The invention relates to the technical field of elevator safety tongs, and discloses elevator safety tongs with a buffering function. Theelevator safety tongs comprise a baffle plate, the front surface of the baffle plate is provided with a lifting mechanism, the back surface of the baffle plate is provided with a tong arm, the top of the tong arm is rotatably connected with a tong arm pin shaft, the top of the tong arm is rotatably connected with a threaded pin shaft, a special nut is rotationally connected to the front surface of the threaded pin shaft, a stop tube is fixedly connected to the top of the threaded pin shaft, a belleville spring is fixedly installed on the top of the tong arm, safety tongs are fixedly connected to the back surface of the belleville spring, a lifting rod is fixedly installed on the front surface of the lifting mechanism, a wedge block is arranged on the periphery of the lifting rod, and a wedge block guide plate is fixedly mounted on the front surface of the wedge block. According to the elevator safety tongs with the buffering function, after the safety tongs brake block is lifted, the wedge block clamps an elevator guide rail, the lever principle is utilized, the tong arm rotates through the tong arm pin shaft to compress the belleville spring to provide braking force, and the elevator safety tongs have the braking buffering effect.
