According to technical requirements, there is a certain deflection angle between the magnetic steel and the rotor core, such as 8 degrees, 12 degrees, etc.

[0003] However, the deflection angle of some existing magnetic steel tools is fixed, so the magnetic steel tools cannot be rotated to flexibly change the deflection angle, resulting in limitations in the use of some magnetic steel tools and reduced work efficiency. Utility Model Content

The upper surface of the positioning middle plate passes through the interior of the bottom plate and is provided with four groups of equidistant through-grooves. The interior of the through-grooves is rotatably connected to a corner plate, and the area between two adjacent corner plates is a tooling area of ​​magnetic steel. Both ends of the corner plates are rotatably connected to a rotating shaft.

[0007] Optionally, an anti-slip sleeve is fixedly sleeved on the outer portion of the upper end of the iron core shaft.

[0008] Optionally, a dial is fixedly sleeved on the outer surface of the rotating plate, and a rotation scale is marked on the dial.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

The rotating plate will also drive the rotating shaft and the corner plate connected to the rotating seat to tilt and rotate at a corresponding angle in the rotating slot to match the deflection angle of the magnetic steel tooling, thereby ensuring the flexibility and practicality of the rotating angle of the magnetic steel tooling.
