[0026] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 6 As shown, an embedded printer that is easy to assemble and disassemble in the embodiment of the first aspect of the present invention includes a body 1, a connecting ear 2 and a spring 3. The connecting ears 2 are respectively provided on both sides of the body 1;

[0029] The connecting ear 2 is hinged to the body 1, and a clamping block is provided at the bottom end of the connecting ear 2. The clamping block is arranged on the side of the connecting ear 2 facing the body 1. The clamping block is used to limit the rotation range of the connecting ear 2. When the connecting ear 2 rotates to a certain range, the clamping block abuts against the body 1, thereby limiting the connecting ear 2 from continuing to rotate.

[0030] A spring 3 is provided between the connecting ear 2 and the body 1 , with both ends of the spring 3 respectively contacting the body 1 and the connecting ear 2 . The axis of the spring 3 is perpendicular to the rotating shaft of the connecting ear 2 . The spring 3 is always in a compressed state during use.

[0031] In this embodiment, it should be noted that the internal structure of the body is the same as that of the existing micro embedded printer, which will not be described in detail. The present invention is mainly aimed at improving the body structure of the printer; the card block and the connecting ear 2 are an integrated structure, such as Figure 6As shown, the bottom of the block is provided with an inclined surface 10. When the connecting ear 2 is rotated to the maximum extent, the inclined surface 10 abuts against the body 1.

[0032] Before installation, the connecting ears 2 are in the open state. When the fuselage 1 is pushed into the panel groove 13 on the installation panel 12, the connecting ears 2 on both sides of the fuselage 1 are compressed inward until they are installed in the panel groove 13. Under the action of the spring 3, the connecting ears 2 are pressed against the edge of the panel groove 13 to achieve a fixing effect.

[0033] The technical effect achieved by this embodiment is: during installation, after the fuselage 1 is inserted into the panel slot 13 on the installation panel 12, the connecting ears 2 on both sides of the fuselage 1 can be tightly engaged with the edges of the panel slot 13 under the action of the spring 3, thereby clamping the fuselage 1 in the panel slot 13, eliminating the need for screws and the time required to install the screws, and quick disassembly and assembly can be achieved.

By setting the receiving groove 4, the connecting ear 2 is embedded after assembly, and the overall structure is more regular, so that the fuselage 1 can be installed more tightly in the panel groove 13.

[0037] In this embodiment, it should be noted that a rotating shaft 8 is provided on both sides of the connecting ear 2. The rotating shaft 8 and the connecting ear 2 are an integral structure. The rotating shaft 8 is cylindrical and is rotatably connected to the side wall of the accommodating groove 4.

[0038] Furthermore, a mounting groove 6 is provided on the side wall of the receiving groove 4, and the mounting groove 6 extends from the outside of the receiving groove 4 to the inside of the receiving groove 4. A groove 7 is provided in the mounting groove 6, and a rotating shaft 8 is rotatably disposed in the groove 7;

[0039] The width of the head portion of the installation groove 6 is greater than the width of the tail portion. During assembly, it is convenient to slide the shaft 8 along the installation groove 6 and insert the shaft 8 into the groove 7 .

[0041] like Figures 1 to 6 As shown, this embodiment provides another embedded printer that is easy to assemble and disassemble. Its structure includes all the contents of embodiment 1, and only the different parts are described below.

[0042] In this embodiment, a first positioning post 5 is provided on the side of the connecting ear 2 facing the fuselage 1, and a second positioning post 9 is provided on the side of the fuselage 1 facing the connecting ear 2. The two ends of the spring 3 are respectively mounted on the first positioning post 5 and the second positioning post 9.

[0043] In this embodiment, it should be noted that the first positioning column 5 and the connecting ear 2 are an integral structure, the first positioning column 5 is perpendicular to the rotating shaft 8 , and the second positioning column 9 and the body 1 are an integral structure.

[0044] The technical effect achieved by this embodiment is that by providing the first positioning column 5 and the second positioning column 9, it is possible to facilitate the positioning and installation of the spring 3 and prevent the spring 3 from shifting during use.

[0045] Example 4

[0046] like Figures 1 to 6 As shown, this embodiment provides another embedded printer that is easy to assemble and disassemble. Its structure includes all the contents of embodiment 1, and only the different parts are described below.

[0047] In this embodiment, a plurality of steps 11 are provided on the top of the connecting ear 2 . The steps 11 are provided on the side of the connecting ear 2 facing away from the body 1 . The plurality of steps 11 are sequentially provided along the height direction of the connecting ear 2 .

[0048] In this embodiment, it should be noted that the number of steps 11 can be set to two, three, four or five, etc.

[0049] The technical effect achieved by this embodiment is that by providing a plurality of steps 11, it is applicable to a plurality of mounting panels 12 of different thicknesses, so that after installation, the surface of the mounting panel 12 can be closely fitted with the edge of the fuselage 1 (e.g. Figure 3 shown).
