[0020] The opening of the processing cavity 2 is closed by pulling the two protective doors 4 closer to each other, and at the same time, the protective door 4 is moved to drive the No. 1 rack plate 6 to move horizontally, so that the No. 1 rack plate 6 drives the No. 1 gear 8 to rotate, and the No. 2 gear 9 rotates synchronously with the No. 1 gear 8, thereby driving the movable plate 10 and the No. 2 rack plate 11 to move upward along the inside of the processing cavity 2, so that the rising movable plate 10 protects the closing protective door 4, which reflects the synchronous movement effect of the movable plate 10 with the protective door 4.

[0021] Reference Figure 2 and Figure 3The buffer mechanism includes a fixed groove 12, which is symmetrically arranged at the upper and lower ends of the movable plate 10. Support rods 13 are fixedly installed on both sides of the inner wall of the fixed groove 12. Springs 14 are sleeved on both sides of the outer surface of the support rod 13. A movable part 15 is movably installed on the outer surface of the support rod 13 near the spring 14. A through hole is penetrated in the middle of one side of the movable part 15. The outer diameter of the support rod 13 is smaller than the inner diameter of the through hole. The support rod 13 and the through hole are coupled to each other.
