发明名称 Automatic locking telescopic slide
摘要 A hood prop is adjustable by rotation and without tools. A base rod 33 fits into a hollow friction rod 34 and may be twisted in a first direction to lock in place and in a second opposite direction to loosen for adjustment. A base screw 32 secures a free floating friction piece 31 and a threaded base piece 30 to a threaded base rod 33. The treaded base rod 33 may be inserted into the hollow friction rod 34 and then twisted. The rotation causes the free floating friction piece to press upon the inside wall of the hollow friction rod. The slant surfaces of the free floating friction piece and threaded base piece help move an extended section 40 of the friction piece into the inner wall of the hollow friction rod. The use of two slant surfaces 61 on the threaded base piece 30 facilitates quick response to rotation in either direction.
