The limiting rod 18 and the limiting block 20 provided can limit the engraving head 5, thereby preventing the engraving head 5 from shaking when moving.

[0025] Please refer to Figure 1 、 Figure 4 and Figure 5 As shown in, the pushing mechanism 7 includes a bottom plate 25, an avoidance groove 26 and a driving cylinder 30. One side of the support frame 2 is fixedly installed with the bottom plate 25. Two groups of avoidance grooves 26 are penetrated and opened on the connecting frame 1.

A blanking groove 27 is penetrated and opened at the top of the connecting frame 1 and on one side of the workbench 6.

[0026] Among them, when there is a large amount of waste generated during the engraving process, the driving cylinder 30 is started to operate, and the driving cylinder 30 rises. Then it can push the workbench 6 to tilt along one side of the connecting frame 1. Then the waste on the workbench 6 can fall through the blanking groove 27. A collection box for collecting waste can be provided below the blanking groove 27, so as to discharge the waste centrally.

[0027] Please refer to Figure 1 and Figure 4 As shown in, the positioning mechanism 8 includes a second limiting rod 31, a third mounting bracket 32, a limiting sleeve 33 and a positioning rod 34.

Subsequently, the third mounting bracket 32 can drive the positioning rod 34 away from the inside of the workbench 6, facilitating one end of the workbench 6 to tilt up. After the waste is discharged, rotating the adjusting threaded sleeve 36 in the reverse direction can make the positioning rod 34 reinsert into the inside of the workbench 6 for limiting.

[0029] During use, first, when the engraving head 5 needs to move along the X-axis, the first driving motor 13 is started to operate. The first driving motor 13 drives the first threaded rod 12 to operate, and the first threaded rod 12 drives the first connecting plate 14, the first mounting bracket 11, and the slider 10 to move along the slide rail 9, so as to drive the engraving head 5 to move along the X-axis. The provided second mounting bracket 24 can mount the engraving head 5, and the mutual cooperation of the electric slide rail 21 and the electric slider 22 can drive the engraving head 5 to move along the Z-axis. Subsequently, the provided second driving cylinder 17 can drive the second threaded rod 16 to rotate, and then drive the second threaded sleeve 19 and the engraving head 5 to move along the Y-axis. The provided limiting rod 18 and the limiting block 20 can limit the engraving head 5, so as to prevent the engraving head 5 from shaking when moving. When there is a lot of waste generated during the engraving process, the driving cylinder 30 is started to operate, and the driving cylinder 30 rises. Then it can push the workbench 6 to tilt up along one side of the connecting frame 1. Then the waste on the workbench 6 can fall through the blanking groove 27. A collection box for collecting waste can be arranged below the blanking groove 27, so as to discharge the waste centrally. When the workbench 6 needs to be tilted up, the adjusting threaded sleeve 36 is rotated to make the two groups of third threaded rods 35 drive the third mounting bracket 32 to move. When the third mounting bracket 32 moves, it can be limited by the second limiting rod 31. Subsequently, the third mounting bracket 32 can drive the positioning rod 34 away from the inside of the workbench 6, facilitating one end of the workbench 6 to tilt up. After the waste is discharged, rotating the adjusting threaded sleeve 36 in the reverse direction can make the positioning rod 34 reinsert into the inside of the workbench 6 for limiting.
