Attachable surface cover for USB port

1. An attachable surface cover for a USB port, comprising:

a casing with an attachment component, and

a base plate detachably connected to the attachment component,

wherein the casing is configured to be attached to a piece of cloth by means of the attachment component penetrating through the cloth,

wherein the attachable surface cover has a plug hole configured for insertion and removal of a USB cable, wherein an entrance of the plug hole is on the casing, and wherein an exit of the plug hole is used to configure a USB port.

2. The attachable surface cover for a USB port according to claim 1 , wherein the casing comprises a substrate that is attachable to the cloth, wherein the attachment component is formed on the substrate, and several first friction bulges are formed in a protruding manner on a side surface of the substrate on which the attachment component is provided, and wherein when the attachment component penetrates through the cloth and then is mounted on the base plate, the first friction bulges abut against the cloth.

3. The attachable surface cover for a USB port according to claim 2 , wherein a cross-sectional area of the plug hole is gradually reduced in a direction in which the USB cable is inserted in the plug hole.

4. The attachable surface cover for a USB port according to claim 3 , wherein the attachment component comprises first attachment pins formed on the substrate, and wherein when the attachment component penetrates through the cloth, the first attachment pins pass through a first through hole in the cloth.

5. The attachable surface cover for a USB port according to claim 4 , wherein the casing further comprises a base, which is formed in a protruding manner on a side surface of the substrate facing away from the attachment component, wherein the casing is provided with a third through hole, and the base plate is provided with a fourth through hole used to configure a USB port; and wherein when the attachment component penetrates through the cloth and is then mounted on the base plate, the third through hole is in communication with the fourth through hole to form the plug hole.

6. The attachable surface cover for a USB port according to claim 5 , wherein the third through hole is arranged obliquely.

7. The attachable surface cover for a USB port according to claim 1 , wherein several second friction bulges are formed in a protruding manner on the base plate, and wherein when the attachment component penetrates through the cloth and then is mounted on the base plate, the second friction bulges abut against the cloth.

8. The attachable surface cover for a USB port according to claim 5 , wherein first stop members are formed in a protruding manner inside the fourth through hole, wherein each of the first attachment pins comprises a connector connected to the substrate and a second stop member provided on the connector, and wherein when the attachment component penetrates through the cloth and then is mounted on the base plate, the base plate is clamped between the substrate and the second stop members, and the connectors are supported on the first stop members.

9. The attachable surface cover for a USB port according to claim 3 , wherein the attachment component further comprises a second attachment pin formed on the substrate, and wherein when the attachment component penetrates through the cloth, the second attachment pin passes through a second through hole in the cloth.
