Embodiment Construction

[0026] Such as figure 1 with figure 2 As shown, this torsion threading tool is used for binding ropes such as iron wires, and it is composed of a handle body 1, a pull bar 2, a guide 4 and a spring 3 and the like.

[0027] The handle body 1 is cylindrical, and the pull rod 2 is rod-shaped.

[0028] A connection sleeve 9 is threadedly connected to the port of the handle body 1 , and the connection sleeve 9 is sleeved on the pull rod 2 . A cylindrical guide 4 is also set on the pull rod 2, and a spring 3 is also set on the pull rod 2. The two ends of the spring 3 are pressed against the inner end of the pull rod 2 and the guide 4 respectively, and the The guide piece 4 abuts against the connecting sleeve 9 under the action of elastic force.

[0029] Such as image 3 with Figure 4 As shown, the end of the guide 4 has a ratchet 7, and the end of the connecting sleeve 9 has a ratchet 2 8, and under the elastic force of the spring 3, the ratchet 7 of the guide 4 and the ratch...

Abstract

The invention provides a torsion wire fastening tool, which belongs to the machinery technical field and solves the problems that manual steel wire tying in the prior art is low in working efficiency, etc. The torsion wire fastening tool comprises a handle body in a cylindrical shape and a pull rod in a rod shape, wherein the inner end of the pull rod is positioned inside the handle body; the outer end of the pull rod protrudes from the handle body and is provided with a connecting structure; the pull rod is sleeved with a guide piece and a spring; two ends of the spring respectively act on the inner end of the pull rod and the guide piece; the guide piece pushes against the handle body under the elasticity action of the spring, and a one-way mechanism capable of allowing the guide piece to rotate in a single direction is arranged between the handle body and the guide piece; the outer side of the pull rod is provided with a spiral guide structure, and the guide piece is inlayed in the guide structure. The tool can ensure that the pull rod rotates continuously only in a single direction in a to-and-fro expanding-contracting process by pulling the handle body to and fro. The torsion wire fastening tool has the advantages of convenient use, simple operation, labor saving, high safety and simple structure.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a torque threading tool. Background technique [0002] During civil construction, steel bars need to be bound by steel wires before concrete casting. Usually, the above-mentioned steel wire binding operation is all done manually by the operator during civil construction. [0003] Apparently, its work efficiency of manual steel wire is low, and wastes time and energy in the steel wire process. [0004] In addition to civil construction, steel wires often need to be bundled in daily life. The operator usually uses a vise to clamp the steel wires and then twists the steel wires. However, in the actual operation process, the steel wire is easy to break away, and it is inconvenient to use. At the same time, the operator's hand is close to the steel wire, which can easily cause injury to the operator's hand during the binding process. Contents of the invention [0005] The object o...
