Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of mechanical tools, and more specifically, relate to a retractable multi-purpose portable disassembly and assembly device. Background Art

[0002] A socket wrench is composed of multiple socket heads with hexagonal holes or twelve-angle holes, as well as a rotating handle, a connecting rod and other components. It is particularly suitable for disassembling and tightening accessories that are located in very narrow spaces or deeply recessed. In mechanical work, it is often necessary to use a socket wrench to disassemble and tighten accessories. The structure of the socket wrench widely used in production and life is generally fixed, and it is impossible to disassemble and tighten accessories at different depths by adjusting the length of the socket wrench connecting rod. Construction workers are often required to carry a variety of socket wrenches of different lengths to complete the task of disassembling and tightening accessories at different depths. In addition, since the length of the existing socket wrench connecting rod cannot be adjusted, it is inconvenient for construction workers to carry socket wrenches for work, which not only increases the cost of use, but also increases the labor intensity of construction workers, which is not conducive to improving work efficiency.

[0003] The commonly used solution on the market at present is to make the socket wrench retractable, and through the cooperation of a telescopic rod or a slide rail, the length of the front end of the socket can be changed, and the length of the socket wrench connecting rod can be adjusted over a large range, so that accessories at different depths can be removed and tightened, effectively reducing the number of socket wrenches that construction workers need to carry, and by adjusting the length of the socket wrench connecting rod, it is convenient for construction workers to carry socket wrenches to work, which not only reduces the cost of use, but also reduces the labor intensity of construction workers, which is conducive to improving work efficiency.

[0004] However, when such a socket wrench is used to disassemble accessories of different sizes, more sockets are required, which is not convenient to carry. Moreover, when it is used to disassemble accessories that are tightly installed, it cannot generate a large torque, which makes it difficult to disassemble the accessories. Therefore, a retractable multi-purpose portable disassembly and assembly device is needed, which is retractable and easy to carry, and can change the lever arm to generate a larger torque.
