Preferably, the second sealing body has the same specification and structure as the first sealing body except that the connection spring is attached.
Preferably, the first fixing piece and the second fixing piece have a size smaller than that of the sealing piece, and the first fixing piece and the second fixing piece are fixedly embedded in the sealing piece.
Preferably, a bottom end surface of the second fixed piece in the first sealing body and an upper end surface of the first fixed piece in the second sealing body are fixedly connected by the connecting spring.
Preferably, the first fixing piece and the second fixing piece are both made of metal.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses the gasket has all been installed at first seal and second seal middle part, and first stationary blade and second stationary blade have been installed to the both sides terminal surface of gasket, the bottom face of second stationary blade passes through connecting spring looks fixed connection with the up end of first stationary blade in the second seal in the first seal, first stationary blade and second stationary blade not only play fixed spacing wear-resisting effect in the in-process that the oil blanket used, and be connected through connecting spring between first stationary blade and the second stationary blade in first seal and the second seal, connecting spring makes the oil blanket can corresponding shrink external force disappear back when receiving the extrusion force in the use and recover, the rotation pearl has been installed through first stationary blade and second stationary blade in the outside of first seal and second seal, can make the oil blanket in-process that the use is being rotated to the effectual avoid the rotation axis to cause the oil blanket to receive great frictional force damage and tear the in-process of using through rotating the pearl and tear The oil seal is cracked, so that the service time and the service life of the oil seal are effectively prolonged.
