As a kind of preferred version of the present utility model, between the inward flange at differential bottom and housing middle part, two platens are set, encapsulant is arranged between two platens.
As a kind of preferred version of the present utility model, described encapsulant is some sealing rings that stack layer.
As a kind of preferred version of the present utility model, described cylinder barrel shaped housing be take the inward flange at middle part and is divided upper and lower two parts as boundary, and the diameter of upper part is less than the diameter of lower part.
As a kind of preferred version of the present utility model, described differential is the split left and right structure, and left half differential is fluted on the bonding surface at flange place, and right half differential has the projection matched on the bonding surface at flange place.
As a kind of preferred version of the present utility model, on the inner walls of the top and the bottom of slips, be provided with the slips guide strip.
As a kind of preferred version of the present utility model, the rear of described jackscrew is feed rod, is provided with the jackscrew sealing device on the outer wall of housing.
Operating principle of the present utility model:
During normal operation, bolt 7 does not screw, and encapsulant and drilling rod be close contact not, when the water ejection is arranged in boring, at first inwardly twist jackscrew, make slips clamp drilling rod, prevent that drilling rod from ejecting, tight a bolt 7 simultaneously, make encapsulant be close to drilling rod, then open rapidly pipe valve 13, the precipitation drainage, play the anti-spraying effect.
Compared with prior art, the utility model has that the drilling rod of preventing ejects and drain function simultaneously.
