Moving plate is ratchet, and the tooth surface of the ratchet is the arc surface of smooth transition, and the adjusting cavity side is equipped with screw thread, the spiral shell
Line is equipped with circular pit, the pit side with being threadedly engaged for lid outer rim, the described one end covered and cooperated with adjusting cavity that adjusts is adjusted
Face is inclined-plane, and the pit centres are equipped with axis hole, and the adjusting exterior surface, which is equipped with, adjusts boss, and the adjusting cavity bottom is equipped with
Boss, the boss top edge have been evenly arranged pilot hole, and the guiding axially bored line extends along boss axis direction, described to lead
Xiang Kongzhong is equipped with spring, and the spring is equipped with detent ball close to one side pressure of brake disc, and the spring is equipped with close to lid one end is adjusted
Ball is adjusted, the boss center is equipped with through-hole and clamping head one end fits, and the brake disc is equipped with the one end for adjusting lid cooperation
The shaft hole matching that shaft, the shaft and adjusting cover, the driving end are combined with the end face for adjusting lid equipped with along adjusting cavity side
The graduation mark of fate cloth.
Further, axle sleeve is equipped in the through-hole.
Further, the adjusting caping end, which is equipped with, adjusts boss.
The invention has the benefit that cover that adjust preset force in Wrench head convenient to use using adjusting, regulating mechanism compared with
Small precision prevents regulating mechanism from deforming the preset torque power upper limit simultaneously and mentions convenient for guaranteeing using the adjusting uniform bearing torque of ball
It is high.
