The bottom end of the front surface of the protective cover 31 is fixedly connected to a handle 32, and the inner wall of the bottom end of the handle 32 is slidably connected to an L-shaped block 37.

[0033] Reference Figure 1 - Figure 2 , Figure 4 The collecting assembly 4 includes a rectangular shell 41, which is fixedly connected to the left end of the lower surface of the processing table 2. Through holes are provided on the lower surfaces of the left and right ends of the processing table 2, which are connected to the rectangular shell 41, so as to facilitate the centralized collection of debris and improve practicality. A collecting box 42 is slidably arranged on the inner wall of the rectangular shell 41, and a through groove 44 is provided at the left end of the front surface of the collecting box 42, and a rectangular groove 47 is provided at the front end of the inner wall of the rectangular shell 41.

[0034] Reference Figure 2 - Figure 3 The inner wall of the through groove 25 is elastically connected with a slider 35 through a spring 36. The spring 36 always pulls the slider 35 to move to the right through its own elasticity, thereby ensuring the sealing of the protective cover 31 and improving practicality. The slider 35 is slidably connected to the inner wall of the through groove 25, one end of the spring 36 is fixedly connected to the inner wall of the through groove 25, and the other end of the spring 36 is fixedly connected to the right surface of the slider 35.

[0037] Working principle: When in use, spring 1 36 will always pull the slider 35 through its own elasticity to keep the protective cover 31 in a closed state, ensuring that the grinding debris will not fall on the worker, thereby improving the protection effect. At the same time, the worker can observe the grinding situation through the transparent plate 33, which improves practicality. When the protective cover 31 needs to be opened, it is only necessary to hold the handle 32 to push the protective cover 31, and the protective cover 31 will drive the slider 35 to move, and the slider 35 will stretch the spring 1 36 until the spring 1 36 is fully opened. At this time, the L-shaped block 37 will contact the fixed shell 34, and the fixed shell 34 will move along the L The inclined surface of the L-shaped block 37 pushes it to move upward until the bottom end of the L-shaped block 37 coincides with the inner wall of the fixed shell 34. At this time, the L-shaped block 37 will fall under gravity and insert into the inner wall of the fixed shell 34, so that the protective cover 31 can be limited. When closing, it is only necessary to push the L-shaped block 37 to release the limit on the protective cover 31, and then push the handle 32 to make the L-shaped block 37 and the fixed shell 34 not overlap, and then loosen the handle 32. The spring 1 36 will pull the slider 35 to move in the opposite direction through its own elasticity, and the protective cover 31 will also move in the opposite direction to close, which is quick and convenient, and improves work efficiency.

[0038] The debris generated by grinding will fall into the inner wall of the collection box 42 along the inclined surface set on the inner wall of the processing table 2. When the collection box 42 needs to be taken down and the debris inside it needs to be cleaned, it is only necessary to push the handle 43, and the handle 43 will drive the limit plate 46 to move, and the limit plate 46 will squeeze the spring 2 45 until the limit plate 46 is completely separated from the inner wall of the rectangular groove 47, and the spring 2 45 can be taken out. When installing, the collection box 42 is inserted into the inner wall of the rectangular shell 41 until the limit plate 46 contacts the rectangular shell 41, and the rectangular shell 41 will push it to move along the inclined surface of the limit plate 46, and the limit plate 46 will squeeze the spring 2 45 until the limit plate 46 overlaps with the rectangular groove 47. At this time, the spring 2 45 will push the limit plate 46 to move in the opposite direction through its own elasticity and insert it into the inner wall of the rectangular groove 47 to limit the collection box 42.
