The invention discloses a general windshield wiper pressure adjusting device for an airplane, and belongs to the field of aviation windshield wiper devices. The general windshield wiper pressure adjusting device comprises a support rod, a swing component and a plate spring. The swinging component comprises a pressure adjusting screw, a base plate, an adjusting plate, a spring, a support arm and arivet, and is arranged between the support rod and the plate spring; one end face of the base plate is of a convex arc structure and is matched with an arc-shaped groove of the support rod. The adjusting plate is of a triangular blocky structure and is located at the joint of the lug piece of the support rod and the support arm. The section of the support arm is of an inverted U-shaped structure,the two ends of the support arm are open, the depth of the U-shaped structure of the support arm is gradually decreased from one end to the other end in the length direction of the support arm, and aninner cavity is used for installing the spring; the pressure adjusting screw is rotated to drive the adjusting plate to rotate, so that the spring is pulled and pressed, and the pressure of the platespring is adjusted; the plate spring used in the device serves as an extension spring pressure adjusting windshield wiper rod piece, and certain pressure is provided for the windshield wiper piece through the elasticity of the plate spring; and the part machining precision and mounting precision are high.
