In addition, when the motor rotor is placed, one end of the rotor shaft, which is far away from the rotor shaft holder 2, passes through the protective support tube 82, and the protective support tube 82 is aligned with the circlip knife 6 in the axial direction of the rotor shaft. When the motor rotor is placed, the smaller end opening of the protection support tube 82 is arranged at the position where the rotor shaft is embedded with the clamp spring, and the end face of the smaller end opening of the protection support tube 82 is fixed with the gradual change ring 822. Gradual change circle 822 is the circle form, and its frame cross-section is right triangle, and gradual change circle 822 outside arc surface is connected with the arc outer wall of protection trusteeship 82 and the face of cylinder of rotor shaft respectively, and in addition, the outside arc surface tapering of gradual change circle 822 is greater than the outer wall tapering of protection trusteeship 82. Gradual change circle 822 outer wall is close to jump ring sword 6 one side and has been seted up gradual change breach 823, and gradual change breach 823 aligns with the deformation breach 821 of protection trusteeship 82.

As shown in fig. 5, the adjusting portion 83 includes a first adjusting block 831, a second adjusting block 832, an adjusting screw 833 and an adjusting cap 834, the first adjusting block 831 and the second adjusting block 832 are both rectangular block structures, bottom surfaces of the first adjusting block 831 and the second adjusting block 832 are both fixed to the upper surface of the fixing base 3, and the first adjusting block 831 and the second adjusting block 832 are respectively disposed on two sides of the protection frame 81.
