A shaft is arranged on a pair of symmetrically distributed rotating seats. One end of the shaft is rotatably installed on the rotating seat, and a telescopic member is arranged at the other end of the shaft in a sliding manner. Through grooves two are arranged at both ends of the printing roller body, and the telescopic member is inserted into the through grooves two through a driving component.

[0008] Preferably, the driving component includes a spring and a screw. A through groove one is arranged at one end of the shaft. One end of the telescopic member is slidably inserted into the through groove one. The spring is arranged in the through groove one, and both ends of the spring are respectively pressed against the inner wall of the through groove one and one side end face of the telescopic member.

[0009] Preferably, a long groove is arranged on the shaft.

[0021] In order to clearly and completely describe the objectives, technical solutions of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present utility model, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] Please refer toFigures 1-6 , the present utility model provides a technical solution: a detachable printing roller, including a printing roller body 3, characterized in that: rotating seats 1 are symmetrically arranged on both sides of the printing roller body 3, a shaft 2 is arranged on a pair of symmetrically distributed rotating seats 1, one end of the shaft 2 is rotatably installed on the rotating seat 1, and the other end of the shaft 2 is provided with a telescopically installed telescopic member 5. Through grooves two 9 are arranged at both ends of the printing roller body 3, and the telescopic member 5 is inserted into the through groove two 9 through a driving assembly; the driving assembly includes a spring 6 and a screw 4. A through groove one 8 is arranged at one end of the shaft 2, one end of the telescopic member 5 is slidably inserted into the through groove one 8, the spring 6 is arranged in the through groove one 8, and both ends of the spring 6 are respectively pressed against the inner wall of the through groove one 8 and one side end face of the telescopic member 5.

[0024] By arranging the telescopic member 5 and the screw 4, driving the screw 4 to move and then driving the telescopic member 5 to move. By arranging the spring 6, the telescopic member 5 automatically contracts into the through groove one 8 during disassembly.

[0025] Embodiment Two

[0026] On the basis of Embodiment One, a long groove 12 is arranged on the shaft 2. The upper end of the long groove 12 penetrates through the shaft 2, and the lower end of the long groove 12 communicates with the through groove one 8. The screw 4 is slidably inserted along the long groove 12, and the lower end of the screw 4 penetrates and is inserted on the telescopic member 5. The upper end of the screw 4 extends to the outside of the upper end of the shaft 2; a lower groove 13 is arranged on the inner wall of the lower end of the through groove one 8. The lower groove 13 is located on one side close to the port of the through groove one 8, and the lower end of the screw 4 can be threadedly rotatably installed in the lower groove 13; a plurality of groups of convex blocks 7 are arranged in a circumferential array on the arc outer wall of the telescopic member 5 at the outer end of the through groove one 8. A groove one 10 for mating and inserting with the convex block 7 is arranged on the arc inner wall of the through groove one 8. A groove two 11 for mating and inserting with the convex block 7 is arranged on the inner wall of the through groove two 9.

[0027] By arranging the convex block 7 and the groove two 11, the shaft 2 rotates. At this time, the convex block 7 on the telescopic member 5 is pressed against the through groove two 9, thereby driving the rotation of the printing roller body 3. By arranging the lower groove 13 threadedly connected with the screw 4, the screw 4 is fixed, and further the telescopic member 5 is fixed in the shaft 2.
