Clamping device

A clamping device, comprising:

• a first clamping member, comprising a first side and a second side, wherein the first side and the second side are located on two opposite sides;
• a second clamping member, comprising a third side, a fourth side and a limiting portion, wherein the third side and the fourth side are located on two opposite sides, and the limiting portion convexly disposed on the third side;
• a first connecting rod, one end being pivotally disposed on the first side, and another end being pivotally disposed on the third side, wherein the limiting portion is adjacent to the first connecting rod and located below the first connecting rod, to limit a rotation angle of the first connecting rod;
• a second connecting rod, one end being pivotally disposed on the second side, and another end being pivotally disposed on the fourth side;
• and
• an elastic member, one end being connected to the third side, and another end being connected to the first connecting rod, wherein the elastic member provides a restoring force to make the first connecting rod rotate relative to the second clamping member, to drive the second connecting rod and the first clamping member to rotate, so that a distance between the first clamping member and the second clamping member is shortened to clamp an object.
