[0034] During specific use, the patient places the limb on the soft rubber pad 1, and then adjusts the position of the rotating automatic nail removal mechanism 4 according to the position of the screw. If the longitudinal position of the rotating automatic nail removal mechanism 4 needs to be adjusted, it is only necessary to first place the longitudinal locking component 6 in the initial position, that is, to pull the two moving blocks 605 outward, and the moving block 605 drives the fixed block 606 and the trapezoidal block 604 to move outward together until the fixed block 606 is in close contact with the inner wall of the hollow column 501, and then rotate the rotating plate 701 to the desired position, and the rotating plate 701 drives the arc block 702 to rotate, and the arc block 702 can drive the entire rotating automatic nail removal mechanism 4 to rotate through the rectangular frame 703 and the rectangular box 705. At the same time, the rotating plate 701 drives the rotating shaft 506 to rotate, the rotating shaft 506 drives the columnar gear 507 to rotate, and the columnar gear 507 drives the rack 504 and the movable plate 502 to move along the limit block 503.

[0035] If it is necessary to adjust the lateral position of the rotating automatic nail removal mechanism 4, it is only necessary to first place the lateral locking component 8 in the initial position, that is, rotate the screw rod 801, the screw rod 801 drives the pushing block 802 to move upward, the elastic force of the spring 808 in the compressed state is released, and the spring 808 pushes the end short plate 805 to move along the rectangular short column 806 toward the pushing block 802, and the short plate 805 drives the trapezoidal plate 804 and the arc rubber block 807 to move toward the pushing block 802. When the pushing block 802 moves to the top of the rectangular box 705, the arc rubber block 807 is completely removed from the fixing groove 708, and the fixing of the current lateral position can be released. The rectangular box 705 then drives the rectangular frame 703 and the arc-shaped slider 704 to move along the arc-shaped groove 707 until the rotating automatic nail removal mechanism 4 and the screw are in the same straight line position, and then the screw rod 801 is rotated in the opposite direction, the screw rod 801 drives the pushing block 802 to move downward, and the pushing block 802 pushes the trapezoidal plates 804 on both sides to move outward, and the trapezoidal plates 804 drive the short plates 805 and the arc-shaped rubber blocks 807 to move outward together until the arc-shaped rubber blocks 807 are stuck in the fixing groove 708, and the current lateral position of the rotating automatic nail removal mechanism 4 can be fixed by the friction between the arc-shaped rubber blocks 807 and the fixing groove 708.

[0036] After adjusting the position, the screws can be taken out, and the electric telescopic rod 901 is started. The electric telescopic rod 901 drives the circular block 902 and the Z-shaped plate 903 to move downward together. The circular block 902 drives the clamping ring 905 to move downward, that is, drives the entire automatic clamping assembly 10 to move downward together. The Z-shaped plate 903 drives the motor 904 and the clamping ring 906 to move downward together. After the automatic clamping assembly 10 is moved to a suitable position, the electric telescopic rod 901 is stopped, and the electric telescopic rod 1001 is started. The electric telescopic rod 1001 drives the movable block 1004 to move upward, and the movable block 1004 drives the connecting rod 1003 Rotate inward, connecting rod 1003 drives clamping jaw 1002 to retract inward until clamping jaw 1002 clamps the screw, start motor 904 and electric telescopic rod 1 901 at the same time, motor 904 drives snap ring 2 906 to rotate, snap ring 2 906 drives snap ring 1 905 to rotate through transmission belt, snap ring 1 905 drives the whole automatic clamping assembly 10 to rotate, so that clamping jaw 1002 drives the screw to be screwed, and at the same time, electric telescopic rod 1 901 drives the whole automatic clamping assembly 10 to move upward, so that clamping jaw 1002 drives the screw to be screwed while driving the screw to move outward from the body, so that the screw can be taken out.
