Preferably, the uppermost edge of the roller is in constant contact with the lowermost edge of the cam. The stamping precision is guaranteed by the arrangement, so that the stamped stamp effect is better.

Preferably, the rolling member is sleeved in a limiting groove of the limiting block, the stamp is fixed below the limiting block, the upper edge of the rolling member is located on the upper side of the upper end face of the limiting block, a limiting ring is fixed on the upper side of the limiting block, the limiting ring is provided with a limiting inner end face located above the curved surface of the rolling member, the limiting inner end face gradually extends towards the circumferential inner side from bottom to top, and the upper edge of the limiting inner end face is located on the circumferential inner side of the inner edge of the limiting groove. The above arrangement enables rolling of the rolling elements so that wear on the rolling elements is more even.

Preferably, the surfaces of the rolling members, which are used for contacting the cam, are all in contact with the groove walls of the limiting grooves, when the rolling members are in a circular plate shape, the limiting grooves can be arranged into arc-shaped grooves, when the rolling members are in a spherical shape, the limiting grooves can be arranged into spherical grooves, and the arrangement is used for limiting the displacement of the rolling members in step so as to ensure the stamping precision.

Preferably, the rolling member is arranged in a limiting groove of the limiting block, the stamp is fixed below the limiting block, a fixing shaft is fixed in the limiting groove, the rolling member is rotatably fixed on the fixing shaft, and the fixing shaft and the rotating output shaft are arranged in parallel. The above arrangement enables rolling of the rolling elements so that wear on the rolling elements is more even.

Preferably, the lowest edge of the rolling piece is in contact with the bottom of the limiting groove. The arrangement is used for preventing the fixing shaft from being bent and broken.

Preferably, a vertically arranged fixing column is connected and fixed between the limiting block and the seal, the support is provided with a support plate located below the cam, the support plate is provided with a sliding groove penetrating through the support plate from top to bottom, and the fixing column is slidably matched in the sliding groove. The arrangement realizes the guiding of the stamp during moving up and down.
