[0002] Electric tapping machine is a machine tool that can tap internal threads of various small and large steel parts with coarse pitch, fine pitch, non-standard pitch, forward and reverse fastening connection threads, transmission connection threads and pipe threads. This type of machine tool belongs to the category of flexible tapping. Its notable feature is that it can be operated with folding arms and is suitable for tapping threads below M42. During the process of processing the workpiece, the workpiece is moved to the corresponding processing position through the corresponding guide mechanism.

[0003] The related art (publication number: CN217044912U) discloses a workpiece adjustment guide rail device for an electric tapping machine, and the disclosed technical solution is as follows: arc grooves are arranged on both sides of the slide rail body, and the arc grooves can limit the position of the sliding seat, so that the sliding seat can only move along the direction of the slide rail body; under the action of the clamping spring, the sliding block drives the clamping column to extend out of the fixed cylinder, and then the clamping column extends out of the fixed cylinder and fits with a side wall of the processing part placed inside the clamping frame. Through this design, the acting force between the processing part and the clamping frame is increased to prevent the processing part from moving relative to each other during the tapping process; the fixed frame is adsorbed on the inside of the rectangular groove by the adsorption magnet, and then the lubricating cotton fits with the two walls of the slide rail body, and this effect can achieve the purpose of lubrication, and prevent the slide rail body from being seriously worn due to long-term use;

[0004] In the above disclosed technical solutions, it is found that the following problems exist in the related technology: in the process of clamping and fixing the workpiece, the workpiece is fixed by the elastic force of the spring. After long-term use, the elastic coefficient of the spring will change, resulting in displacement of the workpiece during processing, thereby affecting the processing quality. In this regard, we propose a new workpiece adjustment guide rail mechanism for an electric tapping machine;
