[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] As Figure 1 and Figure 2 shown, a toner cartridge 100 is used for detachably docking with a machine drive head 1 on a laser printer 11. The toner cartridge 100 includes a cartridge body that is adaptively installed. Specifically, the cartridge body includes a storage body 2, a rear cover portion 3, and a front shell portion 4. In addition, the toner cartridge further includes a control member 5, a guiding member 6, and a driving force receiving member 7 provided on the cartridge body.

[0025] Embodiment 1

[0026] Specifically, as Figure 2 and Figure 3 shown, a through hole 40 is formed at the front end of the front shell portion 4, and the driving force receiving member 7 is rotatably disposed in the through hole 40.

[0027] First clamping positions 70 and second clamping positions 71 are respectively formed at both ends of the driving force receiving member 7. A first clamping portion 10 is formed at one end of the machine drive head 1. The first clamping portion 10 and the first clamping position 70 are adaptively clamped. After the first clamping portion 10 and the first clamping position 70 are docked, when the machine drive head 1 rotates in the first direction, the driving force receiving member 7 is driven to rotate by the machine drive head 1. After the driving force receiving member 7 rotates in the second direction (the second direction is the reverse of the first direction), the first clamping position 70 and the first clamping portion 10 are disengaged, which is convenient for disassembly and assembly.

[0028] A second clamping portion 61 is formed at one end of the guiding member 6 close to the driving force receiving member 7. A second spring 12 for forcing the second clamping portion 61 to engage with the second clamping position 71 is provided on the other side of the guiding member 6 away from the driving force receiving member 7. Through the cooperation of the second clamping portion 61 and the second clamping position 71, when the guiding member 6 and the driving force receiving member 7 rotate in the second direction, the second clamping portion 61 and the second clamping position 71 are in a clamped state. At this time, the guiding member 6 can drive the driving force receiving member 7 to rotate. The second clamping portion 61 is a protrusion structure, and a slope is provided on one side of the protrusion structure. When the second clamping position 71 moves in the first direction, the second clamping portion 61 and the second clamping position 71 do not engage with each other, and the driving force receiving member 7 does not drive the guiding member 6 to rotate.

[0029] A guide rail 60 is provided along the spiral guide on the outside of the guide member 6. One end of the control member 5 is formed with a guide projection 50 which is slidably engaged with the guide rail 60, so that when the control member 5 moves in a direction away from the driving force receiving member 7, it can force the guide member 6 to move in the second direction. Preferably, the control member 5 passes through the housing 2 and the rear cover portion 3 and is connected to the rear cover portion 3. When the toner cartridge needs to be disassembled, the door 8 is opened and the control member 5 is pulled outwards. When the control member 5 moves in a direction away from the driving force receiving member 7, it forces the guide member 6 to move in the second direction. The second engaging portion 61 and the second engaging position 71 are engaged, and the guide member 6 drives the driving force receiving member 7 to rotate in the second direction, driving the first engaging position 70 to disengage from the first engaging portion 10, so that the toner can be taken out smoothly.

[0030] In some embodiments, the control member 5 is disposed outside the housing 2.

[0031] Embodiment 2

[0032] In this embodiment, as Figure 4 , a positioning portion 20 is formed on the outside of the housing 2. The control member 5 movably passes through the positioning portion 20. A limiting portion 51 is formed on the control member 5. The first elastic member 9 abuts against the positioning portion 20 and the limiting portion 51 to force the control member 5 to move in a direction away from the driving force receiving member 7. Preferably, a first spring member 9 which elastically abuts between the positioning portion 20 and the limiting portion 51 is sleeved on the control member 5. One end of the control member 5 extending outside the rear cover portion 3 abuts against the inner side of the door 8 on the laser printer. When the door 8 is closed, the first spring member 9 is in a compressed state. When the door 8 is opened, the reset force of the first spring member 9 drives the control member 5 to move in a direction away from the driving force receiving member 7, so that the guide member 6 drives the driving force receiving member 7 to move in the second direction, and the machine driving head 1 and the driving force receiving member 7 are disengaged, without manually pulling the control member 5.

[0033] Similarly, a guide rail 60 is provided along the spiral guide on the outside of the guide member 6. One end of the control member 5 is formed with a guide projection 50 which is slidably engaged with the guide rail 60. The control member 5 passes through the housing 2 and the rear cover portion 3. When installing the toner cartridge, first place the toner cartridge into the laser printer for installation, and push the control member inward. The guide member 6 rotates. At this time, the second engaging portion 61 and the second engaging position 71 are not engaged, and the first engaging portion 10 and the first engaging position 70 are engaged. When the door 8 is in the closed state, the first elastic member 8 is in a compressed state. The driving force receiving member 7 is driven to rotate by the machine driving head 1 for powder supply. When the door 8 is opened, the first elastic member 8 forces the control member 5 to move in a direction away from the driving force receiving member 7. The second engaging portion 61 and the second engaging position 71 are engaged, and the guide member 6 drives the driving force receiving member 7 to move in the second direction, driving the first engaging position 70 to disengage from the first engaging portion 10, and the toner is taken out.

[0034] In some embodiments, the control member 5 is disposed outside the housing 2.

[0035] Example 3

[0036] As Figure 5 and Figure 6 shown, a connecting member 20 is formed on the outer side of the side portion of the cartridge body 2. A sliding groove 42 is formed on the side portion of the front shell portion 4 and is engaged with the connecting member 20. A first protrusion 21 (the portion to be limited) is formed at the front end of the connecting member 20, and a second protrusion 41 (the limiting portion) is formed at the rear side of the sliding groove 42. The second protrusion 41 and the first protrusion 21 can abut against each other. The control member 5 passes through the cartridge body 2. It can be understood that the cartridge body 2, the rear cover portion 3 and the front shell portion 4 can slide relative to each other. When the toner cartridge is taken out, after the rear cover portion 3 and the cartridge body 2 are pulled a certain distance, the cartridge body 2 abuts against the control member 5, and the control member 5 is pulled. The guiding member 6 drives the driving force receiving member 7 to move in the second direction, and the first engaging position 70 is disengaged from the first engaging portion 10. Similar to Example 1, after the machine driving head 1 and the driving force receiving member 7 are disengaged, the cartridge body 2 continues to move outwards. Until the first protrusion 21 and the second protrusion 41 abut against each other, during the process of continuing to move outwards, the front shell portion 4 is driven to move together, realizing the overall movement of the entire toner cartridge.

[0037] In some embodiments, the control member 5 is disposed outside the cartridge body 2.
