Seat, a plurality of fasteners, a noose and an auxiliary elastic member hold including a pedestal, one in a kind of benefit beast device system of this creation. Wherein,It holds on seat setting what pedestal,And an elastic element is equipped between the pedestal； Each fastener system is pivotally connected the what pedestal respectively,And this holds seat adjacent to what is abutted against,And limit the position for holding seat； Define noose include a fixing end,One movable end and a fake,Wherein,When the movable end is far from the fixing end,The fake can correspond to diminution,And the outside of each fastener of the fake system winding what； The both ends of auxiliary elastic member link the what fixing end and the movable end respectively,And a thrust is generated to the movable end,So that the fake is generated one and pushes against each fastener to the strength inside contracted； Decline a Hou when this holds a stress,Each fastener is turned to the inside by the pushing and pressing of the fake,The fake is then detached from the respectively fastener Hou and reduces the fake. The main purpose of this creation replaces known metal dentalation in what in the way of noose snare, and then the wound of tearing can be generated to avoid the animal caught by benefit, solves the problems, such as that known clamp-type animals trap causes severe trauma.本創作之一種補獸裝置係包括一底座、一承座、複數個卡扣件、一套繩與一輔助彈性件。其中，承座設置於該底座之上方，並與該底座之間設有一彈性元件；各卡扣件係分別樞接於該底座，並鄰近靠抵於該承座，及限制該承座之位置；定義套繩包括一固定端、一活動端與一繩圈，其中，當該活動端遠離該固定端時，該繩圈即會對應縮小，且該繩圈係繞設於各該卡扣件之外側；輔助彈性件的兩端分別連結於該固定端與該活動端，並對該活動端產生一推力，使該繩圈產生一向內縮的力量推抵各卡扣件；當該承座受力下降後，各卡扣件即受該繩圈的推抵而向內側轉動，該繩圈接著脫離各該卡扣件後縮小該繩圈。本創作之主要目的在於利用套繩圈套的方式取代習知的金屬齒狀結構，進而可以避免被補捉的動物產生撕裂的外傷，解決了習知夾鉗式獵捕器造成嚴重外傷的問題。
