The bottom of the threaded rod 9 is fixedly connected with a bearing 11, and the cover plate 2 is fixedly connected to the bearing 11. The rotating disk 10 is lifted by hand to make the crossbeam frame 5 and the cover plate 2 rotate around the first cylinder 4, and the groove 12 slides into the top of the crucible 1, and then the L-shaped buckle block 8 is manually lifted to make the L-shaped buckle block 8 rotate around the second cylinder 7. The L-shaped buckle block 8 has a certain elastic deformation ability, and then the top of one end of the crossbeam frame 5 fits with the bottom of one end of the L-shaped buckle block 8. The rotating disk 10 is further rotated, and the rotating disk 10 drives the threaded rod 9 to rotate downward inside the crossbeam frame 5. Due to the reaction force, the cover plate 2 is tightly pressed against the top of the crucible 1, so that the crucible 1 and the cover plate 2 can be pressed tightly;

[0030] A groove 12 is provided at the bottom of the cover plate 2, and the crucible 1 is slidably connected to the groove 12. The groove 12 allows the crucible 1 and the cover plate 2 to fit more closely and achieve a better sealing effect.

[0031] A slope is provided at the top of one end of the crossbeam frame 5, and a slope is also provided at the bottom of one end of the L-shaped buckle block 8. The setting of the slope makes the contact between the crossbeam frame 5 and the L-shaped buckle block 8 more firm, so that the crossbeam frame 5 and the L-shaped buckle block 8 will not slip off and affect the sealing after being subjected to force.
