The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, which shows an overall schematic diagram of a printer according to an embodiment of the present invention, the printer includes a main body 11, and an upper shell 12 and a lower shell 13 respectively covering two sides of the main body, the lower shell 13 is used as a supporting portion of the printer, and a printing paper of the printer is delivered from a paper outlet on the upper shell 12 after being printed.

The main body 11 is provided with a printing assembly capable of realizing a complete printing function, a paper box assembly and a battery assembly to be replaced are respectively positioned on different sides of the main body 11, the upper shell 12 is positioned on one side of the main body 11 where the paper box assembly is installed, and the lower shell 13 is positioned on one side of the main body 11 where the battery assembly is installed.

The upper casing 12 and the lower casing 13 can both rotate relative to one side of the main body 11, that is, the upper casing 12 and the lower casing 13 respectively have one end hinged with the main body 11 to realize the opening and closing of two sides of the printer.

Referring to fig. 2, which shows an opening schematic diagram of the printer according to an embodiment of the present invention, at this time, one end of the upper case 12 is separated from the main body 11, one end of the lower case 13 is also separated from the main body 11, and the movements of the upper case 12 and the lower case 13 are not affected by each other.

In an embodiment of the present invention, the connection mode of the upper shell 12 and the main body 11 is a snap connection, the connection mode of the lower shell 13 and the main body 11 is the same as the connection mode of the upper shell 12 and the main body 11, the upper shell 12 is detachably connected with the main body 11 through the elastic member 121, and the lower shell 13 is detachably connected with the main body 11 through the elastic member 131.

Referring to fig. 3, which is a top view of the printer according to an embodiment of the present invention, a detailed manner in which the upper case 12 and the lower case 13 are respectively connected to the main body 11 will be described with reference to fig. 4. Fig. 4 is a sectional view taken along a-a of fig. 3, in which the upper case 12 is extended with the elastic member 121 toward the main body 11, and the lower case 12 is extended with the elastic member 131 toward the main body 11.

A stopper 111 corresponding to the upper case and a stopper 112 corresponding to the lower case are fixed to the body 11, and the elastic member 121 and the stopper 111 are connected in the same manner as the elastic member 131 and the stopper 112, and the connection of the elastic member 121 and the stopper 111 will be described below as an example.

The free end of the elastic element 121 protrudes laterally to form a protrusion, when the upper case 12 is in a closed state (i.e., the state shown in fig. 4), the protrusion abuts against the stopper 111, and the elastic element 121 is limited to be separated from the stopper 111 under an unstressed condition, i.e., the closed state of the upper case 12 and the main body 11 is maintained.
