After the screw passes through the mounting hole on the limiting block, the nut is installed so that the nut of the screw acts as a blocking part aligned with the telescopic end of the cylinder assembly to limit the movement of the telescopic end of the cylinder.
5. The robotic gripper as described in claim 1, characterized in that: The axial direction of the guide shaft is consistent with the movement direction of the clamp mounting component.
