Problems solved by technology
[0002] At present, there are many kinds of nut specifications for electric power maintenance. It is necessary to carry a corresponding number of wrenches to ensure maintenance, and it is heavy to carry; it is time-consuming and laborious to choose a suitable wrench from many wrenches; most universal wrenches fit different nuts. Poor, easy to slip during use, poor applicability; some chain wrenches, in order to clamp nuts of different sizes, the telescopic mechanism drives one end of the chain to change the position of the wrench, due to the instability of the telescopic mechanism, the chain The degree of fit with the nut decreases, that is, the tightness of the chain to the nut decreases, and it is easy to slip during use

The invention discloses a power maintenance wrench, and relates to the technical field of electric maintenance tools. The power maintenance wrench comprises a sleeve, a chain, a rotating rod and a clamping piece arranged at the front end of the rotating rod, the two ends of the chain are hinged to the front end of the sleeve, the two ends of the chain are located on the two sides of the sleeve respectively, the rotating rod is in telescopic fit with the sleeve, and the clamping piece is located in the encirclement of the chain; and through the sleeve, the chain hinged to the two sides of the sleeve, the rotating rod and the clamping piece, nuts with various specifications and sizes can be installed or dismounted, and the power maintenance wrench is good in use effect and does not slip.
Description
technical field [0001] The invention relates to the technical field of electric power maintenance tools, in particular to an electric power maintenance wrench. Background technique [0002] At present, there are many kinds of nut specifications for electric power maintenance. It is necessary to carry a corresponding number of wrenches to ensure maintenance, and it is heavy to carry; it is time-consuming and laborious to choose a suitable wrench from many wrenches; most universal wrenches fit different nuts. Poor, easy to slip during use, poor applicability; some chain wrenches, in order to clamp nuts of different sizes, the telescopic mechanism drives one end of the chain to change the position of the wrench, due to the instability of the telescopic mechanism, the chain The degree of fitting with the nut is reduced, that is, the tightness of the chain to the nut is reduced, and it is easy to slip during use. Contents of the invention [0003] The technical problem to be s...
