A hemostatic clip, comprising a clamping assembly and a clip base (4). The clamping assembly comprises a clip body (1) and a steel wire buckle (5) that are sequentially connected. A fixed hinge pin (2) is disposed at the front end of the clip base (4). The clip body (1) is composed of two clamping arms (1a, 1b). The tail ends of the two clamping arms (1a, 1b) are connected through a movable hinge pin (3). The middle of each clamping arm (1a, 1b) is provided with a slide groove (1c, 1d). The fixed hinge pin (2) penetrates through the slide grooves (1c, 1d). The two clamping arms (1a, 1b) reciprocate along the slide grooves (1c, 1d) so that the clip body (1) can be opened and closed. A bent structure (1c1, 1d1) is disposed at the tail end of each slide groove (1c, 1d). When the clamping arms (1a, 1b) move to make the fixed hinge pin (2) located in the bent structures (1c1, 1d1), the two clamping arms (1a, 1b) are located in the locked and closed position.
