5. starting a push rod motor to enable the screwdriver bit to be sleeved outside the screw 910; starting the tightening motor A620, so that the tightening motor A620 drives the tightening output shaft A621 to rotate circumferentially, so that the first bevel gear is driven to rotate circumferentially through the second bevel gear and the third bevel gear A423, and the first bevel gear drives the tightening shaft and the bit to rotate circumferentially, so that the screw is tightened;

6. after the screws are screwed, because the screwing motor A620 continues to operate, the first helical gear cannot rotate at the moment, and the third helical gear is driven by the second helical gear to be in meshing transmission with the first helical gear, so that the third helical gear can drive the detection disc A540 and the inner cylinder A530 to overcome the elastic force of the detection pressure spring A650 to rotate. The permanent magnet is enabled to gradually rotate towards the reed switch until the reed switch is triggered, the reed switch is judged to be screwed in place at the moment, and then all parts move reversely to reset;

7. and adjusting the position of the screwdriver head according to the coordinate of the downward moving screw on the end surface of the wire groove, entering the next cycle to tighten the downward moving screw, and repeating the steps. In the in-service use, can increase the camera to can carry out remote control operation externally through the manual work, perhaps increase the industry camera in order to gather the wire casing image, thereby screw and coordinate in the discernment image, it can to pass through screwdriver mechanism one by one according to the coordinate of discernment at last. Whether this embodiment is screwed up through the mode judgement of transshipping, and compare and directly adopt the torsion meter, this kind of mode is with low costs, and is more real durable than skin.
