[0038] The rear end of the first inner connecting rod 5 is hinged to the inner hinge point of the lamp holder 1, and the front end of the first inner connecting rod 5 is hinged to the inner hinge point of the rear end of the connecting block 2;

[0039] The rear end of the first outer connecting rod 6 is hinged to the outer hinge point of the lamp holder 1, and the front end of the first outer connecting rod 6 is hinged to the outer hinge point of the rear end of the connecting block 2;

[0040] The rear end of the second inner connecting rod 7 is hinged to the inner hinge point of the front end of the connecting block 2, and the front end of the second inner connecting rod 7 is hinged to the inner hinge point of the rear end of the supporting rod 3;

[0041] The rear end of the second outer connecting rod 8 is hinged to the outer hinge point at the front end of the connecting block 2, and the front end of the second outer connecting rod 8 is hinged to the outer hinge point at the rear end of the supporting rod 3;

[0042] The lamp holder 4 is installed on the support rod 3, the lamp holder 4 is in a horizontal position, and the support rod 3 is in a vertical position;

[0043] When the first outer link 6 and / or the second outer link 8 rotates, the first inner link 5 and the second inner link 7 are used to adjust the support rod 3 to maintain a vertical posture.

[0044] It should be noted that the lamp holder 1 includes a base and a rotating seat, the rotating seat can rotate around a vertical axis within a range of 0°-360°, the rotating seat is installed on the base, the rear end of the first inner connecting rod 5 is hinged to the inner hinge point at the top of the rotating seat, and the rear end of the first outer connecting rod 6 is hinged to the outer hinge point at the top of the rotating seat;

[0045] In this embodiment, a first damper 9 is installed inside the first lamp pole, and the first damper 9 is used to apply damping to the first lamp pole rotating around the lamp holder 1 .

[0046] A second damper 10 is installed inside the second lamp pole, and the second damper 10 is used to apply damping to the rotation of the second lamp pole around the connecting block 2 .

[0047] It should be noted that the first damper 9 and the second damper 10 are spring dampers, including a pull rod, a guide rod, a sleeve and a spring, wherein the spring is installed in the sleeve, one end of the guide rod is inserted into the sleeve and connected to the spring, and the other end of the guide rod is located outside the sleeve and is hinged to one end of the pull rod;

[0048] The sleeve of the first damper 9 is the middle section of the first inner connecting rod 5, and the other end of the pull rod of the first damper 9 is hinged to the front end of the first outer connecting rod 6;

[0049] The sleeve of the second damper 10 is the middle section of the second inner connecting rod 7 , and the other end of the pull rod of the second damper 10 is hinged to the rear end of the second outer connecting rod 8 .

[0051] In this embodiment, the bottom surface of the lamp head 4 has a first light source 11 , and the top surface of the lamp head 4 has a second light source 12 .

[0052] The downward lighting of the lamp head 4 adopts a light guide plate structure. Specifically, the first light source 11 is a circle light strip structure, and a light guide plate is arranged above the first light source 11. The light emitted by the first light source 11 is reflected by the light guide plate and irradiated downward, making the downward lighting more uniform and soft, thereby achieving the purpose of anti-glare.

[0059] In this embodiment, the lamp holder 4 and the top end of the branch arm are connected via a damped rotating member 15 .

[0060] It should be noted that the rotating member 15 has a limiting function, so that the lamp holder 4 can only rotate within the range of 0°-90°, thereby avoiding interference between the two lamp holders 4.

[0061] The connection between the lamp holder 4 and the top of the branch arm by the damping rotating member 15 makes the lamp holder 4 rotate more smoothly, avoids sudden swinging, and improves the comfort of use and the safety of the lamp.

[0062] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
