At this time, the staff can directly swing the driving arm 203 downward, the driving arm 203 can be clamped with the shaft sleeve, so that the driving arm 203 can drive the ratchet wheel 206 and the transmission shaft 210, the ratchet wheel 206 rotates clockwise by a certain angle, and the transmission mechanism 3 is driven to transport materials through the transmission shaft 210. When rotating a certain angle, the driving arm 203 is pushed upward, the driving arm 203 rotates along the transmission shaft 210, the ratchet wheel 206 cannot rotate counterclockwise due to the clamping of the backstop mechanism and the first connecting rod 204 with the ratchet teeth of the ratchet wheel 206, and the second gas spring 212 pulls the first connecting rod 204 back to the initial clamping position of the ratchet wheel 206, so that the automatic return purpose is achieved.

[0023] The backstop mechanism comprises a connecting block 201, the connecting block 201 is bolted to the base 1, the connecting block 201 is bolted with a first gas spring 202, the other end of the first gas spring 202 is bolted with a second connecting rod 205, one end of the second connecting rod 205 is movably connected with the base 1, and the other end of the second connecting rod 205 abuts against the ratchet teeth of the ratchet wheel 206. Due to the clamping of the second connecting rod 205 with the ratchet teeth of the ratchet wheel 206, the ratchet wheel 206 cannot rotate counterclockwise, and when the ratchet wheel 206 rotates clockwise by one tooth, the first gas spring 202 constantly pulls the second connecting rod 205 back to the original position.

[0024] One end of the driving arm 203 is connected with a push rod 207, and the push rod 207 is located close to the second gas spring 203. The push rod 207 can more easily drive the driving arm 203 to move, so that rotating the driving arm 203 is not so laborious.
