Pin feature, it is also possible to be other other structures that can axially position.Outer cylinder body 5 can be along cylinder 2
Outer wall move up and down, therefore can increase the height of cylinder 2, and then increase oil field well fishing device 100
The salvaging degree of depth.
Further, as it is shown in figure 1, be positioned at top position and the edge installing through groove 21 on the inwall of cylinder 2
Be axially arranged with the stopper slot 23 of strip, the sidewall of fishing rod 1 is fixedly installed can be in stopper slot 23 on
The limited block 11 of lower movement, limited block 11 is installed on the outer wall of fishing rod 1 removedly, its mounting structure
Can be interface arrangment, or limited block 11 can be fixed on the outer wall of fishing rod 1 and make limited block
11 can be slideably positioned in other structures in stopper slot 23.Cooperation between limited block 11 and stopper slot 23,
Play the slide-and-guide effect of fishing rod 1.Stopper slot 23 is axially disposed strip groove, fishing rod 1
On limited block 11 be slideably positioned in stopper slot 23, it is possible to ensure that fishing rod 1 will not when move up and down
Rotate in a circumferential direction, in order to avoid destroying internal structure and the articulated slab 3 of cylinder 2.
As it is shown in figure 1, in the present embodiment, stopper slot 23 quantity is 2, is radially symmetrical arranged,
Limited block 11 is correspondingly arranged with stopper slot 23.
Further, as shown in Figure 1 and Figure 2, in order to make salvaging claw 4 have a preferable salvaging initial angle,
In a specific embodiment of the present utility model, the numerical value of the first angle α is 120 °.
Further, salvage the dismounting of claw 4 for convenience, salvage claw 4 and be threadingly attached to articulated slab 3
The other end.
Further, as shown in Figure 1 and Figure 2, salvage claw 4 and be provided with the salvaging tooth 41 arranged from bottom to top.
Further, as it is shown in figure 1, the bottom of fishing rod 1 connects the one end having a limit spring 6, spacing bullet
The other end of spring 6 is connected on the base plate of cylinder 2.Limit spring 6 can effectively limit fishing rod 1 relative to
Cylinder 2 move up and down distance, it is to avoid because displacement crosses the structure within havoc cylinder 2, such as avoid
Damage articulated slab 3.
Further, as it is shown in figure 1, the top of fishing rod 1 from bottom to top be provided with inside groove 12, inside groove 12
In can be provided with interior bar 7 movably, the top of interior bar 7 is fixedly installed arm-tie 71.Interior bar 7 can salvaged
The inside groove 12 of bar 1 moves up and down, the outer cylinder body 5 coordinating cylinder 2 upper end to install, whole oil field can be increased
The salvaging degree of depth of down-hole fishing device 100, uses the simplest.In the present embodiment, inside groove 12 He
Being provided with the screw thread being mutually matched on interior bar 7, interior bar 7 can rotate in inside groove 12 and move or decline,
Thus change the salvaging degree of depth of oil field well fishing device 100.
Further, as it is shown in figure 1, on the outer wall of cylinder 2 and at draw-in groove 22 and install between through groove 21
It is provided with the supporting construction 8 for being fixed on shaft in wall by cylinder 2.Supporting construction 8 typically uses existing
Packer or card tile structure, supporting construction 8 can be firmly fixed by the cylinder 2 of oil field well fishing device 100
Being positioned in pit shaft 9, fishing rod 1 moves up and down in the drive articulated slab 3 installation through groove 21 on cylinder 2
Second articulated structure 32 swings, thus drives the salvaging claw 4 of articulated slab 3 other end to swing, and changes and salvages
Angle, salvages article the most easily.
Further, the quantity of supporting construction 8 is two, and two supporting construction 8 intervals are arranged.
When using oil field well fishing device 100 of the present utility model to carry out down-hole article salvaging, first by cylinder
2 and fishing rod 1 assemble, then interior bar 7 and outer cylinder body 5 are assembled and put in place, fishing rod 1 bottom is cut with scissors
Articulated slab 3 hinge mounted connect is in installing through groove 21, and the other end of articulated slab 3 connects salvages claw 4, adjusts
The stretchable height of formation testing field down-hole fishing device about 100 and the salvaging angle of salvaging claw 4, transfer afterwards
Oil field well fishing device 100 is in pit shaft 9.
Before salvaging, first according to the degree of depth salvaged, outer cylinder body 5 is regulated to the height and position required, profit
By manual locking structure (not shown), outer cylinder body 5 is fixed on cylinder 2, interior bar 7 is adjusted to wanting
At the height asked, after the length of good outer cylinder body 5 to be regulated and interior bar 7, by supporting construction 8 by cylinder 2 jail
Fix and be positioned in pit shaft 9.
During salvaging, fishing rod 1 is driven to move up and down by interior bar 7, articulated slab 3 under the drive of fishing rod 1
Swing around the first articulated structure 31, under the leverage of articulated slab 3, salvage claw 4 around the second articulated structure
32 swing, and salvage angle and are changed, and the salvaged claw of down-hole article 4 is salvaged.Salvage claw 4 by down-hole thing
After product are salvaged, down-hole article hang on the salvaging tooth 41 salvaging claw 4, the support on cylinder 2 are tied afterwards
Structure 8 is pulled down from pit shaft 9, is finally brought up from pit shaft 9 by cylinder 2 and can salvage out by down-hole article.
Finally check whether oil field well fishing device 100 has connection to loosen, it is ensured that each structure connects normal, Ji Kejin
Row is salvaged next time.
From the above mentioned, the oil field well fishing device that this utility model provides has the advantages that
1, the claw of salvaging of oil field well fishing device of the present utility model is not fixedly disposed on fishing rod,
But by arranging the cylinder of a tube-in-tube structure outside fishing rod, cylinder arranges installation through groove, passes through
Salvaging claw is hinged on fishing rod by the effect of articulated slab indirectly, the when that such fishing rod moving up and down, just
Can drive under the lever principle effect of articulated slab and salvage claw conversion salvaging angle, such that it is able to more easily
Salvage article；
2, the upper end of the cylinder of oil field well fishing device of the present utility model is additionally provided with outer cylinder body, urceolus
Body is arranged on the upper end of cylinder by fixture block and draw-in groove, can move up and down, and therefore can increase whole cylinder
Height, increase salvage the degree of depth；
3, being additionally provided with an interior bar inside the fishing rod of oil field well fishing device of the present utility model, this is interior
Bar can move up and down in the inside groove of fishing rod, and the outer cylinder body coordinating cylinder upper end to install can increase whole beating
Drag for the salvaging degree of depth of device, use the simplest；
4, the inwall of the cylinder of oil field well fishing device of the present utility model is also equipped with stopper slot, fishing rod
On be provided with the limited block being arranged in stopper slot, so ensure that and do not occur the when that fishing rod moving up and down
