Problems solved by technology

[0004] Aiming at the technical problem in the prior art that each rotation of the ratchet wrench can only make the screw rotate a small thread stroke when tightening the screw, and cannot take advantage of the advantages of the ratchet wrench, the present invention provides a special visual wrench for limited space. The quick wrench adopts gear right-angle transmission, which improves the transmission stability. The bracket and fixing mechanism are used to realize a stable transmission rod, which can efficiently and quickly complete production operations in a small space, and can realize visual operation, which is convenient for the screw position in a small space. Finding and alignment, with a wide range of applicability in the field of industrial assembly

Abstract

The invention provides a special visual fast wrench in a limited space. The special visual fast wrench comprises a driving mechanism and a transmission mechanism. A fixing mechanism is arranged out ofthe transmission mechanism, a reversing mechanism is arranged at the end, far away from the driving mechanism, of the transmission mechanism, a fastening head is arranged at the end, far away from the transmission mechanism, of the reversing mechanism, a display screen is arranged on the upper part of the fixing mechanism, a camera is arranged next to the fastening head, and the camera is electrically connected to the display screen. The special visual fast wrench can loosen and tighten a screw in the limited space quickly, so that the problem that the screw loosening and tightening efficiency is reduced as a twisting handle is affected by two side walls in a twisting direction when a common ratchet wrench is used is solved. The special visual fast wrench can fit space structures with different wall widths and depths. For places which cannot be reached by a human eye vision, the camera is arranged to feed the places back to the display screen, so that an operator can find the positionof the screw. The special visual fast wrench is convenient to carry and quite convenient to mount and use, and has wide adaptability in the field of industrial assembly and production and life.

Description

technical field [0001] The present invention relates to the technical field of tools, in particular, the present invention specifically relates to the technical field of wrenches. Background technique [0002] A wrench is a common tool for removing and tightening bolts or nuts. Some mechanical equipment, due to the particularity of its structural design, will have some screws in a relatively limited space, such as a hollow space in a cube with only one side open. Use a ratchet wrench to tighten the screws in this space, and the ratchet will be locked every time. The power-assisted rotation in the direction of anti-torque force can only rotate a small angle due to the limitation of the left and right walls of the cube space. Therefore, when tightening the screw, each rotation of the ratchet wrench can only make the screw rotate a small amount of thread travel, and cannot exert its full potential. Advantages of the ratchet wrench. [0003] At present, although there are some...
