发明名称 Drill gripping device and method
摘要 A drill gripping device is shown with an inexpensive and compact design. In one embodiment, an inexpensive and more compact design is possible through the use of a single actuator with a single gripping portion of a drill gripping device. Embodiments of drill gripping devices shown are further reduced in price and size due to a force amplification device such as a camming arm. Alternatively, an increased gripping force is possible using an existing size actuator. A drill gripping device is shown with increased precision in gripping. A pair of gripping jaws are synchronized to improve jaw centering capabilities.
