In this embodiment, the fixing mechanism 6 includes two embodiments of clamping the bypass cable joint and/or limiting the bypass cable.
In the present embodiment, the fixing mechanism 6 includes a return spring 61; the return spring 61 is located in the insulating sheath 5, one end of the return spring 61 is fixedly connected with the conductive column 4, and the other end of the return spring is fixedly connected with the insulating sheath 5.
In this embodiment, an annular insulating block 62 is fixedly connected to one end of the insulating sheath 5 close to the conductive connection seat 3.
When the bypass cable access device works, the bypass cable access device in the prior art is complex in structure and inconvenient to operate; when the joint of the bypass cable is connected with the binding post of the quick access device, a hanging mode is usually adopted, but the hanging mode is not suitable for the windy weather, and the wind blows the bypass cable to cause the bypass cable to shake, so that the joint of the joint and the binding post to shake, and the bypass circuit is influenced to supply power;
therefore, before using the invention, a worker firstly surveys the site, lays the cable damp-proof cloth, arranges the bypass cables at two ends of the power grid cable to be overhauled, then connects the bypass cables to connect the bypass cables with the load switch for transmitting power, then the worker takes the lift truck to reach the position of the invention on the high-voltage telegraph pole, then the worker inserts the insulating rod into the round hole on the insulating sheath 5, the worker holds the insulating rod with both hands and stirs the insulating rod outwards, so that the insulating sheath 5 moves outwards, the reset spring 61 is compressed, the other worker hangs the joint of the bypass cable on the conductive post 4, then the worker holding the insulating rod draws out the insulating rod from the round hole on the insulating sheath 5, so that the insulating sheath 5 moves backwards under the action of the reset spring 61 and clamps the joint of the bypass cable together with the conductive connecting seat 3, the annular insulating block 62 increases the degree of contact of the insulating sheath 5 with the bypass cable; the staff puts the bypass cable into the power supply after returning to the ground, so that the current enters the power grid cable through the bypass cable, the conductive column 4 and the conductive connecting seat 3, and then the staff disconnects the power grid cable to be overhauled from other power grid cables, so that the power grid cable is overhauled or maintained under the condition of no power failure; the worker pulls the insulating sheath 5 again after the power grid circuit is overhauled, then takes the joint of the bypass cable off the conductive post 4, and then pulls out the insulating rod from the insulating sheath 5, so that the insulating sheath 5 returns to the original position under the action of the reset spring 61 and sleeves the conductive post 4, and the insulating effect on the conductive post 4 is achieved;
when the conductive column 4 needs to be grounded, the grounding cable is grounded firstly, and then the grounding cable is communicated with the conductive column 4 by the method;
according to the invention, after the joint of the bypass cable is connected with the conductive post 4, the insulating sheath 5 clamps the joint of the bypass cable under the action of the reset spring 61, so that the shaking of the joint of the bypass cable is reduced, the influence of the shaking of the joint on power transmission and the generation of surge are reduced, and meanwhile, the shaking of the joint of the bypass cable is reduced, so that the friction between the conductive post 4 and the joint of the bypass cable can be reduced, the protection time of a tinned layer on the surface of the conductive post 4 on internal red copper is prolonged, and the service life of the conductive post 4 is prolonged.
In this embodiment, the conductive posts 4 are symmetrically provided with sliding grooves 7; the insulating sheath 5 is connected with the sliding groove 7 in a sliding manner through the sliding block 71, and a gap is reserved between the insulating sheath 5 and the conductive column 4.
When a worker pokes the insulating sheath 5 through the insulating rod, the insulating sheath 5 pulls the sliding block 71, so that the sliding block 71 slides in the sliding groove 7, the insulating sheath 5 is not in contact with the outer surface of the conductive post 4 due to the arrangement of the sliding block 71, and when the worker moves the insulating sheath 5, the insulating sheath 5 does not rub the outer surface of the conductive post 4, so that the abrasion of a tin coating on the outer surface of the conductive post 4 is reduced, and the red copper part of the conductive post 4 is prevented from being oxidized and corroded by air after the tin coating is abraded, and the power connection effect is influenced; meanwhile, the sliding block 71 can also limit the insulating sheath 5 to prevent the insulating sheath 5 from rotating, so that the circular hole at the tail end of the insulating sheath 5 is inclined, and a worker cannot conveniently insert the insulating rod into the circular hole; moreover, the air part between the insulating sheath 5 and the conductive column 4 has an insulating effect, so that the insulating effect of the insulating sheath 5 is enhanced.

In this embodiment, the insulating sheath 5 is fixedly connected with a tetrahedral block 74; one of the edges of the four-sided block 74 is disposed away from the conductive connection holder 3.
In northwest areas, due to more wind sand and dust, the dust adheres to the surface of the conductive post 4, and the conduction between the bypass cable and the conductive post 4 is affected; when workers in northwest areas pull the insulating sheath 5 slowly, the insulating sheath 5 compresses the return spring 61, so that the return spring 61 drives the soft brush 72 to move, the soft brush 72 brushes the surface of the conductive post 4, dust on the surface of the conductive post 4 is brushed away, and the dust falls to the lower part in the insulating sheath 5; after the power grid circuit is overhauled, a worker pulls the insulating sheath 5 again and takes off the joint of the bypass cable, then the insulating rod is pulled out from the insulating sheath 5, in the process of resetting of the insulating sheath 5, air between the insulating sheath 5 and the piston block 73 is extruded and blown out from the notch on the piston block 73, so that dust falling in the insulating sheath 5 is blown out of the insulating sheath 5 by blown air, the blown air can be guided to two sides of the sliding block 71 by the inclined surfaces on the four-face blocks 74, the sliding block 71 is prevented from blocking, the dust in the air is prevented from sinking, meanwhile, two ends of the sliding block 71 are arranged in an inclined shape, the dust in front of the sliding block 71 can be scooped up when the sliding block 71 moves, the dust in the sliding groove 7 is prevented from being accumulated in front of the sliding block 71 to influence the movement of the sliding block 71, and the practical use effect of the invention is improved.
