[0005] Further, the expansion head includes a first air cylinder and two sets of expansion plates pneumatically connected to the first air cylinder. The first air cylinder has a sliding groove at the bottom. The two expansion plates are mirror-image moved in the sliding groove under the drive of the first air cylinder. The bottom of the expansion plate is also arrayed with a plurality of expansion blocks.

[0006] Further, the take-out clamp includes an L-shaped connecting plate, a clamping cylinder, and two sets of pneumatic clamps. The clamping cylinder is fixedly arranged on the micro-motion assembly through the L-shaped connecting plate. The clamping cylinder has a second sliding groove at the bottom. The two sets of pneumatic clamps are mirror-image moved in the second sliding groove under the drive of the clamping cylinder. The inner side of the end of the pneumatic clamp is also provided with an anti-slip gasket.
