[0038] It should be noted that when cleaning the PCB board, the PCB board needs to be vertically inserted into the placement groove 309 provided on the fixing clamp 308 to fix the PCB board to prevent the PCB board from shaking during cleaning.

[0039] Specifically, the clamping motor 301 is fixedly connected to the fixed plate 310 through the support plate, the worm 302 is rotatably connected to the fixed plate 310 through the support plate, the end of the worm 302 away from the clamping motor 301 is engaged with a worm gear 303, the bidirectional threaded rod 304 is rotatably connected to the fixed plate 310, and two groups of threaded blocks 305 are symmetrically provided, and both groups of threaded blocks 305 are threadedly connected to the bidirectional threaded rod 304, one side of the threaded block 305 is fixedly connected to a slider 306, and the slider 306 is slidably connected to the slide groove 307 provided on the fixed plate 310.
