[0026] Example 1:
[0027] The energization wire 45 is wound on the energization solenoid 41 counterclockwise. When the power supply 1 is turned on, a current is generated in the energization wire 45. At this time, the upper end of the energization solenoid 41 is the N pole and the lower end is the S pole, so the energization solenoid 41 The wire tube 41 and the iron magnet 42 attract each other, and the insulating baffle 44 is kept under the switch 2; the circuit current controller 3 can be adjusted to the maximum resistance before the knot is tied, so that the attractive force between the energized solenoid 41 and the iron magnet 42 At this time, the magnet 42 can be pulled up with a little pulling force to make the light-emitting reminder 5 glow. In the process of practicing knotting, the resistance value of the circuit current controller 3 can be gradually reduced, that is, the pulling force generated during knotting should be as small as possible, thereby increasing the diff...
