[0002] An electric motor, commonly known as a motor, refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors and generators. According to the type of working power supply, it can be divided into DC motors and AC motors.

[0003] The motor rotor refers to the rotating part of the motor, which is divided into the motor rotor and the generator rotor. When installing the motor rotor in the motor, it needs to be driven by a sling for installation.

[0004] When installing the motor rotor, it is necessary to place the lifting tube of the lifting device on the surface of the rotating shaft of the electronic rotor, and then drive the motor rotor to move through the lifting tube. However, the existing lifting tube cannot fix the rotating shaft of the motor rotor, so that the rotating shaft of the electronic rotor is easy to fall off from the inside of the lifting tube during installation, which can easily cause damage to the electronic rotor.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
