When the device advances, the air pump pumps air, so that the inner and outer annular air bags are contracted, the movable plate 15 is positioned at one side of the fixed plate 14, and when the device moves to the working position, the air pump inflates, the inner and outer annular air bags are expanded, so that the movable plate 15 moves to the other side of the fixed plate 14.
Because the inner diameter of the inner annular air bag 32 is smaller than the outer diameter of the rail 16, and the outer diameter of the outer annular air bag 33 is larger than the inner diameter of the cleaning ring 12, when the cover surface 3 is unfolded, the inner and outer annular air bags can be ensured to be tightly attached to the rail 16 and the cleaning ring 12 respectively under the air pressure of the air pump.
Example 3
On the basis of embodiment 2, the cleaning ring 12 and the shaft 13 are provided with annular baffles on one side of the outer annular air bag 33 and one side of the inner annular air bag 32.
Adopt baffle structure, can play the limiting displacement of interior outer annular gasbag after interior outer annular gasbag is aerifyd to avoid the excessive deformation of overlay 3 atress.
