Another object of the utility model is to provide a simple structure, easily batch production wide application's button printer structure of uncapping.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a button type printer structure of uncapping, is located the printer epitheca and is used for opening with the printer inferior valve and close with the lid, includes universal driving shaft, discount, and the discount passes through discount upper portion to be fixed universal driving shaft both ends still include the button structure, and the button structure includes the button, button and universal driving shaft fixed connection. The middle part of the fastening head is provided with a rotating part which is rotationally connected with the upper shell of the printer. The cover opening structure further comprises a reset tension spring and a fixing portion, one end of the reset tension spring is fastened on the linkage shaft, the other end of the reset tension spring is fixed on the fixing portion, and the fixing portion is fixedly connected to the inside of the upper shell of the printer. By pressing the button, the button slides to push the linkage shaft to move in the same direction, the upper part of the buckle moves in the same direction along with the linkage shaft, the middle part of the buckle rotates when the linkage shaft moves, the upper part of the buckle moves in the same direction along with the linkage shaft to drive the lower part of the buckle to move in the opposite direction, the buckle is separated from the lower shell of the printer, and the printer is opened. When the linkage shaft moves along with the sliding of the button, the reset tension spring connected with the linkage shaft and the fixed part stretches and stretches, and when the pressure of the button is eliminated, the reset tension spring pulls the linkage shaft to reset together with the rebound tension force.

Further, the button structure also comprises a button shell, and the button is embedded in the button shell and protects the button.

Furthermore, an extension spring is arranged in the button shell, and when the pressure on the button is eliminated, the extension spring can enable the button to be quickly restored to the original position.

Furthermore, two reset tension springs are arranged and are respectively positioned at two ends of the button structure and are distributed in a bilateral symmetry mode. The tension is uniform, and the linkage shaft can be rapidly reset.

Furthermore, a groove is formed in the linkage shaft, and one end of the reset tension spring is buckled in the groove. The position of the reset tension spring on the linkage shaft is ensured to be fixed, and the linkage shaft is accurately reset after moving every time.

Furthermore, the buckle head protrudes out of the bottom surface of the upper shell of the printer; the lower printer shell and the corresponding position of the buckle head are provided with clamping grooves, and when the cover is closed, the buckle head is buckled with the clamping grooves, so that the cover of the printer is closed.

The utility model has the advantages that: compared with the prior art, the utility model discloses utilize simple mechanical structure, realize through the button that the printer cover opens and shuts, the singlehanded is pressed and is operated, presses laborsaving, and easy operation is convenient.
