A first blade is fixedly coupled to the distal end of the shaft to prevent motion in a proximal direction and a plunger is at least partially located within the hollow interior portion of the shaft and slidable therein between an extended position and a retracted position. A compression member exerts force on the plunger in a distal direction and a second blade is mechanically coupled to the plunger so that, when the plunger is in the extended position, the first blade and second blade extend approximately equidistant from the distal end of the shaft and form a substantially perpendicular configuration with one another and when the plunger is in the retracted position, the first blade extends a greater distance from the distal end of the shaft than does the second blade. | 09-27-2012 |
| 20130263706 | MULTI FORM SCREW DRIVER AND SCREW DRIVER BIT - Multi form screw driver and screw driver bit that fits on any screw head configuration and contains springs, a rubbery unit and micro-bit needles where the spring pushes the rubbery unit to form a tighter fit of the micro-bit-needles on the top surface of the screw such that the screw does not retract when pressure is applied. | 10-10-2013 |
| 20160121464 | ANTI-DISENGAGEMENT STRUCTURE OF A TOOL HEAD FOR A FASTENER - An anti-disengagement structure of a tool head for insertion into an insertion recess of a fastener is provided. Abutting faces extend from a periphery of an end face of a working portion. At least one abutting face is partly formed with a groove filled with an elastic member which is partly protrusive out of the groove and beyond the surface of the abutting face. The largest extent between the protruded-out part of the elastic member and the abutting face of another elastic member is larger then the largest inner extent of the insertion recess. Thereby, with the stretchable characteristic of the elastic member, the fastener can be smoothly inserted into the insertion recess and abutted against an inner surface of the insertion recess to achieve anti-disengagement effect. | 05-05-2016 |
