[0006] Furthermore, the lock buckle comprises an unlocking end and a locking end, the locking end abuts against the magnetic attraction component, and the force arm of the unlocking end is longer than the force arm of the locking end.

[0007] Preferably, limiting rods are further provided on both sides of the lock buckle, and the buckle body is provided with limiting grooves, and the limiting rods extend into the limiting grooves to limit the rotation angle of the lock buckle.

[0008] Preferably, the limiting groove is in an arc shape, and the curvature of the limiting groove matches the rotational motion trajectory of the lock buckle.

[0009] Preferably, the buckle body is provided with a mounting groove, and the magnetic attraction component is installed in the mounting groove.

[0010] Furthermore, the buckle body is in a step shape, the lower surface is a connecting surface, and the higher surface is a locking surface. The connecting surface is connected to the chicken chest corrector, and the magnetic attraction component is arranged on the locking surface.

[0011] Preferably, one end of the lock buckle that is magnetically connected to the magnetic component is made of ferromagnetic material such as iron.

[0012] Preferably, both sides of the connecting surface are further provided with limiting steps, and the limiting steps are integrally formed with the buckle body.

[0013] Furthermore, an arc transition surface is provided between the connecting surface and the locking surface.

[0014] Preferably, a shoulder strap hole is also provided on one side of the buckle body.

[0015] Compared with the prior art, the buckle of the utility model has fewer assembly parts and a relatively simple structure, which reduces the size of the buckle, reduces the weight of the buckle, and reduces the burden on patients; by utilizing the mutual attraction between the magnetic component and the ferromagnetic material, the lock automatically locks the cassette, making it more convenient for patients to adjust the tightness of the cassette.
