Both sides of the rotating rod 1 are fixedly connected with a ring 11. Both sides of the top of the disc 2 are fixedly connected with an auxiliary rod 12, and the top of the auxiliary rod 12 is fixedly connected with a magnet 13. By arranging the iron block 10 and the magnet 13, the stability of the disc 2 during disassembly and assembly can be improved, which is conducive to improving the convenience of replacing the sealing mechanism.

[0022] See also Figure 1 and Figure 4 The auxiliary mechanism 6 includes a frame 14, which is located in the inner cavity of the cylinder 4. A second sealing gasket 15 is bonded to the inner cavity of the frame 14. A first bolt body 16 is penetrated on both sides of the cylinder 4. By arranging the frame 14, the second sealing gasket 15 and the first bolt body 16, the sealing effect of the device can be improved, which is beneficial for the operator to use the vacuum coating machine.

[0023] See also Figure 1 A second sealing ring 17 is bonded to the surface of the rotating rod 1. By arranging the first sealing ring 8 and the first sealing gasket 7, the sealing effect can be further improved, thereby bringing convenience to the operator. The top of the first sealing ring 8 is fixedly connected to the disc 2.

[0024] See also Figure 1 and Figure 2 The cylinder 4 is movably sleeved on the surface of the rotating rod 1.
