ABSTRACT:
A hand-held tool having a motor, a vibration mechanism, and a stake-gripping device is disclosed for driving and extracting stakes or posts. The vibration mechanism generally comprises a housing surrounding a pair of geared eccentric plates or geared weighted plates that are rotated by the motor. The stake-gripping device is attached to the vibration mechanism so that vibrations are transferred into a stake or post through the device housing. Internally, the stake-gripping device comprises a pair of toothed plates with at least one of the plates mounted to the housing utilizing springs. The spring mounted plate has an attached wire connected to a handle. As the handle is grasped, the wire pulls the stake-gripping device into the open position allowing placement of a stake or post into the device. When the handle is released, the toothed plate squeezes the stake or post inside the housing.
