Like this, will be convenient to articulating and breaking away from of first hook and angle steel.
As preferably, first hook is best to be formed by the steel plate bending,
First connecting portion that can be operatively connected with the live line working action bars on the last anchoring jig or a kind of mouth of hook second hook or a kind of annulus down.
Like this, the bar head of live line working action bars rhampotheca is easily gone in this hook or the annulus, realizes far-end operation.
As preferably, first connecting portion of this annular preferably is positioned at the top of first hook.
Like this, with the lifting that hangs of more convenient entire belt charged renewal device.
As preferably, second hook preferably is installed in the back side of first hook back-to-back.
As preferably, also be provided with a kind of second connecting portion that is connected with wire grip on the last anchoring jig.
This second connecting portion can be positioned at the center section part of anchoring jig, also can be positioned at the bottom of anchoring jig, as preferably, preferably is positioned at the bottom of anchoring jig.
Second connecting portion can be a kind of bolt clamp device, and bolt is horizontally through corresponding hole, anchoring jig lower end and wire grip upper end and realizes going up being connected of anchoring jig and wire grip.
The wire grip spanner is positioned at the below of anchoring jig.
The wire grip pinch bar is provided with a kind of the 3rd connecting portion that can be operatively connected with the live line working action bars.
The 3rd connecting portion can be a kind of crotch, also can be a kind of annulus, as preferably, and preferably a kind of annulus.
Like this, the bar head of live line working action bars rhampotheca is easily gone in this crotch or the annulus, realizes that far-end operation is to pull handle.
Wire grip hypomere portion is connected with insulated tension pole by a kind of the 4th connecting portion.
The 4th connecting portion can be a kind of ratchet device, can also be a kind of screw connection, and the 4th connecting portion is horizontally through corresponding hole, wire grip lower end and insulated tension pole upper end by a bolt and realizes being connected of wire grip and insulated tension pole.
Be intervally distributed with cross-perforating on the insulated tension pole along its length, following suspension hook is realized and being fastenedly connected of insulated tension pole by the securing member of cross-under in this cross-perforating.
Therefore the adjustable insulated tension pole of this adjustable full employment length can, only need once the insulator string that thoroughly does away with the replaceable different sheet numbers of edge pull bar in response to the link position of suspension hook and insulated tension pole under the insulator string adjustment of different length.
In sum, the present invention has following advantage compared to existing technology: but the charged for replacement insulator string, operation simultaneously is simpler again, just can implement with existing operating habit and operative skill, and compact conformation is simply transformed and can be used existing instrument.
