Abstract

The invention discloses a multifunctional wrench, which comprises a casing and a chain. A slide rail is arranged on the inner wall of the casing. The slide rail is provided with a slider thereon. Theslider is connected with one end of a screw. The casing is provided with a threaded hole at one end and with a chain outlet at the other end. The other end of the screw passes through the threaded hole to be fixedly connected with a handle. One end, far from the screw, of the slider is connected fixedly with one end of the chain. The casing is provided internally with more than one set of telescopic baffles. Both ends of the telescopic baffles are fixedly connected with the inner wall of the casing and the slider, respectively. The telescopic baffles are provided with through holes. The chainpasses through the through holes in each set of the telescopic baffles sequentially and extends out of the casing through the chain outlet. The chain has an S-shaped moving trajectory. One end, extending out of the casing, of the chain is fixedly connected with the inner wall of the casing. The multifunctional wrench can be applied to different types of bolts and nuts, and is suitable for broken bolts.

Description

technical field [0001] The invention relates to a wrench, in particular to a multifunctional wrench. Background technique [0002] During maintenance and assembly of existing machinery, screws and nuts need to be disassembled. Since the specifications of the screws and nuts vary, various types of wrenches are required for disassembly. Secondly, bolts and nuts are sometimes damaged, and it is difficult for ordinary wrenches to loosen them. Moreover, maintenance workers need to carry various wrenches during maintenance, which increases the load of the maintenance workers, and constantly changing the wrenches also causes low work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional wrench, which can be used for different types of bolts or nuts, and is suitable for damaged bolts. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A multifunctional wre...
