<p>The power transmission design(60) has a tube (62), a guide piece(84) pushed into it, a retractable rod (64) connected to the guide piece and a catch (88). The guide piece on the rod locks into place on the catch, thereby transmitting the flow of power via the rod, guide piece, catch and tube and along the tube away from its lengthwise axis. The rod is preferably hinged on the catch.</p> |
