Power meter is parallel when falling into, using dipper salvage may card partial-length it is shorter, not firm midway is susceptible to come off again；
Steel wire well testing instrument is most inside to drag for hardly possible realization without latus rectum, and this just makes salvaging cause certain difficulty.
The content of the invention
This utility model provides a kind of short fish head steel wire salvaging instrument, overcomes the deficiency of above-mentioned prior art, its energy
Effectively solving prior art is shorter using the partial-length that dipper salvages card, and not firm midway is susceptible to come off again；Steel
Silk well testing instrument is most without latus rectum, inside drags for the problem that cannot be realized.
The technical solution of the utility model is realized by following measures：A kind of short fish head steel wire salvaging instrument, bag
Top connection, fishing head are included, mandrel, is given up and ring and is dragged for lance, fishing head is sleeved in top connection, and fishing head lower end inside and mandrel are solid
Surely link together, ring of giving up is installed with by the first pin in the lower inside of top connection, ring of giving up is fixedly mounted on
Mandrel upper outside, mandrel lower end and drags for lance and is fixedly installed togather.
The further optimization and/or improvements to foregoing invention technical scheme are presented herein below：
Above-mentioned mandrel outside is provided with spring outer tube, and mandrel middle part outside is installed with spring base, and spring base passes through second
Pin and spring outer tube top are fixedly installed togather, and the inside middle portion of spring outer tube is provided with land, spring base and land it
Between be provided with compression shape compression spring.
Above-mentioned mandrel middle part outside is threadably secured and is provided with spring base.
The above-mentioned lance that drags for is up-narrow and down-wide step cylinder, drag for circumferentially be interval with lance cylinder downward opening axial direction lack
Mouthful.
Above-mentioned fishing head lower inside is fixedly installed togather by screw thread and mandrel upper end.
Above-mentioned mandrel lower end and drag for lance and be threadably secured and be installed together.
This utility model reasonable and compact in structure, it is easy to use, using entering under steel wire, salvaging, reclaim, can grab during salvaging
Firmly threaded upper ends of lost tool, and can lock and realize it is emergent slip out of the hand, this utility model is designed with releasing gadget, is anti-major structure
Subsequent job scheme is reserved into second accident is salvaged, lance has been dragged for and is designed as the elastic pawl type of band, when dragging for lance and dragging for fish fish head has been obtained
Afterwards, the second pin is sheared in downward jarring, and release spring compression stress, spring push the spring outer tube is moved down and is enclosed within and drags on lance, is limited
Drag for lance and be unable to further expansion, it is ensured that the fish head arrested will not fall off.
Description of the drawings
Accompanying drawing 1 is the main view cross section structure diagram of this utility model most preferred embodiment.
Coding in accompanying drawing is respectively：1 is top connection, and 2 is fishing head, and 3 is mandrel, and 4 are ring of giving up, and 5 to drag for lance, and 6 are
First pin, 7 is breach, and 8 is compression spring, and 9 is spring outer tube, and 10 is the second pin, and 11 is spring base, and 12 is land.
Specific embodiment
This utility model is not limited by following embodiments, can according to the technical solution of the utility model and practical situation come
Determine specific embodiment.
In this utility model, for the ease of description, the description of the relative position relation of each part is according to description
The Butut mode of accompanying drawing 1 being described, such as：The position relationship of upper and lower, left and right etc. is according to the Butut of Figure of description 1
Direction is determining.
This utility model is further described with reference to embodiment and accompanying drawing：
As shown in Figure 1, the short fish head steel wire salvaging instrument includes top connection 1, fishing head 2, mandrel 3, gives up and ring 4 and drag for
Lance 5, fishing head 2 is sleeved in top connection 1, and the lower end inside of fishing head 2 and mandrel 3 are fixed together, under top connection 1
Portion inner side is installed with ring 4 of giving up by the first pin 6, and ring 4 of giving up is fixedly mounted on the upper outside of mandrel 3, the lower end of mandrel 3
It is fixedly installed togather with lance 5 is dragged for.When using, with instrument is entered under steel wire this utility model is connected, when this utility model is lowered into
During close Position on the top of the fish, accelerate steel wire lowering velocity, drive this utility model descending by instrument deadweight is entered under steel wire, by fish head
Insertion is dragged in lance 5, is above proposed steel wire, downward jarring salvaging, and directly can above be carried steel wire and rises by this utility model and fish；Reclaim
When if fish is by card, it is high above to carry tension force, can jarring upwards, cut short the first pin 6, top connection 1 is first played out with steel wire, while exposing
Fishing head 2, then dragged at fishing head 2 with Special fishing tool is entered under steel wire, you can jarring upwards is prevented because falling to fish is pulled out
Fish is stuck to cause more complicated second accident.Lance is dragged for using existing known technology.
Above-mentioned short fish head steel wire salvaging instrument can be made further optimization and/or improvements according to actual needs：
As shown in Figure 1, the outside of mandrel 3 is provided with spring outer tube 9, and the middle part of mandrel 3 outside is installed with spring base 11, bullet
