[0007] Further optimization, the outer wall of the first aid and second aid is provided with a protrusion that is attached to the foot, and the support fixing frame is provided with a protrusion corresponding to the first aid and second aid.

[0008] Further optimization, the support fixing frame is divided into a horizontal plate and two vertical plates integrally formed on the horizontal plate, one corner is arranged on the end of the two vertical plates close to the horizontal plate, the distance between the upper portions of the two corner portions is slightly smaller than the distance between the lower portions of the two corner portions, and the upper portions of the two corner portions are inclined inward.

[0009] Further optimized, the fixing groove is divided into a vertical groove and a horizontal groove, and the groove wall of the vertical groove is provided with a slot.

[0010] Further optimized, the vertical plate has locking strips on both sides, and the vertical plate is locked in the vertical groove by the locking groove and the locking strips.

[0011] Further optimized, the horizontal plate is located within the horizontal groove, and the length of the horizontal plate is slightly greater than the length of the horizontal groove, allowing the first and second protective gears to slide slightly outwards.

[0012] Further optimized, the first and second protective gears have several ventilation holes on their side walls.

[0013] Further optimized, the inner walls of the first and second protective gears are provided with a layer of blended material.

[0014] The beneficial effects of this utility model are:

[0015] This protective gear uses 3D printing technology, with the first and second protective gears molded as a single piece, resulting in a better fit and greater comfort. Combined with a support frame and straps, the first and second protective gears are secured to the ankles and calves, making them easy to wear. The first and second protective gears are housed within a frame-shaped support frame, providing greater overall rigidity and better protection.

[0016] The vertical plate of the support frame has a corner at the bottom, and the horizontal plate is slightly longer than the horizontal groove. The first and second protective gears can slide slightly outwards, so they will not constrict the feet and affect blood circulation. This is more friendly to adolescents and children in the development stage and is conducive to rehabilitation. Attached Figure Description
