After the crucible 3 enters part of the enclosed space, the situation that the crucible 3 tilts and falls due to the absence of the limiting block 2 at the notch 1013 is avoided.

[0034] In one embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , at least two notches 1013 are arranged at equal radii with the center point of the support plate 101 as the center to realize the supporting effect of the crucible 3 in different directions.

The sliding rod 102 passes through the through hole. By providing the fixed plate 105, the sliding rod 102 drives the support plate 101 to slide along the height direction along the through hole, and when in the limiting state, the second surface 1015 is in surface contact with the blocking portion 205, so that the blocking portion 205 blocks the support plate 101.
