A positioning mechanism 4 is provided on the outer side of the clamp seat 1. The positioning mechanism 4 positions the outer side of the support arm 5, thereby adjusting the height of the support arm 5, and thus flexibly adjusting the installation height of the insulator. A distance adjustment mechanism 8 is provided directly above the support arm 5. The distance adjustment mechanism 8 adjusts multiple groups of insulators through a sliding connection seat, thereby improving the high-altitude assembly and positioning of multiple groups of insulators.

[0022] In this embodiment, the positioning mechanism 4 includes a docking slot 2, a fastening hole 3, a support arm 5, a positioning hole 6 and a support plate seat 7. The docking slot 2 is opened on one side of the clamp seat 1, and the fastening hole 3 is opened through the outer side of the clamp seat 1. A support arm 5 is provided on one side of the clamp seat 1, and the top of the support arm 5 is connected to the support plate seat 7. The outer side of the support arm 5 is opened through with positioning holes 6 at equal intervals.

[0023] In this embodiment, the clamp seat 1 is connected to the outer side of the support arm 5 through a docking slot 2 opened on one side. The outer side of the support arm 5 is positioned through the docking slot 2, which facilitates effective adjustment of the height of the support arm 5.

[0024] In this embodiment, the distance adjustment mechanism 8 includes an internal thread seat 9, a metal rod 10, a ceramic skirt 11, an insulating rubber ring 12, a nut 13, a fastener 14, a slide 15 and a guide rod 16. The internal thread seat 9 is installed inside the slide 15, and the inside of the slide 15 is connected to the guide rod 16. The slide 15 is symmetrically opened at the bottom end of the support plate seat 7. The bottom end of the internal thread seat 9 is connected to the metal rod 10, and the outside of the metal rod 10 is connected to the ceramic skirt 11. The outside of the insulating rubber ring 12 is annularly distributed with nuts 13, and the fasteners 14 are distributed in a ring shape on the outside of the clamp seat 1. The metal rod 10 and the internal thread seat 9 are vertically positioned to complete the assembly and positioning of the equipment.

[0025] In this embodiment, the insulating rubber ring 12 is connected to one end of the fastener 14 through a nut 13 provided inside. The insulating rubber ring 12 is used to position the columnar mounting structure, thereby facilitating its insulation positioning.

[0028] Step 1: When installing multiple groups of insulators, first nest the insulating rubber ring 12 and fix it on the power pole. Then, pull the two sides of the clamping base 1 through the notch on one side to fix the clamping base 1 on the outside of the power pole. The operator inserts the fastener 14 into the clamping base 1 so that the other end of the fastener 14 is rotated and locked with the nut 13 inside the nut 13, thereby locking the fastener 14 with the insulating rubber ring 12 set on the other side of the clamping base 1.

[0029] Step 2: Insert the support arm 5 into the outside of the docking slot 2 opened on one side of the clamp seat 1, thereby completing the positioning of the support plate seat 7, and adjust the height of the support plate seat 7 according to the height of the nearby wires to be docked, so that the support arm 5 moves outside the docking slot 2;

[0030] Step 3: Then, insert the bolts into the fastening holes 3 opened on the outside of the clamp seat 1 and the positioning holes 6 opened on the outside of the support arm 5 in sequence, and then lock one end of the bolt by providing a fastening nut 13 on one side of the bolt, thereby achieving the positioning and fastening of the clamp seat 1 and the support arm 5, and then dock the metal rod 10 connected to the outside of the ceramic skirt 11 with the internal thread seat 9, and lock the internal thread seat 9 with the bottom end of the metal rod 10, thereby completing the inverted positioning of the ceramic skirt 11;

[0031] Step 4: Then, according to the diameter of the ceramic skirt 11 and the installation requirements, the internal thread seat 9 is slid on the outside of the slide groove 15, and the spacing of multiple groups of fixed ceramic skirts 11 is adjusted. The internal thread seat 9 is connected through the guide rod 16 set inside the slide groove 15 to ensure the adjustment stability of the internal thread seat 9 and the ceramic skirt 11, and then the internal thread seat 9 and the support plate seat 7 are locked and positioned by inserting screws from the side.
