[0039] Working principle of the utility model: The utility model designs a torque adjustable fitter wrench, the specific structure is as shown in the attached manual Figure 1-6As shown, in the technical solution, through the mutual cooperation between various structures, when the torque needs to be adjusted, the torque adjusting handle 20 is threadedly connected with the right side of the threaded base 23, so that the torque adjusting handle 20 can be rotated, and the torque adjusting handle 20 drives the threaded block 21 to rotate through the second fixed block 19, and the threaded piece 22 is threadedly connected with the right end of the torque adjusting handle 20 to support the rotation of the torque adjusting handle 20, and the torque adjusting handle 20 can push the threaded rod 17 to rotate to the left to squeeze the torsion spring 16, and the tension of the torsion spring 16 is used to store the torque required to be twisted. When the required torque is reached, the torsion spring 16 loses its tension, causing the fixed block 14 and the left groove of the spacer block 15 to fall off and tilt. , so that the right end of the wrench fixing rod 2 hits the inner wall of the fixing tube 1 to prevent excessive torque. When the size of the wrench needs to be adjusted, the rotating rod 4 is rotated, and the rotating rod 4 is used to drive the gear 5 to rotate the meshing toothed disc 6, so that the toothed disc 6 drives multiple rotating wheels 7 to mesh and rotate, and multiple rotating wheels 7 simultaneously drive the rack 8 to mesh and move, and the movement of multiple racks 8 drives the sliding plate 9 to slide inside the slide rail 10, so that multiple clamping rings 11 can clamp bolts or nuts.
