发明名称 Ball puller
摘要 An apparatus for removing the spherical ball from a support shaft in a joint assembly is disclosed. The apparatus includes a housing defining a pair of orthogonally directioned, intersecting channels therein. The channels form a recess well configured to receive a ball to be removed. A drive shaft inserted in a third channel defined in the housing provides a means of applying force to the ball's support shaft, thereby causing the housing to abut against the ball and disengage it from its support shaft mounting.
