[0022] It should be noted that when the utility model is used, the spotlight is fixedly installed at the selected installation position by bolts (a mounting plate for fixing the spotlight is provided on the top of the radiator 1, and a bolt hole is provided on the mounting plate). After the installation is completed, a protective tube cover 2 is fixed to the bottom end of the radiator 1, and a certain distance exists between the bottom of the protective tube cover 2 and the lamp body 3, which is convenient for adjusting the angle of the lamp body 3. When adjusting the angle of the lamp body 3, it is only necessary to press the pressing plate 16, at which time the compression spring 15 is compressed, the slide plate 13 and the clamping hole 18 are both located inside the arc groove 12, and then the connection is rotated. Seat 10, at this time, the lamp body 3 is adjusted to a certain angle along with the connecting seat 10, and the pressure plate 16 can be loosened after adjusting the irradiation angle. When it is necessary to adjust the irradiation in other directions, it is only necessary to push up the connecting plate 11. At this time, the connecting plate 11 pushes the supporting plate 7 to squeeze the supporting spring 6, so that the positioning rod 8 is located inside the fixed tube 5, and then the connecting plate 11 is rotated. The rotation of the connecting plate 11 drives the supporting plate 7 to rotate in the fixed tube 5. After adjustment, loosen the connecting plate 11. At this time, the positioning rod 8 at the bottom of the supporting plate 7 is stuck in the positioning hole 9 at its corresponding position, so that the position of the lamp body 3 is fixed.

[0023] A support spring 6 is fixedly connected to the top of the inner wall of the fixed cylinder 5, and the bottom end inside the fixed cylinder 5 is slidably connected to the support plate 7. The bottom of the support spring 6 is in contact with the support plate 7. A connecting column is fixedly connected to the top of the connecting plate 11, and the end of the connecting column slides into the fixed cylinder 5 and is fixedly connected to the support plate 7.

[0024] It should be noted that the fixing tube 5 is cylindrical in shape, and the supporting plate 7 is disc-shaped. The supporting plate 7 can be lifted, slid, and rotated and adjusted inside the fixing tube 5 .

[0025] The bottom of the support plate 7 is symmetrically fixedly connected with a positioning rod 8 , and the bottom of the fixing tube 5 is located outside the connecting plate 11 and is equidistantly provided with positioning holes 9 , and the positioning rod 8 is slidably inserted into the positioning holes 9 .

[0026] It should be noted that when it is necessary to rotate and adjust the lamp body 3 at a certain angle, it is only necessary to push the connecting plate 11 upwards to make the support plate 7 slide toward the support spring 6 so that the support spring 6 is compressed. At this time, the positioning rod 8 at the bottom of the support plate 7 extends into the fixed tube 5, and then the connecting plate 11 is rotated. After adjusting the irradiation direction of the lamp body 3, the connecting plate 11 is released. At this time, the support spring 6 is reset, and the positioning rod 8 at the bottom of the support plate 7 is re-stuck into the corresponding positioning hole 9, thereby realizing the rotation adjustment of the lamp body 3.

[0027] An arc-shaped groove 12 is provided on the outer side of the connecting plate 11, and sliding holes are provided on the corresponding two side walls of the connecting seat 10, and a sliding rod 14 is slidably connected in the sliding hole. One end of the sliding rod 14 extends into the arc-shaped groove 12 and is fixedly connected to the slide plate 13, and the other end of the sliding rod 14 passes through the connecting seat 10 and is fixedly connected to a pressure plate 16. A compression spring 15 is sleeved on the outer side of the sliding rod 14 and is located between the pressure plate 16 and the connecting seat 10, and the two ends of the compression spring 15 are respectively in contact with the pressure plate 16 and the connecting seat 10.

[0028] It should be noted that when the angle of the lamp body 3 needs to be adjusted, it is only necessary to press the pressure plate 16. At this time, the compression spring 15 is compressed, the slide plate 13 and the clamping hole 18 are both located inside the arc groove 12, and then the connecting seat 10 is rotated. At this time, the lamp body 3 is adjusted to a certain angle along with the connecting seat 10. After adjusting the illumination angle, release the pressure plate 16.

[0029] The bottom end of the protective tube cover 2 is located above the lamp body 3 .

[0030] It should be noted that, by providing the protective tube cover 2, the spotlight can be protected, thereby preventing the top of the lampshade from being damaged and causing light leakage.

[0031] The inner wall of the connecting seat 10 is symmetrically provided with clamping holes 18 equidistantly located outside the rotating shaft. A fixing rod 17 is symmetrically fixedly connected to one side of the sliding plate 13 located inside the connecting seat 10 , and the end of the fixing rod 17 is clamped in the clamping hole 18 .

[0032] It should be noted that the connection between the fixing rod 17 and the clamping hole 18 ensures the stability of the position of the slide plate 13 .

[0033] The length of the arc groove 12 is greater than the sum of the lengths of the slide plate 13 and the clamping hole 18 .

[0034] It should be noted that the length of the arc groove 12 here refers to the distance between the inner wall of the arc groove 12 and the inner wall of the connecting seat 10. When not adjusted, the slide plate 13 is located at the end of the arc groove 12, and the slide plate 13 contacts the inner wall of the connecting seat 10. When adjusting, the pressure plate 16 is pressed to make the slide plate 13 extend into the arc groove 12, so that the fixing rod 17 on the slide plate 13 is disconnected from the card hole 18, and then the slide plate 13 can slide along the arc groove 12 to adjust the angle of the lamp body 3.
