The pushing assembly 4 also includes a second ratchet 409, and the second ratchet 409 is fixedly connected to the rear end of the rotating shaft 401. A pawl 410 is engaged above the second ratchet 409, and the pawl 410 is rotatably connected to a support plate 411 on the front. The support plate 411 is fixedly connected to the top of the conveying frame 1, and the bottom of the conveying frame 1 is fixedly connected to a support leg 5, and the number of support legs 5 is four.

[0024] When the above-mentioned device is used, the fireworks paper tubes to be filled with raw materials are placed on the conveyor belt device 3 in sequence, and then the electric push rod 407 is started to reciprocate and retract. The electric push rod 407 retracts to the right to drive the top plate 408 to make the pull bar 405 slide to the right.
