[0041] Compared with the prior art, a pad 33 is provided between the connector 31 and the skeleton back plate 1 so that the print head 32 can approach and tilt relative to the print roller 2, so that the distances between the upper and lower ends of the print head 32 and the print roller 2 are the same, thereby making the pressure applied by the upper end of the print head 32 on the print roller 2 equal to the pressure applied by the lower end of the print head 32 on the print roller 2, thereby improving the printing clarity. This can solve the technical problem in the prior art that the cantilever effect causes the pressure applied by the upper print head 32 on the print roller 2 to be less than the pressure applied by the lower print head 32 on the print roller 2, thereby resulting in unclear printing at the upper end.

[0042] Specifically, in the present device, the printing rubber roller 2 is arranged in a direction perpendicular to the plane where the skeleton back plate 1 is located, and is rotatably connected to the skeleton back plate 1. Friction is provided by rotating relative to the line number tube, so that the line number tube moves relative to the printing rubber roller 2.
