In some embodiments of the present application, as shown in fig. 2-3 and 6-9, the driving assembly 300 includes a return spring 330, a pressing handle 310, and a driving member 320 fixedly disposed in the pressing handle 310, wherein a threaded hole 324 is disposed on the driving member 320 along a pressing direction of the pressing handle 310, an external thread 260 matching an internal thread of the threaded hole 324 is disposed at an end of the stirring rod 210 extending out of the toner bottle 100, the driving member 320 is mounted on the external thread 260 at an upper portion of the stirring rod 210, the pressing handle 310 is pressed toward a direction close to the toner outlet 111 while limiting a planar rotation degree of the pressing handle 310, and the internal thread of the driving member 320 moves downward along the external thread 260 on the stirring rod 210 to rotate the stirring assembly 200. That is, during operation, an operator presses the pressing handle 310, so that the pressing handle 310 can only move towards a direction close to the powder outlet 111, but cannot rotate, at this time, the internal thread of the driving member 320 moves downwards along the external thread 260 on the stirring rod 210, the driving member 320 does not rotate, and the stirring rod 210 is forced to rotate, so that the stirring rod 210 stirs the carbon powder at the powder outlet 111.

It is noted that the angle of inclination of the internal thread of the threaded hole 324 and the external thread 260 on the agitator shaft 210 is large, so that when the pressing handle 310 is pressed, the pressing handle 310 is moved downward along the external thread 260 on the agitator shaft 210 by the downward force applied to the pressing handle 310.

With continued reference to fig. 6-9, the driving member 320 includes a fixing portion 321 and a rotating portion 322, a threaded hole 324 is disposed on the rotating portion 322, a mounting space for mounting the driving member 320 is disposed in the pressing handle 310, the fixing portion 321 is fixedly disposed in the mounting space of the pressing handle 310, the fixing portion 321 includes a mounting cavity penetrating through two ends of the fixing portion 321 along the axial direction of the stirring rod 210, the rotating portion 322 is rotatably disposed in the mounting cavity, a rotation limiting member is disposed between the rotating portion 322 and a sidewall of the mounting cavity for preventing the rotating portion 322 from rotating along a first rotation direction, which is opposite to the rotation direction of the stirring assembly 200 driven by the driving member 320, that is, the rotation limiting member 323 limits the rotating portion 322 to rotate only in one direction, that is, when the pressing handle 310 is pressed, the rotating portion 322 tends to move downward and rotate along the direction of the external thread 260 of the stirring rod 210, that is, the rotating portion 322 has a tendency to rotate in the direction opposite to the rotation direction of the stirring rod 210, the rotation restricting member 323 prevents the rotation portion 322 from rotating in the direction opposite to the rotation direction of the agitating bar 210, thereby rotating the agitating bar 210; when the pressing handle 310 and the driving member 320 are reset, the stirring rod 210 is not moved, i.e. does not rotate, the rotating part 322 moves upwards along the direction of the external thread 260 of the stirring rod 210 and rotates, at this time, the rotation limiting member 323 does not limit the rotation of the rotating part 322, thereby realizing that the driving member 320 and the pressing handle 310 are reset without rotating the stirring part 211, and the arrangement makes the pressing handle 310 and the driving member 320 easy to reset. Because the stirring rod 210 is arranged in the carbon powder bottle 100, the stirring blade 251 and the spiral piece 240 are arranged on the stirring rod 210, and the rotation of the stirring rod 210 can be subjected to the resistance given by the carbon powder in the carbon powder bottle 100, when the driving member 320 and the pressing handle 310 are reset, the stirring rod 210 is not moved, the driving rotating part 322 rotates to drive the pressing handle 310 and the fixing part 321 to reset more easily, and the required force is smaller.

In order to enable the driving member 320 and the pressing handle 310 to reset automatically, the reset spring 330 is sleeved at one end of the stirring rod 210 extending out of the toner bottle 100, the reset spring 330 is located between the outer side surface of one end of the toner bottle 100 far away from the toner outlet 111 and the driving member 320, when the pressing handle 310 moves towards the direction close to the toner outlet 111, the reset spring 330 is compressed, when the pressing handle 310 and the driving member 320 reset, the force of the reset spring 330 acts on the driving member 320 to drive the rotating portion 322 to move upwards and rotate, and meanwhile, the pressing handle 310 and the fixing portion 321 also move towards the direction far away from the toner outlet 111 under the driving of the rotating portion 322, so that the resetting of the pressing handle and the driving member 320 is realized.

In some embodiments of the present application, as shown in fig. 9, the rotation limiting member includes a plurality of rotation cylinders, a plurality of abdicating holes 321a are formed in the inner side wall of the installation cavity corresponding to the plurality of rotation cylinders, an opening direction of the abdicating holes 321a is opposite to a rotatable direction of the rotation part 322, a rotation gap is formed between the abdicating holes 321a and the outer side wall of the rotation part 322, and the rotation cylinders can rotate in the rotation gap; the installation cavity is located between two adjacent let position mouths 321a and forms positioning gap 321b between the lateral wall and the outer lateral wall of rotating part 322, and the length of positioning gap 321b in the radial direction of rotating part 322 is less than the radial dimension of the rotating cylinder, and this setting makes the rotating cylinder be located in positioning gap 321b, and the rotating cylinder is blocked in positioning gap 321b and can not rotate. Specifically, when the pressing handle 310 moves towards the direction close to the powder outlet 111, the rotating force of the rotating part 322 brings the rotating cylinder out of the rotating gap and clamps the rotating cylinder in the positioning gap 321b to block the rotating part 322 from rotating; when the pressing handle 310 moves in a direction away from the powder outlet 111, the rotating force of the rotating part 322 brings the rotating cylinder back into the rotating gap, so that the rotating part 322 is rotationally reset, i.e. the rotating part 322 does not rotate when the pressing handle 310 moves in a direction close to the powder outlet 111, and can rotate when the pressing handle 310 and the driving member 320 are reset, i.e. the rotating part 322 can only rotate in one direction.

In the embodiment of the present application, the structure of the driving assembly 300 is not limited to the above structure, and it is within the scope of the present application as long as the stirring rod 210 can be driven to rotate. For example, the structure of the driving assembly may be as follows: the driving assembly comprises a motor and a motor mounting seat, the motor is mounted on the motor mounting seat, the motor mounting seat is detachably arranged on the image forming equipment, one end of the stirring rod, which extends out of the carbon powder bottle, is connected onto an output shaft of the motor, and the motor drives the stirring rod to rotate so as to stir carbon powder at the powder outlet.

The sliding protrusion 313 cooperates with the limiting chute 142 to limit the pressing handle 310, so that the pressing handle 310 can only move in a direction close to or away from the powder outlet 111, and the pressing handle 310 cannot rotate when moving in the direction close to or away from the powder outlet 111, that is, the planar rotation freedom of the pressing handle 310 is limited.
