s3, when the hot melt box (1) is carried, after the supporting seat (13) is in contact with the ground, the supporting rod (12) drives the circular plate (14) to slide downwards along the inner surface of the supporting seat (13), meanwhile, the circular plate (14) begins to extrude the compression spring (15), and through the elastic potential energy of the spring (15), the damping and buffering of the hot melt box (1) are realized, the rigid collision between the supporting seat (13) and the ground is avoided, and the supporting seat (13) and the ground are further prevented from being damaged.
10. The quartz-fed lossless addition method for transversely stacking polycrystalline silicon feedstock as claimed in claim 9, wherein: the circular plate (14) is matched with the supporting seat (13) in size, and the fixing column (33) is matched with the sliding groove (36) in size.
