[0025] Embodiment 2

[0026] Based on Example 1, please refer to the attached Figure 1 The U-shaped baffle plate 2 has blocks 12 fixedly connected on both sides thereof to cooperate with the protective top plate 3 and the protective side plate 4. After the protective side plate 4 is flipped upward and closed, one side of the block 12 abuts against the inner wall of the protective side plate 4. After the protective top plate 3 is flipped downward and closed, the upper end of the block 12 abuts against the inner wall of the protective top plate 3 to prevent the protective top plate 3 and the protective side plate 4 from flipping over excessively.

[0027] In specific use, before processing, the protective side panels 4 are flipped upwards, and the adjustment blocks 9 on both sides are pushed to slide into the lock slots 6 to squeeze the fixed springs 8 to cause compression deformation. After the protective side panels 4 are against one side of the block 12, the adjustment blocks 9 are loosened, and the locking tongues 7 on both sides are inserted into the fixed slots 11 on both sides under the restoring elastic force of the fixed springs 8 to fix the protective side panels 4.

The processing status of the parts can be observed through the observation window 5. The rocker 14 is shaken to drive the cleaning scraper 13 to swing, so as to clean the inside of the observation window 5 to prevent the observation window 5 from being polluted and blocking the line of sight. The rocker 14 rotates to drive the gear to rotate, and the gear drives the rack 18 to slide along the slide bar 17, squeezing the reset spring 19 to cause compression deformation. After the rocker 14 is released, the rack 18 is pushed to slide in the opposite direction under the restoring elastic force of the reset spring 19, and the rack 18 drives the gear to drive the rocker 14 to rotate in the opposite direction, so that the scraper scrapes in the opposite direction, and the observation window 5 is cleaned again.
