Title: Flash drive protection cover

Description:
FIELD OF THE INVENTION 
     The present invention relates to a protective structure of a flash drive to achieve the goal of protecting the flash drive, and more particularly to a protective structure with a decoration cover to provide different designs to increase the practicability. 
     BACKGROUND OF THE INVENTION 
     As technology continues to progress and develop, various electronic devices such as flash drives, mobile phones, MP3, etc. are constantly being introduced, which not only allows users to fully enjoy the fruits of scientific and technological progress, but also significantly enhances work efficiency. Among the electronic devices, flash drives have the advantages of large capacity, fast transmission speed, portable, low cost, convenience and plug to use. Flash drives are widely used in data transmission, however, because the size of the flash drive is usually small and may be lost when carrying it. Also, when the user carries the flash drive, the connecting portion of the flash drive may suffer from collision or abrasion. Furthermore, when the weather or the temperature of the user changes, the flash drive is easy to be moisturized to cause short circuit and reduce the durability thereof. Moreover, the style or design of the flash drive may affect the desire of people to purchase and carry the flash drive, so the flash drive with monotonous design is less desirable and unattractive, and difficult to increase additional value of the flash drive. When considering the life of the flash drive, if the user is tired of the style or design of the flash drive, the user is not able to change the appearance of the flash drive. Thus, there remains a need for a new and improved cover for the flash drive to overcome the problems above. 
     SUMMARY OF THE INVENTION 
     To solve and overcome the problems stated above, the present invention provides a flash drive protection structure including a decoration cover and a protective cover. The decoration cover that is made by elastic materials includes a cover block and a receiving space spacedly. The cover block has a cover hole facing the receiving space, and one end surface of the cover hole forms a guiding surface, and a connecting post is formed inside the receiving space. The protective cover has a first surface and a second surface, and the protective cover is disposed in the receiving space of the decoration cover through the first surface, while the second surface is exposed outside the decoration cover. The protective cover has a connecting hole at the first surface to connect the connecting post of the decoration cover. Also, the protective cover has a receiving trough toward the direction of the cover block, and one end of the flash drive is plugged into the receiving trough, while the other end is plugged into the cover hole of the cover block. 
     The primary objective of the present invention is that the cover block has the cover hole, and the protective cover has the receiving trough corresponding to the cover hole, so that the flash drive can be placed between the cover block and protective cover through the disposition of the cover block and the protective cover. This design can protect the flash drive when it is not in use to avoid collision or abrasion, and to achieve the goal of waterproof, 
     The second objective of the present invention is that the decoration cover is used to wrap the cover block and the protective cover to provide different designs of the protective cover to increase the value of the flash drive and attract more people to purchase. 
     Another objective of the present invention is that the decoration cover has the attaching surface, while the step portion is at the outer surface of the protective cover, and since the engaging strength is increased through the attaching surface and the step portion, the protective cover and the decoration cover would have a smooth contact surface. 
     A further objective of the present invention is that the protective cover is disposed in the receiving space of the decoration cover, and the protective cover partially exposes outside the decoration cover through the second surface, so that the protective cover can be easily detached from the decoration cover to achieve the goal of quick retrieval to increase practicability. 
     Still a further objective of the present invention is that the cover block forms the guiding surface at the cover hole, and when the guiding surface is bended to separate the cover block and the protective cover, the flash drive can evade through the guiding surface so that the flash drive can be easily taken out.
