A camming member is reciprocally mounted in each end of the pin to each have a first end thereof engage the tip in bearing contact therewith. A set screw is threadably mounted in the pin to engage a second end of each camming member to urge it into such bearing contact. In a first described embodiment of this invention, the camming member is disposed perpendicular relative to the longitudinal axis of the pin and the set screw is disposed in parallel relationship relative thereto whereas in a second embodiment the camming member and set screw are each disposed at an acute angle relative to the longitudinal axis of the pin.
