The specific settings are as follows:

[0045] Please refer to Figures 1 to 3 The side support rod frame 1 includes two groups of support rod bodies 11. The bottom ends of the two groups of support rod bodies 11 are respectively provided with first direction adjustment assembly parts 12, which are connected to the fuselage through the first direction adjustment assembly parts 12 by means of fasteners in a positionable transfer assembly. In this way, the extension direction of the support rod body 11 can be flexibly and adaptively adjusted, and it is more convenient to fold and store the entire foot limiting structure.

[0046] The adaptive limiting belt 2 includes a limiting belt body 21 and two groups of second direction adjustment assembly parts 22 respectively arranged at the two end parts of the limiting belt body 21 in a one-to-one manner. The limiting belt body 21 is configured as a flexible limiting belt body, and the two end parts of the limiting belt body 21 are respectively and one-to-one connected and assembled at the top ends of the two groups of strut bodies 11 through two groups of second direction adjustment assembly parts 22, so that the limiting belt body 21 can be further adjusted in direction based on the two groups of strut bodies 11, and then its rear side limiting extension position can be adjusted in a targeted manner, thereby being more suitable for shoes of different sizes and improving functional practicality.

[0047] As an optional solution of this embodiment, both groups of the second direction adjustment assembly parts 22 are configured as positionable adapter parts, and their positioning parts can be but are not limited to bolt fasteners and pin fasteners, so as to make the limiting state formed by the limiting belt body 21 after being adjusted to the predetermined position safer and more stable.

[0048] Please continue to refer to Figures 1 to 3 There are two groups of strap fixing rings 3, and the two groups of strap fixing rings 3 are respectively connected and assembled with the two groups of the second adjustment assembly parts 22, so as to utilize the independently rotatable design of the two groups of strap fixing rings 3 so that the fastening position of the connecting strap corresponding to the shoe body can be more adapted to the rear limiting extension position of the adaptive limiting belt 2, thereby making the transmission angle of the strap binding force acting on the shoe body more stable, significantly improving the overall functional practicality.

[0049] As another optional scheme of this embodiment, the strap fixing ring 3 includes a fixing ring base portion and a strap wrapping portion; wherein, the fixing ring base portion and the second adjustment assembly portion 22 are connected and assembled with each other, and the strap wrapping portion can be assembled on the fixing ring base portion in a fixed-axis swinging manner, and the swing axis of the strap wrapping portion is arranged parallel to the rotation surface of the fixing ring base portion, so as to further effectively improve the flexible adaptability and functional practicality of the strap corresponding to different shoe body shapes.
