Problems solved by technology

[0002] A wrench is a commonly used dismounting tool. The more commonly used tools for disassembling bolts and nuts are pipe wrench or hexagon socket wrench. The pipe wrench will damage the conical head nuts and bolts when disassembling them. Conical surface, not conducive to multiple disassembly
The inner hexagon wrench can only be used for the disassembly and assembly of the inner hexagon bolts, and once the inner hexagon is damaged, the disassembly will not be completed
Due to the limitation of the disassembly space, when the existing wrench rotates the nut, the wrench must be removed every time it is rotated, repositioned and then rotated. The disassembly efficiency is low, and if the space is small, it is more difficult to operate

Abstract

The invention discloses a nut wrench for assembling and disassembling cone head nuts. The nut wrench comprises a handle, a wrench body and a claw, the handle is connected with the wrench body, a firstthrough hole is formed in the center part the wrench body, a cone-shaped gap is arranged at one end of the first through hole, a radial-shaped circular groove is formed in the radial direction in thecircular surface of the cone-shaped gap in a through mode, one end of the claw is arranged in the circular groove in a clamping mode, the claw can rotate around the center of the cone-shape gap in abidirectional direction, the other end of the claw extends out of the circular groove to an inner cavity of the cone-shaped gap, and a first bulge and a second bulge are arranged on one end of the claw extending out of the circular groove. Continuous whole cycle rotation of the nuts within a limited rotating angle can be achieved through the nut wrench, separation of the wrench from the nuts is not necessary, and the working efficiency is greatly improved. The nut wrench is easy to use, has a long cycle and does not easily damage the surface of the nuts to be disassembled.

Description

technical field [0001] The invention relates to a wrench, in particular to a nut wrench for disassembling conical head nuts. Background technique [0002] A wrench is a commonly used dismounting tool. The more commonly used tools for disassembling bolts and nuts are pipe wrench or hexagon socket wrench. The pipe wrench will damage the conical head nuts and bolts when disassembling them. The conical surface is not conducive to multiple disassembly and assembly. The inner hexagon wrench can only be used for the disassembly and assembly of the inner hexagon bolts, and once the inner hexagon is damaged, the disassembly will not be completed. Due to the limitation of disassembly space, when the existing wrench rotates the nut, the wrench must be removed every time it is rotated, repositioned and then rotated. The disassembly efficiency is low, and if the space is small, it is more difficult to operate. Contents of the invention [0003] The invention provides a nut wrench for...
