Bar clamp for single-hand operation
 A bar clamp for single hand operation; includes a housing, a fixed jaw and a movable jaw mounted on one end of a slide bar for movement in a direction toward the fixed jaw. A spring-loaded driving key is secured on the slide bar and through operation of a trigger handle engages the slide bar for advancing the movable jaw toward the fixed jaw. A locking key is biased against the slide bar and normally engaged with the slide bar to prevent motion of the second jaw away from the first jaw and actuatable to disengage from the slide bar to allow advancement of the second jaw away from the first jaw. The trigger handle has one end pivotably mounted within the housing and formed with two lateral mounting plates of arched outer configuration. The housing is comprised of a first housing portion and a second housing portion, with at least the driving key and the locking key being accommodated within the housing. The first housing portion has formed on an inside wall thereof a first support member for surrounding one of the mounting plates, and the second housing portion includes a second support member formed on an inside wall of the second housing portion for receiving the other one of the mounting plates.
