1. A clamping device comprising:
a primary member comprising a cylindrical body having a front side and a rear side, with a central passage extending in an axial direction from the front side to the rear side and configured for receiving a mounting member therethrough;
a clamping member connected to the primary member and configured for selectively engaging the mounting member when the mounting member is received in the central passage, the clamping member comprising a substantially annular body that extends from a first end peripherally around the central passage of the primary member to a second end, wherein the cylindrical body of the clamping member has a wall surrounding the central passage, wherein a cavity is disposed within the wall of the cylindrical body and a slot extends through the wall, from the cavity to an exterior of the cylindrical body; and
an actuator mechanism engaged with the clamping member and comprising:
an actuator pivotably connected to the primary member at a pivot connection, the actuator further having an eccentric connection spaced from the pivot connection; and
a pivot arm pivotably connected to the actuator at the eccentric connection, wherein the pivot arm engages the second end of the clamping member, wherein the pivot arm and a portion of the actuator forming the pivot connection and the eccentric connection are received within the cavity, and wherein the actuator further includes a handle that extends out of the cavity through the slot,
wherein the actuator mechanism is configured to be moveable by pivoting of the actuator about the pivot connection between an unlocked position, where the first end of the clamping member is spaced from the second end, and the clamping member does not securely engage the mounting member to permit the mounting member to be removed from the central passage, and a locked position, where the pivot arm engages the clamping member to move the first end and the second end closer together, causing the clamping member to securely engage the mounting member to resist movement of the primary member with respect to the mounting member, and
wherein when moving the actuator mechanism from the unlocked position to the locked position by pivoting the actuator, the pivot arm travels ahead of the eccentric connection in a first direction of travel of the eccentric connection, and when moving the actuator mechanism from the locked position to the unlocked position by pivoting the actuator, the pivot arm travels behind the eccentric connection in a second direction of travel of the eccentric connection.
