Data transmission line capable of reducing interface fracture

The utility model relates to the technical field of data transmission lines, in particular to a data transmission line capable of reducing interface fracture, which comprises a vertical block and a data transmission line, the bottom end of the vertical block is fixedly connected with the data transmission line, the two sides of the inner wall of the vertical block are fixedly connected with supporting blocks, and the top end of the vertical block is fixedly connected with a protective sleeve. The top of the vertical block is slidably connected with a data transmission line, the top end of the data transmission line is connected with an interface, the two sides of the protective sleeve are fixedly connected with a plurality of supporting rods, and a protective structure is arranged on the outer wall of the data transmission line. After use, the interface is pulled out from external equipment, the gear rotates under the influence of the elastic force of the torsional spring, the gear rotates to drive the data t
