[0026] Specifically, the starting motor 2 drives the first connecting rod 3 to rotate, the rotation of the first connecting rod 3 drives the cross shaft 4 to rotate, and the second connecting rod 5 is rotated, the rotation of the second connecting rod 5 drives the third connecting rod 6 to rotate and the connected cross shaft 4 is rotated, and at the same time drives the driven rod 7 and the clamping jaw 10 to rotate, the movement of the electric slider 9 causes the clamping jaw 10 to move in the longitudinal direction, the starting motor 14 causes the rotating rod 18 to rotate and drives the second gear 17 to rotate, the second gear 17 rotates on the first gear 16 and drives the second housing 11 to rotate, thereby causing the clamping jaw 10 to move in the lateral direction.
[0027] Reference Figure 2 and Figure 4 The outer wall of the first housing 1 is fixedly connected to a base 19, the inner wall of the base 19 is fixedly connected to a spring rod 20, the lower surface of the spring rod 20 is fixedly connected to a clamping block 21, and the clamping block 21 is slidably connected to the inner wall of the base 19; the outer wall of the clamping block 21 is slidably connected to a limit block 22, the inner wall of the limit block 22 is fixedly connected to a sliding rod 23, and the outer wall of the sliding rod 23 is slidably connected to a reset block 24;
[0028] Specifically, by pressing the third shell 27 downward to push the drive shaft 25 to move downward, the reset block 24 slides on the outer wall of the blocking block 21.
