[0037] In this embodiment, a docking sleeve 32 is sleeved on the outer side of the docking joint 19, an operating rod 33 is welded to the lower end of the docking sleeve 32, and an operating handle 34 is welded to the lower end of the operating rod 33. The docking sleeve 32 can be quickly installed and separated from the docking joint 19, and can be used for operation during adjustment operations and removed when not in use.

[0038] In this embodiment, the docking structure 26 includes a lifting connection block 27, a docking protrusion 28, a splitting block 29 and an expansion block 30. The lifting connection block 27 is welded to the lower end of the lifting mounting plate 31. The docking protrusion 28 is integrally formed at the front and rear of the outer side of the lifting connection block 27. The two splitting blocks 29 are movably installed on the upper inner side of the docking protrusion 28. The expansion block 30 is integrally formed below the splitting block 29. The lifting connection block 27 is used to connect and fix the sleeve 23.

[0039] In this embodiment, the docking protrusion 28 is connected to the interior of the fixed sleeve 23, the expansion block 30 is located inside the docking protrusion 28 and is movably connected thereto, the expansion block 30 is arranged in a triangular shape, and the two expansion blocks 30 are arranged symmetrically. Through the triangular setting of the expansion block 30, the expansion head 16 can push the two expansion blocks 30 to separate.

[0040] In this embodiment, the bottom of the docking clamp 25 rotates around the torsion spring shaft seat 24, the top of the docking clamp 25 is sleeved on the outside of the docking protrusion 28, the splitting block 29 is tightly connected to the top of the docking clamp 25, and the torsion spring shaft seat 24 drives the docking clamp 25 to always flip to one side through the setting of the torsion spring, so that the docking clamp 25 is firmly stuck on the outside of the docking protrusion 28 for fixation, and can also be pushed open for separation.

[0041] It should be noted that the present invention is an energy-saving lighting device that is easy to hoist. When in use, the hoisting installation plate 31 is first installed on the top of the wall through screws for fixing, the fixed sleeve 23 and the hoisting connection block 27 are first separated, and then the upper end of the fixed sleeve 23 is connected to the hoisting connection block 27, and at the same time, the docking clamps 25 on both sides are sleeved on the outside of the docking protrusion 28, and the torsion spring shaft seat 24 drives the docking clamp 25 to always apply force to one side, so that the docking clamp 25 is firmly connected to the docking protrusion 28, the fixed sleeve 23 and the hoisting connection block 27 are installed and fixed, and then the lower components are hoisted, and then the lamp wick 8 in the top lampshade 6 is energized for light illumination;

[0042] When the lighting angle of the device needs to be adjusted, the docking sleeve 32 at the upper end of the operating rod 33 is docked with the docking joint 19. Therefore, by rotating the operating handle 34 and the operating rod 33, the docking sleeve 32 and the docking joint 19 can be driven to rotate. The rotation of the docking joint 19 simultaneously drives the lifting drive rod 18 and the gear mounting block 20 at the upper end to rotate. Affected by gravity, the gear mounting block 20 is first located at the bottom, so that the driving gear 21 at the bottom is meshed and connected with the bottom transmission gear 10. Therefore, the rotation of the gear mounting block 20 also drives the bottom transmission gear 10 through the driving gear 21. The teeth 10 rotate, and the bottom transmission teeth 10 then drive the worm teeth 9 to rotate, and the meshing connection between the worm teeth 9 and the worm wheel teeth 3 drives them to rotate, thereby driving the gear connecting frame 4 and the lamp connecting rod 5 outside the worm wheel teeth 3 to rotate, and adjusting the lighting angle of the lower wick 8. The worm teeth 9 and the worm wheel teeth 3 are a connection structure of worm gears. After the worm teeth 9 drive the worm wheel teeth 3, the lead angle of the worm teeth 9 is less than the equivalent friction angle of the meshing worm wheel teeth 3, and reverse self-locking can be achieved. The worm wheel teeth 3 cannot drive the worm teeth 9 to rotate to position the adjusted angle of the wick 8.

[0043] When the lighting height of the device needs to be adjusted, after the docking sleeve 32 is docked with the docking head 19, the operating handle 34 is grasped and moved upward, so that the lifting drive rod 18 rises upward in the fixed mounting plate 1 and the worm gear 9, thereby moving the gear mounting block 20 to the top, and then the upper driving gear 21 is meshed and connected with the top transmission gear 15. Therefore, when the operating rod 33 and the lifting drive rod 18 rotate again, the driving gear 21 is used to drive the top transmission gear 15 to rotate, and the top transmission gear 15 drives the lifting screw 14 to rotate in the support ring 13, and then the lifting screw 14 is connected with the thread in the fixed sleeve 23, so that the lifting screw 14 rotates up and down to adjust the lighting height of the lower wick 8;

[0044] When the device needs to be dismantled, the lifting screw 14 is continuously rotated upward so that the lifting screw 14 rotates to the top of the fixed sleeve 23, so that the expansion head 16 enters the docking protrusion 28 and contacts the center of the two expansion blocks 30, and the conical structure of the expansion head 16 is used to push the two triangular expansion blocks 30 to expand and move, thereby driving the two split blocks 29 to expand, so that the split block 29 pushes the docking clamp 25 to move to the outside of the docking protrusion 28, thereby separating the docking clamp 25 from the docking protrusion 28, and the fixed sleeve 23 can be quickly disassembled from the lifting connection block 27 to dismantle the device.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
