[0007] Furthermore, the guide rod, the clamping arm, and the helical spring together form the clamping part, and the front end face of the outer wall of the vertical part of the clamping arm contacts the rear end face of the base block and the plate.

[0008] Furthermore, a threaded rod A rotates on the sliding seat A, and the threaded rod A is threadedly connected to the base block. An adjusting motor A is fixed to the right end face of the sliding seat A, and the output shaft of the adjusting motor A is fixed to the threaded rod A.
