Abstract
A push-pull apparatus includes a machine base, and a coupling unit having a retractable main frame disposed on top of the machine base and longitudinally movable in forward and rearward directions relative to the machine base, and a coupler mounted on a front end of the main frame and adapted to be extended into a ring retainer on a wall member to engage a tubular body that is fitted into the ring retainer. An extension unit is mounted on the machine base and is connected to the coupling unit. The extension unit is operable so as to move the coupling unit relative to the machine base. An impact unit is provided on the coupling unit. A drive unit is mounted on the coupling unit and is operable so as to move the impact unit along the coupling unit in order to enable the impact unit to impact a selected one of the front and rear ends of the main frame and generate at the coupler one of a pushing force for assembling the tubular body and a pulling force for disassembling the tubular body.
