摘要:
A driver including a handle, lever, swivel cap, shaft, and a tip mechanically connected to the lever configured to engage a screw. Engaging the lever causes the tip to either compress or expand so as to lock the screw to the driver. According to one exemplary embodiment, the cap can be translated releasing the lever, thereby releasing the screw from the tip. According to one embodiment, the cap is a swivel cap allowing for jeweler style use. Advantages of the present system and method, according to various embodiments, include a tip compressing a feature that is within an outer diameter of the screw allowing a driver, or a portion thereof, to have a maximum diameter equal to or smaller than the maximum diameter of a screw.
