[0003] A Chinese public patent (publication number: CN 212211527 U) discloses an etching fixture for the production of integrated optoelectronic devices, which includes a base, the bottom of which is welded with support legs, the number of which is four groups and arranged in a rectangular array at the bottom of the base, a rubber patch is provided at the bottom of the support legs, the top of the base is welded with support rods, the number of which is four groups and arranged in a rectangular array, a workbench is welded on the top of the support rods, and a pneumatic chamber is embedded on the top of the workbench. In this device, a suction cup is used to fix the circuit board, so that to a certain extent, the damage to the circuit board caused by excessive pressure is effectively avoided. At the same time, the use of the suction cup also makes the device lighter and faster when replacing the circuit board at work;

[0004] Although the above patent can fix the electronic device by using a suction cup, the above patent uses a carving knife to perform etching, but there are still certain defects.

[0033] In one embodiment, a cleaning device 5 is provided in the inner cavity of the shell 1, and the cleaning device 5 includes a waste hole 501, which is opened at the middle end of the bottom of the inner cavity of the shell 1. A DC motor 502 is fixedly connected to the right side of the shell 1, and a threaded rod 503 is fixedly connected to the output end of the DC motor 502. The outer surface of the threaded rod 503 is threadedly connected to a threaded sleeve 504, and the bottom of the threaded sleeve 504 is fixedly connected to a fixed rod 505. The front side of the fixed rod 505 is fixedly connected to a scraper 506, and the bottom of the support leg 3 is fixedly connected to a bottom plate 507, and a pull-out box 508 is provided on the top of the bottom plate 507.
