A convex groove is opened on one side of the mounting frame. A convex block is slidably connected inside the convex groove. A first half hexagon block is fixedly connected to one side of the convex block. A second half hexagon block is fixedly connected to one side of the mounting frame. Two through grooves are opened on one side of the first half hexagon block. A limiting plate is fixedly connected inside the through grooves. A limiting hole is opened on one side of the limiting plate. A push rod is slidably connected inside the limiting hole. A connecting plate is fixedly connected to the other side of the push rod.

[0008] Preferably, a return spring is fixedly connected to the other side of the limiting plate, and the other side of the return spring is fixedly connected to one side of the connecting plate.

[0009] Preferably, a tension spring is fixedly connected to the top of the convex block, and the top of the tension spring is fixedly connected to the top of the inner cavity of the convex groove.

[0010] Preferably, semi-circular grooves are formed in the bottom of the first semi-hexagonal block and the top of the second semi-hexagonal block, and a plurality of rollers are rotatably connected to the inside of the semi-circular grooves through a rotating shaft.

[0011] Preferably, a polyurethane texture is provided on the surface of the developing roller body.

[0012] Technical effects and advantages of the present utility model:

[0013] In the present utility model, by moving the push rod towards the inside of the through groove, the push rod drives the connecting plate and the clamping block to move, so that the clamping block disengages from the inside of the L-shaped clamping groove. Subsequently, by moving the first semi-hexagonal block upwards, the first semi-hexagonal block is separated from the second semi-hexagonal block. Immediately afterwards, the developing roller body is pulled out from the mounting frame, thereby realizing the rapid disassembly of the developing roller body. This process not only improves the working efficiency, but also reduces the time and labor intensity required for maintaining the developing roller. BRIEF DESCRIPTION OF THE DRAWINGS

The number of installation frames 1 is two. A shaft rod 3 is placed inside the installation frame 1. A developing roller body 2 is installed on the surface of the shaft rod 3. A convex groove 4 is opened on one side of the installation frame 1. A convex block 5 is slidably connected inside the convex groove 4. A first half hexagonal block 6 is fixedly connected to one side of the convex block 5. A second half hexagonal block 7 is fixedly connected to one side of the installation frame 1. Two through grooves 8 are opened on one side of the first half hexagonal block 6. A limiting plate 9 is fixedly connected inside the through groove 8. A limiting hole 10 is opened on one side of the limiting plate 9. A push rod 11 is slidably connected inside the limiting hole 10. The other side of the push rod 11 is fixedly connected to an adapter plate 12. A clamping block 13 is fixedly connected to one side of the adapter plate 12. Two L-shaped clamping grooves 14 are opened on the top of the second half hexagonal block 7. The staff moves the push rod 11 in the direction of the inside of the through groove 8, so that the push rod 11 drives the adapter plate 12 and the clamping block 13 to move, so that the clamping block 13 disengages from the inside of the L-shaped clamping groove 14. Then, by moving the first half hexagonal block 6 upward, the first half hexagonal block 6 is separated from the second half hexagonal block 7. Immediately afterwards, the developing roller body 2 is pulled out from the installation frame 1, thereby realizing the quick disassembly of the developing roller body 2. This process not only improves the work efficiency, but also reduces the time and labor intensity required for maintaining the developing roller.

[0022] Referring to Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , in this implementation: The surface of the clamping block 13 is slidably connected to the inside of the L-shaped clamping groove 14. The size of the clamping block 13 is adapted to the internal size of the L-shaped clamping groove 14. The size of the clamping block 13 is adapted to the internal size of the L-shaped clamping groove 14, ensuring that there will be no looseness or tightness during the sliding process, thereby improving the stability and reliability of the overall structure.

[0023] Referring to Figure 4 As shown in Figure 4 , in this implementation: A return spring 15 is fixedly connected to the other side of the limiting plate 9. The other side of the return spring 15 is fixedly connected to one side of the adapter plate 12. When the staff moves the push rod 11 inside the through groove 8 and drives the adapter plate 12 to move, the return spring 15 will start to store energy. When the push rod 11 stops moving, the return spring 15 will push the adapter plate 12 back to the initial position, making it more convenient for the staff to use.

[0024] Referring to Figure 2As shown in the figure, in this embodiment: A tension spring 16 is fixedly connected to the top of the convex block 5, and the top of the tension spring 16 is fixedly connected to the top of the inner cavity of the convex groove 4. After the first half hexagon block 6 is separated from the second half hexagon block 7, the tension spring 16 will drive the first half hexagon block 6 to move upward quickly, making the disassembly process of the developing roller body 2 more convenient and rapid.

[0025] Refer to Figure 3 As shown in the figure, in this embodiment: Semi-circular grooves 17 are provided at the bottom of the first half hexagon block 6 and the top of the second half hexagon block 7. A plurality of rollers 18 are rotatably connected to the inner part of the semi-circular grooves 17 through rotating shafts. Through the arrangement of the plurality of rollers 18, the shaft rod 3 can rotate more smoothly, reducing the friction force.

[0026] Refer to Figure 1 As shown in the figure, in this embodiment: The surface of the developing roller body 2 is provided with polyurethane patterns. The polyurethane material has excellent wear resistance and chemical corrosion resistance, which can effectively extend the service life of the developing roller body 2. In addition, the surface roughness of the polyurethane patterns is moderate, which can ensure the uniform distribution of the developer on the surface of the developing roller body 2, thereby improving the clarity and contrast of the image.

[0027] Working principle: The staff moves the push rod 11 in the direction of the inside of the through groove 8, so that the push rod 11 drives the connecting plate 12 and the clamping block 13 to move, making the clamping block 13 disengage from the inside of the L-shaped clamping groove 14. Subsequently, by moving the first half hexagon block 6 upward, the first half hexagon block 6 is separated from the second half hexagon block 7. Then, the developing roller body 2 is pulled out from the mounting frame 1, thus realizing the rapid disassembly of the developing roller body 2. This process not only improves the work efficiency, but also reduces the time and labor intensity required for maintaining the developing roller. The size of the clamping block 13 is adapted to the internal size of the L-shaped clamping groove 14, ensuring that there will be no looseness or tightness during the sliding process, thereby improving the stability and reliability of the overall structure. When the staff moves the push rod 11 inside the through groove 8 and drives the connecting plate 12 to move, the return spring 15 will start to store energy. After the push rod 11 stops moving, the return spring 15 will push the connecting plate 12 back to the initial position, making it more convenient for the staff to use. After the first half hexagon block 6 is separated from the second half hexagon block 7, the tension spring 16 will drive the first half hexagon block 6 to move upward quickly, making the disassembly process of the developing roller body 2 more convenient and rapid. Through the arrangement of the plurality of rollers 18, the shaft rod 3 can rotate more smoothly, reducing the friction force. The polyurethane material has excellent wear resistance and chemical corrosion resistance, which can effectively extend the service life of the developing roller body 2. In addition, the surface roughness of the polyurethane patterns is moderate, which can ensure the uniform distribution of the developer on the surface of the developing roller body 2, thereby improving the clarity and contrast of the image.
