of the concentration, the damage of wire cutting or deformation progressed gradually, resulting in the breakage of cables.

In addition, a flexible spiral tube covering a cable has a hassle to squeeze a metal band in a spiral and penetrate the inner diameter of the cable, and has to be crimped with a stopper so that both ends thereof do not loosen.

In order to solve the above problems, the present invention provides a method of compressing a dedicated tip at the tip of a cable in constructing a dedicated cable hand tool, and inserting a cable into a pipe or a shaft at the other end of the cable gripping portion of the pipe or a shaft. It is formed at both ends, and the center is a strong press molding part for transferring the tightening torque, and the handle side stopper of the bellows at both ends is molded into a synthetic stopper when the handle is injected with synthetic resin, and at the same time, it also serves as a mark of unused seal. The dedicated tip is magnetized (着 磁) or inserted into a magnet to be used.

The known cable (1) is made by repeating left and right twists of several strands of wires (3), (4), and (5) on a core wire (2) made of a wire. , The end of the cable (1) cut to an arbitrary length is inserted into the cable insertion hole (7) at the rear of the dedicated tip (6) and crimped and fixed over the entire circumference, and the other end is a screwdriver handle (9) A pipe 13 is fitted to the handle fixing part 8, and in the case of the known T-shaped handle 10 and the crank handle 11, the pipe 13 is inserted into the shaft tube 12.

2, the handle fixing part 8 is fixed at both ends of the pipe 13 to the cable gripping part 14, and the center part to the crimping part 15, and then into the driver handle 9 which is injection molded. The shaft tube 12 is crimped over the entire circumference and width. Dedicated tip (6) is a known socket, bit, tip, bit holder, etc. As shown in Figure 3, reference numeral 16 is a hexagonal socket (Hexagon Wrench), 17 is a Torx Wrench (Torx Wrench) , (18) is the Torx Socket, (19) is the Hexagon Wrench, (20) is the Star Wrench, (21) is Bits (22) are bit holders.

As shown in Fig. 4, the bellows 23 covering the cable 1 is fitted with a stopper 24 at the tip and the other end is molded with a synthetic stopper 27, while at the same time the passage and unused seal 28 of the synthetic resin injection solution is molded. Be sure to

Referring to the embodiment of FIG. 5 to which the present invention is applied, 29 is a socket cable driver, 30 is a socket bellows cable driver, 31 is a socket cable T-shaped handle, and 32 is a socket bellow. Cable crank handle. (33) is a socket bellows cable hex bit connector and fits into the bit holder (22).

In the present invention, since the dedicated tip is directly connected to the front end of the cable, there is no hassle to combine the tool rules and can be easily used even in a narrow work space. The tip of the cable is fitted to the dedicated tip and pressed over the entire circumference, and the other end is a driver. In the case of T-type and crank-type handle, it is inserted into the shaft tube and pressed over the circumference of the cylindrical surface to compress the crimp area. By increasing the width, it is possible to strongly transmit the tightening torque and rotational force from the handle to the dedicated tip by dispersing the entire cable without strong stress applied to each wire constituting the cable.

In addition, if the cable is long, the cable may be twisted and twisted.In order to prevent this and to maintain the bending state, the screw handle of the java, which covers the cable, omits the handle side plug, and forms a plug during the injection molding of the resin, At the same time, the passage portion formed by thinning the passage of the synthetic resin injection liquid is easily broken when twisting the bellows, so there is a sealing effect to prove unused.

Known tip can be used to magnetize or insert a known magnet.
