A work support includes a mounting plate and a mechanical lock coupled to the mounting plate. The mechanical lock includes a base coupled to the mounting plate and a support pin. The support pin is movably coupled to the base. As such, the support pin can move relative to the base. The work support further includes a locking collar at least partly disposed inside the base. The locking collar surrounds the support pin and includes a first collar portion disposed around the support pin. The first collar portion has an outer tapered surface facing away from the support pin. The locking collar further includes a second collar portion disposed around the support pin. The second collar portion has an inner tapered surface facing toward the support pin and can move relative to the first collar between an unlocked position and a locked position.
