Description
Technical field
The utility model relates to a kind of movable data storage device, is specifically related to a kind of USB flash disk.
Background technology
Along with scientific and technological development, computer become people handle official business the life in requisite instrument, USB flash disk also is widely used as a kind of movably memory device.But because the volume of USB flash disk is little, be easy to lose, lost USB flash disk and can lose heap file, thereby affect people's work, to people, bring a lot of inconvenience.
In prior art, the problem of easily losing for solving USB flash disk, make brooch, bangle, pendant etc. by USB flash disk, is easy to carry.For example Chinese utility model patent CN202396118U discloses a kind of USB flash disk bangle.This USB flash disk bangle comprises bangle body, USB flash disk, on described bangle body, draw-in groove is housed, buckle is equipped with at the draw-in groove rear portion, USB flash disk is housed in draw-in groove, cap bag is equipped with at the USB flash disk top, and bales catch is equipped with on the cap bag top, and snap close is equipped with on bangle body right side, draw-in groove and buckle bales catch are integral to be made, and is easy to carry and has prevented the USB flash disk loss.Yet people often can forget and extract the USB flash disk that inserts USB interface.While particularly using on the machine in public, forget that USB flash disk may cause the serious consequences such as leakage of data.Technique scheme can not address this problem.Therefore, need to be improved the structure of existing USB flash disk, can prevent from that people from forgetting to pull up USB flash disk.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of USB flash disk, by structural improvement, can prevent from that people from forgetting to pull up USB flash disk.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of USB flash disk, comprise USB flash disk memory body, described USB flash disk memory body comprises housing, is arranged at the USB interface of housing one end and is arranged at memory circuit and the control circuit in housing, also comprise scalable coil and a collar, described housing is provided with a junction, described scalable coil one end connects the connecting portion on housing, the other end connects the described collar, and the girth of the described collar is greater than the girth of user's wrist portion.
In technique scheme, the described collar consists of the helical form coiling.
In technique scheme, the described collar consists of elastica.
In technique scheme, the described collar is the annular solid with opening.
In technique scheme, described USB flash disk memory is existing structure, connects a telescopic coil on USB flash disk memory body, and the other end of described coil connects a telescopic collar.USB flash disk in use, is enclosed within the collar on hand, after USB flash disk insertion computer carries out transfer of data, when the people will leave, will find to be enclosed within the collar on hand, in time USB flash disk is pulled up.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is by flexible coil is set on the USB flash disk body, at the other end of flexible coil, the flexible collar is set, and the described collar is enclosed within on wrist, and after USB flash disk inserts computer, thereby just can find when the people will leave that the collar on wrist is avoided forgetting pulls up USB flash disk.
