[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0013] See attached diagram. Figures 1 to 2 The laser perforation and cutting device in this embodiment includes a base 1, a frame 2 on the base 1, a drive mechanism on the frame 2, and a laser head 5 at the output end of the drive mechanism; a support plate 6 on the base 1, a support disk 7 movably mounted on the support plate 6, and several sets of limiting components arranged in a circular array on the support disk 7; a dust collection device 9 on one side of the frame 2, a dust collection pipe 90 at the output end of the dust collection device 9, and a suction head at the end of the dust collection pipe 90.

[0014] Furthermore, the limiting component includes a slide block 8 fixedly connected to the support plate 6, a slide groove 80 on the slide block 8, a slider 81 slidably disposed in the slide groove 80, a limiting block 83 fixedly disposed at the front end of the slider 81, and a connecting arm 82 rotatably mounted on the slider 81, the other end of the connecting arm 82 being rotatably connected to the support plate 7.

[0015] Furthermore, one end of the slider 81 in a set of limiting components is provided with a cylinder 84, and a fixing plate 85 is provided on the base 1, with the cylinder 84 and the fixing plate 85 fixedly connected.
