In this embodiment, the number of the pressing blocks 3 is the same as the number of the magnet steels 11 of the rotor 10 and the number of the avoiding grooves 6, so that the magnet steels 11 in all the magnet steel grooves of the rotor 10 can be pushed and pressed at one time, and the efficiency of demagnetizing the steel is high.

Example two
The embodiment is further optimized based on the first embodiment, as shown in fig. 3, the number of the pressing blocks 3 is one half of the number of the magnetic steels 11 attached to the rotor 10; the pressing blocks 3 are distributed in a circumferential array by taking the center of the pushing plate as the center, and the position avoidance grooves 6 are matched with the pressing blocks 3 in position.
The magnetic steel 11 of the motor rotor 10 is distributed in an alternating arrangement of N poles and S poles. In order to reduce the manufacturing difficulty of the tool, the punching quantity of the avoidance grooves 6 of the base 5 and the assembling quantity of the pressing blocks 3 of the pushing component are reduced, the efficiency of demagnetizing operation is considered, the pressure required by all the magnetic steels 11 in the rotor 10 to exit is high, and the number of exiting magnetic steels 11 is too small and multiple demagnetizing operations are required. Therefore, in this embodiment, the number of the pressing blocks 3 and the number of the avoiding grooves 6 are half of the number of the magnetic steels 11 of the rotor 10, so that the magnetic steels 11 with the same magnetic poles can be conveniently withdrawn at one time, and the rotor 10 can be conveniently assembled again for use.
The procedure for the use of the first and second embodiments is as follows:

In addition, the pressed magnetic steel is communicated with the avoidance groove of the base when in press mounting; if the other half of magnetic steel is needed to be pressed, the rotor is only needed to be turned upside down, the key structure is aligned to the other key groove on the base, the double key groove design can be used for one base, one base is omitted, and the cost is saved.
The tool in the first embodiment and the second embodiment can also be used for assembling the magnetic steel 11 on the rotor 10, and the implementation method is that the magnetic steel 11 is arranged in the avoidance groove 6 of the base 5, and then the magnetic steel 11 in the avoidance groove 6 is pushed into the magnetic steel groove of the rotor 10 by the pushing component, so that the rotor 10 is convenient to install the magnetic steel 11 with high efficiency.
The embodiments of the present utility model are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
