Box opening slow action mechanism of thermal printer

The utility model discloses a box opening slow motion mechanism of a thermal printer, which comprises a first shell and a second shell which are hinged with each other, the first shell is provided with a damping piece, the second shell is provided with a damping groove, the damping groove is provided with damping grease, the damping piece is rotatably assembled in the damping groove, and the damping grease is arranged in the damping groove. And the circumferential rotation of the damping piece is limited by the damping grease in the damping groove, so that damping is formed for the rotation between the first shell and the second shell, damping is formed in the rotation process between the first shell and the second shell, and the covering speed is limited. Therefore, it is guaranteed that the covering action between the first shell and the second shell is slow, the hand of a user is prevented from being hit, and the good man-machine experience feeling is guaranteed. 本实用新型公开了一种热敏打印机的开盒缓动机构，包括相铰接的第一壳体和第二壳体，所述第一
