As a further technical scheme provided by the invention, according to the figures 5 and 7, a track disc 13 is fixedly installed on the base 1, the track disc 13 is embedded in a concave part arranged on the outer wall of one side of the shoelace cord fastener rotating disc 2 facing the base 1, and the four stoppers 3 are engaged with the track disc 13 and move close to or away from the steering axis along with the shoelace cord fastener rotating disc 2. And will not be described in detail.

As a further embodiment of the present invention, as shown in fig. 2, 6, 7 and 8, the locking mechanism 4 comprises a loop bar 41 and a telescopic column 42, wherein the telescopic column 42 extends from the axis of the shoelace holder rotating disk 2 and the rotating cover 6 through a circular hole and is at the same level with the upper surface of the rotating cover 6. Conveniently press release shoelace cable loop rotary disk 2 promptly, also place and be touched by accident.

Furthermore, in the scheme, the four stoppers 3 are far away from the axis along with the rotation of the shoelace cord lock rotating disc 2, and the four stoppers 3 are locked at any position in the distance, and the shoelace cord lock mechanism is realized through the following structures: the top of the tenon rod 12 on the base 1 on the shoelace cord fastener rotating disc 2 is provided with a boring hole 121, the bottom of the inner side of the boring hole 121 is provided with lugs 122 distributed in a circumferential array, the loop bar 41 is axially and rotatably arranged in the boring hole 121, and the end surface facing one end of the boring hole 121 is provided with elastic pawls 411 distributed in a circumferential array. Due to the ratchet and pawl characteristics, the elastic pawl 411 and the projection 122 are engaged, so that the loop bar 41 can only rotate in one direction.

Furthermore, first trapezoidal teeth 22 distributed in a circumferential array are arranged at the port of the circular hole on the shoelace cord fastener rotating disc 2, a holder 421 is arranged on the outer wall of the telescopic column head 42, and second trapezoidal teeth 422 distributed in a circumferential array are arranged on the holder 421; the retractable post 42 is slidably disposed in the loop bar 41 in the axial direction, and engages the second trapezoidal teeth 422 with the first trapezoidal teeth 22 by the spring 43 to keep the shoelace holder rotating disk 2 in synchronization with the locking mechanism 4. In short, when the telescopic stud 42 is pressed, the second step tooth 422 and the first step tooth 22 are disengaged, and if the torsion spring 21 is in the power accumulation state, the shoelace holder rotating disc 2 is unlocked from the loop bar 41 and rotates as the torsion spring 21 is released. Similarly, when the second trapezoidal tooth 422 is engaged with the first trapezoidal tooth 22, and the rotating cover 6 is rotated, the shoelace holder rotating disk 2 rotates along with the rotation, and drives the retractable column head 42 to be synchronous, and the retractable column head 42 drives the loop bar 41 to rotate synchronously. And will not be described in detail.

The working principle is as follows: when the rotating cover 6 is rotated, the shoelace cord lock rotating disc 2 is rotated, the shoelace is tightened, the torsion spring 21 is deformed to store force, and the synchronous check block 3 is diffused outwards under the action of the track disc 13 and is synchronously increased along with the periphery of the shoelace disc. When the rotation of the rotation cover 6 is stopped, the elastic pawl 411 and the protrusion 122 are engaged with each other due to the characteristics of the ratchet and the pawl, so that the loop bar 41 can only rotate in one direction, and the shoelace holder rotating disc 2 stops rotating.

When the portable shoelace needs to be loosened, and the telescopic column cap 42 is pressed, the second trapezoidal tooth 422 and the first trapezoidal tooth 22 are separated from the release of the torsion spring 21, the shoelace is rotated and released by the shoelace holder rotating disc 2, the synchronous stopper 3 is contracted towards the axis under the action of the track disc 13 and is contracted synchronously along with the periphery of the shoelace disc until the torsion spring 21 completely restores the deformation position.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
