Description

Technical Field

[0002] Steel strands are widely used as a common material in power construction. At power construction sites, it is often necessary to bend steel strands that are dozens of meters long. Steel strands have strong toughness and are difficult to bend accurately by hand. Therefore, steel strand bending tooling is needed to assist in bending the steel strands.

[0003] After checking, the publication (announcement) number: CN212121495U discloses a steel strand bender for power lines.

[0004] However, the above-mentioned device performs the bending operation after the stranded wire is firmly fixed to the stranded wire positioning block No. 1.

After the stranded wire is firmly fixed to the stranded wire positioning block No. 1, the bending operation is performed. The fixing process is cumbersome and inconvenient to fix the steel strand, which affects the bending efficiency of the steel strand.

[0005] In order to solve the above problems, a steel strand bending tool is proposed in the present application. Utility Model Content
