[0032] As a preferred implementation method, the side blocking assembly 207 includes a side plate 2071. A sliding groove 2072 is provided on the inner wall of the side plate 2071. A limiting sliding plate 2073 is slidably connected to the inner wall of the sliding groove 2072; further, the limiting sliding plate 2073 can slide in the sliding groove 2072 and then be limited.

[0033] As a preferred implementation method, the bottom end of the limiting sliding plate 2073 is fixedly connected to a telescopic plate 2074. The telescopic plate 2074 is movably connected to the inner wall of the side plate 2071; further, the telescopic plate 2074 can move up and down within the side plate 2071.

[0034] As a preferred implementation method, a spring 2075 is fixedly connected to the upper end of the limiting sliding plate 2073. The springs 2075 are evenly installed between the limiting sliding plate 2073 and the inner wall of the side plate 2071; further, the springs 2075 can be evenly stressed to keep the telescopic plate 2074 moving downward all the time.

[0036] As a preferred embodiment, the conveying mechanism 7 includes a motor 701. The output shaft of the motor 701 is connected to a transmission shaft 702 through a coupling. One end of the transmission shaft 702 is fixedly connected to a conveying shaft 703.
