Gear-Drive Adapter with Self-Aligning Catching Mechanism

摘要

A gear-driver adapter configured to switch between at least two gear ratios includes a switch which exerts a force on a drive shaft to move the drive shaft between at least two positions, each corresponding to a gear ratio, in an epicyclic gear system created by a main gear body, ball driver and gear holder with gears. The drive shaft contains keyed structures and, depending on its position within the gear system, the keyed structures on the drive shaft engage or disengage a plurality of key stops. The key stops, in turn, interact with the gears to generate the desired gear ratio. The contours of the keyed structures on the gear holder allow the drive shaft to move between positions without first being specifically positioned. The gear-driver adapter also includes a handle adapter and a driver adapter, allowing users to use any handle or driver with the gear-driver adapter.
