ABSTRACT OF THE DISCLOSURE
The wrench has a handle with an actuating lever pivoted for operation by a squeezing action to rotate a socket element, which is configured to accept a variety of nuts, bolts and the like. The toothed driving mechanism is incorporated in the main structural components for maximum strength and is positively engaged for the major portion of a squeezing stroke, then releases for quick ratchet action return. In one position of the actuating lever the socket element is locked for powerful leverage action by the handle.
BACKGROUND OF THE INVENTION
The present invention relates to hand tools and particularly to a squeeze action wrench.
Most ratchet wrenches are operated by swinging the handle and are not always practical in confined areas. The ratchet mechanism is usually quite small and will not withstand heavy loads, and is easily jammed by slight deformation or by corrosion.
SUMMARY OF THE INVENTION
The wrench described herein has a handle with a hinged lever portion, the end of the lever itself incorporating the driving teeth, which engage a toothed socket element rotatably mounted in the wrench. Squeezing action of the lever against the fixed handle holds the toothed elements in secure engagement until near the end of a squeezing stroke, then a unique ramp configuration in the handle allows or causes the lever to slide out of engagement with the socket element to return to starting position. The lever will return by ratchet action and, in the starting position, the toothed elements are securely interengaged for certain and maximum leverage to be applied by swinging the entire handle. Interchangeable adapters are used in the socket element, for various sizes and types of nuts and bolts.
