Description

Retractable Multipurpose Wrench

technical field

The utility model relates to wrench technology, in particular to a retractable multipurpose wrench.

Background technique

A wrench is a commonly used installation and disassembly tool, which is mainly a hand tool that utilizes the principle of leverage to twist bolts, nuts, or other threads that hold bolts or nuts tightly. When in use, the bolt or nut can be twisted by applying an external force on the shank along the thread rotation direction. In the process of screwing bolts or nuts, whether it is labor-saving or whether the bolts and nuts can be tightened mainly depends on the torque given by the wrench, and the torque mainly depends on the length of the wrench handle. However, the length of the existing wrench handle is fixed, and there are many inconveniences during use. Moreover, the wrench head and the wrench handle are all connected in one-to-one correspondence, so that in the actual application process, multiple wrenches of different types and models need to be carried, which is not conducive to the convenience of carrying by the user.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1 and Figure 2, the embodiment of the present invention provides a retractable multi-purpose wrench, including,

Wrench head 1, which includes a wrench head body 11 and a fixture 12 fixedly connected to the wrench head body 11;

The trigger handle 2 includes a fixed handle 21 and a telescopic handle 22. One end of the fixed handle 21 is hollow and forms a telescopic cavity 211 arranged along the length direction of the fixed handle 21. One end of the telescopic handle 22 is matched and accommodated in the The other end of the telescoping chamber 211 is provided with a first fixing groove 221, and the fixing member 12 is matched and accommodated in the first fixing groove 221;

Wherein, the opening end of the fixed handle 21 close to the telescopic cavity 211 is provided with a first fixed hole 212 communicating with the telescopic cavity 211, and one end of the first fixed hole 212 is pressed against the outer wall of the telescopic handle 22 The first fixing bolt 3 is threaded; one end of the telescopic handle 22 is provided with a second fixing hole 222 communicating with the first fixing groove 221, and one end of the second fixing hole 222 is pressed against the fixing member 12 The second fixing bolt 4 of the outer wall is threaded.

Specifically, when the operator uses it, he can be equipped with a plurality of different models and different types of wrench heads 1 through a wrench handle 2, and different wrench heads 1 can be used for different bolts and nuts, especially when the operator needs to go out or When carrying a wrench, it is necessary to carry a plurality of wrenches of different models and different types, which is very inconvenient to carry. However, the wrench handle 2 and the wrench head 1 of this embodiment are detachably connected, and the wrench head 1 can be replaced during use. Wherein, the wrench handle 2 is provided with a fixed handle 21 and a telescopic handle 22. The length of the telescopic handle 22 can be set the same as the length of the telescopic cavity 211. During use, the length of the telescopic handle 22 located in the telescopic cavity 211 can be set according to needs, and through the first A fixing bolt 3 fixes the telescopic handle 22 in the fixing handle 21; correspondingly, the fixing member 12 is matched with the first fixing groove 221, and the fixing member 12 is fixed in the first fixing groove 221 by the second fixing bolt 4 .

As shown in Figure 1, in practical applications, a type of wrench head 1 may need to be used multiple times. In order to avoid the frequent replacement of the wrench head 1 and reduce its use efficiency, the fixed handle 21 in this embodiment is kept away from One end of the telescoping cavity 211 is provided with a second fixing groove 213 matched with the fixing member 12. Correspondingly, the fixing handle 21 is provided with a third fixing hole 214 communicating with the second fixing groove 213. The third fixing The hole 214 is internally threaded with a third fixing bolt 5 . When in use, there are generally at least two wrench heads 1 , and two of them can be selected to cooperate with the first fixing groove 221 and the second fixing groove 213 respectively according to needs. In addition, since open-ended and torx-shaped wrenches are the most commonly used two types of wrenches respectively, the wrench head body 11 of the wrench head 1 connected to the first fixing groove 221 and the second fixing groove 213 can be respectively set as an open-ended head and a torx-shaped wrench. Head, in order to correspond to the practical application.

Further, as shown in Figure 2, since the wrench head 1 is small in size, it is extremely inconvenient to carry, so the telescopic multipurpose wrench in this embodiment also includes a housing part 6, and the housing part 6 includes a The accommodating part body 61 for accommodating a plurality of wrench heads 1 and the fixing part 62 connected with the accommodating part body 61, when carrying, the fixing part 62 can be fixed to the second fixing part. slot 213, while a plurality of wrench heads 1 can be accommodated in the housing body 61 to increase the convenience of carrying.

In order to increase the stability of the wrench head 1 and prevent the wrench head 1 from shaking relative to the accommodating portion 6 when being carried, the inner wall of the accommodating portion body 61 is provided with a plurality of accommodating groove groups, and each of the accommodating grooves Each set includes two corresponding accommodating grooves 611 , and the two side walls of the wrench head 1 are fitted in the two corresponding accommodating grooves 611 .

Compared with the prior art, the utility model sets the wrench head and the wrench handle as a detachable connection, so that each wrench handle can be matched with a plurality of different models and different types of wrench heads, and only the wrench head needs to be replaced during use That is, the carrying amount of the wrench handle is reduced, and its portability is improved; moreover, the wrench handle is set as a fixed handle and a telescopic handle that can be stretched relative to the fixed handle, which can adjust the length of the wrench handle as required, and then adjust the twist Torque, which improves the convenience of its use.

The specific implementation manners of the utility model described above do not constitute a limitation to the protection scope of the utility model. Any other corresponding changes and deformations made according to the technical concept of the utility model shall be included in the protection scope of the claims of the utility model.
