Description

Quick adjustment wrench

The invention relates to the construction of a wrench, in particular to a quick adjustment wrench.

The existing adjustable wrench is provided with a fixed cymbal on the top of the wrench body, and a movable cymbal that can slide left and right relative to the fixed cymbal, corresponding to the tooth row at the bottom of the movable cymbal, and a screw engaged with the tooth row at the top of the wrench. When the above-mentioned existing adjustable wrench is used, the screw is rotated by the thumb, the movable cymbal is driven by the rotation of the screw, and the fixed component such as a nut or a bolt is clamped by the movable cymbal with the fixed cymbal, and is fixed by the rotation of the movable wrench. The component is rotated tightly or loosely.

Although the above-mentioned adjustable wrench can achieve the effect of rotating the fixing component, since the movable jaw needs to be driven by rotating the screw, it is necessary to rotate the screw repeatedly in use, resulting in a long operation time, and in addition, the thumb rotating screw is frictional. Therefore, the friction of the fingers may be broken during the rotation process, and the screw of the old design is an exposed component, which is easy to get dust, and the screw needs to be regularly lubricated to facilitate the rotation, so it is also necessary to maintain it frequently for the convenience of the user. It makes the existing monkey wrench more troublesome and inconvenient to use.

Since the existing adjustable wrench needs to repeatedly rotate the screw with the thumb to move the movable jaw to clamp or release the fixing component, it has the disadvantages of slow speed, easy injury to the hand and oil maintenance of the parts during the operation; The invention is provided with a structure for quickly releasing and pulling the movable cymbal, which can achieve the effect of quick operation with one hand, easy injury to the hand and no need for frequent oil maintenance.
