[0016] By adopting the above technical solution, when the staff rotates the rotating rod, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby reducing the probability of the rotating rod sliding, thereby reducing the probability of the second gear and the first gear separating from each other, and thereby improving the stability of the device.

[0017] Furthermore, the limiting rod is stretched outwards close to the limiting groove, and the limiting rod and the limiting groove match each other.

[0018] By adopting the above technical solution, the limiting rod is stretched outward near the limiting groove so that the limiting rod limits the second gear, thereby reducing the probability of the second gear and the first gear being separated from each other, thereby improving the stability of the device.

The sleeve 13 is a round rod-shaped structure with an opening at the lower end, the axis of which is vertical, and two sleeves 13 are provided and symmetrically installed on the bottom surface of the support plate 12. The sleeve rod 14 is a round rod-shaped structure, the axis of which coincides with the axis of the sleeve 13, and two sleeve rods 14 are provided and are respectively slidably arranged in the sleeve 13. The mounting plate 15 is a rectangular plate structure, and the mounting plate 15 is fixedly mounted on the bottom surface of the two sleeve rods 14. The cross section of the U-shaped frame 16 is U-shaped, and the U-shaped frame 16 is mounted on the bottom surface of the mounting plate 15. Two connecting members 17 are provided and mounted on the side walls of the U-shaped frame 16 close to each other in the vertical direction, and two printing rollers 18 are provided and rotatably mounted on the two connecting members 17 respectively, and their axes are horizontal.

[0029] When the staff needs to print the printed workpiece, the staff needs to place the printed workpiece on the fixed plate 1. Then, the staff needs to slide the sleeve rod 14 downward, so that the mounting plate 15, the U-shaped frame 16, the connecting member 17 and the printing roller 18 move downward, so that the printing roller 18 abuts against the upper surface of the printed workpiece, and then the printing roller 18 prints the printed workpiece. In this process, the printed workpieces are continuously reduced, and the printing roller 18 is always pressed against the upper surface of the printed workpiece under the action of the adjustment component 2, without the need for manual adjustment by the staff, thereby reducing the difficulty of the staff's work.
