[0023] A T-shaped slideway 19 is provided at the lower end of the support plate 7, and a hanging seat 12 is slidably connected inside the T-shaped slideway 19. The front and rear ends of the hanging seat 12 are rotatably connected with pulleys 20. The pulley 20 is located inside the T-shaped slideway 19 and is rollingly connected to the T-shaped slideway 19. Arc seats 21 are fixed at the front and rear ends of the support plate 7. A rolling groove is provided on the surface of the arc seat 21. A roller 22 is rotatably connected inside the rolling groove. One end of the roller 22 protrudes from the notch of the rolling groove.

In this way, after the support plate 7 and the plate sleeve 5 are installed, the end of the lifting rope is tied to the column switch, and the operator pulls the other end of the lifting rope on the ground to pull the column switch to the position above the support plate 7. During this process, the lifting rope rubs against the arc seat 21 or the roller 22, which can reduce friction and increase the service life of the lifting rope. Before pulling, the hanging seat 12 can be slid to move the hanging seat 12 to a suitable position, and the column 3 can be rotated to make the hanging seat 12 face the appropriate direction. In this way, the installation of the auxiliary column switch can be completed even without a crane.

[0024] The upper end of the column 3 is provided with a receiving groove, and a stud 14 is provided inside the column 3. A rectangular rod 25 is fixed to the bottom of the receiving groove. A rectangular channel 23 is opened at the lower end of the stud 14. The upper end of the rectangular rod 25 extends into the rectangular channel 23 and is slidably connected to the rectangular channel 23. The upper end of the column 3 and the outer side of the stud 14 are rotatably connected with a first nut 13, and the first nut 13 is threadedly connected to the stud 14. A high-voltage near-electricity alarm 15 is fixedly installed on the upper end of the stud 14, and a swivel 24 is fixed at the lower end of the first nut 13. The swivel 24 is embedded in the upper end of the column 3 and is movably connected to the column 3. A circle of annular bosses is provided at the outer end of the swivel 24. By setting the high-voltage near-electricity alarm 15, it can be used to sense the induced voltage If the high-voltage line is too close, the high-voltage proximity alarm 4 can promptly send out continuous sound alarm signals to remind the operating personnel of the danger and prevent electric shock casualties caused by illusions and mistakes. By rotating the first nut 13, the first nut 13 drives the swivel 24 to rotate. The setting of the swivel 24 can prevent the first nut 13 from moving vertically, so that the first nut 13 can only rotate. In this way, as the first nut 13 and the stud 14 are threadedly matched, the stud 14 moves up or down along the rectangular rod 25. The setting of the rectangular rod 25 can prevent the stud 14 from rotating, so that the stud 14 can only move vertically, and the stud 14 will drive the high-voltage proximity alarm 15 to move up and down, so that the height of the high-voltage proximity alarm 4 can be conveniently adjusted.

[0025] Working principle: The pole can be clamped by the clamp 1, so that the plate sleeve 5 is installed on the pole, and then the pulley is installed on the suspension seat 12, and then the lifting rope is passed through the pulley of the pulley, and then passed over the top of the support plate 7, so that the lifting rope contacts the arc seats 21 at the front and rear ends of the support plate 7, and then contacts the roller 22, and then the support plate 7 is inserted into the plate sleeve 5, and the first through hole 17 and the second through hole 18 need to be aligned, and then the bolt 8 is inserted into the first through hole 17 in front and through the second through hole 18, and then the end of the bolt 8 passes through the first through hole 17 at the rear, and the bolt can be rotated. 8. After the bolt 8 is threadedly connected and tightened with the second nut 16, the support plate 7 and the plate sleeve 5 can be fixed. Subsequently, the two ends of the connecting arm 10 are respectively placed on the first connecting ear 4 and the second connecting ear 9, and the connecting arm 10 and the first connecting ear 4 and the second connecting ear 9 are fixed with two sets of bolt and nut assemblies 11. After the support plate 7 and the plate sleeve 5 are installed, the end of the lifting rope is tied to the pole switch, and the operator pulls the other end of the lifting rope on the ground to pull the pole switch to the position above the support plate 7. In this way, the installation of the auxiliary pole switch can be completed even without a crane.
