Patent ID: 7617959

Claim:
An adjusting device for a nail gun comprising a magazine having a base disc; a shaft being mounted centrally through the base disc and having an outer surface; a proximal end being mounted rotatably through the base disc and protruding from the inner surface of the base disc; a distal end; two positioning slots being respectively defined longitudinally in the shaft, diametrically and parallelly to each other; two sliding grooves being respectively defined longitudinally in the shaft, diametrically and parallelly to each other and each having a distal opening; and multiple pairs of positioning recesses, each pair of positioning recesses being defined diametrically in the shaft respectively along one of the slide grooves and each positioning recess being an inverted wedge, the inverted wedge having a base being disposed toward the disc base; an apex being aligned centrally on a corresponding sliding groove and having a guide incline; and a depth being greater at the base than the apex; a disc feeder being mounted around the shaft and comprising a sleeve being mounted around the shaft and having a distal end; a proximal end; an inner surface; two mounting holes being respectively defined through the sleeve and each selectively corresponding to one of the positioning recesses; a mounting groove being defined around the proximal end of the sleeve and through the mounting holes; two guiding grooves being respectively defined longitudinally and diametrically in the inner surface of the sleeve and corresponding respectively to the sliding grooves in the shaft; and two wedging holes being respectively defined through the sleeve and communicating respectively with the guiding grooves; and a rotating disc being formed on and protruding radially from the proximal end of the sleeve; and a positioning assembly being mounted between the shaft and the sleeve and comprising a clamp having a button being mounted in the distal end of the sleeve and having an outer surface protruding from the top end of the sleeve; and an inner surface; and two clamping arms being formed on and protruding from the inner surface of the button, being respectively mounted slidably in the guiding grooves in the sleeve and in the sliding grooves in the shaft and each clamping arm having a distal end; an outer surface; a sliding incline being defined at the distal end of the clamping arm and being disposed adjacent to a corresponding mounting hole in the sleeve; and a boss being formed on the outer surface of the clamping arm and being mounted in a corresponding wedging hole in the sleeve; and an E-clip being mounted in the mounting groove in the sleeve and having two stops being mounted respectively in the mounting holes in the sleeve and each having an inner end having a push incline formed thereon and abutting the sliding incline of a corresponding clamping arm.
