Description

A multifunctional ratchet tightening wrench

technical field

The present application relates to the technical field of maintenance tools, and more particularly, to a multifunctional ratchet tightening wrench.

Background technique

As a commonly used fastening mechanical part, the round nut is generally tightened with a hook wrench. During use, the force of the hook wrench is unbalanced, and the fastening point has only one groove. The hook wrench is difficult to clamp, It is easy to remove the hook and other problems. In the process of using a large number of disassembly and assembly, the hook wrench is limited by the disassembly and assembly space. When rotating the nut, every time the nut is rotated, the wrench must be removed, and then repositioned. The efficiency of rotation and disassembly is extremely low. The round nut is often installed at the end of the shaft, the bottom of the equipment and other places with small space. If the operating space is small, it is more difficult to use a hook wrench; Low, which brings some inconvenience to the operator. Therefore, the ordinary hook wrench is obviously not suitable for some specific work scenarios. Therefore, a multi-functional ratchet tightening wrench is proposed.

Utility model content

In view of the above problems, the present application proposes a multifunctional ratchet tightening wrench to improve the above problems.

In order to achieve the above purpose, the present utility model is achieved through the following technical solutions: a multifunctional ratchet tightening wrench, comprising a handle and a sleeve, the top of the handle is fixedly sleeved with a ratchet reversing device, and the top of the sleeve is A tooth head is fixedly installed, and the bottom end of the sleeve is fixedly connected with the top end of the handle.

Optionally, the sleeve is a detachable structure, and different types of tooth heads with different numbers are fixedly installed on the sleeve.

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

Optionally, the connection between the sleeve and the top of the handle is threaded socket connection.

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

The multifunctional ratchet tightening wrench provided by the present application has the following beneficial effects:

1. In this application, the tooth heads on the sleeve are set to different specifications of four to six teeth, so as to adapt to the use in different situations, and improve the practicability of the device. Processing, high strength, greatly prolonging the service life, at the same time, the sleeve and the tooth head can be disassembled and replaced, and the sleeve with different number of tooth heads can be replaced for the tightening of round nuts of different specifications, or the sleeve and the tooth head can be removed as a common The use of a socket ratchet wrench greatly improves the usability of the device.

2. By installing the sleeve and the tooth head on the common ratchet wrench, the application can realize the continuous rotation of the round nut in a limited space without the need to separate the wrench from the nut, which greatly improves the work efficiency In addition, the operation is more convenient, avoiding the need for multiple positioning and multiple rotations, resulting in low work efficiency and insufficient safety and stability, thereby greatly improving the reliability of the device in practical applications.
