[0034] The head 7a of the adjusting screw 7 is preferably provided with a hexagonal recess to facilitate the adjustment of the adjusting screw 7 by a hexagonal wrench. The head 7a of the adjusting screw 7 is rotatable in the fixing seat 5, and since the threaded rod 7b of the adjusting screw 7 is threadedly connected with the sliding seat, the rotation of the threaded rod 7b is converted into the linear motion of the sliding seat during the adjustment of the adjusting screw 7, thereby achieving the adjustment of the torsion spring 4.

[0035] The adjusting assembly further comprises a clamping spring 11 arranged between the head 7a of the adjusting screw 7 and the fixing seat 5. As shown in Figures 1-3 , the clamping spring 11 and the limiting portion 7c fix the adjusting screw 7 on the fixing seat 5.
