Abstract

The present disclosure relates to field of outdoor sports, and discloses a carabiner capable of adjusting a length of a harness, including a main body. A limit pillar is fixedly arranged at one side of the main body. In the present disclosure, to mount the carabiner capable of adjusting the length of the harness, a clockwork spring is first placed in a groove of the main body, and a hole of a fixed gear is aligned with the limit pillar; then, a moving gear is placed in a clamping pillar of an upper cover; and finally, a lower cover is aligned with the clamping pillar to complete mounting. Through the meshing between the fixed gear and the moving gear, the harness body can be fixed at a specific length, thereby ensuring the safety in high-risk activities such as rock climbing and hiking.
