Abstract

The invention relates to the technical field of power maintenance and discloses a wrench for power maintenance. The wrench comprises an insulated handle. One side of the insulated handle is fixedly connected with a sleeve, and one side of the sleeve is fixedly connected with a telescopic device. One end of the telescopic device is fixedly connected with a first insulated plastic block, and one side of the insulated plastic block is fixedly connected with a ceramic baffle. One end of the ceramic baffle is fixedly connected with a work head, and a through groove is formed in the upper surface ofthe work head and internally provided with a gear. A sliding groove is formed in one side of the work head, and an adjusting rod is inserted in the sliding groove. The adjusting rod is engaged with the gear through a gear groove formed in one side of the adjusting rod. According to the wrench for power maintenance, through the arranged telescopic device, stretching out and drawing back of a handle rod and the sleeve can be adjusted according to the needs, and thus the overall length of the handle rod is adjusted, so that the labor-saving and rapid effects are achieved on bolt screwing and unscrewing during using of the wrench; and the problem that the handle rod cannot be adjusted, and thus use is inconvenient is solved.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a wrench for electric power maintenance. Background technique [0002] A wrench is a commonly used installation and removal tool that uses the principle of leverage to turn bolts, screws, nuts, and other hand tools that are threaded to hold the openings or casings of bolts or nuts. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank along the direction of thread rotation, and the bolt or nut can be twisted. Among the equipment where the staff perform assembly work, some equipment is located in an area with insufficient light. It is not easy to use a wrench. Repeated actions reduce work efficiency and lower safety performance, because the handle of the wrench ...
