[0025] In practical use: Sector teeth 41 are installed on both sides of the back of the fixed plate 2. A transmission rod 43 is rotatably installed on the bottom surface of the mounting base 1 through the bearing seat 42. When the adjusting wheel 45 is shaken, the transmission rod 43 is driven to rotate. A gear 44 is installed on the surface of the transmission rod 43, so that the rotation of the gear 44 drives the meshing sector teeth 41 to move. The sector teeth 41 drive the fixed plate 2 to adjust the angle relative to the hinged mounting base 1, thereby driving the lighting lamps 3 set on both sides of the fixed plate 2 to rotate the angle, which is convenient to adjust the installation angle according to the lighting needs during installation.

[0026] Please see Figure 1 , Figure 3The mounting assembly 5 includes brackets 51 mounted on both sides of the fixed plate 2. An extension arm 52 is mounted on the surface of the bracket 51.

[0028] Please see Figure 4 Mounting block 6 is mounted on the surface of mounting base 1. A lever 7 is rotatably mounted in the middle of mounting block 6. A locking block 8 is mounted on one end of lever 7. The locking block 8 is inserted into the tooth groove on the surface of gear 44. A torsion spring 9 is also sleeved on one end of lever 7. One end of torsion spring 9 contacts the bottom of mounting block 6. An adjustment knob 10 is mounted on the other end of lever 7.

[0029] In practical use: A mounting block 6 is installed on the surface of the mounting base 1. A lever 7 is rotatably installed in the middle of the mounting block 6. A locking block 8 is installed at one end of the lever 7, and an adjustment knob 10 is installed at the other end. When the adjustment knob 10 is rotated, the torsion spring 9 is subjected to force. At this time, when the lever 7 drives the locking block 8 to move away from the tooth groove on the surface of the gear 44, the gear 44 can rotate to drive the sector tooth 41 for adjustment. When the adjustment is completed, the adjustment knob 10 is released, and the torsion spring 9 sleeved on one end of the lever 7 returns to its original position and pushes the locking block 8 to insert into the tooth groove, thereby locking the gear 44 and preventing the gear 44 from rotating.

[0035] In practical use: A rectifier 15 is installed in the middle of the surface of the fixing plate 2. The rectifier 15 is used to convert AC power into DC power to meet the working requirements of the lighting lamp 3.

[0036] Sector teeth 41 are installed on both sides of the back of the fixed plate 2. A transmission rod 43 is rotatably installed on the bottom surface of the mounting base 1 via a bearing seat 42. When the adjusting wheel 45 is rocked, the transmission rod 43 is driven to rotate. A gear 44 is installed on the surface of the transmission rod 43, so that the rotation of the gear 44 drives the meshing sector teeth 41 to move. The sector teeth 41 drive the fixed plate 2 to adjust the angle relative to the hinged mounting base 1, thereby driving the lighting lamps 3 set on both sides of the fixed plate 2 to rotate the angle, which is convenient to adjust the installation angle according to the lighting requirements during installation.
