Abstract:
1. A holder for a bit, the bit including a first locking element, comprising: a housing; a base assembly attached to the housing, the base assembly including a first hole and a second hole sized to receive a portion of the bit; a second locking element partially disposed within the first hole and configured to move between a locking position in which the second locking element engages the first locking element to prevent removal of the bit from the second hole of the base assembly, and an unlocking position in which the second locking element is spaced from the first locking element allowing the bit to be removed from the second hole of the base assembly; and a follower assembly contained within the housing and configured to move relative to the housing and base assembly between a first position in which the follower assembly supports the second locking element in the locking position, and a second position in which the follower assembly allows the second locking element to move from the locking position to the unlocking position, wherein the holder is free from structure that is movably attached to at least one of the housing and the base assembly, and that allows the user to move the follower assembly from the first position toward the second position by moving the structure relative to the at least one of the housing and the base assembly, wherein the housing includes a first aperture and a second aperture, the second aperture being opposed to the first aperture, the first and second apertures being configured to provide access to the follower assembly from external the housing, the follower assembly including a first opening and a second opening, the second opening being opposed to the first opening, wherein, when the follower assembly is in the first position, the first opening overlaps with the first aperture and the second opening overlaps with the second aperture such that a passage is formed through the first and second apertures and the first and second openings, and wherein the formed passage is configured to receive an external implement, the external implement allowing a user to move the follower assembly from the first position toward the second position from external the housing by moving the external implement relative to the housing when the external implement is received in the formed passage.
