    • An adjustment device comprises a first portion and a second portion. The first and second portions are adjustably engaging one another. The adjustment device has an overall length that is adapted to be adjusted by adjusting the first and second portions relative to one another. The overall length is adapted to be adjusted to vary a distance between the drill motor and the work piece. Another embodiment of the invention comprises a slip fit member and a threaded member opposite the slip fit member. The adjustment device has an overall length that is adjustable to vary a spatial relation between the drill motor and work piece. Yet another embodiment of the invention comprises a drill motor, a support, and an adjustment device. The adjustment device comprises a slip fit member and a threaded member spaced apart from the slip fit member. One of the members is engageable with the drill motor and the other member is engageable with the support. The adjustment device has an overall length that is adjustable to vary the spatial relation between the drill motor and the support.
    • 调节装置包括第一部分和第二部分。 第一和第二部分可调节地彼此接合。 调整装置具有适于通过相对于彼此调节第一和第二部分来调整的总长度。 整个长度被调整以改变钻机马达和工件之间的距离。 本发明的另一个实施例包括滑动配合构件和与滑动配合构件相对的螺纹构件。 调节装置具有可调整的整体长度以改变钻机电机和工件之间的空间关系。 本发明的另一个实施例包括钻头电机,支撑件和调节装置。 调节装置包括滑动配合构件和与滑动配合构件间隔开的螺纹构件。 其中一个构件可与钻机马达接合,另一个构件可与支撑件接合。 调整装置具有整体长度,其可调节以改变钻机电机和支撑件之间的空间关系。
