[0025] The driving gear 302 is driven by a built-in motor, and the driving box 301 is provided with a U-shaped opening, and the rotating rod 305 passes through the U-shaped opening and extends to the outside of the driving box 301 .

[0026] By setting up the driving structure 3, the active gear 302 inside the driving box 301 can drive the two follower gears 304 to rotate through the passive gear 303, so that the two follower gears 304 drive the two spliced ​​cover plates 2 to gradually separate through the rotating rod 305, thereby realizing the function of automatic opening and closing of the feed port.
