In some embodiments, the retractor retracts a first stroke, for example, 10mm to 18mm, while the retractor drives rod 1211 rotates 11 ° to 19 °, specifically, rod 1211 may rotate clockwise, rod 1211 rotates while driving fork 1212 to rotate, fork 1212 is coupled to guide 1221, such that during rotation of fork 1212, guide 1221 is axially movable 7mm to 15mm relative to mount 1222, thereby moving retractor drive guide 1221 upward. The retracting stroke of the retractor can be set according to actual needs, and it can be understood that the driving stroke of the retractor is positively correlated to the preset angle of rotation of the driving lever 1211, that is, the larger the retracting stroke of the retractor is, the larger the angle of rotation of the driving lever 1211 in the clockwise direction is, and further, the displacement of the axial movement of the guide 1221 is larger, that is, the preset angle of rotation of the driving lever 1211 is positively correlated to the displacement generated by the guide 1221. It can be understood that the tractor does not have to have an excessively large stroke, and if the tractor has an excessively large stroke, the displacement of the corresponding guide 1221 in the axial direction is relatively large, so that the clutch device 100 has a relatively large volume, and the occupied space of the laundry treating apparatus is increased.

Further, the tractor stroke is not easy to be too small, and if the tractor stroke is too small, the movement displacement of the corresponding guide 1221 is small, and the movement displacement corresponding to the first clutch assembly 140 is also small, so that the difficulty in matching between the first clutch assembly 140 and the rotating shaft assembly 110 is increased. Therefore, it is necessary to design the stroke of the retractor reasonably, for example, the first stroke of the retractor may be set to 14mm, the rotation angle of the driving lever 1211 is 15 °, the moving displacement of the corresponding guide 1221 is 11mm, and the driving stroke of the second driving device 123 is 11mm, so that the moving stroke of the first clutch assembly 140 is also 11mm, which is consistent with the moving stroke of the guide 1221, and the fitting stability between the first clutch assembly 140 and the rotating shaft assembly 110 can be ensured while simplifying the structure of the laundry treatment apparatus.

It can be understood that the retractor can also comprise multiple strokes, such as a second stroke, a third stroke and the like, and specifically, the distance of the multiple strokes can be consistent with the first stroke, and can also be specifically set according to actual needs.

Through setting up first drive arrangement 121, can drive guide 1221 and remove multistage stroke, and then make and present different cooperation states between first clutch assembly 140 and the pivot subassembly 110 to under the drive of driving piece 161, first clutch assembly 140 can drive first pivot 111 or second pivot 112 and rotate, or first pivot 111, second pivot 112 and third pivot 113 rotate simultaneously.

In this embodiment, a specific structure of the second driving device 123 is defined, specifically, the second driving device 123 includes a first elastic member 1231, the first elastic member 1231 is capable of being in a compressed state when the second clutch assembly 122 cancels the stop of the first clutch assembly 140, specifically, the first elastic member 1231 is in an initial state, and one end of the first elastic member 1231 abuts against the third clutch member 143, when the first driving device 121 drives the guide member 1221 to move axially relative to the fixing member 1222, the guide member 1221 cancels the stop of the second clutch member 142, at this time, the first elastic member 1231 is capable of driving the third clutch member 143 to move, the third clutch member 143 moves to push the second clutch member 142 to move, and the second clutch member 142 simultaneously pushes the first clutch member 141 to move, so as to realize the change of the relative engagement position between the first clutch assembly 140 and the rotating shaft assembly 110.

In detail, since the initial state of the first elastic member 1231 is a compressed state, that is, under the condition that the first driving device 121 does not drive the guide member 1221 to move axially, at least a portion of the guide member 1221 abuts against at least a portion of the second clutch member 142 to stop the first clutch assembly 140, at this time, the first elastic member 1231 is in a compressed state, when the first driving device 121 drives the guide member 1221 to move, because the portion of the guide member 1221 abutting against the second clutch member 142 is released from abutment, the first elastic member 1231 can generate an elastic force which can drive the first clutch assembly 140 to move axially, so that the first clutch assembly 140 changes the engagement position with the rotating shaft assembly 110 in the moving process, thereby implementing a plurality of different driving manners, without using a planetary gear reduction mechanism in the related art to perform power steering and speed conversion of the clutch assembly 100, the structure of the clutch device 100 can be simplified, and the cost of the entire clutch device 100 can be reduced.
