The invention belongs to elevator safety protection facilities and discloses a safety clamp for a curvilinearly-running elevator. The safety clamp comprises a clamp body, a C-shaped plate spring, an electromagnetic mechanism, a lifting rod and a pair of slider mechanisms, an upper guide wheel and a lower guide wheel are arranged on the top plate and the bottom plate of the clamp body, the C-shaped plate spring is arranged on the front side of a clamp body cavity, a braking wedge seat adjusting mechanism is arranged on a wall body, the electromagnetic mechanism is arranged in the clamp body cavity, the upper end of the lifting rod forms a lifting rod connecting seat while the lower end of the same is connected with a lifting plate, and each slider mechanism comprises a braking wedge seat and a braking wedge. The safety clamp is characterized in that a rotation shaft is arranged on each of the left side plate and the right side plate of the clamp body, a lifting rod actuating mechanism is arranged on the top plate of the clamp body, each slider mechanism comprises a pair of limiting guide plates, a roller frame and a group of rollers, the left sides of the limiting guide plates are matched with the braking wedges while the right sides of the same are fixed to the braking wedge seats, each roller frame is arranged between the corresponding braking wedge seat and the braking wedge, the rollers are arranged along the height direction of the corresponding roller frame, and one sides of the braking wedges contact with the rollers. The safety clamp can guarantee smooth motion, is small in size and simplified in structure and meets requirements on matching between the safety clamp and special guide rails and braking.
