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 fast labor-saving wrench for electric power maintenance. Background technique [0002] Wrench is a common tool in power maintenance work. Power maintenance, especially field power maintenance work, has the characteristics of high-altitude operation, easy rusting of bolts and nuts, narrow working space and great danger. The current wrench used by electricians cannot fully meet these characteristics. Job characteristic requirements. First of all, the current electrician's wrench is generally an ordinary insulated wrench. This kind of wrench has the disadvantages of large volume and labor. Moreover, when rotating the bolt and nut, its rotation radius is generally the length of the wrench, which further expands the use radius of the wrench. When an electrician disassembles bolts and nuts in a small space, if there is no wrench of appropriate size, it is usually n...
