[0035] Working principle: During the process of installing the screws, first select the screwdriver body 13 according to the model of the screw. The selected screwdriver body 13 follows the connecting tube 14 and moves horizontally along the slide groove of the annular frame 11. The plug-in block 12 fixedly connected to the screwdriver body 13 moves to the center position of the fixed block 9. At this time, pull the rod body 16 to center the plug-in block 12, release the rod body 16, and allow the rod body 16 to pass through the plug-in block 12 under the reverse thrust generated by the fixed block 9 elastically connected to the baffle A17 by the spring A15, and fix the plug-in block 12. The remaining screwdriver body 13 follows the connecting tube 14 to move to the fixed position. At this time, pull out the fixed column 19 that is slidably connected to the outer wall of the connecting tube 14, move the fixed column 19 to the front of the circular groove, and release the fixed column 19. At this time, the fixed column 19 returns to its original position under the reverse thrust generated by the L plate 18 elastically connected to the baffle B21 by the spring B20, and engages with the circular groove to fix the remaining screwdriver body 13.

[0036] After selecting the screwdriver body 13, the worker turns on the motor 8 and presses the frame 1 downward. At this time, the telescopic mechanism at the bottom of the frame 1 is compressed, and the telescopic rod A6 slides downward along the telescopic rod B10. The bottom plate 7 fixedly connected to the telescopic rod B10 ensures the stability of the entire device. The conversion mechanism fixedly connected to the telescopic rod A6 also moves downward at the same time, and the fixed block 9 fixedly connected to the output shaft of the motor 8 starts to rotate, thereby driving the screwdriver body 13 to rotate, pressing and rotating the screw to fix it. At the same time, the connecting rod 3 hinged to the telescopic rod A6 moves downward, and the support block 4 is rotated along the short rod 5 until it is stretched out, so that the support block 4 increases the contact area with the ground during the operation of the device, thereby increasing the stability of the device.

[0037] Until the screws are tightened and fixed, the worker loosens the frame 1. At this time, the reverse thrust generated by the telescopic rod A6 in the telescopic mechanism and the telescopic rod B10 elastically connected by the spring C22 causes the frame 1 to return to its original position, and the connecting rod 3 hinged to the outer wall of the telescopic rod A6 also moves upward, rotating the support block 4 along the short rod 5 until it is retracted.
