Countersunk screw vibration marking rapid dismounting and mounting clamp

The invention discloses a countersunk head screw vibration marking rapid dismounting clamp which comprises a cam handle (1), a clamp body (2), an ejector rod sleeve (3), a lower ejector rod (4), an ejection air cylinder (5), an upper ejector rod (10) and a locking screw rod (11). A locking screw (11) penetrates into the side face of a clamp body (2), an anti-loose gasket (13) is placed on the locking screw (11), a locking nut (12) is screwed into the locking screw (11), the locking screw (11) is hinged to a cam handle (1), the middle of the locking screw (11) is connected with an ejector rod sleeve (3) through a bolt positioning pin (8) and an easy-to-disassemble handheld bolt (9), a lower ejector rod (4) and an upper ejector rod (10) are installed in the ejector rod sleeve (3), and the upper end of the upper ejector rod (10) is inserted into the clamp body (2). The surface of a part is effectively prevented from being damaged by clamping, the clamped part is prevented from rotating, part clamping and locking
