[0036] Further, such as Figure 4 As shown, a ball is provided on the side of the No. 1 blocking piece 82 away from the No. 2 blocking piece 85 to facilitate the movement of the adjustment assembly 8.

[0037] Further, such as Figure 1 and Figure 4 As shown, a wire 86 is provided inside the T-slot, one end of the wire 86 passes through the pull rod 83 and is connected to the lighting lamp 7, a switch is provided inside the support tube 21, the switch passes through the support tube 21 and extends to the outside of the support tube 21, the other end of the wire 86 passes through the arc rod 4, the adjustment tube 22 and the inside of the support tube 21 in turn and is connected to the switch, and the switch is connected to the power supply through the wire.

[0038] Further, such as Figure 1 As shown, a main light is installed in the middle of the bottom end of the connecting column 54.

[0039] The use process of the adjustable lighting device provided by the utility model is as follows:

[0040] When in use, the exhibit is placed under the main light, and several lights 7 provide supplementary light for the exhibit from different angles. The main light box light 7 is turned on and off by the switch. When the height of the adjusting tube 22 needs to be adjusted, the screw cap 32 is turned to drive the screw rod 33 to rotate through the rotating rod 31, so that the screw rod 33 moves away from the inside of the supporting tube 21, and the force of the rubber pad 36 squeezing the adjusting tube 22 is reduced. Then, the adjusting tube 22 is moved by hand to adjust the height of the adjusting tube 22. When the adjusting tube 22 needs to be fixed, the screw cap 32 is turned in the opposite direction, so that the screw rod 33 moves toward the inside of the supporting tube 21, and the screw rod 33 pushes the spring 36 to move the adjusting tube 22. The sheet 35 causes the rubber pad 36 to squeeze the adjustment tube 22, and the friction between the rubber pad 36 and the adjustment tube 22 limits the adjustment tube 22. When the horizontal illumination angle of the lighting lamp 7 needs to be adjusted, when the lamp holder 6 needs to be rotated, the lamp holder 6 is lifted upward, and the lamp holder 6 drives the connecting column 54 to move upward, and the No. 2 limiting tooth is separated from the No. 1 limiting tooth 52. The lamp holder 6 or the connecting column 54 is rotated to make the limiting plate 53 rotate inside the mounting tube 51 to achieve the angle adjustment of the lamp holder 6. When the rotation of the lamp holder 6 needs to be limited, the lamp holder 6 is released to make the limiting plate 53 fall, and the No. 2 limiting tooth is meshed with the No. 1 limiting tooth 52 to limit the rotation of the lamp holder 6.

[0041] When it is necessary to adjust the vertical illumination angle of the lighting lamp 7, pull the lampshade 81 in the direction away from the lamp holder 6, the lampshade 81 is separated from the lamp holder 6 and no longer contacts, the second baffle 85 is also separated from the inner wall of the T-slot, and then move the lampshade 81. When it is necessary to fix it, release the lampshade 81, and the elastic force of the compression spring 84 pushes the second baffle 85. The second baffle 85 squeezes the inner wall of the T-slot and the lampshade 81 squeezes the lamp holder 6, thereby fixing the adjustment component 8, and then adjusting the position of the lighting lamp 7. When adjusting the vertical illumination angle of the lighting lamp 7, the exhibits can have better lighting adjustment during the display process.
