Abstract

The invention relates to an overhaul spanner with the nut preassembling and recycling function. The overhaul spanner comprises an operating rod and a sleeve assembly. The sleeve assembly is connected to the operating rod and comprises a sleeve body, elastic rings and movable contact blocks. The sleeve body is provided with axial containing holes and radial slippage holes. The radial slippage holes communicate with the axial containing holes. The movable contact blocks are in slippage connection with the radial slippage holes. When the elastic rings compress the movable contact blocks, the movable contact blocks stretch into the corresponding axial containing holes. The elastic rings are arranged on the periphery of the sleeve body in a sleeving mode, and the outer ends of the movable contact blocks are limited through the elastic rings. The overhaul spanner with the nut preassembling and recycling function is particularly suitable for production assembling and trouble shooting in a narrow space.

Description

technical field

[0001] The invention relates to an overhaul tool, in particular to an overhaul wrench with the functions of pre-installing and recovering nuts. Background technique

[0002] During the production, assembly and troubleshooting of power electronic equipment, a large number of bolts and nuts need to be installed or removed. Therefore, when designing power electronic products in the industry, it is necessary to reserve a large operating space for the wrench and the operator's arm. However, with the continuous development of the power industry, the volume of power electronic equipment is getting smaller and smaller, and the structure is becoming more and more compact, and there are often some connection locations with narrow spaces and hidden locations. Operators often drop small parts such as bolts and nuts due to greater difficulties when installing or dismounting the bolts and nuts at the above positions. This not only affects the production efficiency, but a...
