The utility model discloses an anti-wind device of a pendulum type friction instrument, which relates to the technical field of auxiliary equipment of pendulum type friction instruments and comprises a front plate, a sliding chute is arranged on the inner side surface of the front plate, an inner cavity of the sliding chute is rotatably connected with a bidirectional screw rod, and the side parts of two ends of the bidirectional screw rod are respectively sleeved with a sliding block in a threaded manner. According to the swing type friction instrument windproof device, a rotary knob is rotated to drive a bidirectional lead screw to rotate, the bidirectional lead screw and two sliding blocks are matched to drive the two sliding blocks to move towards the middle of the bidirectional lead screw, and a front plate and a back plate are driven to be gradually separated through movement of the sliding blocks and transmission of a first rotating seat, a connecting plate and a second rotating seat; meanwhile, the shi
