[0037] The detailed installation process of the PCB board for the LED ceiling lamp in this embodiment is as follows: the worker places the board body 1 equipped with the board fixing device 2 under the lamp housing 39, then adjusts the position of the board body 1 so that the board insertion hole 41 is aligned with the board fixing device 2, and then inserts the hole column housing 22 into the board insertion hole 41 until the outer fixing plate hole 42 is aligned with the inner stabilizing column hole 25. Then the worker pulls out the locking pin 38, and then presses the push shaft pressure plate 29 to push the vertical shaft 28 upward until the push shaft pressure plate 2 The top surface of 9 is against the bottom surface of the entry column shell 22. Since the hinge point of the hinge link 31 and the fixed plate column 27 is higher than the hinge point of the hinge link 31 and the hinge platform 30, the hinge link 31 pushes the fixed plate column 27 to slide out of the inner stabilizing column hole 25 and insert it into the outer fixed plate hole 42. At this time, the pin insertion hole 37 is aligned with the upper pin hole 35. The worker passes the locking pin 38 through the upper pin hole 35 and inserts it into the pin insertion hole 37, then the lower locking plate 33 and the vertical shaft 28 are restricted from moving.
