Wire threaded sleeve: A spiral made of diamond-shaped wire. The outer surface forms an external thread and the inner surface forms an internal thread. Mounting handle: A straight shank that is bent inward at one end of the wire threaded sleeve. Specially used to screw the wire screw into the screw hole. When installing the wire screw sleeve, use a special tool to pass through the wire screw sleeve, clamp the mounting handle, and screw the diameter of the wire screw sleeve to screw the wire screw sleeve into the screw hole. Guidance: At the end of the wire screw sleeve mounting handle, the diameter of the wire screw sleeve within 210 degrees of the mounting handle is reduced, so that the end of the wire screw sleeve can smoothly enter the screw hole when the screw thread is screwed into the screw hole. This section of the wire screw sleeve is called the guide. Folding end groove: A notch designed to remove the mounting handle. After the wire screw is screwed into the screw hole, the mounting handle loses its effect, which in turn affects the screw passing through the wire screw sleeve. In some cases, the mounting handle needs to be removed so that the screw is not obstructed by the threaded screw. To this end, a notch is formed in the guide section at 30 to 90 degrees from the mounting handle so that the mounting handle can be broken therefrom when the mounting handle is impacted by a tool.
