[0028] Further, the electric push rod 2 can drive the Z-axis lifting seat 3 to rise or fall, thereby adjusting the height of the Y-axis sliding seat 8.

[0029] Furthermore, the first motor 16 drives the first drive shaft 17 to rotate, which can drive the first gear 18 to rotate. Since the first gear 18 is engaged with the first rack 11, when the first gear 18 rotates, it will drive the first rack 11 to move left and right, and then drive the Y-axis sliding seat 8 to move along the direction of the Y-axis.
