When in use, when the sliding plate 13 slides forward until the second rack 1302 is meshed with the driven gear 16, the driven gear 16 is driven to rotate, so that the rotating rod 17 and the laser head 18 are driven by the driven gear 16 through the No. 2 rotating shaft 15 to rotate in a vertical plane.

[0033] In specific use, first, the object to be printed is placed in the fixed disc 201, and the clamping block 203 fixes the object to be printed under the elastic expansion and contraction action of the spring 202, and then the motor 10 is started to drive the driving shaft 102 to rotate through the first shaft 101. Because the driving gear 102 is meshed and rotated with the fixed gear 8, and the fixed gear 8 is fixed on the lower surface of the platform 4, the motor 10 drives the rotating mechanism 11 to rotate in the horizontal plane. While rotating, the motor 10 also drives the cylinder 7 to rotate in the rotating groove 5 through the telescopic rod 9. When the specified horizontal position is reached, the motor is turned off and the starting gas is turned off. Cylinder 7, cylinder 7 pushes the motor 10 and the rotating mechanism 11 to a predetermined vertical height through the telescopic rod 9, and then the motor 10 is started again. The driving gear 102 can drive the sliding plate 13 to slide back and forth in the sliding groove 12 by engaging with the rack 1 1301. When the sliding plate 13 slides forward to the time when the rack 2 1302 is engaged with the driven gear 16, the driven gear 16 is driven to rotate, so that the rotating rod 17 and the laser head 18 are driven by the driven gear 16 through the second rotating shaft 15 to rotate in the vertical plane, and finally the laser head 18 reaches the specified position in the vertical plane to determine the final printing position.
