In this embodiment, starting the driving motor 61 drives the driving gear 62 at the output end to rotate. Since one side of the driving gear 62 is meshed with the side of the gear rod 5 with the toothed portion, one side of the gear rod 5 is driven. The movement of the gear rod 5 will drive multiple driven gears 4 and the sealing blade 3 to rotate.

[0024] It also includes a support base 8, which is fixedly installed at the bottom of the driving motor 61, and one side of the support base 8 is fixedly installed on one side of the mounting frame 1 by bolts.
