Abstract: An auxiliary elastic device for a joint protector is capable of producing auxiliary elasticity for human joints. The device includes a connecting body connected to a multiple of serially and pivotally coupled pivots, a through slot penetrated through the connecting body, and at least one stripe elastic rib movably installed in the through slot and capable of providing an elastic supporting force and an elastic restoring force when human joints are bent, so as to achieve the effect of reducing the burden of the joints.

Abstract: A device of a protection kit especially applied to an ankle, the ankle protection kit has a supporting portion from which a set of mutually opposite fixed portions extend and are pivotally connected therewith; the outer sides of the fixed portions are fixed by means of fixing tapes, so that the entire ankle protection kit can be fixed on the ankle. The structure is characterized in that: the fixing tapes has thereon a male magic tape section, a female magic tape section and an elastic section, the fixing tapes can have an effect of elastically extending by having the elastic section.
