[0022] Furthermore, the bottom ends of the two clamping rods 34 are symmetrically equipped with clamping assemblies 4 for facilitating the clamping and grasping of articles. The clamping assembly 4 includes a clamping claw 40, an anti-slip rubber plate 41, a pump body 42, a pressure-resistant box 43, a pressure sensor 44, a first spring 45, a movable plate 46, an auxiliary cylinder 47, a second spring 48 and a T-shaped clamping rod 49.
