Rapid labor-saving spanner for electric power maintenance

Abstract

The invention discloses a rapid labor-saving spanner for electric power maintenance, and belongs to the technical field of general tools. The rapid labor-saving spanner solves the defects that in theprior art, the spanner is large in size, incapable of saving labor, low in efficiency and incapable of recovering a bolt nut; the spanner mainly comprises a spanner head, a transmission device and a handle, wherein the spanner head comprises a clamp head and an inserting rod, the transmission device comprises a sleeve, one end of the sleeve is provided with a sleeve inner cavity, the inserting rodcan be inserted into the sleeve inner cavity, a partition plate, a first planetary speed reducing device and a second planetary speed increasing device are fixedly installed inside the sleeve in sequence, and a guide groove is formed in the partition plate; and the guide groove is internally provided with an elastic piece and a rotating shaft, the first planetary speed reducing device comprises afirst sun wheel and a plurality of first planet wheels, a first top plate is installed at one end of the sleeve in a sleeve mode, a second sun wheel is fixedly installed in the middle of the first top plate, and the second planetary speed increasing device comprises the second sun wheel, a rotating cylinder and a plurality of second planet wheels.

Description

technical field [0001] The invention belongs to the technical field of general tools, and in particular relates to a quick and labor-saving wrench for electric power maintenance. Background technique [0002] Wrench is a common tool in electric power maintenance work. Electric power maintenance, especially field power maintenance work, has the characteristics of high-altitude operation, easy rust of bolts and nuts, small working space and high danger. The current wrenches used by electricians cannot fully meet these requirements. job requirements. First of all, the current electrician's wrench is generally an ordinary insulated wrench. This wrench has the disadvantage of being large and laborious, and when rotating the bolt and nut, the rotation radius is generally the length of the wrench, which further expands the use radius of the wrench. When electricians disassemble bolts and nuts in small spaces, if there is no suitable size wrench, they usually need to disassemble pe...
