Fastener disassembly spanner

Abstract

The invention discloses a fastener disassembly spanner. The fastener disassembly spanner comprises a first holding rod taking the shape of a hollow pipe, a swing rod hinged to one end of the first holding rod, a ratchet mechanism arranged at the other end of the first holding rod and provided with a clamping port capable of clamping a fastener, and a stay wire connected to the ratchet mechanism by one end and connected with the swing rod by the other end after penetrating through the first holding rod so as to enable the ratchet mechanism to perform an intermittent equidirectional movement through the swing rod. The swing rod and the ratchet mechanism connected through the stay wire are respectively arranged at the two ends of the first holding rod, so that the clamping port on the ratchet mechanism can disassemble the fastener; the structure is reliable; the operation is convenient and flexible; on the one hand, the trouble of incapability of smoothly disassembling the fastener by a general spanner due to the operation space limitations in the maintenance and production process can be removed; and on the other hand, the disassembly difficulty caused by the working body limitations of operators is effectively solved; and the fastener disassembly spanner can be suitable for various complex environments.

Description

technical field [0001] The invention belongs to the technical field of fastener dismounting tools, in particular to a fastener dismounting wrench. Background technique [0002] Fastener is a general term for a class of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. Fasteners usually include screws, bolts, screws and nuts, of which hexagonal Head bolts and nuts are more commonly used. [0003] In the process of production and maintenance, a wrench is often used to disassemble the fastener. When the wrench cannot smoothly tighten or remove the fastener due to the limitation of the operating space, it will cause difficulty in disassembling the fastener. Contents of the invention [0004] Aiming at the technical problem in the prior art that the wrench is easily limited by space when disassembling fasteners, the present invention provides a fastening tool that is not limited by a narrow space and is convenient for operato...
