It should be noted that, as described above, when the foolproof operation is to be performed, the first magnetic attraction member 30 and the second magnetic attraction member 40 are each magnets, and when the foolproof operation is not required, one of the first magnetic attraction member 30 and the second magnetic attraction member 40 may be made into a magnet, and the other may be made into a structure without magnetism, so that the purpose of magnetic attraction between the first magnetic attraction member 30 and the second magnetic attraction member 40 can be achieved.

In addition, since the first magnetic attraction member 30 is mounted on the insulating male seat 11 and is located in the fastening space 211, the shape, size, position, etc. of the first magnetic attraction member 30 can be flexibly designed according to the fastening space 211, for example, the height and size can be changed, the flexibility is enhanced, different shapes and areas can be designed, and the second magnetic attraction member 40 mounted on the insulating female seat 21 can be correspondingly adjusted. In addition, since the first magnetic attraction piece 30 only occupies the position of the insulating male seat 11 and the second magnetic attraction piece 40 occupies the position of the insulating female seat 21, and the first magnetic attraction piece 30 and the second magnetic attraction piece 40 are respectively used as one component, the current environment of the insulating male seat 11 and the insulating female seat 21 is not affected, and the method is applicable to diversified environments. In addition, the first and second magnetic attraction members 30 and 40 can be used for a long period of time with advantages in terms of materials and options.
