[0023] In this embodiment: when using this device, by starting the drive motor 3, the operation of the drive motor 3 will drive the first gear 401 connected to the output end to rotate. When the first gear 401 rotates, the tooth blocks distributed 180 degrees on the outer wall contact the second gear 402, giving the second gear 402 and the first rotating rod 403 a rotating force, so that the first rotating rod 403 rotates, and the rotating first rotating rod 403 transmits the rotating force to the conveyor belt 2 to make it transmit, until the first gear 401 is no longer in contact with the second gear 402.
