On the basis of technique scheme, following further technical scheme can be had:
Described antiseepage case is two semicircular cylinder cases be mutually fastened and connected, the upper end of each cylinder case is equipped with semi-circular joint pin, described pivot flange is arranged on semi-circular joint pin upper end, and two semicircular cylinder case locking engagement sleeves are connected in described plug-in strip rotating shaft by one group of sunk screw by two semi-circular joint pins.
The bottom of described bearing fixed mount is at least provided with the sealing ring be sealed and matched with switch blade mechanism case outer container end face together.
Described antiseepage encloser inner wall is connected sealing ring, is coordinated between described antiseepage case with described plug-in strip rotating shaft by seal ring seal.
Described rotating part is plane bearing, and a plane and the described antiseepage case of plane bearing are connected, and another plane and the described bearing fixed mount of plane bearing are connected.
The described part that holds out against is supporting bolt, nut.
Beneficial effect of the present invention: this apparatus structure is closely reasonable, and easy for installation, sturdy and durable, not easily season cracking, seal is good especially, and anti-seepage effect is good.
