Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a socket wrench used for assembling or dismounting bolts and nuts.

[0002]

[Prior Art]

 As disclosed in Japanese Utility Model Laid-Open No. 63-27264, a conventional socket wrench is a ratchet that rotates integrally with the handle at one end of the handle when it rotates in the tightening direction and slips when the handle rotates in the loosening direction. It is equipped with a car and has a handle with a square drive shaft protruding from the center of rotation of this ratchet car, and a hexagonal or dodecagonal socket of various sizes with square holes that fit into the square drive shaft of this handle. It consists of a combination.

[0003]

[Problems to be solved by the device]

 In the conventional socket wrench described above, the handle and the socket are stored separately from each other, so it is necessary to take out a socket of a required size from the storage part away from the handle and mount it on the handle. It may be lost.

Further, the handle is only attached to the square drive shaft to rotate the socket, and does not have the function of rotating the bolts and nuts by the handle itself, and one end of the socket is the square drive of the handle. Since it has a square hole that fits into the shaft, the hexagonal or dodecagonal polygonal hole that fits into the bolt / nut is one size polygon hole in one socket, and various sizes are available. Bolt. In order to support nuts, a large number of socket sets of various sizes are required, and the tool price is high.

An object of the present invention is to provide a socket wrench that solves the above conventional problems.

[0006]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is to provide a handle in which a polygonal first hole and a second hole having the same size are formed at least at one end, and what is included in the first hole and the second hole. It comprises a polygonal outer peripheral portion which can be fitted therein and a polygonal hole having different sizes in both sides in the axial direction, and the socket is housed in one of the first hole and the second hole. ..

[0007]

[Action]

 With the above structure, the first hole provided in the handle is used to tighten and loosen the bolt and nut adapted to the polygonal hole, and the second hole is used as a storage hole for the socket. Also, the one socket that is stored has two sizes of different sizes and is used by fitting it into the first hole of the handle, and at least one end of the handle can be used to tighten and loosen bolt nuts of three sizes. Is possible.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 is a handle (handle). A hexagonal or dodecagonal first hole 2 and a second hole 3 of the same size are formed at one end of the handle 1. The first hole 2 may be provided in a rotating cylinder 4 that rotates integrally with the handle 1 in one direction and slides in the other direction by an unillustrated ratchet wheel and forward / reverse rotation switching claws 5 in an integrated manner.

Reference numeral 6 is a socket. As shown in FIGS. 3A to 3C, the socket 6 has a polygonal outer peripheral portion 7 that can be fitted into both the first hole 2 and the second hole 3 of the handle 1. A large size hexagonal or dodecagonal large polygonal hole 8 and a small size hexagonal or dodecagonal small polygonal hole 9 are formed on both sides in the axial direction. Further, a ball 10 pressed by a spring is provided on the polygonal outer peripheral portion 7, and a recess (not shown) for engaging the ball 10 is provided on the first hole 2 and the second hole 3. There is.

In the above description of the configuration, the first hole 2 and the second hole 3 are provided at one end of the handle 1, and the structure is such that the socket 6 that can be fitted into these holes 2 and 3 is combined. As shown in FIG. 1, similarly, the other end of the handle 1 is also provided with a third hole 2a and a fourth hole 3a having different sizes from the first hole 2 and the second hole 3, respectively. You may combine the socket 6a which has the polygonal outer peripheral part 7a which can be fitted in the 4th hole 3a.

Since the present invention has the above-described structure, the socket 6 is normally housed in the second hole 3 as shown in the left side of FIG. 1 and FIG. In this case, the first hole 2 is used to tighten and loosen the bolt and nut adapted to the polygonal hole.

When tightening and loosening bolts and nuts smaller in size than the first hole 2, by fitting and mounting the socket 6 stored in the second hole 3 into the first hole 2, Bolts and nuts of two different sizes, large polygonal hole 8 and small polygonal hole 9, can be tightened and loosened.

In the socket 6 fitted and mounted in the second hole 3 and the first hole 2, the ball 10 is engaged with a recess (not shown) to prevent the ball 10 from falling off.

As shown in FIG. 1, a third hole 2a and a fourth hole 3a are similarly provided at the other end of the handle 1, and a polygonal outer periphery that can be fitted into the third hole 2a and the fourth hole 3a. When the socket 6a having the portion 7a is combined, a single handle can be used to tighten and loosen bolts and nuts of six sizes.

[0015]

[Effect of the device]

 As described above, according to the present invention, the polygonal first hole and the second hole having the same size are formed in the end portion of the handle (handle), and the handle can be fitted in either the first hole or the second hole. A polygonal outer peripheral portion and polygonal holes of different sizes are provided on both sides in the axial direction, and the socket is housed in either the first hole or the second hole. Therefore, the handle itself is also a bolt.・ Has a function of tightening and loosening nuts, and the socket is compatible with two sizes of bolts and nuts, and one handle can be used to tighten and loosen 3 to 6 types of bolts and nuts of various sizes. It is possible to reduce the cost.

Further, since the socket is always stored in the handle, there is an advantage that the socket can be prevented from being lost and the socket can be quickly replaced when the size of the bolt / nut is changed.
