The principle of above-mentioned handle device are as follows: after screw extractor pierces the threaded fastener blocked, staff will be held
The interconnecting piece that the fixed link of handle device protrudes into screw extractor is open and is pierced by, and the second handle cover is in fixed link, staff
Both hands hold respectively the first lever and the second lever by screw extractor and the threaded fastener that blocks from screw hole it is artificial to the left
Rotation is taken out or is extracted.
A kind of and matching used electric drill of screw extractor, comprising: electric drill ontology and drill bit interconnecting piece；
The drill bit interconnecting piece is equipped with 2 lug bosses corresponding with the sleeve openings.
Above-mentioned electric drill is cooperated with screw extractor, and lug boss is stuck in sleeve openings when drill bit interconnecting piece protrudes into sleeve,
To drive screw extractor to be rotated by lug boss.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The utility model has the advantage of the structure of screw extractor is simple, is readily produced and regular job, is suitble to work
Needed for personnel's Daily Level Readiness.

Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent actual product
Size；
To those skilled in the art, it is to be understood that certain known features and its explanation, which may be omitted, in attached drawing
's.
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
A kind of screw extractor, as shown in Figure 1, comprising: extractor ontology 1, interconnecting piece 2 and casing；
Extractor ontology 1 is equipped with screw thread；
Interconnecting piece 2 is equipped with perforative opening 21；
Extractor ontology 1, connecting tube and sleeve 3 are fixedly connected sequentially.
In the present embodiment, the screw thread of extractor is left hand thread.
In the present embodiment, casing is hollow metal sleeve.
In the present embodiment, extractor ontology 1 is cemented carbide member, and interconnecting piece 2 is metal parts, and interconnecting piece 2 is equipped with
The opening 21 extended transversely through.
In the present embodiment, extractor ontology 1, connecting tube and sleeve 3 successively welding fabrication.
In the present embodiment, the one end opposite with interconnecting piece 2 of sleeve 3 is equipped with axisymmetric 2 sleeve openings 31.
A kind of and matching used handle device of screw extractor, as shown in Figure 2, comprising: the first lever 41, fixed link 5
With the second lever 42；
First lever 41 is fixedly connected with fixed link 5, and the second lever 42 is detachably connected with fixed link 5.
A kind of and matching used electric drill of screw extractor, as shown in Figure 3, comprising: electric drill ontology 6 and drill bit interconnecting piece 7；
Drill bit interconnecting piece 7 is equipped with 2 lug bosses corresponding with sleeve openings 31.
The application method of screw extractor is described below:
