The utility model relates to a beam protection improvement of a joint, wherein the pad body and the pad body extend along the center line and the double end of the pad body, and the pad body is a multi-layered structure of the surface layer, the middle layer and the bottom layer, and is breathable. The elastic elastic body of the telescopic body is provided with a first adjusting fastening portion, and the double end of the other end of the cushion body is provided with a second adjusting fastening portion.When in use, the bottom surface of the cushion body is covered on the inner surface of the joint of the joint, and the double end of the other end of the cushion body is divided and the upper and lower joints of the outer joint are bent and bent, and the cushion is tensioned or relaxed as needed. The elastic force of the body and the tensioning or loosening of the second adjusting fastening portion, and being fastened or fixed to the first adjusting fastening portion to form a V-shaped restraint, when the cushion body is bound to the inner surface of the joint, due to the cushion The air circulation device of the body does not cause sultry heat, and the wall surface strong support force is formed on the inner surface of the joint by the elastic force of the cushion body, and the V-shaped coating with no sultry heat on the double end of the cushion body is used. The beam is bent at the ends of the outer end of the joint, and has a stronger support. It is not only stable and does not slip off during joint movement, and provides a comfortable and sustained support. This makes the combination of the joints easier to use, and the stability and safety are relatively improved.一種關節之束護改良，設墊體及墊體另端延伸之沿中線併靠之雙支端，墊體為面層，中間層，底層等之一多層組合結構並具透氣性亦可伸縮之彈性墊體，面層設有第一調整扣緊部，墊體另端延伸之雙支端，設有第二調整扣緊部。使用時，將墊體底層面覆於關節之彎屈內面，將墊體另端之雙支端，分開跨束關節彎屈外部位之關節上下部，依需要藉由拉緊或放鬆本墊體之彈力與拉緊或放鬆第二調整扣緊部，並粘扣或固定於第一調整扣緊部，形成類V型束縛，當墊體縛束於關節之彎屈內面時，因墊體之空氣流通裝置而不致悶熱，並藉墊體之彈力對關節之彎屈內面部位形成牆面性強支撐力，再加上墊體雙支端無悶熱之V型包覆，分跨緊束住關節彎屈外部之尾凸部位兩端，並
