Rack 12 is slidably connected to lower heating plate 3 and meshes with gear 14.

[0029] Align the T-shaped strip 9 with the T-slot 8, move the lower heating plate 3, and let the lower heating plate 3 drive the T-shaped strip 9 to slide inside the T-slot 8. Align the second pin hole 10 with the first pin hole 6, and then insert the pin 7. The pin 7 moves through the first pin hole 6 to the inside of the second pin hole 10, and the pin 7 fixes and limits the T-shaped strip 9 and the base 4, thereby quickly installing the lower heating plate 3 onto the base 4. When disassembly is required, repeat the above operation in reverse to quickly remove it.
