Abstract: A table includes a board, a supporter, a pivot shaft and a lock mechanism. The supporter is disposed on the board. The pivot shaft is disposed on the supporter, and the board is rotatably disposed on the supporter via the pivot shaft. The lock mechanism is disposed between the board and the supporter. The board is switched between a first position and a second position. The lock mechanism fixes the board on the supporter when the board is switched to the first position, and the lock mechanism sets the board parallel to the supporter when the board is switched to the second position.

Abstract: A fixing device includes a first buckling assembly, a second buckling assembly and a pin. The first buckling assembly includes a main body, and a plurality of first holes is formed on the main body. A first arm and a second arm are disposed on the main body. A first fixing component is movably disposed on the first arm. The second arm has a fixing surface. The first fixing component buckles the first object with the fixing surface. The second buckling assembly includes an annular body, and a connecting arm is disposed on an end of the annular body. A second hole is formed on the connecting arm. A second fixing component is movably disposed on the other end of the annular body. The second fixing component buckles the second object with the main body. The pin detachably pierces through one of the first holes and the second hole.
