Further, a bracket is arranged at the inner bottom of the turnover cover, and the rotating piece is installed on the side panel of the bracket through a rotating shaft.
Further, the rear end of rotating member has the trompil on the side panel of support, be located the rear of rotating member is equipped with the notch rotating member the trompil with on the side panel of support install the extension spring between the notch, the one end of extension spring is colluded rotating member on the trompil, the other end of extension spring is colluded on the side panel of support on the notch.
Further, the rotating part includes rotatory briquetting and set up in the push pedal in the place ahead on the rotatory briquetting, the pivot set up in on the rotatory briquetting.
Further, the lower end of the rotating pressing block is provided with an arc-shaped convex part, and when the front end of the pushing plate tilts upwards, the arc-shaped convex part at the lower end of the rotating pressing block presses the cover opening pressing plate at the front end of the middle frame.
Adopt the utility model provides a thermal printer with mechanism of uncapping utilizes lever principle, and when the front end of rotating member was upwarped, the rear end below of rotating member was pressed on the clamp plate of uncapping of the front end of center, and flip and center form the opposite face of lever board, easily open flip. And install the extension spring between the trompil of rotating member and the notch on the side board of support, after uncapping, the rotating member resets through the pulling effect of extension spring, and the operation is sensitive, need not artifical the resetting.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1 to 6, the embodiment of the present invention provides a thermal printer with a cover opening mechanism, including a middle frame 1 and a flip 2 disposed above the middle frame 1, the flip 2 is rotatably mounted on the middle frame 1, a rotating member 3 is disposed on one side of the front end of the flip 2, a cover opening pressing plate 4 is disposed on one side of the front end of the middle frame 1 corresponding to the position of the rotating member 3, and when the front end of the rotating member 3 tilts upward, the lower part of the rear end of the rotating member 3 presses on the cover opening pressing plate 4 of the front end of the middle frame 1.
Adopt the embodiment of the utility model provides a thermal printer with mechanism of uncapping utilizes lever principle, and when the front end of rotating member 3 perk up, the rear end below of rotating member 3 was pressed on the clamp plate 4 that uncaps of the front end of center 1, and flip 2 and center 1 form the opposite face of lever board, easily open flip 2.
Specifically, a bracket 5 is provided at the inner bottom of the folder 2, and the rotary member 3 is mounted on the side panel of the bracket 5 by a rotary shaft 6.
Preferably, the rear end of the rotary member 3 has an opening 7, a notch 8 is provided on the side panel of the bracket 5 at the rear of the rotary member 3, a tension spring 9 is installed between the opening 7 of the rotary member 3 and the notch 8 on the side panel of the bracket 5, one end of the tension spring 9 is hooked on the opening 7 of the rotary member 3, and the other end of the tension spring 9 is hooked on the notch 8 on the side panel of the bracket 5. Because the rotating part 3 is connected to the side panel of the bracket 5 through the tension spring 9, after the cover is opened, the rotating part 3 is reset through the pulling action of the tension spring 9, the operation is sensitive, and manual reset is not needed.
