Description

Technical Field

[0001] The present invention relates to the technical field of medical tool processing equipment, in particular to a processing machine tool for oral examination tools. Background Art

[0002] With the improvement of living standards, more and more people pay attention to oral health, especially teeth. For dental examination, many tools are needed, such as mouth mirrors, sickle-shaped scalers, double-headed probes, hoe-shaped scalers, tweezers, etc.; and the production of these tools is often made through stamping and polishing processes. For example, the production of a mouth mirror includes a mouth mirror handle and a mouth lens, and the mouth lens includes a support plate for mounting the lens and a connecting handle connected to the support plate. The connecting part between the connecting handle and the support plate is flattened by stamping and welded to the support plate. The connecting part between the connecting handle and the support plate is bent, and the connecting handle is connected to the mouth mirror handle through a thread at the end.

[0003] In the related art, some connecting handles are reducing diameter connecting handles, in which one end of the connecting handle is thick and the other end is thin. The thicker end of the connecting handle is connected to the mirror handle, and the thinner end of the connecting handle is connected to the support plate. The purpose of using reducing diameter connecting handles is to increase the strength of the connecting handle and make the mirror connecting handle part not easy to bend; and the connecting handle is made by the operator placing the thinner end of the pre-produced reducing diameter metal rod in a punching machine to punch it into a flat shape, and then placing the flat end of the metal rod in a bending machine to bend it at a certain angle.
