1. A card reader with a protective mechanism, comprising:
an upper shell, a bottom of the upper shell being opened freely, the upper shell having an inserting passageway longitudinally penetrating through a front end of the upper shell;
a lower shell disposed to a bottom surface of the upper shell to form an accommodating space between the upper shell and the lower shell, the accommodating space being communicated with the inserting passageway;
a protective mechanism disposed between the upper shell and the lower shell, and the protective mechanism being accommodated in the accommodating space, the protective mechanism having:
a front cover having a top wall, a bottom wall, and an isolating wall connected with two inner surfaces of the top wall and the bottom wall, two opposite sides of a rear surface of the isolating wall extending rearward to form two isolating ribs, respectively, two opposite sides of a rear surface of the top wall, two opposite sides of a rear surface of the bottom wall and two inner sides of two rear surfaces of the two isolating ribs being recessed inward to form a plurality of restricting slots, the front cover having a first inserting slot penetrating through a middle of a front surface and a rear surface of the front cover;
a rear cover covered to a rear of the front cover, a middle of the rear cover having a second inserting slot penetrating through a front surface and a rear surface of the rear cover;
two rollers received in the front cover and disposed along an up-down direction;
two springs elastically abutting between two sides of the inner surface of the top wall of the front cover and two opposite sides of one roller along a vertical direction, the two rollers being driven by the two springs along the vertical direction, the one roller abutting against the other roller along the vertical direction to form an abutting position between the two rollers, or the one roller being separated from the other roller along the vertical direction to form an inserting space between the two rollers;
two supporting structures mounted around the two opposite sides of the one roller, and two opposite sides of the other roller; and
a plurality of sealing structures disposed at two outer surfaces of the two supporting structures, the plurality of the sealing structures being fastened in the plurality of the restricting slots, the two rollers, the two springs, the two supporting structures and the plurality of the sealing structures being disposed between the front cover and the rear cover; and
a circuit board assembly disposed between the upper shell and the lower shell, and the circuit board assembly being accommodated in the accommodating space, the protective mechanism being disposed to a front end of the circuit board assembly, the circuit board assembly having a clamping slot penetrating through a middle of a front of the circuit board assembly;
wherein the clamping slot is corresponding to the second inserting slot, the abutting position or the inserting space between the two rollers, the first inserting slot and the inserting passageway.
