Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.

Referring to Fig. 1 Fig. 2, this utility model provides a kind of hydraulic releasing tool, including:

Top connection 1, for hollow tubular structure, if setting 2 is convex stupefied in the axial direction on the cylindrical of lower end, 2 convex stupefied relative axis are symmetrical; Described convex stupefied be discontinuous in the axial direction, formed by some sections.

Shell body 2, for hollow tubular structure, upper end endoporus is arranged and described convex stupefied corresponding groove, and its lower end arranges some location inserting groove; Shell body 2 and top connection 1 are socket-connected and are fixed by some rotation shear pins 3.

Mandrel 4, for hollow tubular structure, is arranged at the lower section of top connection 1, and upper end is connected by screw thread with the lower end of top connection 1;

Baffle ring 6, is arranged in the annular space between shell body 2 and mandrel 4, is axially positioned by the lower section being arranged at baffle ring 6, the positioning retainer ring 7 that is fixed on mandrel 4 cylindrical.

Spring 5, is arranged in the annular space between the lower section of top connection 1, the top of baffle ring 6, mandrel 4 and shell body 2;

Upper positioning sleeve 8, is arranged in the toric space between mandrel 4 and shell body 2;

Lower positioning sleeve 10, is arranged in the toric space between mandrel 4 and shell body 2, the lower section of upper positioning sleeve 8, and by being respectively arranged at the positioning retainer ring 9 above lower positioning sleeve 10, the positioning retainer ring 11 below lower positioning sleeve 10 axially positions;

Flower set 14, is arranged at the lower section of lower positioning sleeve 10, fixes with lower positioning sleeve 10 and is connected; The bottom of flower set 14 arranges some elastic lock claw 142; Flower set 14 lower ends arrange interior cone angle 141.

Fluid cylinder set 13, is arranged in the toric space between mandrel 4 and flower set 14, is connected by shear pin 12 is fixing with mandrel 4;

Lower contact 15, is arranged at the lower section of mandrel 4, flower set 14, is threadably secured with mandrel 4 and is connected; The upper end of lower contact 15 arranges the outside cone angle corresponding with interior cone angle 141, leans to cone angle 141 in when lifting up and described outside cone angle at lower contact 15 and mandrel 4.
