Description of the invention (I) < Background of the invention > < Field of invention > The present invention relates to a tang cutting tool, The tang cutting tool can break a tang to remove the tang after inserting a helical coil insert into a threaded hole of a workpiece using a tang. < Explanation of the related technology > When tapping a tapped hole directly on a light metal-for example, aluminum, plastic, wood, or cast iron-a fragile female thread makes it impossible When obtaining a high locking force, the traditional practice is to use a helical coil insert with a tang to ensure a high and reliable thread locking force. Figure 5 illustrates an example of such a helical coil insert with a tang. As shown in Fig. 5, a spiral wire insert with a tang 10 is often made by winding a special steel wire of high strength to form a spring-shaped cylinder. This special steel wire has a rhombus-shaped cross section. This spiral coil insert can be screwed into a threaded hole 101 of the workpiece 100 by an insertion tool and fixed there, as shown in FIG. 6. After that, a bolt 20 or the like is screwed in to form a threaded engagement with the helical coil insert 10 which is a female thread. By using the above-mentioned spiral coil insert 1 〇, a high strength screw hole locking force can be obtained to repeatedly insert and remove the bolt 2 〇 because the above-mentioned insertion tool will be provided with a handle Spiral coil installation of the foot ------ IT ------ place Γ Please read the precautions on the back before filling out this page) The M's scale is applicable to the Chinese national standard (⑽) (21〇χ297 (Public Director) 4 ^ 9413 Α7 Β7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (less) Piece 10 is screwed into the threaded hole 1 0 1 and a stopper 1 1 is along the The radial direction of the coil is folded into a well-known tang, which can be connected with the insertion tool. Such a tang is set at the free end of the bobbin, as shown in FIG. After the spiral coil insert 10 is fixed in the threaded hole 1 ο 1 of the workpiece 1 ο 〇, the tang must be removed. In order to achieve this, a notch 12 is formed on the outer surface of the coil at the first loop portion connected to the free end of the coil provided with the tangs 1 1. From the helical coil insert 10 with a tang as described above, after it is attached to the workpiece 100, the tang 11 is broken, and the broken tang 11 must be collected. Especially, when the threaded hole 101 of the workpiece 100 is a blind hole, such operation is very difficult. If the broken tang 11 is not collected, the tang 11 may cause electrical or mechanical failure. It must therefore remove the separated tangs without any omissions. When the threaded hole 101 of the workpiece 100 is set as a blind hole, the current practice is to remove the broken tang 11 by using, for example, the method of dumping the workpiece 100. However, when the size of the workpiece is large, this practice is not effective. When the size of the helical coil insert 10 with a tang is large, the broken tang can be removed by using tweezers or the like. However, for small-diameter spiral coil inserts 10 with tangs, this approach is sometimes not applicable. Therefore, an easy and reliable method is needed to remove the broken tangs. 0 4 ^-(Please read the precautions on the back of the page before filling in this page) The size of the paper used for the guide is Xin Guoguo. ) A4 specification (210X297 mm) 419415 A7 _______—_ B7______ V.
