摘要：
A drive tool has a tubular drive shaft extending along a first axis with a first end of the shaft defining a connector element including a part-spherical cavity. A second end of the shaft has a drive element. The connector element has walls surrounding the part-spherical cavity, and a pair of slots extending along the walls of the connector element between an outer surface of the connector element and the cavity. A drive element extends along a second axis having a driver tool at a first end and a part-spherical head at a second end, the head pivotally mount in the part-spherical cavity in the connector element. A pair of deflectable arms which engage the part-spherical head are mounted adjacent the cavity of the tubular drive shaft and are deflectable through the slots onto the part-spherical head.
