Description

a labor-saving wrench

technical field

The present invention relates to the field of industrial machinery, in particular to a labor-saving wrench.

Background technique

As we all know, the improvement of a country's comprehensive national strength depends on the progress and development of its own industry, and machinery and equipment are particularly important as the pillar of industry. Therefore, the maintenance of mechanical equipment is also essential. Therefore, as a common tool for mechanical equipment maintenance, the wrench should attract enough attention and attention. At present, the wrenches on the market can be said to be in full bloom. For example, the document with the application number 201120483696.X discloses a labor-saving wrench, which includes a wrench head. The connection with the handle is set in the middle of the handle, which is simple in structure, easy to use, and can prevent the sleeve head from slipping, but the traditional wrench does not take into account that it takes a lot of effort to disassemble large machinery and requires the cooperation of multiple people, which is not conducive to improving work efficiency. And it does not consider whether the wrench itself is evenly stressed, which will easily cause a reduction in the service life of the wrench, and cannot meet the increasingly updated market demand.

Contents of the invention

The purpose of the present invention is to provide a labor-saving wrench to solve the above-mentioned multiple defects caused by the prior art.

A labor-saving wrench, comprising a connection dowel bar and a torx sleeve, the connection dowel bar is connected to the torx sleeve, and a rotating power-assisted wheel, the rotating power-assisted wheel is provided with six handles, and the handles are in an annular array Arranged uniformly, the connecting dowel rod is connected with the rotating booster wheel, and the plum blossom sleeve is connected with the connecting dowel rod.

Preferably, one end of the connecting dowel rod is embedded in connection with the rotating booster wheel, and the other end of the connecting dowel rod is also embedded in connection with the plum blossom sleeve.

Preferably, the interfaces connecting the dowel bar with the rotating power-assisted wheel and the plum blossom sleeve are regular hexagonal interfaces.

Preferably, the handle is provided with a texture.

The advantage of the present invention is that: the rotating booster wheel is provided with six handles, which can be operated by multiple people at the same time, which solves the problem of great effort when disassembling large machines. The handles are evenly arranged in a ring array, which can make the force more Uniformity, prolonging the service life of the wrench, one end of the connecting dowel bar is embedded with the rotating power wheel, and the other end of the connecting dowel bar is also embedded with the ring sleeve, so that it can be quickly used in various occasions. Assembled into the required wrench, the work efficiency is improved. The interface connecting the dowel rod, the rotating power wheel and the plum blossom sleeve is a regular hexagonal interface, which can better protect the disassembled parts. The handle is a textured handle, which can Play an effective anti-slip effect.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

As shown in Figure 1, a labor-saving wrench includes a rotating power-assisted wheel 1 connected to a dowel rod 2 and a torx sleeve 3, the rotating power-assisted wheel 1 is connected to one end of the dowel rod 2, and the torx sleeve 3 is connected to The other end of the dowel rod 2 is connected, and the rotating booster wheel 1 has six handles, which can be operated by multiple people at the same time, which solves the problem of great effort when disassembling large machinery. The handles are evenly arranged in a circular array, which can make the affected The force is more uniform and the service life of the wrench is extended.

It is worth noting that the connecting dowel 2 is embedded with the rotating power-assisted wheel 1 and the plum blossom sleeve 3, so that it can be quickly assembled into the required wrench in various occasions, which improves the work efficiency. The interface between the dowel bar 2 and the rotary power-assisted wheel 1 and the plum blossom sleeve 3 is a regular hexagonal interface, which can better protect the disassembled parts from being damaged. The handle is a textured handle, which can effectively prevent slipping.

In the present invention, if a wheel of a large excavator is disassembled, an appropriate wrench of the present invention is selected and operated by multiple people at the same time, the task can be quickly and labor-savingly completed and the overall service life of the wrench can be ensured.

Based on the above, there are six handles according to the rotating power-assisted wheel, which can be operated by multiple people at the same time, which solves the problem of great effort when disassembling large machinery. The handles are evenly arranged in a circular array, which can make the force more uniform and prolong the service life of the wrench.

It can be known from common technical knowledge that the present invention can be realized through other embodiments without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are embraced by the present invention.
