     DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION 
     The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. 
     As shown in  FIG. 1 ,  FIG. 2 , and  FIG. 3 , a universal serial bus (USB) cover connecting structure of an electronic product of the present invention comprises a USB port  1  and a USB cover  2  covering the USB port. A USB hole  11  is disposed on a case  10  of the electronic product at a place opposite to the USB port  1 . The USB cover  2  covers the USB hole  11  on the case  110 , and the size and the shape of the USB cover  2  match the size and a shape of the USB hole  11 . The USB cover is made of a soft material. The USB port  1  is fixed on a base  17 , and the base  17  is secured to the case  10  by screws. 
     As shown in  FIG. 2  and  FIG. 3 , the USB port  1  is formed with a flat shape, having a long edge and a short edge. A first extending part  3  and a second extending part  4  are disposed on two ends of the USB cover  2  opposite to the short edges of the USB port  1 , forming a first gap  5  and a second gap  6  between the first extending part  3 , the second extending part  4 , and sidewalls of the USB cover  2 . 
     A protrusion  12  having an annular shape is disposed on the USB hole  11 , and a width of the protrusion  12  on one side of the first extending part  3  is greater than a width of the protrusion  12  on the other side. An end of the USB cover  2  opposite to the protrusion  12  abuts against the protrusion  12 , so that a space is formed between the first gap  5 , the second gap  6 , and the protrusion  12 . 
     While opening the USB cover  2 , the first extending part  3  is pressed by a finger to lift the second extending part  4  up, so that a space allowing insertion of a fingernail is formed between the second extending part  4  and the USB hole  11 , therefore the second extending part  4  is dug out and the USB cover  2  can be entirely removed. Therefore, the USB cover can be designed without considering the position occupied by the groove, so that a more beautiful and complete appearance can be applied. 
     As shown in  FIGS. 2 and 3 , the USB cover  2  may comprise an insertion part  7  for inserting into the USB port  1  and an exterior cover  8  exposed above the case, and the first extending part  3  and the second extending part  4  are disposed on the exterior cover  8 . A groove  9  (shown in  FIG. 4 ) is disposed on a side of the exterior cover  8  opposite to the insertion part  7 , and a side of the insertion part  7  opposite to the exterior cover  8  is inserted into the groove  9  to tightly fit the groove  9 , thereby forming a whole component. A columnar connection rod  13  extending along a direction towards the protrusion  12  is disposed on a side of the insertion part  7  opposite to the first extending part, and a socket  14  is disposed on the protrusion  12  at a position opposite to the columnar connection rod  13  inserting into the socket  14 . A position limiting block  15  with a diameter greater than the socket  14  is disposed on the columnar connection rod  13 , thereby preventing lost and entire removal of the USB cover  2  from the case  10  after being pull out. 
     As shown in  FIG. 5 , the USB cover  2  further comprises a connecting part  16  for inserting into the groove  9  provided between the insertion part  7  and the exterior cover  8 . The connecting part  16  extends towards the first extending part  3  to secure with the columnar connection rod  13 , and the insertion part  7  is secured with the connecting part  16  tightly connecting the groove  9 . 
     As shown in  FIG. 3 , a first hole  18  allowing penetration of the columnar connection rod  13  is disposed at a position of the base  17  opposite to the columnar connection rod  13 , and a second hole  19  connected with the first hole  18  is disposed on the base  17 . An aperture of the second hole  19  is smaller than an aperture of the first hole  18 , and the columnar connection rod  13  is a tapered shape. An end of the largest diameter is connected and fixed to the connecting part  16 , and an end of the smallest diameter of columnar connection rod  13  is inserted into the through hole  18 . Thereafter, because the diameter becomes smaller, an exterior wall of the columnar connection rod  13  and the through hole  18  are tightly connected, thereby preventing the USB cover  2  from falling out of the USB hole  11 . 
     The present invention also provides an electronic product comprising the above USB cover connecting structure of the electronic product. 
     The electronic product of the present invention can be a smart device such as a mobile phone, a smart watch or a smart bracelet. 
     While the invention has been shown and described with respect to the specific embodiments the embodiments of the embodiments of the invention various changes in details.
