Abstract: A gripper mechanism is provided, which relates to the technical field of grippers. The gripper mechanism includes a motor, a cylinder barrel, a piston and a guide assembly. The piston reciprocates in the cylinder barrel under the action of the motor and the guide assembly. The piston includes a piston body and a piston rod located in the piston body. Both ends of the cylinder barrel are respectively provided with cylinder heads for limiting the maximum distance and the minimum distance between the piston body and a part to be gripped. The piston rod includes a driving shaft, a cross slider coupling and a gripping head which are connected in turn. The power output by the motor is transmitted to the gripping head through the driving shaft and the cross slider coupling in turn.
