Abstract: The present invention discloses a lock catch for pet traction, which comprises a traction hook and a pull ring connected with one end of the traction hook. The traction hook comprises a hook body, an even number of swinging resetting mechanisms and cylindrical pins. The hook body comprises a first connecting part and two installing parts; every two swinging resetting mechanisms form a group and are symmetrically penetrated in corresponding through holes; each swinging resetting mechanism comprises a swinging arm and a torsion spring; one end of each group of swinging arms positioned on the outer side of the installing part is positioned at a lower stopping point, and the other end can be mutually abutted against each other; and open ends limited by the two installing parts and the first connecting part are closed. The present invention has novel appearance, flexible and convenient use and difficult unhooking.

Abstract: A buckle structure includes a hook-shaped buckle body and a movable bolt. The hook-shaped buckle body includes a question mark-shaped body and a blocking section provided at an upper end thereof, a receiving cavity is formed between the movable bolt and the question mark-shaped body. The lower end of the movable bolt is hinged at the lower end of the question mark-shaped body, the upper end of the movable bolt is elastically contacted with the upper end of the question mark-shaped body. the contact point of the movable bolt and the hook-shaped buckle body is located in the middle of the hook-shaped buckle body, so that the buckle can be easily mounted on the buckle structure as long as the buckle is sleeved on the blocking section and the buckle is moved in the direction of the receiving cavity.
