Problems solved by technology

Since the bolt head is made of aluminum, magnets cannot be used, so it is not easy to collect
Therefore, the bolt heads will fall in the car or on the production line and can only be collected manually, with low efficiency and poor effect
Once it is not cleaned in time, it will affect the production quality of the car, or it will fall into the production line equipment, causing equipment failure to stop production

Embodiment Construction

[0037] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0038] In the present disclosure, unless otherwise stated, the directional words used such as "front, back" generally mean that the end relatively close to the bolt is the front and the end relatively far is the back in the working state of the socket wrench. . The term "working cavity" refers to a cavity used for accommodating bolt heads and shape-matched with the bolt head, and "collecting cavity" refers to a cavity used for collecting broken bolt heads.

[0039] Such as Figure 1 to Figure 4 As shown, a socket wrench is shown, wherein the socket wrench includes a socket body 1, a closure member 2, an elastic holding structure 3 and a connecting rod 8. The socket...

Abstract

The invention relates to a sleeve wrench. The sleeve wrench comprises a sleeve body (1), a seal part (2), an elasticity keeping structure (3) and a connecting rod (8). The sleeve body comprises a work cavity (1a) and a collection cavity (1b) which are communicated, the work cavity is formed in the front end of the sleeve body and is provided with a polygonal section, the seal part is used for sealing the rear end of the sleeve body and is detachably connected with the sleeve body, one end of the connecting rod is connected with the seal part, the other end of the connecting rod is connected with a power device, and the elastic keeping structure is arranged at the front end of the sleeve body and is used for elastically abutting against a bolt head (4) entering the work cavity. According to the sleeve wrench, an anti-theft bolt can be tightened, a bolt head of the twisted-off anti-theft bolt can be conveniently and efficiently collected, the bolt head can be prevented from falling in a car or on a production line, and the wrench also can be used for mounting and dismounting of common bolts and nuts.

Description

Technical field [0001] The present disclosure relates to the field of tools, in particular to a socket wrench. Background technique [0002] In the automobile manufacturing process, when installing the inlet high-pressure air duct interface of the supercharged engine on the assembly line of the final assembly shop, the interface is fixed with an anti-theft bolt, and the bolt head of the anti-theft bolt is made of aluminum material. During installation, the operator first assembles the inlet high-pressure air duct interface to the installation position, and then uses a pneumatic tool to tighten the anti-theft bolt at the duct interface. When the torque reaches a predetermined value, the bolt head of the anti-theft bolt will be broken. Since the bolt head is made of aluminum, magnets cannot be used, so it is difficult to collect. Therefore, the bolt heads will fall in the car or on the production line and can only be collected manually, which is inefficient and inefficient. Once...
