[0028] Specifically, rotating the adjustment handle 103 can drive the first threaded rod 102 to rotate, and then control the first folding plate 502 and the second folding plate 507 to move in the telescopic plate groove 104 respectively, so that the inner rod 401 and the semicircular sleeve 403 can move relative to each other, and then adjust the length of the inner rod 401 and the semicircular sleeve 403. Under the action of the second spring 701, the spring fixing plate 702 can be pulled, and then the sliding rod 703 and the arc plate 704 are pulled, so that the arc plate 704 is against the inner rod 401 or the semicircular sleeve 403, so that the slider 6 is tightly fitted on the side plate 101, the first folding plate 502, the rotating plate 504, the mounting plate 505 and the second folding plate 507.

[0032] In addition, when the second motor 906 is turned on, the output shaft of the second motor 906 rotates to drive the moving wheel 907 to rotate, thereby driving the laser cutter 10 to move, so as to achieve mobile cutting operation.

[0033] Example 2, continue to refer to Figure 1-Figure 2 In the embodiment of the present invention, the lifting leg mechanism 2 comprises a threaded sleeve 201 rotatably connected to the side plate 101, the threaded sleeve 201 is internally threadedly connected to the threaded leg 202, and the bottom of the threaded leg 202 is fixedly connected to the support block 203.

[0035] During the implementation of the present invention, the side bottom plate 1 is first placed at the specified position. At this time, the side bottom plate 1 and the folding and telescopic base mechanism 5 are adjusted to a horizontal state through the lifting leg mechanism 2. At this time, the side bottom plate 1 is adjusted, so as to adjust the relative position of the side bottom plate 1 and the folding and telescopic base mechanism 5, so as to adjust the length of the telescopic folding rod mechanism 4.

The equipment can be folded and stored through the telescopic folding rod mechanism 4 and the folding and telescopic base mechanism 5. The laser cutter 10 can be driven to move by rotating the positioning rod mechanism 8 and the moving wheel mechanism 9, thereby performing cutting processing on different positions of the ship, thereby improving the efficiency of ship maintenance and cutting.
