Description

A combined hexagon wrench

technical field

The utility model relates to a combined inner hexagonal wrench, which belongs to the field of connection, disassembly or clamping tools. the

Background technique

The existing L-shaped hexagon wrench set is a set of several wrenches to meet the hexagon socket bolts of various specifications, and there are many tool components, which are composed of a series of types of wrenches. The overall weight is large and inconvenient to carry. Moreover, it is easy to lose during carrying and using, and losing a wrench of an individual model will bring great inconvenience to the user. the

Utility model content

Aiming at the defects in the prior art, the purpose of this utility model is to provide a combined hexagon wrench, which has the advantages of being easy to carry and not easy to lose. It is suitable for fastening and dismounting of hexagon socket bolts in various occasions. the

In order to achieve the above object, the utility model adopts the following technical solutions:

A combined hexagonal wrench, comprising a handle, a first wrenching part, a second wrenching part, a third wrenching part, a spring and a latch part; the end of the handle has an inwardly protruding boss, the The upper ends of the first and second wrenching parts have hexagonal bosses protruding outwards, and the lower ends have hexagonal bosses protruding inwards. The upper ends of the third wrenching parts have outwards The protruding hexagonal boss; the first pulling part is nested on the handle through the hexagonal boss, the second pulling part is nested on the first pulling part through the hexagonal boss, and the second pulling part is nested on the handle through the hexagonal boss. The three wrenching parts are nested on the second wrenching part through the hexagonal boss; the handle, the first wrenching part and the second wrenching part are hollow structures, and one end of the spring is fixed in the upper cavity of the handle, The other end is fixed on the third wrenching part through the cavities of the first wrenching part and the second wrenching part, and is always in a compressed state; after the user selects the model of the wrenching part to be used, the redundant model wrenching part After being compressed into the cavity, insert the pin part (6) into the round pin hole to fix it.

Compared with the prior art, the utility model has the following obvious substantive features and progress:

The utility model combines various internal hexagonal wrenches of commonly used specifications, which does not need to be replaced during use, reduces the time wasted in searching for the wrench, and improves work efficiency. And not easy to lose. As long as the mechanical structure is not damaged, it can be used all the time. It does not require a lot of capital investment, is easy to manufacture, has high reliability and strong practicability.

Detailed ways

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail as follows:

As shown in Figures 1 to 6, a combined hexagon wrench includes a handle 1, a first wrenching part 2, a second wrenching part 3, a third wrenching part 4, a spring 5 and a latch part 6; The end of the handle 1 has a hexagonal boss protruding inward, the upper end of the first wrenching part 2 and the second wrenching part 3 has a hexagonal boss protruding outward, and the lower end has a hexagonal boss protruding inward. The protruding hexagonal boss, the upper end of the third pulling part 4 has a hexagonal boss protruding outward; the first pulling part 2 is nested on the handle 1 through the boss, the second The second wrenching part 3 is nested on the first wrenching part 2 through a hexagonal boss, and the third wrenching part 4 is nested on the second wrenching part 3 through a hexagonal boss; the handle 1, The first wrenching part 2 and the second wrenching part 3 are hexagonal hollow structures, and one end of the spring 5 is fixed in the upper cavity of the handle 1, and the other end passes through the first wrenching part 2 and the second wrenching part 3. The hexagonal cavity is fixed on the third wrenching part 4, and is always in a compressed state; after the user selects the model of the wrenching part to be used, after compressing the extra type of wrenching part into the cavity, the latch part (6 ) into the round pin hole for fixing. The method of using the combined hexagonal wrench is as follows:

Before use, you need to select the model of the wrenching part you need, press the end where the wrenching part is installed with your hand, so that the wrenching parts smaller than this type are compressed into the inner hexagonal cavity of the wrenching part of this model, and the latch part ( 6) Insert the round hole to fix the overlapping part of the wrenching part. At this time, the wrench at the bottom end of the wrench is put into the hexagonal hole of the bolt, and the wrench can be easily loosened or tightened by turning the wrench. In this embodiment, 4 types of wrench components are selected, but not limited to 4 types of wrench components, and the types and quantities of wrenches can be increased in actual products. the
