Through the cooperation of the swivel mechanism 2 and the rotating mechanism 29, the first swivel 3 and the second swivel 4 can be rotated in opposite directions. At this time, the lamp holders 7 on both sides of the support column 1 can move up or down at the same time, and the height of the street lamp 28 can be directly adjusted to match the use of different road sections. In addition, with the cooperation of the lamp holder 7, the matching plate 23 and the rectangular frame 18, there is no need for manual support of the street lamp 28, and the street lamp 28 can be installed or disassembled. At the same time, there is no need to use a ladder to replace the street lamp 28, which improves work convenience and reduces the workload of the staff.

[0024] The rotating mechanism 29 includes two side gears 12, which are respectively meshed with the inner gear ring 5 on the inner wall of the first rotating ring 3 and the second rotating ring 4. A driven bevel gear 10 is arranged on the adjacent surfaces of the two side gears 12, and a driving bevel gear 11 is arranged above the driven bevel gear 10. The surface of the driving bevel gear 11 is meshed with the two driven bevel gears 10. A stepping motor 13 is arranged above the driving bevel gear 11. The output end of the stepping motor 13 is connected to the driving bevel gear 11, and the driving bevel gear 11 is driven to rotate by the stepping motor 13. The driving bevel gear 11 can drive the two driven bevel gears 10 to rotate. At this time, the two driven bevel gears 10 rotate in opposite directions, and then under the action of the side gears 12, the first rotating ring 3 and the second rotating ring 4 can rotate in opposite directions. At this time, the lamp holders 7 on both sides of the support column 1 can move up or down at the same time, which can always ensure the balance of the two lamp holders 7, and further improve the efficiency of the staff in replacing the lamps.

[0025] A guide gear 14 is installed in the through hole 9 located above the support column 1. The guide gear 14 is meshed with the inner gear ring 5. Under the action of the guide gear 14, the stability of the first swivel 3 and the second swivel 4 during rotation can be enhanced to ensure their smoothness and safety during operation.

[0026] The lamp holder 7 includes an arc plate 31 and a horizontal plate 32. The arc plate 31 is fixedly installed above the horizontal plate 32. One of the arc plates 31 is connected to the surface of the first rotating ring 3 by bolts, and the other arc plate 31 is connected to the surface of the second rotating ring 4 by bolts, so that the lamp holder 7 and the rotating ring mechanism 2 can be stably connected, further increasing the stability of the device when in use.

[0027] The outer surfaces of the first swivel 3 and the second swivel 4 are both provided with sliding grooves 6, and the inner wall of the arc plate 31 is fixedly provided with a sliding bar 8. The arc plate 31 fixedly connected to the first swivel 3 has the sliding bar 8 on its inner wall slidably installed in the sliding groove 6 on the outer surface of the second swivel 4. Conversely, the arc plate 31 fixedly connected to the second swivel 4 has the sliding bar 8 on its inner wall slidably installed in the sliding groove 6 on the outer surface of the first swivel 3. When the first swivel 3 and the second swivel 4 rotate in opposite directions, the lamp holder 7 can also rotate stably, further ensuring the stability and safety of the lamp holder 7 when in use.

[0028] The lower surface of the transverse plate 32 is provided with a mounting groove 15, and the end surface of the mounting groove 15 is provided with a connecting hole 16. The surface of the mounting groove 15 is fixedly provided with a push strip 17. The matching plate 23 corresponds to the mounting groove 15. The top of the matching plate 23 is provided with a connecting column 24. The surface of the matching plate 23 is penetrated by a through groove 27. The side of the top of the matching plate 23 is fixedly provided with a protruding plate 25. The surface of the rectangular frame 18 is provided with a movable groove 21. A support plate 22 is slidably installed inside the movable groove 21. A contraction groove 19 is provided on the surface of the rectangular frame 18 and below the movable groove 21. A push block 20 is slidably installed in the contraction groove 19. A guide column is fixedly provided at the bottom of the support plate 22. The guide column is movably inserted into the inside of the rectangular frame 18, and the bottom end of the guide column and the surface of the push block 20 are provided with corresponding inclined surfaces. The connecting column 24 is corresponding to the connecting hole 16. The through groove 27, the push strip 17 and the push block 20 correspond to each other, so that the protruding plate 25 can be matched and clamped on the upper surface of the supporting plate 22. When the two lamp holders 7 are rotated downward at the same time, the mounting groove 15 is sleeved on the surface of the matching plate 23. At this time, the push strip 17 is inserted in the through groove 27. As the lamp holder 7 continues to rotate, the push strip 17 can gradually move into the inside of the contraction groove 19, and the push block 20 gradually moves into the depth of the contraction groove 19. The inclined surface at the end of the push block 20 has an extrusion effect on the inclined surface at the bottom of the guide column, so that the guide column will move upward. The supporting plate 22 drives the protruding plate 25 to move upward along the direction of the movable groove 21, so that the overall position of the matching plate 23 moves upward, and the connecting column 24 can be inserted in the connecting hole 16. There is no need for manual support of the street lamp 28 to achieve the installation of the street lamp 28.

[0029] A threaded hole 26 is provided on the middle surface of the mating plate 23, and a positioning bolt 30 is provided on the surface of the cross plate 32. The positioning bolt 30 corresponds to the threaded hole 26. The positioning bolt 30 passes through the cross plate 32 through the surface and is installed in the threaded hole 26, thereby fixing the mating plate 23 and ensuring that the surface of the mating plate 23 can be positioned in the installation groove 15.

[0030] The distance between the end of the transverse plate 32 and the swivel mechanism 2 is the same as the distance between the end of the rectangular frame 18 and the swivel mechanism 2, thereby ensuring that the rectangular frame 18, the transverse plate 32, and the matching plate 23 can be perfectly matched.

[0031] Working principle: First, the surface of the protruding plate 25 is suspended above the supporting plate 22, and then the active bevel gear 11 is driven to rotate by the stepping motor 13. The active bevel gear 11 can drive the two driven bevel gears 10 to rotate. At this time, the two driven bevel gears 10 rotate in opposite directions. Then, under the action of the side gear 12, the first rotating ring 3 and the second rotating ring 4 can rotate in opposite directions. At this time, the lamp holders 7 on both sides of the support column 1 can move up or down at the same time. When the two lamp holders 7 rotate downward at the same time, the mounting groove 15 is sleeved on the surface of the matching plate 23. At this time, The push strip 17 is inserted in the through groove 27. As the lamp holder 7 continues to rotate, the push strip 17 can gradually move into the contraction groove 19, and the push block 20 gradually moves into the depth of the contraction groove 19. The inclined surface at the end of the push block 20 has an extrusion effect on the inclined surface at the bottom of the guide column, so that the guide column will move upward. The support plate 22 drives the protruding plate 25 to move upward along the direction of the movable groove 21, thereby cooperating with the overall position of the plate 23 to move upward. The connecting column 24 can be inserted in the connecting hole 16, and the street lamp 28 can be installed without manual support of the street lamp 28.
