[0003] In the process of wire insertion in the prior art, the following process is adopted:

[0004] 1. Manually hang the steel wire on the wire insertion pressure roller;

[0005] 2. The device automatically hangs the steel wire on the wire insertion pressure roller in the pulley wire insertion groove;

[0006] 3. The device automatically runs, and at the same time, the lifter motor rotates, the steel wire enters the guide groove from the pulley wire insertion groove, and the process is completed.

[0007] The problems and defects of the prior art are:

[0008] The gap between the steel wire stop point and the edge of the pulley is too small, and in the process of the steel wire entering the guide groove from the pulley wire insertion groove, the steel wire is squeezed by the steel wire stop point and pressed against the edge of the pulley at the intersection of the wire insertion groove and the guide groove, which easily causes the edge of the pulley to crack, resulting in serious defects in product quality.
