For reaching above-mentioned innovation and creation purpose, the utility model adopts following technical scheme:

A kind of card reader of rotatable USB plug, comprise housing, circuit switch plate and card reading slot with ccontaining cavity, this circuit switch plate is installed in the ccontaining cavity of housing, this card reading slot and circuit switch plate electrically connect, this housing one end is provided with a rotatable USB plug, this USB plug and circuit switch plate electrically connect, and outside is stretched out in the Plug Division of this USB plug.

The outer columniform pivoted body that coats of described USB plug afterbody, but housing offers the circular pivoted hole of this pivoted body of setting-in relatively, and form between this pivoted body and the pivoted hole rotatable between the crack fit structure.

Be concaved with a ring-type draw-in groove on the described pivoted body, convex with ring frame in the corresponding pivoted hole, this rib is snapped in this draw-in groove.

Tail end at pivoted body is extended with a block, and corresponding is provided with in housing for the movable within it space of block, lives the limited block that block is controlled the USB plug rotational angle but convex with pushing tow in this space.

Described housing is formed by a upper shell and a lower house assembly.

The utility model also comprises a U-shaped decorative panel, and this U-shaped decorative panel is flush-mounted in the recess of offering on the housing outer wall.

Be with a cap that shields on the Plug Division of described USB plug.

Described card reading slot is SD card expansion slot, mmc card expansion slot, CF card expansion slot, SMC card expansion slot or MS card expansion slot.

The utility model beneficial effect compared with prior art is by USB plug and card reader housing are made as pin-jointed structure, make card reader plug computer after, rotatable card reader body adjust the position of body and expansion draw-in groove towards.Thereby effectively avoid card reader to shelter from the USB socket on next door, also insert and take out memory card simultaneously and provide convenience for the user.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

See figures.1.and.2 and show the concrete structure of the utility model one embodiment, as seen from the figure, this card reader comprises a hollow shell 20, the leading flank of housing 20 is provided with three slotted eyes 201,202,203, left end is provided with a USB plug 10, and this USB plug 10 is electrically connected with the circuit switch plate 30 of the ccontaining cavity that is positioned at housing 20 by an electric wire young 50; Stretch out outside the housing 20 Plug Division of USB plug 10, and also be with a cap 40 that is used to protect USB plug 10 on it.

Above-mentioned housing 20 is formed by a upper shell 21 and a lower house 22 assembly, respectively is provided with a recess 21a outside upper shell 21 and the lower house 22 on the surface, and the two recess back that joins becomes U-shaped, and a corresponding U-shaped decorative panel 23 is flush-mounted in this U-shaped recess 21a.Upper shell 21 is formed with a circular pivoted hole 20a with lower house 22 combination backs at housing 20 left ends.

Be provided with a SD card expansion slot 31 and a mmc card expansion slot 32 on foregoing circuit card extender 30 upper sides side by side, downside is provided with a MS card expansion slot 33.These three expansion slot are convenient to SD card, mmc card and MS card and are inserted in its corresponding expansion slot corresponding to three slotted eyes 201,202,203 on the housing leading flank.
