Preferably, being designed with the valve opening structure on each plug, the valve opening structure is spring.
As it is another preferably, the valve opening structure is the jacking block being fixed in outer ring, and the jacking block is the same as the evacuation pit
Centre forms gripping channel, and the jacking block is equipped with introduction bevel along the circumferential both ends of outer ring, and the introduction bevel is the same as outer ring
Form introduction channel between inner peripheral surface, the outer end of the plug are equipped with the drive block cooperated with the jacking block.The driving method is
Rigidity driving will not lead to the problem of fatigue failure for opening compared with above-mentioned spring.
Preferably, the drive block is roller structure, the drive block is contacted by circumferential surface with the jacking block.It can drop
Low abrasion.
Preferably, the intercommunicating pore is linear structure, the intercommunicating pore and extended segment are located along the same line.Production side
Just.
The utility model has an advantage that can go up next root canal road is connected to the rotatory of multiple pipelines.
