The bottom of the printing body 1 has an electrical placement groove 11 and a vacant groove 16. The electrical placement groove 11 and the vacant groove 16 are arranged in communication. The electrical placement groove 11 is used to assemble the power supply component 2. The power cord 3 is located in the vacant groove 16, and both ends of the power cord 3 are respectively docked and connected with the printing body 1 and the power supply component 2; the printing body 1 includes a bearing plate 13. The bearing plate 13 is used to bear the power supply component 2 and is used to limit the power supply component 2 from detaching from the electrical placement groove 11.

[0028] For the above-mentioned built-in power supply type printer, the power supply component 2 is assembled in the printing body 1 through the electrical placement groove 11, and then the conduction between the printing body 1 and the power supply component 2 is realized through the power cord 3 arranged in the vacant groove 16, so as to realize the power supply of the power supply component 2 to the printing body 1, and realize the flexible use of the thermal printer without relying on the mains power. Moreover, under the action of the bearing plate 13, the setting stability of the power supply component 2 is improved, and the assembly of the power supply component 2 is guaranteed. In addition, the power supply component 2 is assembled in an embedded manner, reducing the overall occupied space, facilitating the layout and use of the printer. At the same time, neither the power supply component 2 nor the power cord 3 is exposed, effectively reducing the accidental detachment of the power cord 3 and the power supply component 2, ensuring the connectivity stability of the circuit, and ensuring the normal use of the printer.

[0029] The electrical placement groove 11 includes an external groove 111 and a limiting groove 112. The external groove 111 and the limiting groove 112 are arranged in communication. The bearing plate 13 is arranged corresponding to the limiting groove 112; during assembly, the power supply component 2 is synchronously embedded in the external groove 111 and the limiting groove 112.

[0030] In this way, through the cooperation of the bearing plate 13 and the limiting groove 112, the power supply component 2 is limited and positioned, and the assembly stability of the power supply component 2 is improved.

[0031] The printing body 1 includes a positioning strip 12. The positioning strip 12 is arranged in a long strip shape. The positioning strip 12 and the bearing plate 13 are arranged in an overlapping manner. The positioning strip 12 has a positioning surface, and the positioning surface is arranged in an arc shape.
