When power is supplied to the power coil 23, when current passes through the power coil 23, the generated magnetic field will magnetize the iron core 18, thereby providing suction to the square screw.

[0026] like Figure 1-5 As shown, an adjusting ring disk 12 is rotatably connected inside the adjusting housing 7, and the adjusting ring disk 12 is located at the rear end of the fixed ring block 8. A sliding pin 10 is fixed to one end of the sliding blocks 9 away from each other. An arc-shaped sliding groove 13 is provided at the adjusting ring disk 12 corresponding to the sliding pin 10. The rear end of the sliding pin 10 is rotatably connected to the inside of its corresponding arc-shaped sliding groove 13. When the adjusting ring disk 12 rotates, multiple sliding blocks 9 can be driven to move closer to or away from each other, so that multiple sliding blocks 9 can complete the positioning and limiting function of the square screws.

The worm 15 rotates and cooperates with the worm gear 14 to drive the adjusting ring disk 12 to rotate. When the adjusting ring disk 12 rotates, the sliding pin 10 is squeezed and driven through the arc-shaped slide groove 13. However, the sliding pin 10 receives the limiting effect of the fixed ring block 8 through the sliding block 9, so that when the adjusting ring disk 12 rotates, the multiple sliding blocks 9 are driven to move closer or farther from each other, so that the multiple sliding blocks 9 complete the positioning and limiting of the square screw. The power supply coil 23 is powered by the battery 19. When the current passes through the power supply coil 23, the magnetic field generated will magnetize the iron core 18, thereby providing suction to the square screw. The driving gear 22 is driven by the driving motor 5 to cooperate with the power supply coil 23 to drive the outer ring shell 4 of the magnet to rotate, thereby realizing the function of rotating and installing the square screw. The function of limiting and fixing the square screw can be realized through multiple extrusion blocks 11, thereby improving the stability and accuracy during installation, providing sufficient gripping force and positioning force for the square head of the square screw, facilitating installation operation, and improving the flexibility of the device.
