On set there are three the guide groove and three arc grooves concentric with external gear with limiting slot cooperation, pin shaft one is across guide groove and cunning
Block is fixedly connected, and pin shaft two is equipped in arc groove, two both ends of pin shaft are fixedly connected with two housings respectively.
Further, the self-locking wire clamp bottom is equipped with movable bulb, is equipped with ball groove at the top of insulating bar, movable bulb passes through
Locking nut is connect with ball groove.
Further, the pedestal, which is equipped with, may be reversed universal wheel, and turnable universal wheel includes shaft, and shaft passes through bottom
Seat, shaft bottom are equipped with the universal wheel being fixedly connected.
Further, the insulating bar is telescopic bar.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model solves high-voltage connection general instead of original common wire clamp by the self-locking wire clamp with string holes
Shaking and the caducous problem of high-voltage connection in logical wire clamp；
2, self-locking wire clamp makes sliding block under guide groove and limiting slot effect, Automatic-clamping high pressure is drawn by rotation external gear
Line, it is easy to use, and limited and stucked by pawl, high reliablity, substantially increase the safety of the utility model；
3, it after turnable universal wheel is determined in the utility model position, is flipped up by shaft, pedestal is made to land comprehensively,
It is more firm, avoid insulating bar from shaking.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, high-potting insulating support, including pedestal 4 and insulating bar 3, insulating bar 3 can stretch up and down, institute
It states and is equipped with self-locking wire clamp 1 at the top of insulating bar 3.
As shown in Figures 4 to 7, the self-locking wire clamp 1 includes two shells 8 matched, is equipped with external tooth between two housings 8
12 are taken turns, lead entrance is respectively equipped on shell 8 and gear 12, external gear 12 is limited by pawl 15, and pawl 15 is hinged on shell 8
On, spring 16 is equipped between pawl 15 and shell 8；It is respectively equipped with concentric string holes 9 on shell 8 and external gear 12, is set on shell 8
There are three equally distributed limiting slot 10, it is equipped with sliding block 11 in limiting slot 10, sets that there are three match with limiting slot 10 on external gear 12
The guide groove 14 of conjunction and three arc grooves 13 concentric with external gear 12, pin shaft 1 pass through guide groove 14 and the fixed company of sliding block 11
It connects, pin shaft 2 18 is equipped in arc groove 13,2 18 both ends of pin shaft are fixedly connected with two housings 8 respectively.
