The utility model is a kind of joint shaft protector of related what,Its include with user joint bending cooperation actuation connecting rod mould group,The plural block member that limiting rod mould group actuation range must be contradicted through being displaced,Respectively with the thumb wheel element of each block member connection and respectively selective each thumb wheel element of clip limit element； And when using when connecting rod mould system with joint bending cooperation in the actuation of the multiaxis heart to meet ergonomics,And first manipulate thumb wheel element when joint to be limited and drive block member displacement,And thumb wheel element is fixed by limit element,Therefore will drive connecting rod mould group when joint desire activity,And connecting rod mould group actuation be by block member block and limitation,Range of motion is allowed to be restricted or direct fixing joint,It thereby enables the utility model reach and uses and operate limitation scope of activities convenience,And the fixed what any angle of view demand is obtained,And meets ergonomics and allow using more comfortable practical improvement.本新型為有關於一種關節轉軸護具，其包括有隨使用者的關節彎折配合作動之連桿模組、複數得經位移來抵觸限制連桿模組作動範圍之擋止元件、分別與各擋止元件連結之撥輪元件及分別選擇性卡掣各撥輪元件之限位元件；而當使用時連桿模組係隨關節彎折配合呈多軸心作動以符合人體工學，且欲限制關節時先操控撥輪元件帶動擋止元件位移，並由限位元件固定撥輪元件，故當關節欲活動時會帶動連桿模組，且連桿模組作動乃受到擋止元件擋止及限制，讓關節活動範圍受到限制亦或直接固定關節，藉此令本新型達到使用和操作限制活動範圍便利，且得視需求固定於任意角度，並符合人體工學讓使用更為舒適之實用進步性。
