3. Through externally mounted dwang and the guard ring at the outer tube for after object and anticollision ring contact, the dwang can at first contact with the object, can take place to rotate after the dwang receives external force, and then plays the effect of buffering, makes the object be difficult for stopping at the anticollision ring simultaneously, and the rotation of dwang can drive the object and drop downwards, avoids the long-time external pipe of object to extrude. A dwang rotates the back, can drive other teps areas through the drive belt and rotate, and then makes the tep area drive other dwangs and rotate for a dwang atress back, other dwangs can share the impact for it. Other dwangs rotate can make the object can not stop on the outer tube, and the object can fall downwards. And the belt reel can be supported by the supporting rod after being stressed, the belt reel is not easy to deform after being stressed, the position is not easy to change, and the follow-up work can be normally kept. When the belt reel rotates, the ball at the end of the supporting rod rotates in the belt groove in the belt reel, and the supporting rod does not influence the normal rotation of the belt reel.

4. Through at the clean mechanism of inner tube amount internally mounted for when the inside liquid of inner tube flows, produce thrust to the cleaning ring, and then make the inside removal of cleaning ring at the inner tube, the cleaning ring cleans the inner wall of inner tube and scrapes, scrapes the adnexed impurity of inner wall and gets rid of. After receiving the impact force of liquid, a plurality of impeller also rotates thereupon, disperses liquid after the impeller rotates, and then makes the abundant impurity of scraping clean ring of liquid wash, and impurity can be washed away comprehensively. The cleaning ring generates pressure to the spring when receiving the impact force to remove, and the spring shrink, when liquid stops flowing, the cleaning ring receives the impact force to reduce, and the spring promotes clean ring to move back, and further the inner wall to the inner tube is cleared up. The cleaning ring removes the in-process, and inside iron ring produces the inter attraction bonding with the magnet ring for the cleaning ring is to the clean dynamics increase of inner tube inner wall, and the effect of cleaing away is better, makes to produce the cooperation between cleaning ring and the inner circle pipe and uses.
