The utility model relates to a rationally, simple structure makes easily, labour saving and time saving, convenient to use, work efficiency is high.

Description

Adjustable wrench with rotatable tail part having ratchet wrench function

Technical Field

The utility model belongs to the technical field of manual hardware and tools's technique and specifically relates to a rotatable afterbody has monkey wrench of ratchet spanner function has monkey wrench and ratchet function, and the ratchet function of afterbody has improved work efficiency greatly, and it is big to use the moment of torsion, and rotatory afterbody function makes this instrument can be in more local uses that have the barrier.

Background

At present, a common adjustable wrench can assemble and disassemble fasteners such as bolts, nuts and the like. The clamping and loosening speed of the common adjustable wrench is slow in the assembling and disassembling process, the working efficiency is influenced, and the adjustable wrench is inconvenient to use or even cannot be used in places with obstacles.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing the adjustable wrench with the rotatable tail part having the ratchet wrench function.

The utility model provides a technical scheme that its technical problem adopted is: the ratchet wrench is characterized in that the wrench opening is matched with a large hole in the head of the wrench body and is simultaneously meshed with a worm installed in a square hole in the head of the wrench body, so that the function of an adjustable wrench is realized, the ratchet inner hexagonal wrench block is installed in a mounting hole in the tail of the wrench body through the check ring, and the pawl, the fixing piece and the second spring are installed in a groove beside the mounting hole in the tail of the wrench body.

The tail part is connected with the wrench body through the first pressing block, the second pressing block, the first positioning shaft, the second positioning shaft and the third spring, the first positioning shaft, the second positioning shaft and the tail part are all provided with meshing teeth, the first positioning shaft and the second positioning shaft are pressed down to separate the meshing teeth, the tail part can be rotated by a certain angle, the first positioning shaft and the second positioning shaft are loosened, the teeth are meshed again, the position of the tail part and the wrench body is fixed, and the wrench can be used in more occasions with obstacles and the like.

The utility model relates to a rationally, simple structure, easy manufacturing, labour saving and time saving has monkey wrench and ratchet function, and the ratchet function of afterbody has improved work efficiency greatly, and the use moment of torsion is big, and rotatory afterbody function makes this instrument can be in having more places uses of barrier.
