When the clamping device 10 clamps a workpiece, the connecting rod 12 is first forced to slide along the bar-shaped groove 11a, in this process, the pushing inclined surface 12a of the connecting rod 12 slides to abut against the retreating inclined surface 13a of the clamping piece 13, and as the force acting on the retreating inclined surface 13a by the pushing inclined surface 12a has a component force in the second direction, the clamping piece 13 is far away from the stop piece 14 in the second direction, so that a clamping area for placing the workpiece is formed between the clamping piece 13 and the stop piece 14, then the workpiece is transferred to the clamping area, the force acting on the connecting rod 12 is removed, and finally, the clamping piece 13 is driven to approach the stop piece 14 in the second direction to abut against two opposite sides of the workpiece respectively with the stop piece 14, thereby realizing the fixation of the workpiece.
