BOARD PRESSER TOOL FOR BOARD CARRIER

PROBLEM TO BE SOLVED: To easily attach or detach a board carrier to or from a board carrier and to compactly mount it with one touch, by providing a knob at an upper portion of a metal rod through a hole of the upper surface base of a locking metal fitting, by providing a latch metal fitting at a lower part, and by providing a spring between the upper base and the knob. SOLUTION: A locking metal fitting 22 of a board presser tool 20 is set to the same direction as that of a long hole 19 and is set as if it sits astride on a frame 11 by an outer surface base 24, an upper surface base 25, and an inner surface base 26 of the board presser tool 20. A claw part 27 of the base presses a board 5 from the inner surface base 26, thus preventing the board 5 from being lifted or warped. When a knob 21 of a locking metal fitting is pressed and the locking metal fitting 22 is pressed into the frame 11 and is rotated by 90 degrees, the locking metal fitting 22 is also rotated by 90 degrees. When hands are released from the knob 21, they return due to pressure caused by the retrieval force of a spring 23, the frame 11 is pinched by the locking metal fitting 22 and the upper surface base 25, thus fixing the board presser tool 20.
