The locking block 102 extends into the interior of the active sliding groove 201. The pressing plate 303 is in contact with the locking block 102.

[0025] Working principle: When the sponge grinding plate 1 is severely worn, only need to press the tooth groove knob 3021 to complete the unlocking operation, so that the pressing plate 303 pops out and separates from the locking block 102. Then take out the sponge grinding plate 1 and replace it. Align the locking block 102 on the back of the new sponge grinding plate 1 with the combined slot 202 on the surface of the rubber cushion block 2 and insert it. Then close the pressing plate 303 towards the center to complete the locking, and the fixing operation of the sponge grinding plate 1 and the rubber cushion block 2 can be realized. By the way of quick disassembly and replacement of the single structure of the sponge grinding plate 1, the use cost can be effectively reduced.
