The left servo drive unit 2 and the left screw rod 9 are transmission connected. Therefore, when the left servo unit is started, it can drive the left screw rod 9 to rotate on the left base and the middle base 11.

[0032] When the left screw rod 9 rotates, the left screw rod 9 acts on the left clamping arm 7. Since the left clamping arm 7 is connected to the long guide rail 4 through the left slider 5, when the left screw rod 9 rotates, the left clamping arm 7 moves along the length direction of the long guide rail 4.

When the left screw 9 rotates, the left screw 9 acts on the left clamping arm 7. Since the left clamping arm 7 is connected to the long guide rail 4 through the left slider 5, when the left screw 9 rotates, the left clamping arm 7 moves along the length direction of the long guide rail 4. When the rotation direction of the left screw 9 is changed, the movement direction of the left clamping arm 7 also moves in the opposite direction.
