GRIPPING DEVICE

A gripping device, comprising a clamping structure (321f), the clamping structure (321f) comprising a tightening support (3210f), clamping devices (3211f) and a tightening device (3212f), wherein two clamping devices (3211f) are provided, one clamping device (3211f) is slidably arranged at one end of the tightening support (3210f) by means of a first sliding device, and the other clamping device (3211f) is slidably arranged at the other end of the tightening support (3210f) by means of a second sliding device; the tightening device (3212f) drives the two clamping devices (3211f) to move away from or close to each other; the gripping device can be folded or unfolded; when there is no need to clamp a material, a folded gripper has a small volume, so that the folded gripper is less prone to interfering with other structures; and folding and unfolding of the gripping device are both implemented during the movement of clamping members, such that the gripping device has a simple structure.
