[0028] The main function of the motor 18 is to drive the output shaft 19 to rotate after starting, thereby driving the driving gear 20 to rotate.

[0029] There are two fixed rings 2 and two swivel rings 5 ​​, and the two fixed rings 2 and the two swivel rings 5 ​​are both located on the left and right sides of the connecting block 1 .

[0030] The two rotating rings 5 ​​are used to be rotationally connected with the fixing ring 2 so as to fix the connecting shaft 10 laterally, thereby achieving a fixing effect.

[0031] There are four clamping holes 8 , which are respectively located inside the rotating ring 5 , and the four clamping holes 8 are located on a side of the rotating ring 5 away from the fixing ring 2 .

[0032] The main function of the four clamping holes 8 is to be clamped with the telescopic rod 14 so that the connecting shaft 10 can be effectively fixed inside the connecting block 1, thereby achieving a fixing effect.

[0033] There are four telescopic rods 14 , which are respectively engaged with the four engaging holes 8 . There are four mounting grooves 13 , which are all located inside the rotating ring 5 .

At the same time, the side of the rotating ring 5 close to the connecting block 1 is located inside the rotation groove 1 3, and the clamping block 4 is located inside the rotation groove 2 6. At this time, the fixed ring 2 clamps the rotating ring 5. At this time, the starting motor 18 drives the driving gear 20 to rotate through the output shaft 19, so that the driving gear 20 is meshed with the driven gear 7, so that the rotating ring 5 drives the magnetic roller 11 to rotate, and the printing effect is completed;

[0042] Secondly, when the magnetic roller 11 needs to be disassembled, the telescopic rod 14 is pressed toward the installation slot 13, so that the telescopic rod 14 is separated from the clamping hole 8, and the magnetic roller 11 is pushed at this time, so that the magnetic roller 11 can be quickly disassembled, thereby achieving the effect of facilitating disassembly and installation;

[0043] Finally, the spring 15 will continue to provide elastic force to make the telescopic rod 14 engage with the engaging hole 8, thereby preventing the connecting shaft 10 from falling off.
