Clamping device

The invention discloses a clamping device. The clamping device comprises a frame, a plurality of connecting base and a plurality of manipulators arranged in one-to-one correspondence with the multipleconnecting bases. The frame body comprises a frame plate and a U-shaped fixing frame. Each connecting base comprises a cylinder connected with the frame plate, a connecting shaft rotatably arranged in the cylinder, and a locking mechanism arranged on the cylinder and used for preventing the connecting shaft from rotating. Each manipulator comprises a seat body, wherein two clamping blocks, a clamp mechanism and a power mechanism are slidably arranged at the lower end of the seat body from left to right. According to the clamping device, the multiple manipulators are arranged to clamp or release multiple materials at the same time, so that the clamping efficiency is improved; the clamping blocks, the clamp mechanism and the power mechanism in each manipulator are arranged on the same sideof the corresponding seat
