Two limiting mechanisms 8 are provided at both ends of the cover, so that the two ends of the cover decorative paper can be folded. The electric push rod 802 pushes the abutment plate 801, and the roller 804 fits the outer wall of the cover. The elastic block 803 shrinks elastically and the roller 804 rolls, thereby moving and pressing the corresponding decorative paper at both ends of the cover.
