ABSTRACT:
A clamping device includes two clamping members pivotally connected with each other and each having a first end and a second end, and a braking mechanism mounted between the second ends of the two clamping members to provide a stepless braking effect to the two clamping members. Thus, the braking mechanism provides a stepless braking effect to the two clamping members, so that the two clamping members are movable toward each other freely so as to shorten and adjust the open angle of the holding portion successively to hold a workpiece and are not movable outward relative each other to stop an outward movement of the two clamping members instantaneously so as to fix the holding portion to clamp the workpiece.
