Braid connecting device

The invention discloses a braid connecting device which comprises a bottom plate, a nailing assembly and at least four positioning parts, the nailing assembly is arranged on the bottom plate, the axes of the at least four positioning parts are collinear, the at least four positioning parts are arranged on the bottom plate at intervals, the spacing distance between every two adjacent positioning parts is N, the distance between every two adjacent positioning holes in a braid material is M, and M is larger than or equal to 1. N = xM; wherein x is an integer greater than zero, so that the positioning piece can be inserted into the positioning hole of the braid material, the upper braid material and the lower braid material can be aligned in the length direction, size deviation caused by front-back inconsistency is avoided, and the braid material is accurately positioned; a section of blank braid can be formed before a box of braid material is formally used and after the material is used, the braid connecting dev
