[0027] Specific working principle:

[0028] Before using the utility model, first connect the utility model to an external power supply and a control panel, and control the operation of the utility model through the external control panel. When tapping a bolt, first place the screw head part of the bolt between the three claws of the three-jaw chuck 18 and fix it, then start the motor three 23, the motor three 23 drives the one-way screw two 20 to rotate, so that the movable block two 14 threadedly connected with the one-way screw two 20 drives the movable frame 15 to approach the three-jaw chuck 18 until the top cone 17 supports the end of the bolt, thereby completing the fixing of the bolt. After the fixing is completed, start the motor one 21, and drive the bidirectional screw 6 to rotate through the motor one 21, and the bidirectional screw 6 can be fixed.
