[0026] At the same time, the rotating table 7 is installed in the middle of the upper end of the workbench 1, and an electric slide rail 14 is arranged near the edge of the upper end of the rotating table 7, the outer end of the electric slide rail 14 is connected with a matching electric slider 15, and the outer side of the upper end of the electric slider 15 is fixedly installed with a clamping block 16 by bolts, the middle of the lower end of the rotating table 7 is fixedly installed with a mounting column 8 located in the workbench 1, and the middle outer side of the mounting column 8 is integrally fixedly installed with a mounting plate 9, and the interior of the mounting plate 9 is evenly provided with positioning holes 10 matching the positioning rod 11 at equal angles, a handle 18 is fixedly installed on the periphery of the rotating table 7, and a placing table 17 located on the upper surface of the rotating table 7 is arranged on the inner side of the electric slide rail 14, and the combination constitutes a tapping machine for the production of high-precision fasteners.

[0027] When using the high-precision fastener production tapping machine, the specific Figure 1 and Figure 3 As shown, first, the whole is stably placed on a designated plane through a tripod, and then the fasteners to be tapped are placed on the placement table 17 just in front of the upper surface of the rotating table 7, and the electric slide rails 14 at the corresponding positions are started through the control panel, so that the electric sliders 15 on the same horizontal line can move relative to each other on the electric slide rails 14, thereby facilitating the relative movement of the two groups of clamping blocks 16, and then facilitating the fasteners to be firmly clamped by the clamping blocks 16;
