Mechanism includes runner and is fixed on the tooth that turns on the tubular supporting bar top, on the inwall of the runner and the outer wall for turning tooth
Upper set respectively can intermeshing ridge design；In the step E, the specific method of rotary supporting rod rotating mechanism is：Will
The runner is engaged with each other with the tooth that turns, and rig is connected with the runner, the runner is driven using the rotation of rig
Turn with the tooth spiral that turns.
