[0024] Next, specifically describe the specific settings and functions of this embodiment. When disassembling the toner cartridge main body 1 inside the copier, rotate the threaded sleeve 23 by the adjusting rod 24 to make the threaded support rod 26 retract into the threaded sleeve 23. At this time, the distance between the plug connectors 214 at both ends of the toner cartridge main body 1 is shortened, and the gap between the plug connectors 214 and the slide rails installed inside the copier increases, reducing the friction at the installation position. If the deformation of the toner cartridge main body 1 is too large, after rotating the threaded sleeve 23, the plug connectors 214 and the slide rails inside the copier are still stuck. The operator presses the two pulling plates 216 towards each other. At this time, the telescopic rod 211 and the spring 212 are compressed, and then the toner cartridge main body 1 is pulled out from inside the copier, facilitating the disassembly of the toner cartridge main body 1;

[0025] When installing a new toner cartridge main body 1, align the plug connectors 214 with the slide rails inside the copier, and then press the whole downwards. After pressing the whole in place, rotate the threaded sleeve 23 to make the threaded support rod 26 eject from inside the threaded sleeve 23. Push the connecting plate 29, the telescopic rod 211, and the installation plate 213 to move through the threaded support rod 26. Push the plug connectors 214 to be squeezed and fixed with the slide rails through the installation plate 213, facilitating the stable installation of the toner cartridge main body 1.

[0026] Embodiment 2: As Figure 1 - Figure 4As shown in the figure, two limiting sleeves 27 are fixedly connected to the side surface of the connector 22. The two limiting sleeves 27 are symmetrically distributed on the side surface of the threaded sleeve 23. A limiting support rod 28 is inserted into the limiting sleeve 27. The end of the limiting support rod 28 is fixedly connected to the connecting plate 29. Two adjusting rods 24 are fixedly connected to the surface of the threaded sleeve 23. The two adjusting rods 24 are symmetrically distributed on the surface of the threaded sleeve 23. A plurality of guide rods 215 are fixedly connected to the side surface of the mounting plate 213. The plurality of guide rods 215 are evenly distributed on the side surface of the mounting plate 213. The guide rod 215 is inserted into the connecting plate 29.

[0027] The effect achieved by the entire embodiment is that when the threaded support rod 26 pushes the connecting plate 29, the limiting support rod 28 slides along the limiting sleeve 27, improving the stability of the connecting plate 29 during movement. During the process of the connecting plate 29 pushing the telescopic rod 211 to move, the guide rod 215 slides along the limiting hole 210, improving the stability of the plug connector 214 during movement.

[0028] The usage method and working principle of this device: When disassembling the toner cartridge main body 1 inside the copier, the threaded sleeve 23 is rotated by the adjusting rod 24 to retract the threaded support rod 26 into the threaded sleeve 23. If the deformation of the toner cartridge main body 1 is too large, after rotating the threaded sleeve 23, the plug connector 214 is still stuck with the slide rail inside the copier. The operator presses the two pulling plates 216 towards each other. At this time, the telescopic rod 211 and the spring 212 are compressed, and then the toner cartridge main body 1 is pulled out from inside the copier;

[0029] When installing a new toner cartridge main body 1, align the plug connector 214 with the slide rail inside the copier, and then press the whole downwards. After pressing the whole in place, rotate the threaded sleeve 23 to eject the threaded support rod 26 from inside the threaded sleeve 23. The threaded support rod 26 pushes the connecting plate 29, the telescopic rod 211 and the mounting plate 213 to move. The mounting plate 213 pushes the plug connector 214 to be squeezed and fixed with the slide rail. When the threaded support rod 26 pushes the connecting plate 29, the limiting support rod 28 slides along the limiting sleeve 27. During the process of the connecting plate 29 pushing the telescopic rod 211 to move, the guide rod 215 slides along the limiting hole 210.
