Abstract

The utility model discloses an extending card, which comprises a body from which a pair of frames is extended, a bottom cover and an upper cover and a lower cover which are correspondingly buckled with each other. Primarily, stepped folding edges which are provided with a plurality of buckling grooves are arranged on both sides of the upper cover. L-shaped folding edges which are provided with buckling sheets which correspond to the buckling groove are arranged on both sides of the lower cover. With the designed structure of the buckling sheets and the buckling groove, when combined with each other, the upper cover and the lower cover can be buckled together more rapidly and tightly, so that the body has more firmness and consequently the extending card can be better assembled.
