Automatic tapping machines have a complex structure and are expensive, which makes them unsuitable for small and micro enterprises to purchase. Manual tapping machines achieve drilling and tapping of workpieces by manually pushing the tapping machine motor body. This requires high technical skills from the operators, and the operators need to expend great physical strength. At the same time, the workpiece to be processed by the existing manual tapping machines is fixed in the vertical direction, and the workpiece is processed in the longitudinal direction. The workpiece is fixed in the longitudinal direction, and its fixing mechanism is complex and prone to displacement, which in turn affects the processing quality of the workpiece.

[0003] Therefore, there is an urgent need for a new type of tapping machine with a simple structure. Compared with a fully manual tapping machine, it has low technical requirements for operators and saves physical energy. At the same time, it has a simple fixing structure for the workpiece and strong fixing ability to ensure the processing quality of the workpiece. Utility Model Content
