[0018] like Figure 1 As shown, a guide box 4 is fixedly installed on the top of the base plate 1, and a collecting box 6 is slidably installed inside the guide box 4. A plurality of collecting slots 5 are provided on the top of the guide box 4, and a handle 9 is provided on the front side of the collecting box 6, so that the device can collect metal debris generated by the device during thread processing, prevent the metal debris from polluting the working environment of the device, and improve the practicality of the device.

[0019] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, an electric slide rail 10 is fixedly installed on the top of the mounting frame 3, an electric slider 11 is slidably installed on the electric slide rail 10, a connecting rod 12 is fixedly installed on the bottom of the electric slider 11, and a transmission box 13 is fixedly installed on one end of the connecting rod 12. Two sets of transmission rods 19 are rotatably installed inside the transmission box 13 and are distributed front to back. A transmission wheel 20 is fixedly installed on the transmission rod 19, and a transmission belt 21 is sleeved on the transmission wheel 20, and the transmission wheel 20 is arranged to be driven by the transmission belt 21. A second threaded rod 14 is rotatably installed on the bottom of the transmission box 13 and is distributed front to back. One end of the second threaded rod 14 extends into the interior of the transmission box 13 and is fixedly connected to the transmission rod 19. The other end of the second threaded rod 14 is rotatably connected to the placement frame 15, and a knob 16 is rotatably installed on the bottom of the placement frame 15. One end of the knob 16 passes through the placement rack 15 and is fixedly connected to the second threaded rod 14. A second threaded connecting block 18 is threadedly installed on the second threaded rod 14. A buffer rack 22 is fixedly installed between the second threaded connecting blocks 18. A sliding groove is provided on the front and rear inner walls of the buffer rack 22. A slider is slidably installed inside the sliding groove. A sliding plate 23 is fixedly installed between the sliders. Three groups of buffer springs 24 are fixedly installed on the bottom of the buffer rack 22 and are distributed front and back. One end of the buffer spring 24 is fixedly connected to the sliding plate 23. A fixed plate 25 is fixedly installed on the bottom of the sliding plate 23, so that the device can adjust the support position of the fastener body 17, and at the same time can better clamp and fix the fastener body 17 to prevent it from moving during the processing process, thereby improving the stability and processing accuracy of the device.

[0020] Working principle: When in use, by controlling the electric slide rail 10 and the electric slider 11 to start, it can adjust the position of the two sets of placement racks 15 to a certain extent, and place the fastener body 17 on the placement rack 15, and by turning the knob 16, the knob 16 can simultaneously drive the two sets of second threaded rods 14 to rotate through the transmission setting of the transmission wheel 20 and the transmission belt 21. The rotation of the second threaded rod 14 can drive the buffer rack 22 to move longitudinally through the setting of the second threaded connecting block 18, and then can drive the fixed plate 25 to press down so that the fixed plate 25 contacts the fastener body 17. At this time, continue to rotate the knob 16. Due to the sliding setting of the sliding plate 23 and the buffer spring 24, the sliding plate 23 will squeeze the buffer spring 24, so that the spring force of the buffer spring 24 increases, thereby making the fixed plate 25 able to fix the fastener body 17 more stably. By controlling the first motor 802 to start, the second A motor 802 can drive the first threaded rod 803 to rotate. At this time, the first threaded connecting block 804 threadedly installed on the first threaded rod 803 will move laterally through the rotation of the first threaded rod 803, so that it can drive the mounting plate 807 and the thread processing drill bit 808 to move laterally through the setting of the connecting ring 805. At the same time, when the first threaded rod 803 rotates, it can drive the telescopic connecting rod 806 fixedly installed inside the first threaded rod 803 to rotate, so that the telescopic connecting rod 806 can drive the thread processing drill bit 808 to rotate, and then the thread processing drill bit 808 can thread the inside of the fastener body 17. The debris generated during the thread processing will fall to the top of the guide box 4 due to the influence of gravity and enter the collection box 6 through the setting of the collection groove 5 for collection. By pulling the handle 9, the debris collected in the collection box 6 can be cleaned uniformly.
