The invention discloses an integrated shearing and bent reshaping clamp device of an optical device pin, belonging to the technical field of shearing and bent reshaping clamps of the optical device pins and comprising a hollow box formed by surrounding a left side plate, a right side plate, a vertical plate and a base. A support member is connected to the left side plate and the right side plate and is connected with a top block on which balls are arranged, and a cutting plate is placed on the balls and is connected with an eccentric wheel at the end part of an rocking handle; and the left side plate and the right side plate are clamped with a slide block which is connected with a screw rod through a screw rod fixing block, the slide block is sheathed with a lower plate above which an upper plate is arranged, strip-shaped holes for the optical device pin to be reshaped to penetrate through are correspondingly arranged on the upper plate, the lower plate and the cutting plate, and a blade for shearing the optical device pin to be reshaped is arranged in the strip-shaped hole of the cutting plate. The invention has the advantages of simple operation and good consistency of a shearing effect and a bent reshaping effect, reduces production procedures, improves production efficiency and effectively lowers the risk of damaging the root of the device pin.
