Referring to FIG. 3: further, the diameters of the receiving groove 702 and the limiting groove 704 are the same as the diameter of the lower pressing plate 402, the central angle corresponding to the fan-shaped receiving groove 702 is 60 degrees, and the central angle corresponding to the fan-shaped limiting groove 704 is 30 degrees. The lower pressing plate 402 and the upper pressing plate 408 can be limited by the accommodating groove 702 and the limiting groove 704, and the angle setting of the accommodating groove 702 and the limiting groove 704 does not influence the sliding of the lower pressing plate 402 and the upper pressing plate 408 in the sliding groove 703, so that the positions of the lower pressing plate 402 and the upper pressing plate 408 are changed.

When the installation mechanism of the LED lamp is used, firstly, the LED lamp 8 is installed inside the LED inner lamp shell 5, the LED lamp 8 is supported through the limiting ring 601 and is preliminarily limited, then the connecting ring 604 arranged at one end of the limiting frame 603 is connected with the connecting groove 602, the limiting frame 603 is rotated to be installed on the LED inner lamp shell 5, the size of the inner ring of the limiting frame 603 is set, after the limiting frame 603 is installed, the limiting frame 603 presses the upper end of the LED lamp 8 to be determined firstly, so that the LED lamp 8 is limited inside the LED inner lamp shell 5, after the LED lamp 8 is installed and fixed, the LED down lamp is assembled, before the LED down lamp is installed, the joint of the LED lamp 8 is connected with a circuit arranged in a ceiling, the LED outer lamp shell 1 is installed inside a mounting groove formed in the ceiling, then the inner wall of the LED lamp 8 is pressed to rotate and synchronously drive the LED inner lamp shell 5 to rotate, two groups of bumps 701 arranged on the outer side of the LED inner lamp shell 5 move in the groove 2 arranged on the LED outer lamp shell 1, the lower pressing plate 402 and the upper pressing plate 408 move out of the containing groove 702 in the rotating process of the LED inner lamp shell 5, the limited sliding is carried out by the sliding groove 703, the lower pressing plate 402 and the upper pressing plate 408 finally fall into the limiting groove 704, at the moment, the bumps 701 arranged on the outer side of the LED inner lamp shell 5 move to one end in the groove 2, the positions of the lower pressing plate 402 and the upper pressing plate 408 are fixed, the lower pressing plate 402 and the upper pressing plate 408 move out of the clamping groove 3 arranged on the LED outer lamp shell 1, at the moment, after the lower pressing plate 402 rotates under the external force, the position of the connecting shaft 404 can be changed, and further the first spring 406 arranged between the shaft sleeve 405 and the connecting shaft 404 is in a stretching state, because the lower pressing plate 402 and the upper pressing plate 408 are connected through the second spring 407, the first through hole arranged on the lower connecting sleeve 403 arranged on one side, the lower pressing plate 402 can slide up and down and also can deflect at a certain angle, the second through hole arranged on the upper connecting sleeve 409 enables the upper pressing plate 408 to only slide up and down, and then after the lower pressing plate 402 and the upper pressing plate 408 are moved out of the clamping groove 3, one end of the lower pressing plate 402 is under the action of the second spring 407, the lower pressing plate 402 tilts at a certain angle on the fixed shaft 401 through the lower connecting sleeve 403, the lower pressing plate 402 is in contact with the inner wall of the ceiling, the LED down lamp is installed in the installation groove arranged on the ceiling through the two groups of lower pressing plates 402, the installation of the LED down lamp is completed, when the LED down lamp is disassembled, the LED lamp 8 is reversely rotated to synchronously drive the LED inner lamp shell 5 to rotate, so that the lower pressing plate 402 is reset under the action of the first spring 406, the lower pressing plate 402 and the upper pressing plate slide back to the accommodating groove 702 in the sliding groove 703 of 408, and further the lower pressing plate 402 and the upper pressing plate are, the LED down lamp is convenient to disassemble.
