ABSTRACT:
The present invention is a method and device for a hand power tool which includes a housing, a storage compartment within the housing, a wrench for manipulating a collet bit attachment structure, a portion of the wrench sized to fit within the storage compartment, a first spring extending into the storage cavity and positioned to bias the portion of the wrench against an inner wall of the storage compartment and a protuberance positioned on the housing, such that when the portion of the wrench is partially within the cavity, the protuberance causes a first misalignment between the longitudinal axis of the storage compartment and the longitudinal axis of the wrench and when the portion of the wrench is fully within the cavity, the protuberance does not cause a misalignment between the longitudinal axis of the storage compartment and the longitudinal axis of the wrench as large as the first misalignment.
