In the utility model, the sliding member includes a slide 5 arranged on the other side of the support frame 2, and a first sliding rod 6 connecting the slide 5. The sliding structure includes a sliding plate 8 arranged on the top of the slider 15, and a second sliding rod 9 connecting the sliding plate 8. The slide rail 16 and the slide 5 are parallel in the horizontal direction, and the length of the slide rail 16 and the slide 5 does not exceed the length of the workbench 1, ensuring that the moving range of the slide rail 16 and the slide 5 does not exceed the range of the workbench 1.

The laser assembly of the utility model comprises: a laser emitter 21 connected to the second electric cylinder 17, and a laser emitter head 22 arranged on the laser emitter 21; the first electric cylinder 7 and the second electric cylinder 17 drive the first slide 6 and the second slide rod 9, thereby driving the sliding of the laser assembly.
