A clamping device comprises a clamping base and a cam mechanism. The clamping base has an opening for receiving at least a part of an object to be clamped and a cavity for receiving the cam mechanism. The cam mechanism is rotatable with respect to the clamping base between a first position, in which the clamping device completely locks the object to be clamped, and a second position, in which the clamping device completely releases from the object. The clamping device can achieve clamping/locking of an object without use of additional tools. In some cases, the clamping device can operated among three different positions, i.e., completely released position, pre-locked position, and completely locked position, facilitating the control and handling of the object. |
