An adjustable bearing assembly 3 is arranged above the base 1, and an etching disk 4 is placed on the adjustable bearing assembly 3. A liquid collecting drawer 5 is slidably connected in the base 1 for collecting the cleaning waste liquid of cleaning the etching disk 4.

[0026] The two-way screw rod 31 is fixedly connected to the groove 2, and the two-way screw rod 31 is threadedly connected to the thread block 32. The upper side of the thread block 32 is fixedly connected to a bearing bar 33. A placement groove 331 is provided on the upper side of the bearing bar 33. The end of the bearing bar 33 away from the thread block 32 is fixedly connected to a guide block 35. The guide block 35 is penetrated by a guide rod 36 and is slidably connected to the guide rod 36. A stabilizing component 34 is provided on the bearing bar 33. By rotating the rotating handle, the two-way screw rod 31 is rotated, driving the thread block 32 to slide, and then driving the two groups of bearing bars 33 to approach each other. After the two groups of bearing bars 33 are close, the etching disk 4 is placed on the placement groove 331 to achieve the placement of etching disks 4 of different sizes.

[0027] Further, in order to ensure the stable bearing of etching disks 4 of different sizes, specifically, the stabilizing assembly 34 includes a pressure rod 341, the pressure rod 341 penetrates the bearing bar 33 and is slidably connected to the bearing bar 33, the end of the pressure rod 341 away from the bearing bar 33 is fixedly connected to a fixing ring 342, the fixing ring 342 is elastically connected to the outer wall of the bearing bar 33 through a return spring 343, a hinge rod 344 is hinged on the outer wall of the fixing ring 342, and a stabilizing rod 345 is hinged on the end of the hinge rod 344 away from the fixing ring 342, the stabilizing rod 345 is penetrated by a positioning shaft 346, and the stabilizing rod 345 and the positioning shaft 346 are connected.

After the two groups of supporting bars 33 are close to each other, place the etching disk 4 on the placement groove 331, and continue to turn the handle to make the supporting bars 33 continue to approach each other. At this time, the etching disk 4 squeezes the pressure rod 341, the reset spring 343 is stretched, and the fixing ring 342 drives the hinge rod 344 to move, thereby making the stabilizing rod 345 rotate around the positioning axis 346, squeezing the etching disk 4 to achieve stability of the etching disk 4, and then the etching disk 4 can be cleaned, and the cleaning waste liquid can slide from the collection tank 101 to the liquid collection drawer 5.
