Screwing the screwdriver rod 6 to drive the screw rod 8 to rotate upwards to a designated position, and taking out the screwdriver rod 6 after screwing to a proper position; then the screw cap 7 is required to be screwed down, and the screw rod 8 is positioned;
Before the nut 7 is screwed down, the force required by the nut with large model is large according to the size and the position of the nut 7, the compression amount of the spring is increased, the force required by the nut with small model is small, and the compression amount of the spring is reduced; the position of the pressing tube 31 is changed, so that the moment of the sleeve is changed, the position of the pressing tube 31 can determine the expansion and contraction amount of the spring 32, and the force applied by the torsion transmission mechanism 3 is changed; the method comprises the following specific steps: holding the front sleeve 1 with one hand and holding the rear sleeve 2 with the other hand, keeping the front sleeve 1 motionless and screwing the rear sleeve 2, driving the adjusting head 52 to rotate by the rear sleeve 2, driving the adjusting tube 51 to rotate, and rotating the adjusting tube 51 around the connecting rod 411, wherein in the rotating process, the pressing tube 31 moves to the side B under the action of the matching force of internal and external threads, the pressing tube 31 moves transversely along the axis, the locking piece 311 moves along the sliding hole 11, and the rotation of the rear sleeve 2 can be stopped after the spring 32 is compressed to a designated position;
The nut is then started to be screwed down, specifically: when the front sleeve 1 is rotated and the rear sleeve 2 is kept still, the pressing pipe 31 is driven to rotate by the locking piece 311, when the pressing pipe 31 rotates, the pressing pipe 31 moves along the axis line to the side B and compresses the spring 32 under the action of internal and external thread forces of the pressing pipe 31 and the adjusting pipe 51, the spring 32 is pressed to the first rotating wheel 33 to apply force, the first rotating wheel 33 presses the ball 45, the ball 45 presses the second rotating wheel 42, meanwhile, the pressing pipe 31 rotates to drive the spring 32 to rotate in a follow-up mode, the spring 32 shortens while rotating, and the spring 32 drives the first rotating wheel 32 to rotate;
