The present invention relates to a dental traction device, the main structure comprising a body, the seat body defines a bonding surface and a fixing member on the other side of the bonding surface, the fixing member has a bending portion and one end of the fixing member A first hook member is connected, and a buckle portion is defined between the bent portion and the base body, and an extension portion is defined between the bent portion and the first hook member. With the above structure, the user can attach the seat body to the teeth by using the bonding surface, and then use the click portion to chuck the elastic member, and the cooperation of the extension portion and the first hook member makes the elastic member more stable and not easy. When it is detached, the efficiency at the time of installation can be increased, and the effect of preventing detachment can be obtained.本新型為有關一種齒科牽引裝置，主要結構包括一座體，座體上界定有一貼合面及一位於貼合面另一側的固定件，固定件上具有一彎折部且固定件的一端處連接有一第一卡勾件，而彎折部及座體之間界定有一卡掣部，彎折部及第一卡勾件之間界定有一延伸部。藉上述結構，使用者可利用貼合面將座體貼合於牙齒上，再利用卡掣部來卡掣彈性元件，並且利用延伸部及第一卡勾件的配合，讓彈性元件更加穩固不容易脫離，如此就可以增加安裝時的效率，且具有防止脫落的效果。
