Abstract

The utility model discloses a multipurpose wrench, which comprises a body, a sleeve, a spring and a handle. One end of the body is a tool post wrench, the other end of the body is a chuck wrench, the spring is sleeved on the body, and the sleeve is sleeved on the outer portion of the spring. By means of combining the chuck wrench with the sleeve and adopting the spring as a medium, the multipurpose wrench realizes an automatic rebounding function when not used, not only saves consumables, but also is dual-purpose, and is simple in structure and convenient in use.

Description

A multipurpose wrench

technical field

The utility model relates to a multipurpose wrench, which relates to the technical field of metalworking. the

Background technique

As a student of engineering, it is inevitable to be exposed to various lathes in practice and future work, especially in the practical skills training and guidance of fitters and CNC lathes. In the production of today's society and the teaching and practice of various colleges and universities, some unreasonable or needing improvements are often encountered. The tools used often have to be changed, which is very inconvenient.

Analysis of problems existing in the use of lathe wrenches at this stage:

① Today's lathe wrenches have two sets of special purpose, which cannot be replaced, and are frequently replaced, which is troublesome;

②During apprentice turning (or student internship), there are often apprentices (or classmates) who use the chuck wrench to clamp the workpiece and then drive the car without taking it off. Some turning masters will also have this phenomenon, and the wrench will fly out and hurt people. Accidents pose serious safety hazards. the

Utility model content

The technical problem to be solved by the utility model is to provide a multi-purpose wrench for the deficiencies of the prior art, and adopt the following technical scheme:

The multi-purpose wrench includes a main body, a sleeve, a spring and a handle; wherein, one end of the main body is a tool holder wrench, the other end is a chuck wrench, the spring is placed on the main body, and the sleeve is placed outside the spring. the

Through the combination of the chuck wrench and the sleeve, the spring is used as the medium to achieve the function of automatically springing back when not in use. It not only saves consumables, but also achieves a wrench with two purposes, simple structure and convenient use. the

Detailed ways

Below in conjunction with specific embodiment, the utility model is described in detail. the

As shown in Figure 1 and Figure 2, it is a schematic diagram of the exploded structure of the utility model multi-purpose wrench, including a main body 10, a sleeve 20, a spring 30 and a handle 40; wherein one end of the main body 10 is a tool holder wrench 101 (Figure 3), The other end is a chuck wrench 102 ( FIG. 3 ), the spring 30 is sleeved on the main body 10 , and the sleeve 20 is sleeved outside the spring 30 . the

When in use, referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, install the main body 10, the spring 30, the sleeve 20, and the handle 40 in order: (a) put the spring 30 on the main body 10 with a chuck wrench 102 One end of the spring 30 is in full contact with the bottom end of the chuck wrench; (b) the sleeve 20 is placed outside the main body 10 equipped with the spring 30, and the other end of the spring 30 is placed on the top of the bore 201 in the sleeve 20; (c) Insert the handle 40 through the hole 201 on the sleeve 20 and the main body 10 and the through hole 103 of the main body (the handle is movable). When using the tool post wrench, replace the multi-purpose wrench with the tool post wrench end. When using a chuck wrench, replace the multi-function wrench with the chuck wrench end. the

When the multi-purpose wrench is used as a tool holder wrench, insert one end of the tool holder wrench 101 vertically into the tool holder nut. Before use, the handle 40 must be in full contact with the ring-shaped track (ie hole 201) on the sleeve 20 near the end of the tool holder wrench 101. Make sure that the tool holder wrench 101 is completely combined with the tool holder nut. the

When the multi-function wrench is used as a chuck wrench, one end of the chuck wrench 102 with the sleeve 20 will be in contact with the chuck mouth. Before use, the handle 40 must be close to the chuck wrench with the ring track (ie hole 201) on the sleeve 20 The semicircle of one end of 102 contacts completely, and chuck wrench 102 is pushed out sleeve 20, guarantees that chuck wrench 102 enters in the chuck mouth fully, and can use safely. After use, no force is applied to the handle, and the chuck wrench automatically shrinks in the sleeve 20 under the action of the spring 30 . the

According to actual operation experience, when using a multi-purpose wrench, one end of the handle can be used with a sleeve tube about 50 cm long, which not only saves labor but also achieves better results during operation. the

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present utility model. the
