Novel clamping device for automobile seat production line

The invention discloses a novel clamping device for an automobile seat production line. The invention provides a novel clamping device for an automobile seat production line. The novel clamping devicecomprises a clamping air cylinder, a supporting piece mounting plate, a hinge piece, a movable arm, a clamping jaw connecting arm, a clamping jaw, a hinge plate, a supporting piece and a limiting assembly. By arranging the clamping air cylinder, the supporting piece mounting plate, the hinge piece, the movable arm, the clamping jaw connecting arm, the clamping jaw, the hinge plate, the supportingpiece and the limiting assembly, under the condition that an object is clamped between the clamping piece and the supporting piece, once the clamping air cylinder breaks down and an air cylinder rodcannot retract, the clamping jaw connecting arm can rotate upwards and independently relative to the movable arm by operating the limiting assembly, and thus, the object clamped between the clamping jaw and the supporting piece
