[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0027] Example: In use, firstly, the robotic arm 30 controls the connecting plate 29 to move the device to the front of the automated storage unit 1 to grip and store the workpiece 3. The positioning pin 41 is passed through the through hole 44 to position the workpiece 3 on the crossbeam 2 of the automated storage unit 1, and the positioning hole 20 is embedded in the positioning groove 22. The cylinder is activated to drive the positioning rod 42 to push the positioning bead 21. Since the positioning rod 42 has a ramp, when air is supplied, the positioning bead 21 is embedded in the positioning groove 22, connecting the adapter to the workpiece 3. When the air is cut off, the positioning bead 21 disengages from the positioning groove 22, and the adapter separates from the workpiece 3. Secondly, the cylinder 8 is activated, which drives the electric screwdriver mounting base 7 to move the screwdriver bit 14 close to the workpiece 3 and activates the electric screwdriver 9. The detection sensor 27 determines whether the screw 37 on the workpiece 3 is loosened. When the head of the screw 37 touches the contact switch, the electric screwdriver 9 stops rotating. At this time, the workpiece 3 can be disassembled. The front detection sensor 23 determines whether the screw on the workpiece 3 is loosened. When the screw 37 is tightened to the correct position, its head touches the contact switch, stopping the electric screwdriver 9 from rotating. At this point, the workpiece 3 is fixed in the automated storage unit 1. The electric screwdriver 9 remains stable during rotation via the universal joint and tightening universal joint 13. The rotation of the electric screwdriver 9 causes the floating guide rod 11 to move, which in turn moves the connecting shaft 32. This generates a force during tightening, holding the screw 37 in place, thus facilitating use and enabling quick installation and removal of the workpiece 3. Simultaneously, by moving the sliding sleeve 35, the retaining ring 40 can be disassembled, causing the retaining block 38 to disengage from the retaining groove 36 and the limiting bead 16 to disengage from the limiting hole. This allows for the replacement of the screwdriver bit 14, improving the device's practicality and flexibility, and making it easier to use. The limiting stop 25 limits the electric screwdriver mounting base 7. Since the limiting stop 25 is threadedly connected to the limiting bolt 26, the position of the electric screwdriver mounting base 7 can be adjusted according to usage to reduce errors and improve work efficiency.
