Torque limiting wrench with an audio alarm

A torque wrench for limiting the magnitude of torque applied to a load comprising:

• a fore-section rod having first and second ends, a head structure of a wrench at said first end, a fore-section member at said second end, said fore-section member forming two prongs having opposing spaced prestress coupling faces on the interior defining a cavity, and exterior faces,
• a rear-section rod having a rear-section member,
• pivot means for connecting said fore-section member to said rear-section member, and for permitting pivoting of said rods,
• said rear-section rod having upper and lower ends, said rear-section member at said upper end forming two flanges having interior surfaces on the interior sides of said flanges, and prestress coupling surfaces on the exterior sides of said flanges, said flanges received in said cavity with said prestress coupling surfaces in engagement with said prestress coupling faces of said prongs, one of said prestress coupling surfaces having indentations in an arc-shaped pattern,
• an operational handle,
• a step round hollow rod at said lower end of said rear-section member,
• adjustment means for connecting said step round hollow rod to said operational handle,
• said operational handle having a hollow cylinder with a base and a link shaft projecting outward from the center of said base of said cylinder,
• said link shaft passing through said step round hollow rod and having an adjustment block connected to its distal end,
• said adjustment block is driven by said adjustment means and is movably received between said interior surfaces of said rear-section member,
• a position audio alarm means for making an audible sound when said rods pivot, in which a protrusion means for restricting the pivoting of said rods on one of said prestress coupling faces of said fore-section member, is received by one of said indentations on said rear-section member, wherein an audible sound is made when said protrusion means moves from one of said indentations to another of said indentations which occurs when the magnitude of the torque applied to the load causes pivoting of said rods.
