## Abstract

A card fixation assembly for a card holder, including: a main body, a first elastic arm, a second elastic arm, a first clamping end, and a second clamping end. A first elastic arm start end and a second elastic arm start end are connected to the main body; a first elastic arm tail end is connected to the first clamping end; and a second elastic arm tail end is connected to the second clamping end. The first clamping end includes a first protrusion; the second clamping end includes a second protrusion; and the first second protrusions are configured to limit displacement of a card, such that the card is not separated from the card fixation assembly naturally. The card can be easily and conveniently stored and taken, and the displacement of the card is still firmly restricted after long-time use.

## Claims

### Claim 1

A card fixation assembly for a card holder, comprising: a main body, a first elastic arm, a second elastic arm, a first clamping end, and a second clamping end, wherein a first elastic arm start end and a second elastic arm start end are connected to the main body; a first elastic arm tail end is connected to the first clamping end; a second elastic arm tail end is connected to the second clamping end;
the first clamping end comprises a first protrusion; the second clamping end comprises a second protrusion; the first protrusion and the second protrusion are configured to limit displacement of a card; the first protrusion comprises a first concave surface and a first convex surface; the first concave surface is matched with an arc of the card; the first convex surface is adjacent to the first concave surface, and is located at a tail end of the first protrusion; the second protrusion comprises a second concave surface and a second convex surface; the second concave surface is matched with the arc of the card; and the second convex surface is adjacent to the second concave surface, and is located at a tail end of the second protrusion.

### Claim 2 (depends on 1)
