Abstract:
1. A board fixing module, comprising: a base body having a first fixing hole formed therein; a fixing element embedded into the first fixing hole of the base body, the fixing element having a stop board extending around the periphery of the top of the fixing element for preventing the fixing element from passing through and dropping out of the first fixing hole; a board having a second fixing hole formed therein, the board abutting the base body such that the first and second fixing holes are aligned and the stop board is disposed between the base body and the board; a latch element having a bottom portion passing through the second fixing hole of the board for latching to the fixing element; and a passing rod passing into the latch element to cause the latch element to latch with the fixing element for securing the board to the base body, wherein the middle of the fixing element has a latch hole, the length of the latch element is greater than the length of the fixing element, the latch element is passed through the latch hole, and the middle of the latch element has a through hole axially penetrating the latch element, wherein the bottom portion of the latch element has an external diameter greater than a diameter of the latch hole of the fixing element, and after an elastically retractable claw-shaped latch portion of the latch element is passed through the latch hole, the claw-shaped latch portion is situated below the fixing element, and an internal wall around the periphery of the through hole has an internal flange disposed on the claw-shaped latch portion, wherein the passing rod is passed into the through hole of the latch element, and a bottom portion of the passing rod has a protruding lump disposed at an external edge and propped at the internal flange for restricting the claw-shaped latch portion from being retracted in a latched condition, and the length of the passing rod is greater than the depth of the through hole, such that when the passing rod is pressed such that the protruding lump is situated below the internal flange, the claw-shaped latch portion is elastically retracted to release the latched condition of the latch element and the fixing element.
