Further, the material of described inverted U-shaped hook and anchor ear is conducting metal.
Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
1, the present invention is supported and is realized being connected of circuit PT and earthing bar by the body of rod, and easy to use, simple, operational risk is low.
2, the present invention arranges resistance wire spiral card, and resistance wire can simply disconnect, according to actual needs quick-replaceable resistance wire.
3, the present invention arranges metal clip and wire spiral card, makes wire more convenient with being connected of earthing bar, anchor ear.
4, the present invention arranges inverted U-shaped hook, can be connected with the tight of circuit PT by implement device, can not damage bus again.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and a specific embodiment, describe.
Referring to Fig. 1.The described portable discharging rod of the present embodiment, comprises the body of rod 1, and the body of rod 1 can select insulation rod to make, and for increasing insulation property, improves fail safe, is provided with insulation grip 7 in the lower end of the body of rod 1.
The body of rod 1 top is fixedly connected with inverted U-shaped hook 2, and this inverted U-shaped hook is made by electric conducting material, as iron.Inverted U-shaped hook 2 inner sides are provided with groove, in inverted U-shaped hook 2, electric wire clip 11 are installed.Electric wire clip 11 consists of two reeds, and two reed Lower Halves are splayed elastic portion, and the two reed first halves are clamping part.The clamping part of reed is arc, is conducive to clamping part and the electric wire interlock of electric wire clip.Meanwhile, the structure setting of this electric wire clip can not cause damage to electric wire.Reed lower end is fixedly connected with inverted U-shaped hook lower end, and reed upper end is fastened in groove, and is slidably matched with groove.Electric wire clip 11 backs are also provided with for improving the clamping part of electric wire clip and the spring leaf 10 of electric wire snap-in force, and one end of spring leaf 10 is fixedly connected with inverted U-shaped hook, and the other end of spring leaf 10 is fixedly connected with reed clamping part back.On inverted U-shaped hook 2, be also provided with resistance wire spiral card, resistance wire end is wrapped on resistance wire spiral card main shaft, and screwing spiral clip can use, and disconnects also very convenient.Can change according to different situations the resistance wire of different resistances.
The bottom of the body of rod 1 is also wound with wire 5, and wire 5 two ends are provided with metal clip 6, and wire 5 one end are connected with anchor ear 3 is detachable, that is to say the wherein metal clip 6 clamping wires spiral cards 9 of one end of wire 5.
Inverted U-shaped hook 2, resistance wire 4, anchor ear 3 and wire 5 are connected successively, form conducting wire, and its effect quite has the electrical discharge wire in conventional art.During use, the terminal board that inverted U-shaped hook clamping need to be discharged, takes the wire being wrapped on the body of rod apart, is connected with earthing bar, can realize the secondary discharge of circuit PT.The present invention is easy and simple to handle, and the end of the hand-held body of rod utilizes inverted U-shaped hook to hang on the secondary earth terminal of circuit PT, has effectively reduced operation easier and risk.While not using, wire is wrapped on the body of rod.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
