[0026] The knife handle 8 has a connecting plate 19 fixed to its end surface, and an external thread 18 is provided on the surface of the connecting plate 19. A pentagonal cavity 20 is provided on the end surface of the connecting plate 19, and a pentagonal column 21 is fixed in the pentagonal cavity 20. A pentagonal slot 13 is provided inside the pentagonal insert frame 12, and the pentagonal insert frame 12 can be inserted into the pentagonal cavity 20, and the pentagonal column 21 can be inserted into the pentagonal slot 13;

[0027] When in use, first insert the pentagonal column 21 into the pentagonal slot 13 accordingly, and at the same time insert the pentagonal insert frame 12 into the pentagonal cavity 20 accordingly, and then rotate the nut ring 6 to connect the internal thread 14 in the nut ring 6 and the external thread 18 of the connecting plate 19, thereby realizing the connection between the knife body 4 and the knife handle 8. At this time, the stop end 17 will press against the stop block 11. By rotating the nut ring 6 and removing the nut ring 6 from the connecting plate 19, the knife body 4 and the knife handle 8 can be separated, and the operation is relatively convenient.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, the stop end 17 can be inserted into the inner groove 9, a plurality of magnetic blocks 10 are provided, and the plurality of magnetic blocks 10 are evenly distributed in the inner groove 9, and the magnetic blocks 10 can be attracted to the stop end 17;

[0030] When in use, when the stop end 17 of the nut ring 6 is moved to the inner groove 9, the magnetic block 10 will attract the stop end 17 to achieve the unchanged position of the nut ring 6 and improve the stability of the nut ring 6;
