[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment of a magnetic fixed fastener, comprising a sub-fixing member 1, a female fixing member 2, a locking fastener 3, a locking ring 4 and an electromagnet 5. The sub-fixing member 1 is fixedly connected to the female fixing member 2 through the locking fastener 3, and the sub-fixing member 1 is located at the upper end of the female fixing member 2, the locking ring 4 is fixedly connected to the bottom end of the female fixing member 2, and the electromagnet 5 is evenly fixedly installed on the outer end of the locking ring 4. The locking fastener 3 can be conveniently provided to fix the sub-fixing member 1 on the female fixing member 2, and the locking fastener 3 can be conveniently and quickly removed from the sub-fixing member 1 and the female fixing member 2 to realize unlocking, so that the sub-fixing member 1 can be conveniently removed from the female fixing member 2, so that the sub-fixing member 1 and the female fixing member 2 can realize continuous and convenient fixed locking and disassembly separation.

[0018] The locking fastener 3 includes a sliding locking magnet block 6, a locking column 7 and a limiting pressing plate 8. The limiting pressing plate 8 is evenly connected to the upper end of the locking column 7. There are three sliding locking magnet blocks 6. The three sliding locking magnet blocks 6 are evenly slidably clamped inside the bottom end of the locking column 7.

[0019] A lifting handle 9 is fixedly connected to the middle of the upper end of the locking column 7 for easy lifting.
