The invention relates an axial parallel four-claw grabber. The axial parallel four-claw grabber comprises a drive part and a main body part, wherein the drive part is composed of a stepping motor, a spiral screw, a spiral screw nut, a push-pull rod, a clamping ring and a support; the main body part is composed of hinge pins, a main body upper board, a main body lower board, grabbing claws and clamping positioning holes. The axial parallel four-claw grabber is characterized in that the spiral screw is connected with the stepping motor, the spiral screw nut is mounted on the spiral screw, the push-pull rod is connected with the spiral screw nut, one end of the push-pull rod is provided with two grooves for determining the position of the clamping ring so that the main body lower board can be positioned, the other end of the push-pull rod has a deep blind hole used as storage space for operation of the spiral screw, the grabbing claws are hinged on the main body main board through the hinge pins, rectangular holes in the main board lower board are used for limiting the grabbing claws, and relative distances of the main body upper board and the main body lower board in space are different, so that the grabbing claws can close and open; the power of the main body lower board comes from the stepping motor and lead screw drive.
