The invention provides a lever-type camber angle corrector which comprises a main body frame on which a fixed connection structure is fixedly disposed, wherein the lower part of a front swinging rod is hinged to the main body frame; the upper part of the front swinging rod is hinged to an ejector rod; a magnet or suction cup is arranged on the top of the ejector rod; an upper support rod protrudesfrom the main body frame to the direction of the front swinging rod; a lower support rod protrudes from the main body frame to the direction of the front swinging rod; the upper part of a rear swinging rod is hinged to the upper support rod; the rear swinging rod and the lower support rod converge; the corresponding converging area of the lower support rod and the rear swinging rod is provided with scales; the two ends of a transverse connecting rod are respectively hinged to the middle of the front swinging rod and the middle of the rear swinging rod respectively. The lever-type camber anglecorrector is a tool simple in structure, low in cost, and capable of observing data during four-wheel alignment in real time and improving working efficiency.
