Description

Screwdriver wire bundling device

Technical Field

The utility model relates to a mechanical tool field, concretely relates to screwdriver wire bundling device.

Background

Due to their good toughness, elastoplasticity and tensile strength, wire has been the second choice for high strength strapping, with the most typical wire used for strapping being iron wire. The wire used for bundling is usually used for bundling reinforcement bars in construction sites, and is only used for roughly fixing the reinforcement bars and is not usually required to bear large stress and bundling force. For the binding of thicker wires, such as wires with a diameter greater than 1.5mm, which are subjected to high loads and have high binding stress, the binding hooks are no longer suitable, and binding are usually performed by using pliers or wire cutters.

The principle of binding and binding whether the binding hook is a binding hook or a vice or a wire cutter is that the free ends of two or more iron wires are twisted to be twisted in a twist shape, the part of the iron wires which are not wound becomes shorter gradually along with the winding, and the process of shortening the part of the iron wires which are not wound is the binding process. Although the binding method is very common, the binding effect is not good, and the binding method is mainly characterized in the following two aspects:

(1) Cannot be strapped tightly enough and can provide limited strapping stress. The principle of the binding method is that the free end of the iron wire is twisted in a twist shape to shorten the part which is not twisted, but the stress required by deformation is increased along with the winding, the difficulty of continuously twisting the iron wire in the twist shape is increased by using a tool which works by friction force, such as a vice, and even if the free end of the iron wire can be continuously twisted in the twist shape, the result is that the part which is not twisted in the iron wire can not be continuously shortened. This is why the strapping method cannot provide sufficient tightness and provides limited strapping stress. For application scenes which need to be bound very tightly and have very large binding stress, the binding and binding method is not applicable;

(2) After the twisted wire is wound and tied, a twisted end part is left, so that the twisted wire is not beautiful and is difficult to get in the way, the twisted wire is easy to prick hands or bodies of users and hang clothes of the users, even if the twisted wire is cut short, the twisted wire cannot be completely avoided, and if the twisted wire is cut short, the tied wire is easy to scatter and lose efficacy due to insufficient stress at the end part connecting part.

In view of the above problems, the inventor believes that it is necessary to provide an effective tool for high-strength binding of metal wires such as iron wires, which not only can provide a sufficiently large binding prestress, but also can make the binding effect simple and beautiful without obvious hand pricking or residual protrusions at free ends of the iron wires which are easy to hang on clothes.
