Patent ID: 7406897

Claim:
A clamping device, comprising: two opposite clamping members pivotally connected with each other and each having a first end and a second end; a braking mechanism mounted between the second ends of the two clamping members to provide a stepless braking effect to the two clamping members; wherein the braking mechanism includes a locking member having a first end secured to the second end of a first one of the two clamping members and a second end extended through the second end of a second one of the two clamping members, a braking member pivotally mounted on the second one of the two clamping members and having a locking hole releasably locked on the second end of the locking member, and an elastic member urged between the second one of the two clamping members and the braking member to push the braking member toward the locking member and the second end of the first one of the two clamping members; the braking member of the braking mechanism has a first portion pivotally mounted on the second end of the second one of the two clamping members and a second portion inclined relative to the first portion and having a flat operation face rested on the elastic member; the flat operation face is a straight sheet plate and extends through a whole length of the second portion of the braking member; the elastic member of the braking mechanism is urged between the second end of the second one of the two clamping members and the operation face of the braking member to push the braking member toward the locking member so that the locking hole of the braking member is locked on the locking member at a normal state; the first portion of the braking member has a distal end formed with a hook-shaped pivot portion pivotally mounted on a V-shaped pivot seat formed on the second end of the second one of the two clamping members.
