[0026] The side pull plate 7 is pulled outward under the action of the elastic potential energy of the reset spring 3, and the limit plug 9 is driven to move outward. After the multiple groups of screening slots 1 are stacked, the side pull plate 7 is loosened, so that the multiple groups of screening slots 1 with different screen hole diameters are spliced ​​and installed under the action of the elastic reaction force of the reset spring 3. This can ensure that the stabilizer raw materials are screened and selected at one time according to the use environment, effectively avoiding the operating steps of screening one by one required by traditional devices, and ensuring the screening efficiency.

The Y-shaped slots 11 are symmetrically opened on both sides of the bottom of another screening slot 1, and the outer side walls of the plug-in rods 10 are plugged with limited plug blocks 9.

[0028] During the stacking process of the multiple groups of screening slots 1, the plugging action of the plugging rods 10 and the Y-shaped slots 11 can initially stabilize the stacking, thereby ensuring the working efficiency of the device during use.

[0029] like Figure 2 As shown, a protective pad 8 is glued to the middle of the inner wall of the side pull plate 7, and the inner side of the protective pad 8 is in contact with the outer wall of the screening tank 1.

[0030] Under the protective effect of the protective pad 8, the inner wall of the side pull plate 7 and the outer wall of the screening tank 1 are buffered and protected, thereby ensuring the integrity of the device during use.
