The lower outer side of the dust suction pipe 29 is symmetrically rotated front and back and connected with two groups of connecting blocks 46. The number of each group of connecting blocks 46 is two, and the two connecting blocks 46 are symmetrically arranged up and down. A telescopic rod 47 is connected between the upper and lower connecting blocks 46, and a second spring 48 is sleeved on the outer side of the telescopic rod 47. The two ends of the second spring 48 are respectively connected to the fixed end and the movable end of the telescopic rod 47. The dust suction pipe 29 and the air outlet pipe The lower part of 210 is located between the upper and lower connecting blocks 46 and is set as a bellows structure, so that the dust suction pipe 29 and the lower part of the air outlet pipe 210 can be bent. The outer side of the lower part of the dust suction pipe 29 is connected to an arc rod 49, which is located between the upper and lower connecting blocks 46. The ends of the arc rod 49 are rotatably connected to the adjacent connecting blocks 46 by connecting rods 410. The powder adding hole of the toner cartridge is aligned with the dust suction pipe 29 and the toner cartridge is moved upward. After the sleeve 42 contacts the toner cartridge, the toner cartridge drives the sleeve 42 to move upward. , the first spring 43 is compressed, and the lower ends of the dust suction pipe 29 and the air outlet pipe 210 pass through the powder adding hole and enter the toner cartridge. As the sleeve 42 moves upward and contacts the collar 44, the sleeve 42 drives the collar 44 to move upward together, thereby pulling the lower connecting block 46 upward through the pull rope 45, and the telescopic rod 47 contracts. The second spring 48 is compressed, and the upper and lower connecting blocks 46 move closer to each other and drive the arc rod 49 away from the telescopic rod 47 through the connecting rod 410, so that the bellows structure part at the lower part of the dust suction pipe 29 can be bent to the left (such as Figure 5 As shown in the state, the dust suction pipe 29 can drive the air outlet pipe 210 to bend synchronously, so that the dust suction pipe 29 and the air outlet pipe 210 can be bent toward the left after being inserted into the toner cartridge, ensuring that the airflow can fully blow up the remaining powder inside the toner cartridge.

[0031] like Figure 1 , Figure 7 , Figure 8 and Fig. 9As shown, it also includes a bidirectional screw 51, a rotating shaft 52, a bevel gear 53, a sliding seat 54, a clamping block 55, a movable column 56 and a knob 58. The middle part of the mounting seat 1 is rotatably connected with the bidirectional screw 51, the middle front side of the mounting seat 1 is rotatably connected with the rotating shaft 52, the front end of the rotating shaft 52 is connected with a knob 58, the rear end of the rotating shaft 52 and the middle of the bidirectional screw 51 are connected with mutually meshing bevel gears 53, the top left and right sides of the mounting seat 1 are slidably connected with the sliding seat 54, the sliding seat 54 is threadedly connected with the bidirectional screw 51, the upper part of the sliding seat 54 is connected with a clamping block 55, a plurality of movable columns 56 are slidably connected to the clamping block 55, a chamber 57 is arranged in the clamping block 55, and hydraulic oil is arranged in the chamber 57; The powder box is placed between the clamping blocks 55 on both sides. By turning the knob 58, the bidirectional screw 51 can be driven to rotate through the rotating shaft 52 and the bevel gear 53. The rotation of the bidirectional screw 51 drives the clamping blocks 55 on both sides to move toward each other. After the active column 56 contacts the toner cartridge, the active column 56 stops moving. As the clamping block 55 continues to move, the stopped active column 56 squeezes the hydraulic oil in the chamber 57. The hydraulic oil pushes the active column 56 that is not in contact with the toner cartridge to move the active column 56 toward the toner cartridge. After the active column 56 corresponding to the side of the toner cartridge is completely in contact with the toner cartridge, the toner cartridge is fixed. Through the setting of the active column 56 and the hydraulic oil, it can adapt to the irregular toner cartridge for fixation, thereby enhancing practicality.

[0032] like Figure 6 As shown, it also includes a limiting column 6. A plurality of limiting columns 6 are connected between the outer side of the dust suction pipe 29 and the inner side of the air outlet pipe 210. The limiting columns 6 can limit the gap between the dust suction pipe 29 and the air outlet pipe 210 to ensure that the residual powder can pass smoothly through the gap.

[0033] First, place the toner cartridge under the dust suction tube 29 and the air outlet tube 210, and align the powder adding hole with the dust suction tube 29, then move the toner cartridge upward so that the lower ends of the dust suction tube 29 and the air outlet tube 210 penetrate into the powder adding hole, and at the same time, the toner cartridge squeezes the sleeve 42 upward, and after the sleeve 42 contacts the collar 44, the collar 44 is driven to move upward synchronously, so that the lower connecting block 46 is pulled upward by the pull rope 45, and then the arc rod 49 is driven to move right by the connecting rod 410, so that the dust suction tube 29 and the lower part of the air outlet tube 210 are bent to the left, and at this time, the air nozzle 33 is turned leftward. The toner cartridge is then clamped and fixed by the movable column 56. When the toner cartridge is clamped, the toner cartridge may move adaptively in the left and right directions. The toner cartridge drives the support plate 101 to move adaptively through the sleeve 42 and the sleeve plate 41. After the toner cartridge is fixed, the support plate 101 can be fixed by the fixing bolts. Then the motor 25 is started, and the fan 26 rotates to drive the air flow. The air flow in the mounting shell 22 is discharged from the air outlet pipe 210 and enters from the dust suction pipe 29 at the same time. When the air is discharged from the air outlet 210, the turbine 34 can be driven to rotate, thereby driving the air nozzle 33 to rotate through the turntable 32, so that the air nozzle 33 rotates while blowing out the airflow, ensuring that the residual powder adsorbed on the inner wall of the toner cartridge can be fully blown off, and the dust suction pipe 29 can suck the blown residual powder into the mounting shell 22, the filter screen 27 filters the airflow, and the rotation of the centrifugal separator 28 can settle the residual powder brought in by the airflow in the collecting barrel 24; after the residual powder is cleaned, the motor 25 is turned off, the bidirectional screw rod 51 is reversed, and the two clamping blocks 55 move away from each other to loosen the toner cartridge. , and then the toner cartridge is moved downward, the sleeve 42 moves downward without squeezing the collar 44, and under the action of the second spring 48, the telescopic rod 47 is extended and reset, and the dust suction pipe 29 and the air outlet pipe 210 are straightened and reset; when the residual powder in the collecting barrel 24 needs to be cleaned, the collecting barrel 24 is removed from the mounting shell 22, and then the collecting barrel 24 is cleaned. When the filter 27 needs to be cleaned, the centrifugal separator 28 is unscrewed from the output shaft of the motor 25, and then the casing 23 is removed from the mounting shell 22, and then the filter 27 can be taken out of the mounting shell 22 for cleaning or replacement.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
