At this time, the first curved plate 31 is subjected to downward pressure, so that the glass is tightly clamped by the first curved plate 31 and the first support ring 12, thereby achieving a sealing effect; at this time, when the glass needs to be disassembled, the second threaded tube 21 is rotated in the direction, and then the entire second threaded tube 21 and the second support ring 22 are removed, and then the second curved plate 41 is moved outward along the first slider 121. Then, the first curved plate 31 and the second curved plate 41 are separated from the glass, and the glass can be quickly removed at this time.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
