Stud connecting structure

The utility model relates to a stud connecting structure which comprises a first part and a second part, wherein threaded holes are respectively formed in the first part and the second part, and the first part is connected with the second part through the threaded holes and a stud body. The stud connecting structure is characterized in that threads are arranged at the two ends of the stud body, and the thread pitch of the threads at one end of the stud body is larger than the thread pitch of the threads at the other end of the stud body. A through hole communicated with a threaded hole of the first part is formed in the bottom of the threaded hole of the first part. According to the stud connecting structure, gradual fixing of the two parts in interference fit with each other can be guaranteed in assembling, and also gradual separation of the two parts in interference fit with each other can be guaranteed in dismounting.
