1. A dispensing device for a clothing treatment apparatus, the dispensing device comprising:
two installation bodies;
a power unit comprising a driving part and a gear lever, wherein the gear lever is rotatably arranged between the two installation bodies, and the driving part is drivingly connected to the gear lever;
a first dispensing unit comprising a first dispensing rod and a first gear, wherein the first dispensing rod is rotatably arranged between the two installation bodies, a first end of the first dispensing rod is provided with a first limiting part, and a second end of the first dispensing rod is provided with a first slippery part; a first threaded part is arranged between the first limiting part and the first slippery part; the first gear is provided with a threaded hole, and the first gear is threadedly connected to the first threaded part through the threaded hole; and after being connected, the first gear is meshed and connected to the gear lever, and the first dispensing rod is connected to a first transmission assembly of a first detergent dispensing chamber; and
a second dispensing unit comprising a second dispensing rod and a second gear, wherein the second dispensing rod is rotatably arranged between the two installation bodies, a first end of the second dispensing rod is provided with a second limiting part, and a second end of the second dispensing rod is provided with a second slippery part; a second threaded part is arranged between the second limiting part and the second slippery part; the second gear is provided with a threaded hole, and the second gear is threadedly connected to the second threaded part through the threaded hole; and after being connected, the second gear is meshed and connected to the gear lever, and the second dispensing rod is connected to a second transmission assembly of a second detergent dispensing chamber; and
when the driving part drives the gear lever to rotate in a forward direction, the first gear moves to reach the first limiting part and drives the first dispensing rod to rotate, so that the first dispensing rod drives the first transmission assembly to move to achieve dispensing of detergent inside the first detergent dispensing chamber, and at the same time, the second gear reaches the second slippery part to achieve slip-rotation; and when the driving part drives the gear lever to rotate in a reverse direction, the second gear moves to reach the second limiting part and drives the second dispensing rod to rotate, so that the second dispensing rod drives the second transmission assembly to move to achieve dispensing of detergent inside the second detergent dispensing chamber, and at the same time, the first gear reaches the first slippery part to achieve slip-rotation.
