Abstract

The invention provides a ratchet wheel monkey wrench which comprises a wrench body, a ratchet wheel, a locating part and a moving part. The wrench body is provided with a rotating axis. A fixed clamping portion is arranged on the inner circumferential edge of the ratchet wheel. The locating part is arranged on the ratchet wheel. The locating part is arranged on the inner circumferential edge of the ratchet wheel and is movably connected with the locating part. The moving part is provided with a moving clamping portion. A tool trough is formed between the moving clamping portion and the fixed clamping portion so as to provide the tool sleeving function, and therefore the moving part is controlled so as to adjust the size of the tool trough. Thus, the ratchet wheel monkey wrench is used in cooperation with workpieces of different sizes, and the practicality of the ratchet wheel monkey wrench is increased.

Description

technical field [0001] The invention relates to a ratchet wrench structure, in particular to a ratchet adjustable wrench that can be adjusted to match the size of different workpieces. Background technique [0002] A general ratchet wrench has a handle and a head, and the head has a hollow operating part. When operating, the hollow operating part of the head is sleeved on the screw, and the handle is turned to rotate the head to rotate the screw. Locking or loosening; since the hollow operating part is of a fixed size, it can only be used for screws of the corresponding size. Therefore, when there are screws of different sizes to be locked or loosened, it is necessary to use the corresponding The size of the ratchet wrench makes it inconvenient to use. [0003] In order to solve the foregoing problems, U.S. Patent No. 4,838,132 provides an adjustable twisting tool, the hollow operating portion of the head has an adjusting screw, and the end of the adjusting screw can abut a...
