[0023] The working principle of the embodiment is as follows:

[0024] In operation, first install the handwheel clamp 2 on the output shaft of the electric wrench 1. The lower end of the jaw handle 4 of the handwheel clamp 2 is provided with a screw clearance cage 5 to avoid the screw on the manual valve. The fixed ring 6 and the rotating ring 7 of the handwheel clamp 2 are connected through the upper and lower toothed discs 15 and 14, realizing the rotation adjustment of the rotating ring 7. The rotation of the rotating ring 7 drives the clamp 11 on the jaw seat 8 to move, so that it can adapt to the different shapes and sizes of the handwheel 3.
