[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution: a lamp head that facilitates adjustment of the lighting angle, including a fixing rod 1, a circular plate 2 fixedly connected to the top of the fixing rod 1, two circular plates 2 symmetrically distributed at the top of the fixing rod 1, an adjusting plate 3 slidably connected to the outer surface of the circular plate 2, a fixing plate 4 provided on one side of the adjusting plate 3, a protruding rod 14 fixedly connected to the outer surface of the fixing plate 4, a pull ring 15 fixedly connected to one end of the protruding rod 14, two pull rings 15 in total, and both pull rings 15 need to be pulled simultaneously when adjusting the angle.

[0027] A positioning rod 9 is fixedly connected to the outer surface of the fixed plate 4. A positioning hole 10 is opened on the outer surface of the adjusting plate 3. The outer surface of the positioning rod 9 is slidably connected to the inner wall of the positioning hole 10. Ten positioning rods 9 are provided on the outer surface of the fixed plate 4. The ten positioning rods 9 are evenly distributed and the angle between two positioning rods 9 is thirty-six degrees.

[0028] The outer surface of the circular plate 2 is provided with positioning holes 211. The outer surface of the positioning rod 9 is slidably connected to the inner wall of the positioning holes 211. There are ten positioning holes 211. After the angle is adjusted, when fixing, all ten positioning rods 9 are located inside the positioning holes 211. The position after the angle adjustment must be such that the positioning holes 10 and 21 coincide, so that the adjusting plate 3 and the circular plate 2 can be fixed together. A fixing plate 25 is provided on one side of the fixing plate 14. The lamp head body 6 is fixedly connected to the top of the adjusting plate 3.

[0029] The bottom end of the fixing rod 1 is provided with a mounting hole 16, and the bottom surface of the lamp holder body 6 is fixedly connected with a terminal 17. The terminal 17 is used to connect the wire to supply power to the lamp holder body 6. The mounting hole 16 facilitates the installation of the device.

[0030] A retaining plate 12 is fixedly connected to the outer surface of the adjusting plate 3. A retaining groove 13 is opened inside the circular plate 2. The outer surface of the retaining plate 12 is slidably connected to the inner wall of the retaining groove 13. When the adjusting plate 3 is rotated to change the angle of the lamp head body 6, the retaining plate 12 will slide inside the retaining groove 13. The retaining plate 12 is embedded inside the circular plate 2, so that the adjusting plate 3 and the circular plate 2 will not separate when the lamp head body 6 is rotated.

[0031] One end of the fixed plate 4 is fixedly connected to a telescopic rod 7. One end of the telescopic rod 7 is fixedly connected to the outer surface of the fixed plate 5. A spring 8 is sleeved on the outside of the telescopic rod 7. The fixed plate 4 and the fixed plate 5 are connected together by the spring 8 and the telescopic rod 7.

[0032] One end of the spring 8 is fixedly connected to the outer surface of the fixed plate 4. The telescopic rod 7 cannot automatically extend and retract; it can only extend under external pulling and shorten under external compression. The telescopic rod 7 can keep the spring 8 in a horizontal state and prevent the spring 8 from fatigue bending after repeated use. The other end of the spring 8 is fixedly connected to the outer surface of the fixed plate 5. The spring 8 and the telescopic rod 7 pass through the interior of the adjusting plate 3 and the circular plate 2.

[0033] Working principle: When adjusting the angle of the lamp head body 6, the pull ring 15 pulls the fixing plate 4 and fixing plate 5, increasing the distance between them. At this time, the spring 8 and the telescopic rod 7 extend, pulling the positioning rod 9 on the outer surface of the fixing plate 4 out of the positioning hole 10 and positioning hole 21. Then, the adjusting plate 3 is rotated, and the locking plate 12 slides inside the locking groove 13 to adjust the angle of the lamp head body 6. The adjusting plate 3 is rotated to a suitable position, which requires the positioning hole 10 and positioning hole 21 to coincide. Then, the fixing plate 4 and fixing plate 25 are released, the spring 8 returns to its original position, the telescopic rod 7 shortens, and the positioning rod 9 is inserted into the positioning hole 10 and positioning hole 21, thus restricting the sliding between the adjusting plate 3 and the circular plate 2 and fixing the adjusting plate 3 after the angle is adjusted.
