Each strap spring support 190 may extend about 2 mm (approximately 1/16 inch) from the ends of the strap spring 184 at about a 90 degree angle. The positioning slit 180 may have one or more inner wall indentations 188 in a side edge that may receive the strap spring support 190 to hold the strap spring 184 in place.
In one embodiment, rotation of the adjustment knob 154 moves the retractable tooth 172 longitudinally outwardly thus allowing the retractable tooth bit tip 186 to protrude beyond the outer rim 42 for hooking and unhooking wires. The adjustment knob 154 may also be rotated such that the retractable tooth 172 moves longitudinally inwardly, thereby permitting the tool to be used as a safety screwdriver without interference from the retractable tooth bit tip 186.
In one embodiment, a band 200 may be coupled transversely with an outer perimeter of the bit shaft 90 about 19 mm (approximately ¾ inch) from the outer rim 42.
The bit assembly housing 50 may further comprise a first band restricting hollow 202, a band slide hollow 204, a second band restricting hollow 210, and at least one pair of flat head bit guide slots, each pair of flat head bit guide slots having a first bit guide slot 218 and a second bit guide slot 220 on an opposite interior wall of the safety tube 30.
The first band restricting hollow 202 may have a proximal end and a distal end, extend inwardly for a predetermined distance from the outer rim 42, be substantially circular in shape, and have an inner circumference less than an outer circumference of the band 200 and greater than an outer circumference of the flat head screwdriver bit shaft 225. The first band restricting hollow 202 may begin about 17 mm (approximately 11/16 inch) from the outer rim 42 and may extend longitudinally inwardly about 2 mm (approximately 1/16 inch).
The band slide hollow 204 may have a distal end and a proximal end, and extends inwardly from the proximal end of the first band restricting hollow 202 for a predetermined distance. The band slide hollow 204 may begin about 19 mm (approximately ¾ inch) from the outer rim 42 and extend longitudinally inwardly about 11 mm (approximately 7/16 inch). The band slide hollow 204 may have an inner circumference at least as great as the outer circumference of the band 200 so that the band slide hollow 204 is capable of receiving the band 200.
The second band restricting hollow 210 may extend inwardly from the proximal end of the band slide hollow 204, and may be substantially circular in shape. The second band restricting hollow 210 may extend longitudinally inwardly about 17 mm (approximately 11/16 inch). The second band restricting hollow 210 may have an inner circumference less than the outer circumference of the band 200 and greater than the outer circumference of the flat head screwdriver bit shaft 225. Thus, the bit assembly 70 is restricted in movement to an extent that the band 200 is restricted between the first band restricting hollow 202 and the second band restricting hollow 210.
The first bit guide slot 218 and the second bit guide slot 220 extend longitudinally on the safety tube interior walls 36 inwardly from the outer rim 42. The first bit guide slot 218 and the second bit guide slot 220 each has a distal end near the outer rim 42 and a proximal end. The first bit guide slot 218 and the second bit guide slot 220 each has a size and shape complementary to a shape and size of the narrow opposing sides 227 of the flat head screwdriver bit tip 226 such that the proximal end of the first bit guide slot 218 and the proximal end of the second bit guide slot 220 are capable of receiving the narrow opposing sides 227 when the spring element is compressed. The outward extension of the flat head screwdriver bit 228 is limited to the extent that the movement of the band 200 is limited by second band restricting hollow 210, which may restrict extension of the bit element 88 to about 1 mm (approximately 1/32 inch) beyond the outer rim 42. The first bit guide slot 218 and the second bit guide slot 220 each may be about 6 mm (approximately ¼ inch) in length, about 3 mm (approximately ⅛ inch) in width, and about 2 mm (approximately 1/16 inch) deep.
