Description

technical field [0001] The invention relates to an adjustable wrench, in particular to a quick adjustable wrench. Background technique [0002] Existing adjustable wrench is generally made up of wrench body, adjustable wrench mouth and drive rod rack adjustment mechanism. When in use, the transmission rod needs to be rotated in a circle by hand to make the movable wrench move, so that the wrench is opened. The disadvantage of this structure is that the opening and contraction of the wrench is adjusted by rotating the transmission rod rack by hand to cooperate with the movement of the movable wrench, which is slow and inefficient, especially when it is frequently used in different sizes. Inconvenience. Contents of the invention [0003] The object of the present invention is to provide a quick adjustable wrench to solve the problem that when using the adjustable wrench in the prior art, the transmission rod needs to be rotated by hand in circles to make the movable wrench...
