Description

Multifunctional ratchet wheel fastening wrench

Technical Field

The application relates to the technical field of maintenance tools, in particular to a multifunctional ratchet wheel fastening wrench.

Background

The round nut is used as a common fastening mechanical part, the hook end wrench is generally used for tightness operation, in the using process, the hook end wrench is unbalanced in stress, a fastening point is only provided with one groove, the hook end wrench has the problems of difficulty in clamping, easiness in hook release and the like, in the using process facing to the need of carrying out a large amount of disassembly and assembly, the hook end wrench is limited by a disassembly and assembly space, when the nut is rotated, the wrench needs to be taken down every time the nut is rotated by one angle, the nut is rotated again after being repositioned, the disassembly and assembly efficiency is extremely low, the round nut is often arranged at the tail end of a shaft, the bottom of equipment and other positions with smaller space, and if the operation space is narrow, the hook end wrench is more; the labor intensity for long-time use is very high, the working efficiency is very low, and certain inconvenience is brought to operators, so that the common hook wrench is obviously not suitable for certain specific working scenes, and the multifunctional ratchet wheel fastening wrench is provided for this reason

SUMMERY OF THE UTILITY MODEL

In view of the above, the present application proposes a multi-function ratchet fastening wrench to improve the above-mentioned problems.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a multi-functional ratchet fastening spanner, includes the handle, and the sleeve, the fixed ratchet switching-over device that has cup jointed in top of handle, telescopic top fixed mounting has the tooth head, telescopic bottom and the top fixed connection of handle.

Optionally, the sleeve is of a detachable structure, and different models of different numbers of tooth heads are fixedly mounted on the sleeve.

Optionally, the connection mode between the sleeve and the top end of the handle is a bolt clamping plum blossom sleeve.

Optionally, the sleeve is connected with the top end of the handle in a threaded sleeve manner.

Optionally, a ratchet assembly is arranged in the top end of the handle, and the ratchet assembly comprises a ratchet reversing device.

The application provides a pair of multi-functional ratchet fastening spanner possesses following beneficial effect:

1. this application sets up the different specifications into four to six teeth through the tooth head on the sleeve, thereby adapt to the use under the different situation, the practicality of device has been improved, and sleeve and tooth head are manufacturing for the integration, workable, intensity is high, life prolongs greatly, the change can be dismantled to sleeve and tooth head simultaneously, the change possesses the sleeve of different figure tooth heads, a fastening for different specification round nuts, or unload sleeve and tooth head and use as ordinary sleeve ratchet spanner, the usability of device has been improved greatly.

2. This application is through installing sleeve and tooth head on ordinary ratchet spanner for this use can realize the continuous gyration of round nut in limited space, and need not separate spanner and nut, has greatly improved work efficiency and operate convenience more, avoids needing many times to fix a position rotatory many times, makes work efficiency low, and not enough safety and stability, thereby has improved the practical application's of device reliability greatly.
