Patent attributes
A clamping device includes a primary member with a central passage and a clamping member connected to the primary member. The clamping member includes an annular body that extends around the central passage between first and second ends. The device also includes an actuator mechanism with an actuator connected to the primary member at a pivot connection, and a pivot arm pivotably connected to the actuator at an eccentric connection spaced from the pivot connection. The actuator pivots between an unlocked position and a locked position, where the pivot arm engages the second end of the clamping member to move the first and second ends closer together. When moving the actuator mechanism from the unlocked to the locked position, the pivot arm travels ahead of the eccentric connection and/or toward the second end of the clamping member. Moving the actuator mechanism from the locked to the unlocked position causes the opposite movement.
