Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool set used in the maintenance of automobiles and the disassembly and assembly of machines.

[Conventional technology]

During this type of work, screws are often tightened or loosened together with bolts and nuts, and tightening or loosening operations are often performed by changing the grip of the tool or by moving the tool against the head of the bolt or nut. There is a demand for continuous work without the hassle of inserting and removing. For this reason, conventional socket trenches are equipped with a mounting part with a ratchet mechanism that removably fits and supports multiple types of socket bits for bolts, nuts, etc., and a ratchet that removably inserts and supports multiple types of driver bits. Separately prepare a screwdriver set with a recessed part for mounting with a mechanism, and switch to the wrench body or driver body depending on whether the object is a bolt/nut or screw. The main body was equipped with a socket bit or driver bit depending on the size and shape of the object. In this case, it is necessary to switch to the wrench body or screwdriver body depending on the object, and often the wrench body or driver body to be changed to is not at hand and has to be searched for. , it was troublesome and inconvenient.

[The problem that the idea aims to solve]

To solve this problem, it is possible to integrate the socket trench and driver set, but
In this case, the entire tool becomes too large, which is inconvenient and makes it difficult to use. Therefore, it may be possible to configure the socket bit mounting part of a socket trench, which mainly handles large diameter sockets, to be able to attach an adapter for mounting a driver bit, but in this case, there is a problem of increased costs due to an increase in the number of parts. In addition, the fact that the newly added adapter itself is a small part may lead to the problem of not being able to find it and having to go looking for it.

The present invention was developed in view of the above-mentioned circumstances, and allows bolts, nuts, etc. to be tightened or loosened using a single wrench body and without the need for larger tools or the addition of adapters. Another object of the present invention is to provide a tool set that enables tightening or loosening of screws, etc. using a driver bit.

[Means to solve the problem]

In order to achieve the above object, the tool set according to the present invention includes a plurality of types of socket bits for bolts, nuts, etc., a plurality of types of driver bits, and a square shaft for fitting and supporting the plurality of types of socket bits in a replaceable manner. It is composed of a wrench body provided with a socket bit mounting part shaped like a latch mechanism in combination, and a driver bit mounting recess that engages and supports the plurality of types of driver bits in a replaceable manner. , the socket bit mounting portion is formed concentrically at the angular axis thereof.

The functions and effects of the above characteristic configuration are as follows.

[Effect]

That is, since the rectangular shaft part forming the socket bit mounting part is used to form the driver bit mounting recess concentrically with this, by attaching and removing the socket bit to the outer periphery of the shaft of the socket bit mounting part, The socket bit is replaceable, and the socket bit mounting part is relatively long in the axial direction due to its rectangular shaft shape.The driver bit is formed by effectively utilizing the length in the axial direction. By attaching and detaching the driver bit to the mounting recess, it is possible to replace multiple types of driver bits, and tools such as socket bits and driver bits, which have very different mounting structures for wrenches, can be connected via a separate connection tool such as an adapter. It can be operated with the same ratchet mechanism without any trouble.

[Effect of idea]

A socket bit mounting part and a driver bit mounting recess can be directly provided on one wrench body without increasing the size of the tool, and therefore, it can be easily operated depending on whether the object to be operated is a bolt/nut or a screw. There is no need to switch to the wrench body or driver body, and there is no need to go looking for other tools or adapters. Tighten and loosen bolts, nuts, and screws using a single wrench body and its ratchet mechanism. It can be done easily.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, there are multiple types of socket bits 2 for bolts, nuts, etc.
, a square shaft-shaped socket bit mounting part 3 that removably fits and supports a plurality of types of driver bits 5 . . . and a plurality of types of socket bits 2 .
A tool set is constructed by combining this with a wrench body 1 provided via a ratchet mechanism 4. The socket bit mounting portion 3 is provided at one end of the wrench body 1 of this tool set.
At the shaft end of the square shaft-shaped portion, a driver bit mounting recess 6 is formed concentrically with the shaft to engage and support a plurality of types of driver bits 5 in a replaceable manner.

The ratchet mechanism 4 includes a shaft 7 having a socket bit mounting portion 3 formed at one end as described above.
is rotatably supported by the wrench body 1, and this shaft 7
A ratchet wheel 8 is fixed to the ratchet wheel 8, and a locking groove 8a for the ratchet wheel 8 is provided in a portion of the wrench body 1 corresponding to the ratchet wheel 8 only when the wrench body 1 is rotated in one direction.
A claw 9 that selectively engages with... to integrally rotate the wrench body 1 and the socket bit mounting part 3.
is provided in a state where it is elastically biased in the engagement direction.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
