A positioning pin 7 is inserted into the top of the positioning seat 6, and an anti-falling chain 8 is arranged between the positioning pin 7 and the painting tool base 1.

[0025] It should be noted that due to the large margin between the positioning column of the existing laser engraving tooling and the positioning hole of the workpiece, the workpiece is prone to shaking, causing the laser engraving line to deviate too much. In this embodiment, the workpiece can be positioned and clamped by the first workpiece fixing horse 3, the second workpiece fixing horse 4 and the positioning seat 6, thereby ensuring the stability of the workpiece during the laser engraving process and avoiding positional deviation. The problem of workpiece shaking caused by the large margin between the positioning column and the positioning hole of the workpiece in the traditional laser engraving tooling is avoided. By moving the support plate 17 to the empty space between the workpiece and the base 1 of the paint spraying tooling and lifting the workpiece, the workpiece can be effectively supported, avoiding the problem of deformation of the workpiece due to local lack of support, thereby indirectly improving the accuracy of the workpiece after laser engraving.
