Principle:Setting:Lift the tubular column according to the needed setting height ,then lower the tubular column ,the wiper block appress the inner wall of casing under the action of spring,when put up the pipe column,the centilizer part of packer and track central pipe engender the relative displacement.Thereby, slip ring pin move along with the track groove of track central pipe,from the top dead center of short slot to the top dead center of elongated slot ,the slips stretch along the conical surface of the cone,fix it on the casing wall .
In the mean time, the setting pin is cut off under the action of regular gravity of pipe column,upper ball joint and track central pipe descend together,compress rubber barrel, so that the diameter of rubber barrel will become larger ,and segregate the annulus space of oil and casing.
Deblocking:lift the tubular column,upper ball joint ascend,the rubber barrel will withdraw the deblocking,slip ring pin move to the bottom dead centre ,the cone body will retreat from slips, slips take back unfreezing.
