[0042] Example 2:
[0043] Based on the above embodiment 1, in order to improve the stability of the movable plate 5 when it moves, it is necessary to guide the movable plate 5, so the following structure will be set.
[0044] See Figures 1-3 Four sliding rods 8 are connected between the top plate 3 and the bottom plate 1.

[0045] The working principle of this utility model is as follows: First, when using it, the power is turned on. Then, the operator puts a tempered glass into the top of the heating box 10, and then puts in the PVB interlayer. Next, another tempered glass is placed on top of the PVB interlayer. Then, the first motor 906 is started. The first motor 906 drives the gear 905 to rotate. The gear 905 drives the two racks 903 to move simultaneously.
