[0030] The pressed card plate 33 is adapted to the limiting guide groove 352 through the fixed sliding shaft 32 and then slidably connected to the inside of the fixed card seat 351. The two sets of fixed sliding shafts 32 can be slidably limited inside the fixed card seat 351 through the limiting guide groove 352, which can provide sufficient guiding basis for the subsequent up and down displacement of the pressed card plate 33 on the upper part of the fixed card seat 351.
