Abstract
A squeeze actuated wrench includes a body, a rotatable socket supported at one end of the body, a driver member for effecting rotation of the socket and a handle adapted to be gripped by the user's hand and rotated relative to the body to actuate the driver member and effect rotation of the socket. One end of the driver member engages the outer peripheral surface of the socket member and defines a first pivot point about which the driver member pivots upon rotation of the socket. The opposite end of the driver member engages the handle and defines a second pivot point about which the handle and driver member rotate relative to each other upon actuation of the driver member and rotation of the socket. The handle is pivotably supported by the body at a third pivot point. A longitudinal axis is defined between the third pivot point and the axis of rotation of the socket member. The first pivot point is located on one side of the longitudinal axis and the second pivot point is located on the opposite side of the longitudinal axis. The first pivot point is adapted to move away from the longitudinal axis and the second pivot point is adapted to move toward the longitudinal axis upon actuation of the driver and rotation of the socket. This arrangement provides a compact squeeze actuated wrench with great mechanical advantage developed by the lever arrangement between the handle and the socket.
