Adjustable spanner wrench

A new and improved adjustable spanner wrench comprising, in combination:

• a pair of handle halves, the handle halves including a first handle half having an inboard end and an outboard end, the second handle half having an inboard end and an outboard end, the first handle half being provided with an interior channel along its length and an internally threaded axial aperture at its inboard jaws in the form of two C-shaped arms, the C-shaped arms each having an outboard extent with an aperture therethrough for receiving a grooved pin, each C-shaped arm having an inboard extent with an aperture and an associated rivet coupling the outboard ends of the handle halves to the inboard extents of the arms;
• an adjustment link having a first end received in the recess of the first handle half and a second end pivotally secured to the second handle half whereby movement of the first end of the adjustment link will vary the position of the outboard end of the second handle half and one of the C-shaped arms with respect to the other C-shaped arm;
• an adjustment bolt with a threaded exterior surface threadedly received axially in the threaded aperture of the first handle half with an adjustment knob exterior of the first handle half adjacent to the inboard end, the adjustment nut having an outboard end operatively coupled to the first end of the adjustment link to vary its position within the first handle half;
• a pin positionable in each aperture of the outboard extent of each arm, each pin having a groove at one end and a flat axial projection at its other end;
• and
• a pivotable clip having a free end and a pivot end pivotally secured to each outboard C-shaped arm and a semicircular recess at its free end, the semicircular recess adapted to be moved in position concentric with its associated aperture for contacting the groove of the pin received in an aperture.
