Understandably, the embodiment of the invention provides a clutch rope collector, which has the following application principle:

(1) The upper cover 11 is connected with the spool 12, and a user drives the spool 12 to rotate in the process of rotating the upper cover 11.

(2) After the rotating part 10 and the fixed part 20 are assembled up and down, the rotating part 10 is controlled to move up and down relative to the fixed part 20 so as to realize switching rope winding and unwinding. When the user controls the rotating part 10 to move downwards relative to the fixing part 20, the rotating part 10 and the fixing part 20 gradually approach each other until the elastic piece teeth 211 are meshed with the matching piece 111. When the elastic piece teeth 211 are engaged with the engaging piece 111, the engaging piece 111 can only move unidirectionally along the elastic piece teeth 211, i.e., the upper cover 11 is restricted to rotate unidirectionally. When the user continuously rotates the upper cover 11 in one direction, the spool 12 is driven to rotate, so that the rope is collected. When the rope is taken up to a proper position, the upper cover 11 is released, and the current position can be maintained. When the rope is required to be paid out, the user controls the rotating part 10 to move upwards relative to the fixed part 20, namely, the user operates the upper cover 11 to pull up upwards, so that the rotating part 10 and the fixed part 20 are far away from each other, the elastic piece teeth 211 are separated from the matching piece 111, at the moment, the rotating part 10 can rotate freely relative to the fixed part 20, and the spool 12 rotates reversely to release the rope under the action of the rope tension force.

In practice, the clutch retractor is used on wearable articles requiring tethering, such as footwear, medical equipment, and the like. Preferably, the clutch cord is used on a shoe for adjusting the tightness of the shoe cord.

the clutch rope winding device comprises a rotating part 10 and a fixed part 20, and the rotating part 10 and the fixed part 20 are mutually close to or far away from each other to realize the engagement and separation of the elastic piece teeth 211 in the fixed part 20 and the matching pieces 111 in the rotating part 10 so as to quickly control the rope winding and unwinding of the clutch rope winding device; and the rope can not be mutually interfered and blocked in the rope winding and unwinding processes.
