In this embodiment, the two pressing pieces 2 are arranged on the left and right sides of the box body 1, and when the pressing pieces 2 are pressed, the two pressing pieces 2 are close to each other. When the pressing pieces 2 are released, the spring 3 pushes the two pressing pieces 2 away from each other.

[0041] As Figures 3-4 shown, the pressing piece 2 includes a pressing plate 21, an upper plate 22 and a lower plate 23, the first opening 210 is arranged on the pressing plate 21, the second opening 220 is arranged on the upper plate 22, and the channel 24 is arranged between the first opening 210 and the second opening 220. Through the above arrangement, when the shoelace passes through the channel 24, the shoelace can be guided.

[0042] As Figures 2-5As shown in the drawings, third openings 11 are respectively arranged at both sides of the upper end of the box body 1, and the second openings 220 can slide relative to the direction of the third openings 11 and make the second openings 220 and the third openings 11 communicate with each other; in this embodiment, the aperture of the second openings 220 is the same as that of the third openings 11, and when the pressing member 2 is displaced, the second openings 220 can communicate with the third openings 11, at this time, the aperture formed after the mutual communication can make the shoelace pass through.

[0043] As shown in the drawings, Figures 2-6 specifically, when the pressing plate 21 is pressed, the pressing member 2 slides to the middle part of the box body 1, so that the aperture of the second openings 220 after the communication with the third openings 11 is increased, so that the shoelace can pass through the second openings 220 and the third openings 11; when the pressing plate 21 is released, the pressing member 2 slides to the outside of the box body 1 by the pushing of the spring 3, the second openings 220 is displaced relative to the third openings 11 and the aperture after the communication with the third openings 11 is reduced, so that the side edges of the second openings 220 and the third openings 11, and the upper surface of the upper plate 22 and the top inner wall of the box body 1 press the shoelace and form the clamping and fixing of the shoelace.

[0044] As shown in the drawings, Figure 3 the side edge of the second openings 220 close to the middle part of the box body 1 has an inclined edge 4, so that the shoelace is gradually tightened by being pressed during the stretching process.

[0045] As shown in the drawings, Figures 3-4 the upper plate 22 and the lower plate 23 are respectively provided with protrusions 5 for preventing the pressing member 2 from being separated, and the top and bottom inner walls of the box body 1 are provided with sliding grooves 6 matched with the protrusions 5. Specifically, the two protrusions 5 are respectively arranged at the edges of the upper plate 22 and the lower plate 23, and the cross section of the protrusion 5 is triangular, so that the pressing member 2 can be more smoothly inserted into the box body 1.

[0046] Patterns or characters are arranged on the outer surface of the box body. Through the above arrangement, the shoelace locking buckle is stylish, so that it is more personalized.

[0047] As shown in the drawings, Figures 2-4 the spring 3 is arranged between the two pressing members 2, and the first positioning column 7 for fixing the spring 3 is arranged at the side of each pressing plate 21 close to the box body 1. In this embodiment, one end of the spring 3 is sleeved on the first positioning column 7, so that the spring 3 does not shift when being pressed.

[0048] As shown in the drawings, Figure 5 a partition 8 is arranged at the inner center of the box body 1, and the partition 8 divides the inner part of the box body 1 into two cavities for the extension and retraction of the pressing member 2. In this embodiment, the two pressing members 2 are respectively arranged in the corresponding cavities.

[0049] Embodiment one:

[0050] As Figure 8 shown, the spring 3 is provided with one, the spring 3 passes through the partition plate 8 and the both ends thereof respectively form abutment with two pressing plates 21. Specifically, the fourth opening 81 for the spring 3 to pass through is opened on the partition plate 8. In the embodiment, the spring 3 is arranged between two pressing plates 21, the both ends of the spring 3 respectively form abutment with the pressing plate 21, so that after the pressing plate 21 is loosened, the spring back force of the spring 3 can push two pressing members 2 away from each other.

[0051] Embodiment two:

[0052] As Figure 8 shown, the spring 3 is provided with two, two springs 3 are respectively arranged in two cavities; one end of the spring 3 abuts against the partition plate 8, and the other end thereof abuts against the pressing member 2 arranged on the same side. Specifically, the second positioning column 9 for fixing the spring 3 is further arranged on both sides of the partition plate 8. Through the above arrangement, two springs 3 can respectively control one pressing member 2 to perform extension and contraction movement, so that selective locking of the shoelace passing through the pressing member 2 can be realized.
