[0023] In the embodiment, when the material belt 211 drives the capacitive element 212 to stop shearing, the second air cylinder 241 pushes the positioning rod 242 into the positioning groove 222 and inserts into the positioning clamping groove 2111, at the same time, the third air cylinder 245 pushes the second connecting seat 246 into the positioning conveying groove 223, and the positioning pull rod 247 also inserts into the positioning clamping groove 2111, thereby further limiting the material belt 211, when the shearing is finished, the second air cylinder 241 drives the positioning rod 242 to move back, the guide wheel set 213 rotates, the fourth air cylinder 248 drives the sliding seat 244 to move transversely, and the sliding seat 244 drives the positioning pull rod 247 to pull the material belt 211, thereby realizing stable fixed-point conveying of the material belt 211, so that the next capacitive element 212 moves to the cutting position, thereby improving the stability of conveying, then the third air cylinder 245 drives the positioning pull rod 247 to move back, and then the fourth air cylinder 248 pushes the sliding seat 244 to move to the original position, thereby facilitating the next use.
