It is slided outside inner tube and is cased with setting of casing, the cased side wall is equipped with through-hole identical with one diameter of through-hole described in said inner tube
Two, two inner wall of through-hole is equipped with screw thread and position and one face of through-hole, the interior sliding of the through-hole one are equipped with connecting pin, institute
The diameter for stating connecting pin is identical as the internal diameter of the through-hole one, and the connecting pin protrudes into the length in the through-hole two and protruded into not
Greater than the depth of the displacement casing upper groove, it is screwed with silk plug on the outside of the through-hole two, between the silk plug and the connecting pin
Equipped with connecting spring, one end of the connecting spring is fixedly connected on the silk plug, said inner tube and the displacement casing it
Between and said inner tube and the setting of casing between be installed with several sealing rings.
A word groove is equipped on the outside of the silk plug.
The sealing ring uses NBR nitrile rubber sealing ring.
The connecting pin is spherical shape.
The utility model has the beneficial effects that：When needing well workover, the steel ball of the utility model is put into upper casing simultaneously
Give in casing certain hydraulic, setting of casing can get rid of the constraint of connecting pin to be detached from inner tube, without using cutting
The mode of oil pipe reduces technical staff's amount of labour, and reduces the consumption of material and the energy, reduces costs.

It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown, a kind of hydraulic releasing tool, including releasing tool main body and steel ball 11, the releasing tool main body packet
Casing 1 is included, upper 1 bottom interior wall of casing is equipped with screw thread, and the steel ball 11 is located in the upper casing 1, the upper casing 1
Bottom set is screwed with inner tube 2, and 2 on both sides of the middle of said inner tube is equipped with through-hole one, and 2 top and bottom inner wall of said inner tube is installed with
Cricoid spacing collar 3, sliding sleeve is equipped with displacement casing 4 in said inner tube 2, the outer wall of the displacement casing 4 be equipped with it is described interior
The identical groove of one diameter of through-hole on pipe 2,4 bottom of displacement casing is installed with casing spring 5, described sleeve pipe spring 5
It is fixedly connected with the spacing collar 3 of 2 bottom of said inner tube, described sleeve pipe spring 5 when compressing on the displacement casing 4 completely
Through-hole face on groove and said inner tube 2, said inner tube 2 are slided be cased with setting of casing 6 outside, and the side wall of the setting of casing 6 is equipped with
Through-hole two identical with one diameter of through-hole described in said inner tube 2, two inner wall of through-hole is equipped with screw thread and position leads to described
One face of hole, the interior sliding of the through-hole one are equipped with connecting pin 7, and the diameter of the connecting pin 7 is identical as the internal diameter of the through-hole one,
