It can be understood that when they are close to each other and abut against each other, the first extrusion frame 301 and the second extrusion frame 302 form an annular extrusion frame.

[0032] A first groove is provided on one side of the first extrusion frame 301 facing the second extrusion frame 302, and a second groove is provided on one side of the second extrusion frame 302 facing the first extrusion frame 301.

The first transmission shaft 431 and the second transmission shaft respectively drive the first transmission plate 311 and the second transmission plate 312 to approach and close together, thereby driving the first extrusion frame 301 and the second extrusion frame 302 to gradually close together from a mutually open and closed state, and close to form a circular ring, which is sleeved outside the cover plate 200 and the opening to complete the sealing of the vacuum coating equipment.
