发明名称 Method for tightening fastener on axially connected rod-like members
摘要 A method and apparatus for tightening fasteners adapted to combine two bars in a linear fashion. The apparatus includes a first spanner member for engaging a first fastener and a second spanner member for engaging a second fastener. A driving apparatus is provided for rotating the second spanner member and includes a ratchet arrangement and a linear driving apparatus for driving the ratchet arrangement. The first and second spanner members are connected by a separable connection permitting easy separation or assembly. Further, the orientation of the first spanner member is adjustable therefore providing an apparatus which can be applied to and removed from the coupling assembly for two bars in spite of the random rotational orientation of the fasteners.
