The chain fastener group for pets in this creation has an elastic fastener and a ring body, the elastic fastener has an ontology and two hooks, and the hooks are set on the ontology, each hook forming a hook space； the ring body is set in the hook space in a detachable way.Therefore, the user can control the length of the chain buckle group for pets by repeatedly assembling the elastic fastener and the ring body, and can easily set it on the pole body, and can optionally add a branch chain or combine it with other components according to the creativity, so as to increase the diversity of the structure. In addition, because the elastic fastener and the ring body can rotate mutually, the degree of freedom between the structures is increased, which can overcome the traditional The metal chain is unchangeable and has no assembly elasticity.本創作的寵物用鏈扣組具有一彈性扣件和一環體，該彈性扣件具有一本體和二勾件，該等勾件設置於該本體上，各勾件形成有一勾掛空間；該環體以可拆卸方式設置於該勾掛空間內。因此使用者可藉由重複組裝該彈性扣件和該環體，自行控制寵物用鏈扣組的長度，並可輕鬆地設置於桿體上，亦可依創意任意加設支鏈或與其他組件相組合，以此增加結構上的多樣性，另由於彈性扣件和環體間可相互轉動，更增加了結構間的自由度，而可克服傳統金屬鍊一成不變且不具組裝彈性的缺點。
