An embodiment of the present invention discloses a rotatable data card, which belongs to the field of communications. The rotatable data card includes a data card body (1), a USB connector (2), and a rotating shaft assembly (3). The rotating shaft assembly (3) includes a rotating shaft (31), a fixed fluted disk (32), and a rotating shaft casing (33). The rotating shaft (31) and the fixed fluted disk (32) are accommodated in the rotating shaft casing (33). Teeth are set on the rotating shaft (31) and the fixed fluted disk (32), and the rotating shaft (31) and the fixed fluted disk (32) are engaged with each other. The USB connector (2) includes a bracket (21), where a hole (22) is opened on the bracket (21). The rotating shaft casing (33) is fixed in the hole (22). The rotating shaft (31) is fixedly connected to the data card body (1). The rotating shaft (31) rotates relative to the fixed fluted disk (32), and an angle between the data card body (1) and the USB connector (2) is never 180 degrees. In the present invention, when the data card body is rotated, a case that the data card body is perpendicular to the direction of gravity is avoided, and a relatively good heat dissipation effect is achieved. |
