Problems solved by technology

[0002] In the disassembly and assembly of screws, due to design defects or space limitations, there are dead angles in some screw disassembly positions. If you directly use a hexagonal wrench to disassemble, it is difficult to apply force
A ratchet wrench can solve this problem to a certain extent, but for those screws with large diameter and torque, directly using a ratchet wrench to disassemble them may cause their failure or reduce their reliability
Purchasing a complete set of ratchet wrenches for individual dead-end screws will increase production costs

Embodiment Construction

[0022] The invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, a torque connection structure is composed of a connecting plate 2, a force applying rod 1, a bushing 3, and a locking screw 4.

[0024] Such as figure 2 As shown, the connecting plate 2 is cylindrical, and there are a plurality of circumferential mounting holes C on its circumferential side, and an axial mounting hole B communicating with it is provided on the center line of each circumferential mounting hole, and each mounting hole is equal in size. The locking screws are installed through the rectangular grooves in cooperation with the axial mounting holes and the circumferential mounting holes.

[0025] Such as figure 1 and image 3 As shown, the force application rod 1 is partially installed in the circumferential installation hole C, and the part of the force application rod inserted in the circumferential installation hole is provid...

Abstract

The invention discloses a torque connecting structure. The torque connecting structure is composed of a connecting disc, force rods, bushings and locking screws, a plurality of circumferential mounting holes are formed in the connecting disc, axial mounting holes communicated with the circumferential mounting holes are formed in the circumferential mounting holes, rectangular grooves are formed inthe force rods, the force rods are partially mounted in the circumferential mounting holes, the bushings are mounted in the circumferential mounting holes, and the locking screws penetrates through the axial mounting holes and are inserted into the rectangular grooves. The torque connecting structure is combined with the corresponding 7 / T / +-shaped wrench, a booster sleeve is used, the detaching and installation space is small, the dead angle screw of a wrench arm force cannot be directly lengthened, and the torque connecting structure has the advantages of being high in bearing capacity, lowin processing cost, high in reliability and compact in structure and the like.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to an auxiliary assembly and disassembly tool for a wrench. Background technique [0002] In the disassembly and assembly of screws, due to design defects or space limitations, there are dead angles in some screw disassembly positions. If you directly use a hexagonal wrench to disassemble and assemble, it is difficult to apply force. A ratchet wrench can solve this problem to a certain extent, but for those screws with large diameters and torques, directly disassembling them with a ratchet wrench may cause their failure or reduce their reliability. Purchasing a complete set of ratchet wrenches for individual dead angle screws will increase production costs. Therefore, how to economically and reliably solve the problem of disassembly and assembly of individual dead-spot screws remains to be further studied. Contents of the invention [0003] The purpose of ...
