The stamping wheel 201 is in sliding fit with the stamping shaft 200 along the axial direction, and the two are in circumferential limiting fit to prevent relative circumferential rotation between them. Specifically, the stamping shaft 200 is a D-shaped hole shaft, and the shape and size of the shaft hole of the stamping wheel 201 match it. The stamping wheel 201 and the first roller 203 clamp the paper together to convey the paper, and the stamping wheel 201 stamps on the paper. There are two paper pressing wheels 202, which are respectively arranged at both ends of the stamping shaft 200.
