The two groups of square sliders 5 drive the connecting rod 6, and the connecting rod 6 drives the clamping frame 7 to move from both ends to the middle. Due to the rounded design of one corner of the L-shaped plate 8, it is convenient to guide the ceramic flat membrane into the cleaning box 1. In the clamping groove 12, when the L-shaped plate 8 contacts the ceramic flat membrane, the spring 9 is compressed under the action of pressure, and the ceramic flat membrane can enter the clamping groove 12 and contact the side wall of the clamping groove 12.
