Description

A kind of torque wrench

Technical field

The utility model relates to spanner field, specifically relates to a kind of torque wrench.

Background technology

Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.

But it is narrower that existing torque wrench plays the scope of application, one pulls mouth can only corresponding a kind of nut.Convenient not when using, add the cost buying dissimilar torque wrench in addition.

Utility model content

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.

The structure of a kind of torque wrench of the present utility model as shown in Figure 1, Figure 2 and Figure 3, comprise handle 1 and the spanner 2 being arranged on handle 1 front end, described spanner 2 is provided with three not of uniform size first and pulls mouth 4, second and pull mouth 3 and the 3rd and pull mouth 5, described first pulls mouth 4 and second pulls the front end that mouth 3 is positioned at described spanner 2, described 3rd pulls the rear end that mouth 5 is positioned at described spanner 2, and described first pulls mouth 4 and second pulls mouth 3 and be connected and partly overlap.

In the present embodiment, also comprise regulating block 8, described regulating block 8 is arranged on described first and pulls mouth 4 and second and pull on mouth 3, and described regulating block 8 is provided with the 4th and pulls mouth 9 and the 5th and pull mouth 10.

In the present embodiment, the end of described handle 1 is provided with hanging hole 7.

Concrete, the described 3rd pulls mouth 5 is positioned at the dead astern that described first pulls mouth 4, and described second pulls mouth 3 is provided with removal hole 6.The setting of removal hole can facilitate regulating block 8 to pull mouth 4 and second from first to pull mouth 3 and depart from.

General, described first pulls mouth 4, second pulls mouth 3, the 3rd and pulls mouth 5, the 4th and pull mouth 9 and the 5th to pull the size of mouth 10 different.

In addition, described first pulls mouth 4 and second pulls mouth 3 and is connected in 8 shape, and described regulating block 6 is 8 shape.

The beneficial effects of the utility model: have and multiplely pull mouth, can be applicable to the nut of different size, compact overall structure is firm, easy to use.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
