[0056] Adopting the above scheme: rotate the threaded rod 432, the threaded rod 432 can drive the transmission block 431 to slide along the inner wall of the sliding groove 433, and the transmission block 431 can drive the shovel block 410 to move forward through the support rod 420 and remove the residual impurities on the upper surface of the working platform 3.

[0057] Reference Figure 2 As shown in the figure, the driving assembly 440 includes:

[0058] The pulley 441 is provided with two, and the two pulleys 441 are connected by a belt transmission. The pulley 441 is fixedly connected to the outer surface of the threaded rod 432.
