Abstract

The invention discloses a flexible hook spanner. The flexible hook spanner is applicable to mounting and dismounting of machine tool spindle connecting rod nuts with different sizes and comprises a handle and a working part arranged at the front end of the handle, wherein the working part comprises a chain, a hook head, a chain wheel and a limiting block, the chain wheel is meshed with the chain and used for increasing / decreasing the length of the chain, and the limiting block is used for limiting rotation of the chain wheel. The flexible hook spanner can realize mounting and dismounting of connecting nuts with different diameter specifications by the aid of the flexible characteristic of the chain, and in combination with the replaceable characteristic of a clamping hook of the hook spanner, the spanner can be adapted to aperture sizes of nut unthreaded holes with different diameters.

Description

technical field [0001] The invention relates to a wrench in the mechanical field. More specifically, the present invention relates to a flexible hook wrench that accommodates spindle post nuts of different sizes. Background technique [0002] The Chinese patent with the patent number "CN201320009192.3" discloses an adjustable hook wrench, but it can only be disassembled for one type of connecting nut, and its scope of use is very limited. To connect nuts of different sizes, you need to prepare several hook wrenches of different specifications to complete the disassembly and assembly, which is very inconvenient to carry during equipment maintenance, and after the hook of the hook wrench is worn out, the entire hook wrench can only be scrapped . Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the presen...
