Technical problem for the existence in above-mentioned electric power system, at present, there is a kind of electric armour clamp that can tentatively address the above problem, the structure of this electric armour clamp refers to shown in Fig. 1, specifically comprise the double-screw bolt being connected with insulating bar, the top of double-screw bolt is fixedly connected with U-shaped draw-in groove, and the dual-side of U-shaped draw-in groove is bent downwardly and forms lead-in wire hook.1), U-shaped draw-in groove can realize moving contact of disconnecting link is embedded in U-shaped draw-in groove the effect that this electric armour clamp can reach is:, to prevent that moving contact of disconnecting link from sliding, come off.2), by lead-in wire hook, realize lead-in wire hooked, make lead-in wire can not increase, and then realize the ground clamp hanging on lead-in wire and conveniently take off.
1), adopted between double-screw bolt and U-shaped draw-in groove welding etc. to be fixedly connected with mode but also there is following weak point in above-mentioned electric armour clamp, is in particular in:, this connected mode is easily because of stressed fracture for a long time.2), lead-in wire is hooked in and hooks when lead-in wire, owing to not adopting anti-drop structure how, therefore, when lead-in wire is placed on lead-in wire hook, the phenomenon such as easily occur coming off.
Utility model content
For the technical problem existing in prior art, the purpose of this utility model is to provide a kind of Multifunctional electric metal tool.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of Multifunctional electric metal tool, comprise the double-screw bolt being connected with insulating bar, and the top of double-screw bolt is connected with U-shaped draw-in groove, and the dual-side of described U-shaped draw-in groove is bent downwardly and forms lead-in wire hook; In described double-screw bolt, offer internal thread hole, column spinner bottom screws in the internal thread hole of double-screw bolt, and the bottom end plate face of U-shaped draw-in groove is run through at the top of column spinner, makes U-shaped draw-in groove form by column spinner and double-screw bolt the relation that is rotatably assorted; The end of described lead-in wire hook is provided with hinge, on described hinge, is hinged with back hook, and described time hook is connected with the end elasticity of lead-in wire hook by spring, makes back the horizontal level of end of one end of hook away from hinge higher than the horizontal level of the end of the hook that goes between.
Further, the top of the bottom end plate face of described column spinner in U-shaped draw-in groove is equipped with pad, and the upper surface of the bottom end plate face of described pad and U-shaped draw-in groove is affixed.
Further, the top of described column spinner is equipped with nut.
Further, the end of one end of described time hook away from hinge is also provided with to the non-return card of the flexure plane curving of lead-in wire hook.
Preferably, described non-return card and the angle that returns 35 ° of hook-formings.
Multifunctional electric metal tool of the present utility model, compared with prior art, its beneficial effect shows:
1), Multifunctional electric metal tool of the present utility model, by designing between double-screw bolt and U-shaped draw-in groove, it is the relation of being rotatably assorted, thereby avoided being fixedly connected with mode because having adopted welding to wait between double-screw bolt and U-shaped draw-in groove, and cause because of long-term stressed phenomenon appearance of rupture.Not only can realize moving contact of disconnecting link is embedded in U-shaped draw-in groove, to prevent that moving contact of disconnecting link from sliding, come off, can also improve the useful life of electric armour clamp, and expand the scope of application of electric armour clamp.
2), Multifunctional electric metal tool of the present utility model, end at lead-in wire hook is provided with hinge, on hinge, be hinged with back hook, return hook and be connected with the end elasticity of lead-in wire hook by spring, make back the horizontal level of end of one end of hook away from hinge higher than the horizontal level of the end of the hook that goes between.Not only can realize lead-in wire is hooked, make lead-in wire can not increase, and then the ground clamp that makes to hang on lead-in wire conveniently take off.Can also prevent that the phenomenon coming off from easily appearring in lead-in wire while being placed on lead-in wire hook.
