Abstract
The utility model relates to downhole fishing tools, in particular to a multifunctional fishing spear. The technical scheme is as follows: the finishing spear mainly consists of an upper joint, a fishing rod, a saw-toothed external thread and a guide shoe. One end of the fishing rod is connected with the upper joint and the other end thereof is connected with the saw-toothed external thread; and the tail end of the saw-toothed external thread is provided with the conical guide shoe. The multifunctional fishing spear has the benefits of being capable of rotationally bringing out falling objects such as ropes, rubbers and the like through the saw-toothed external thread, being simple in structure and convenient in construction, and saving operation cost.
Description
One, technical field:
The utility model relates to a kind of down-hole fishing tool, particularly a kind of multi-functional fishing spear.
Two, background technology:
Junks such as the interior rope class that exists of existing well, rubber block pit shaft, and the on-the-spot at present lance class instrument that uses can not be realized above-mentioned junk is salvaged, and production and underground work are subjected to very big influence.China's utility model patent number is 200420113592.X " a kind of reversible slide block slips fishing spear ", and its structure is made up of top connection, lance bar, kayser, slips, lock dog, hold-down screw and attachment screw.Because design has latch groove on the lance bar, is connected with kayser on the slips, under hit under the power effect, the latch arm on the kayser can be stuck in the latch groove, thus stationary slip makes it break away from the junk inwall.The problem of its existence is that its structure is complicated for junks such as rope class, rubber, and use cost is higher.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of multi-functional fishing spear of simple in structure, easy construction is provided.
Its technical scheme is: mainly by top connection, drag for bar, zigzag external screw thread and guide shoe and form, an end that drags for bar connects top connection, the other end connects the zigzag external screw thread, the externally threaded end of zigzag is provided with the taper guide shoe.
The beneficial effects of the utility model are: take out of by junks such as class, the rubber rotation of can will restrict by the zigzag external screw thread of rotation the utility model, it is simple in structure, easy construction, saving operating cost.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: top connection (1), drag for bar (2), zigzag external screw thread (3), guide shoe (4).
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Mainly by top connection (1), drag for bar (2), zigzag external screw thread (3) and guide shoe (4) and form, an end that drags for bar (2) connects top connection (1), the other end connects zigzag external screw thread (3), the end of zigzag external screw thread (3) is provided with taper guide shoe (4).
During use, the utility model is dropped into pit shaft, take out of by junks such as class, the rubber rotation of can will restrict by the zigzag external screw thread of rotation the utility model, it is simple in structure, easy construction, saving operating cost.
