Socket ratchet wrench

Abstract

The detachable sleeve ratcher spanner comprises the ratcher, driving part head, bar spanner body and the handle, sleeve frame containing the sleeve barrel inside the hollow spanner body, which is independent of the handle and being able to be integrated by assembly. The hollow handle forms a space to contain the sleeve rack with the cavity of the spanner body, the middle of the sleeve bracket bulging and both ends becoming smaller progressively. The handle can also be seal part of the sleeve bracket, with simple and labor saving operation, shape of the sleeve barrel allowing the even force bearing ability of the spanner to allow fast and steady connection of the handle and the spanner body.

Description

technical field [0001] The invention relates to a socket ratchet wrench, in particular to a socket ratchet wrench with a detachable and replaceable socket. Background technique [0002] The socket ratchet wrench is a hand tool that can control the direction of idling. Because it allows the operator to continuously turn the screw, bolt or nut without taking off the wrench, it is not only convenient for the user's operation, but also To overcome some space constraints, the socket ratchet wrench is an extremely widely used and important hand tool at present. [0003] Due to the different sizes of screws, nuts and nuts used in different occasions, the sleeves used to drive these screws, nuts and nuts also require different inner diameters to cooperate with them, so a tool has emerged. Inside the box, a socket ratchet wrench is placed, and a series of sockets with different inner diameters are also placed. These sockets can be detachably combined with the socket wrench, so as to...

AI Technical Summary

Problems solved by technology

Although the above-mentioned structure can greatly reduce the overall volume of the wrench, it still has the following disadvantages: first, the sealing part with a small contact area with the operator's hand needs to be removed every time the sleeve is taken and placed. , and then the sleeve holder can be pulled out to pick and place the required sleeves. The operation of pulling the sleeve holder is not very convenient. In addition, additional sealing parts are needed, which increases the production and processing procedures; secondly, the sleeve holder is small at one end and large at the other end. The tapered shape of the sleeve holder, when the operator needs to take and place the sleeve located at the smaller part of the sleeve holder, the user needs to pull out the entire sleeve holder to realize the above operation, and the operation of taking and placing the sleeve is not very easy. Fast; again, the larger part of the socket holder is placed at the end of the trigger body, which obviously makes the thickness of the material at the end of the trigger body thinner, and the end of the trigger body doubles as a handle, although the outer layer of the end of the trigger body is covered with a layer of rubber, plastic or glass. Foreskin, but when the wrench needs to work hard, the strength of the handle is not enough
