When the rotating direction of the separation cylinder 3 is switched to the opposite direction to make the discharge port 2 generate the airflow outwardly with the negative pressure assembly, the separation cylinder 3 can drive the central seat 11 to rotate together through the first one-way transmission assembly, at the same time, the central seat 11 rotates in this direction, and drives each single tooth of the second one-way tooth disc 18 to be in contact with the second pawl 20 on the wedge-shaped matching side, so that each single tooth of the second one-way tooth disc 18 can be sequentially extruded through the second pawl 20, the second pawl 20 is retracted into the second retraction groove 19 to ensure smooth rotation of the second one-way tooth disc 18, at this time, the separation cylinder 3 drives the central seat 11 to rotate together, and the central seat 11 rotates relative to the support 12; when the rotating direction of the driving assembly driving the separation cylinder 3 is switched to the opposite direction to make the discharge port 2 generate the airflow inwardly with the negative pressure assembly, the separation cylinder 3 can be unlocked to the central seat 11 through the first one-way transmission assembly, at the same time, the central seat 11 rotates in this direction, and drives each single tooth of the second one-way tooth disc 18 to be in contact with the second pawl 20 on the limiting side, so that the position of the second one-way tooth disc 18 and the second pawl 20 can be kept fixed, that is, the central seat 11 is fixed relative to the support 12, at this time, the separation cylinder 3 rotates relative to the central seat 11.

[0068] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various manners without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present application.
