Manipulator clamping jaw quick-change structure

The utility model discloses a manipulator clamping jaw quick-change structure, which relates to the technical field of automatic production equipment, and comprises a manipulator body, a mechanical clamping jaw, a base and three pressing blocks, and the outer wall of the peripheral side of the manipulator body is fixedly sleeved with an upper fixing ring and a lower fixing ring. When the mechanical clamping jaw is used and the mechanical clamping jaw needs to be replaced, the L-shaped pressing block is pressed to drive one rack to move horizontally, then the other rack and the L-shaped pin block are driven to move reversely under the action of the gear, locking of the L-shaped pin block and the pin groove is relieved, the sliding ring slides upwards, and the mechanical clamping jaw is replaced. Under the action of the connecting assembly, the three pressing blocks are driven to synchronously move in the direction of the mechanical arm body, locking of the base and the mechanical clamping jaw is relieved, afte
