[0017] In operation, the screw is sucked by the suction nozzle 2 and then lowered, and when the screw is inserted into the corresponding hole of the product, the screw locking assembly 1 (preferably an electric screwdriver) is actuated to screw the screw in the suction nozzle 2, thereby achieving the effect of high-precision positioning and screw locking.

[0018] In the embodiment, the inductor 31 is a displacement sensor, and the inductor 31 has a movable contact end, and the trigger 32 is used to abut against the contact end and force the contact end to displace relative to the inductor 31. That is, after the trigger 32 abuts against the contact end of the inductor 31, the contact end is forced to move, and the displacement sensor can quickly respond and send a corresponding signal, thereby controlling the external lifting mechanism to stop further lowering, so as to ensure that the utility model will not be lowered too much.
