Socket ratchet wrench

Abstract

The invention relates to a socket ratchet wrench with a detachable and replaceable socket, which has a ratchet wheel and a head of a driving part, a rod-shaped wrench body and a handle part, wherein the wrench body is hollow and contains a socket frame that can accommodate a sleeve. The wrench body and the handle part are two separate parts, which are connected together in a detachable manner. At the same time, the handle part is also a hollow structure, and the hollow part of the handle part and the hollow part of the wrench body are used to accommodate the sleeve. The entire space of the frame; the sleeve frame is in the shape of expanding in the middle and gradually tapering toward both ends; compared with the prior art, the handle part of the present invention can also be used as the sealing part of the sleeve frame, and only needs to be unscrewed and operated during use The handle part that is fully in contact with the operator's hand is sufficient, and there is no need to pull out the entire socket frame every time, which is labor-saving and convenient to operate; the shape of the socket frame expands in the middle and gradually tapers toward both ends and the design of two metal inserts , not only can make the overall compressive strength of the wrench uniform, but also can make the connection between the handle part and the wrench body more firm and stable.

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...

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
