[0014] By adopting the above technical solution, the electric motor can drive the corresponding roller shaft and the rubber roller body to rotate, and the rubber roller body can drive the printing paper to move toward the paper outlet.

[0015] The utility model is further configured as follows: the back clip includes a shell and a clamping body, the shell is divided into a main shell and a back clip cover, a plurality of mounting holes are opened on the four corners of the main shell and the back clip cover, the main shell and the back clip cover are connected by a plurality of bolts through the mounting holes, the clamping body is arranged on both sides of the shell, a guide groove is opened inside the shell along the clamping direction, a locking piece is provided on the shell, and the end of the locking piece can be connected to the clamping body.

[0016] The utility model is further configured as follows: a part of the clamping body is installed in the guide groove, a fixing column is fixedly connected to the guide groove, a mounting block is installed on the clamping body, the mounting block is L-shaped, and a spring is fixedly installed between the mounting block and the fixing column.

[0017] By adopting the above technical solution, through the combination of the clamping body and the spring, the mobile phone can be clamped according to the size of the mobile phone. After the mobile phone is clamped by the clamping body, the clamping body can be locked by pushing the locking piece in to maintain the clamping force on the mobile phone and prevent the clamping body from loosening.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model combines the printer with the back clip, and the printer can be fixed on the back of the mobile phone through the back clip, so that the mobile phone can be better held, and it is convenient to control the taken photos through the app, print the taken photos, and share them with friends.

[0039] Reference Figure 1-5 A universal back-clip printer includes a printer body 1, a paper storage bin 3, a paper feeding mechanism 4, a printing component 5, a back clip 6, and a paper outlet 12. The printer body 1 is provided with a paper storage bin 3, a paper feeding mechanism 4, a printing component 5, a back clip 6, and a paper outlet 12. The printer body 1 is provided with a paper storage bin 3, a paper feeding mechanism 4, a printing component 5, a back clip 6, and a paper outlet 11.

[0040] like Figure 1 and Figure 2 As shown, the printer body 1 includes a shell 2, which is divided into an upper shell 201 and a lower shell 202. The upper shell 201 and the lower shell 202 are hinged by hinges. A paper bin 3 is arranged inside the shell 2, and a paper outlet 12 is provided with serrations 1201. A power button 7, a charging port 8 and a display light 9 are arranged at the upper end of the shell 2. The power button 7, the charging port 8 and the display light 9 are parallel to each other. A shutter button 10 is arranged on one side of the shell 2.

[0041] like Figure 2 and Figure 3 As shown, the paper feeding mechanism 4 includes a roller shaft 402 located inside the printer body 1 . The roller shaft 402 runs through the inside of the rubber roller body 401 . The input shaft of the roller shaft 402 is connected to an electric motor 403 .

[0042] like Figure 1 , Figure 4 and Figure 5As shown, the back clip 6 includes a back clip shell 601 and a clamping body 602. The back clip shell 601 is divided into a main shell 6011 and a back clip cover 6012. A number of mounting holes are opened on the four corners of the main shell 6011 and the back clip cover 6012. The main shell 6011 and the back clip cover 6012 are connected by a number of bolts through the mounting holes. The clamping body 602 is arranged on both sides of the back clip shell 601. A guide groove 603 is opened inside the back clip shell 601 along the clamping direction. A locking piece 604 is provided on the back clip shell 601. The end of the locking piece 604 can be connected to the clamping body 602. A part of the clamping body 602 is installed in the guide groove 603. A fixing column 6031 is fixedly connected to the guide groove 603. A mounting block 6021 is installed on the clamping body 602. The mounting block 6021 is L-shaped. A spring 6022 is fixedly installed between the mounting block 6021 and the fixing column 6031.

[0043] Working principle: In the present invention, firstly, the clamping body 602 and the spring 6022 can be combined to adjust the size of the mobile phone to clamp the mobile phone. After the mobile phone is clamped by the clamping body 602, the locking member 604 can be pushed in to lock the clamping body 602 to maintain the clamping force on the mobile phone and prevent the clamping body 602 from loosening.

[0044] Secondly, open the upper shell 201, put the printing paper in the paper storage bin 3, close the upper shell 201, press the power button 7 on the printer body 1 to turn on the printer, turn on the Bluetooth of the mobile phone, pair and connect to the printer, open the app matched with this product to take pictures or directly press the shutter button 10 set on the side of the printer body 1 to take pictures;

[0045] Then, the user selects to print the taken photo. After the product receives the data, the paper feed mechanism 4 drives the printing paper to move toward the paper outlet 11. The electric motor 403 drives the corresponding roller shaft 402 and the rubber roller body 401 to rotate, and moves the printing paper toward the paper outlet 11 through the printing assembly 5.

[0046] Finally, the printed paper with the printed photos comes out from the paper outlet 11 and can be torn off by hand after printing. The printed paper is cut by the saw teeth 1201 set at the paper outlet 11. After the printer is used, the locking piece 604 on the back clip 6 is opened and the clamping body 602 is adjusted to remove the product from the back of the mobile phone.
