Manual bundling tool

Abstract

The purpose of the present invention is to provide a manual bundling tool that is improved in such a manner that, by further refining a mechanism for applying plastic deformation to a tie positioned on a head so as to forcibly engage ties, the tie can be plastically deformed while being firmly supported, without the disadvantage of an extrusion force acting on the head dissipating, thereby enabling more reliable retention to be performed. Thus, the manual bundling tool is provided with: a tie holding part (g) that receives the head (5) so as to support the head; a tightening mechanism (a) that pulls a protruding tie section (4a) that protrudes through the head (5), which is supported by the tie holding part (g), toward the head (5); an anti-return mechanism (j) that stops a return movement of the protruding tie section (4a) wit respect to the head (5), which is supported by the tie holding part (g); and an extrusion mechanism (h) that forces a pass-through tie section (4c), which is positioned at the head (5), to be extruded while the head (5) is being supported by the tie holding part (g), so that a deformed section (4b) is engagingly inserted in an engagement hold (10) of a base tie section (4d) where the head (5) is held outside a range in advance.

Description

technical field [0001] The present invention relates to a manual binding tool for binding a tie (binding band), and particularly relates to a manual binding tool suitable for a binding operation using a metal binding tie. Background technique [0002] As a binding tie (binding band), as disclosed in Patent Document 1, a binding tie made of synthetic resin is known in which the head is equipped with a detachment preventing function of the tie portion by means of ratchets or the like. Binding ties made of synthetic resin are inexpensive and easy to handle, and are often used as relatively light-load binding members such as wire harnesses. [0003] This tying tie can be tied to the object to be tied just by pulling the tie part with your fingers, and when a strong tension is required, it can also be reliably and firmly fastened by using a tying tool. bundled. [0004] In addition, for bundling where greater strength is required, such as bundling a plurality of metal pipes, a ...

Problems solved by technology

[0006] However, in the structure that utilizes the self-locking effect produced by the ball to prevent disengagement and maintain the tension force, for example, when strong vibrations and impacts act on the object to be bound and the binding tie itself, there will be instantaneous movement of the ball, and the tie will Possibility of slightly withdrawn movement at the end, there is a danger of becoming functionally unstable

In addition, even when the concave deformation by the ball occurs, the concave engagement portion itself is deformed by the self-locking action of the ball, so there is a point of whether it is strongly pressed to the extent that a reliable engagement can be realized. room for improvement
