description The utility model discloses a coaxial tensioning device which comprises a coaxial positioning assembly, a tensioning assembly, a first driving tensioning assembly and a second driving tensioning assembly. The coaxial positioning assembly comprises an upper positioning cylinder, a lower positioning cylinder and a plurality of screws, and the screws are arranged on the peripheries of the upper positioning cylinder and the lower positioning cylinder and used for locking the upper positioning cylinder and the lower positioning cylinder; the tensioning assembly comprises a plurality of half pieces, and the half pieces are installed between the upper positioning cylinder and the lower positioning cylinder at intervals. The first driving tensioning assembly and the second driving tensioning assembly abut against the inner walls of the two ends of the tensioning assembly correspondingly, and the first driving tensioning assembly and the second driving tensioning assembly can move towards the center of the coaxial pos
