Preferably, the resilient member is a torsion spring, and two ends of the torsion spring are respectively connected with the supporting portion and the outward turning portion.
Through adopting above-mentioned scheme, the torsional spring has good resilience in the moment of torsion, makes the portion of turning up rather than being connected can reset fast, simultaneously, can frequently kick-back repeatedly.
Preferably, the resilient member, the support portion and the outward turning portion are formed by winding an integrally formed elastic wire.
Through adopting above-mentioned scheme, the elastic wire can adopt the most common wire, and it has the cost not high, simultaneously, the convenient advantage of processing.
Preferably, the angle of the tip of the eversion tongue is 140 °.
Preferably, the support part forms an included angle of 135 ° with the everting part 230.
Preferably, the eversion portion has a folding angle of 95 °.
Preferably, the inner portions of the two resilient members are connected by a spring support post.
Through adopting above-mentioned scheme, the spring support post supports two resilience pieces, avoids the resilience piece when receiving great power, the phenomenon of skew appears.
Preferably, a horizontal groove for placing the automatic rebound structure is formed in the outer side wall of the sole.
Through adopting above-mentioned scheme, the structure embedding of kick-backing automatically crouches the inslot, makes the structure of shoes more firm.
(III) advantageous effects
Compared with the prior art, the invention provides a hand-free structure applied to shoes, which has the following beneficial effects:
1) the pair of automatic hands-free lazy shoes solves the problems that a student is difficult to put in a foot and tie a shoelace when getting up to wear the shoes, solves the trouble that the parent wears the shoes for the student, and thoroughly solves the problem that the child is difficult to wear the shoes.
2) And can reduce the troubles of bending down and lifting shoes and tying shoelaces in the application of middle-aged and old people, obesity or patients.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
A hands-free structure applied to shoes comprises a sole 100, an automatic rebounding structure 200 is arranged at the heel position of the sole 100, the automatic rebounding structure 200 comprises two rebounding pieces 210, a supporting part 220 and an outward turning part 230 which are symmetrically arranged, one end of each of the two rebounding pieces 210 is provided with the L-shaped supporting part 220, the outward turning part 230 is of an outward bent tongue-shaped structure, and the opposite ends of the tongue tips of the outward turning part 230 are connected with the other ends of the two rebounding pieces 210;
the angle of the tongue tip of the outward turning part 230 is 120-160 degrees;
the inner angle between the supporting part 220 and the outward turning part 230 is 125-145 degrees;
the bending angle of the everting portion 230 is 85 to 110 °.
In this embodiment, the resilient member 210 is a torsion spring, and two ends of the torsion spring are connected to the supporting portion 220 and the outward turned portion 230, respectively.
In this embodiment, the resilient member 210, the supporting portion 220 and the outward turning portion 230 are formed by winding an integrally formed elastic wire.
In this embodiment, specifically, the angle of the tip of the eversion part 230 is 140 °.
In this embodiment, specifically, the included angle between the supporting portion 220 and the outward turned portion 230 is 135 °.
In this embodiment, the everting portion 230 has a bending angle of 95 °.
In this embodiment, specifically, the insides of the two resilient members 210 are connected by a spring support 300.
In this embodiment, specifically, a horizontal groove 400 for placing the automatic resilient structure 200 is formed on the outer side wall of the sole 100.
Referring to fig. 1 to 4, in children's shoes and middle and old aged shoes, in order to better provide a convenient shoe wearing manner for a user, a design of automatically rebounding a heel without removing the heel with a hand is designed, and the shoe can be better conveniently and simply worn, the lift-free structure is designed to be an outward turning part 230 having an outwardly bent tongue-shaped structure, a double-buffer rebounding member 210 and a supporting part 220 supporting the rebounding member 210, so that the automatic rebounding heel can be reached, the penetration is more convenient, when the shoe is worn, the heel of the foot presses the outward turning part 230 to deform the outward turning part 230, and when the heel enters the shoe, the heel does not press the outward turning part 230 any more, so that the outward turning part 230 is reset under the action of the self elasticity and the rebounding member 210, and the heel can be automatically rebounded.
