The invention discloses a quick-moving wrench, including a wrench, a wrench and a worm. The wrench head is provided with a transverse circular hole, the wrench is inserted into a transverse circular hole through its bottom circular shaft rack, the wrench head is also provided with a worm accommodation space, and the worm engages with the upper circular shaft rack of the wrench, and the worm accommodation space is provided. The worm clutch device includes a spring, a left steel ball and a right steel ball. The spring is installed in a central shaft hole opened by the worm. The left end of the spring is held against the left steel ball, the right end of the spring is held against the right steel ball, and the upper part of the left inner wall of the worm accommodation space and the upper part of the right inner wall of the worm accommodation space are simultaneously arranged. A corresponding arc-shaped long groove is provided, and the left steel ball and the right steel ball are closely attached to the inner wall of the corresponding arc-shaped long groove under the action of the spring. The invention has the advantages of reasonable design, simple structure, easy manufacture, time-saving and labor-saving, quick adjustment of the opening quantity by moving the worm up and down, convenient use and high working efficiency.
