[0024] Furthermore, in this embodiment, the external joint 31 is formed with a disc portion 311 for connection to the front end section 302 and an external connecting rod 312 vertically connected to the center of the top surface of the disc portion 311; the disc portion 311 is provided with a countersunk hole 313 at its front and rear ends, and the front end section 302 is provided with a connecting hole 305 corresponding to each countersunk hole 313, for bolts to pass through the corresponding countersunk holes 313 and the connecting holes 305 in sequence to fix the external joint 31.

[0025] Furthermore, in this embodiment, the outer diameter of the disc portion 311 is tangent to the central axis of the two pressing heads 32 and the front edge of the lifting seat 30, so that the lifting drive structure can drive the lifting seat 30 to descend relative to the base 10, and the pressing head 32 can press the bearing 101 into the fastening cover body 102 with a more stable force.

[0026] Furthermore, in this embodiment, the end of the positioning column 321 is in a cone shape, so that the positioning column 321 can pass through the inner ring hole of the bearing 101.

[0027] In summary, the present invention is a tool for processing the rotor fastening cover of a shaded pole motor.
