[0028] The guide support assembly is located on the side of the support assembly, and the guide support assembly includes a first support plate 7, a second support plate 8, and a guide rod 9.

The sliding guide rod 2 passes through the first through hole on the locking component 1. When the sliding guide rod 2 is not locked by the locking component 1, the sliding guide rod 2 can move axially along the first through hole.

[0030] The locking component 1 includes a locking cylinder 1a and a locking cylinder seat 1b. The locking cylinder 1a is fixed on the locking cylinder seat 1b. The locking cylinder seat 1b is fixed to the base plate 12. The locking component 1 also includes an air valve 1c. The air valve 1c is connected to the locking cylinder 1a.

[0035] like Figure 3 and Figure 4 , move the slide guide rod 2 to the right (the left and right directions are based on Figure 3), match rotor A with the matching groove 6a on the rotor support 6, so that the circumference of rotor A matches the V-shaped surface in the V-shaped support 4. Put stator B into the V-shaped support 4, so that the circumference of stator B matches the V-shaped surface of the V-shaped support 4. At this time, the axis of stator B and the axis of rotor A are located on the same straight line. Move the sliding guide rod 2 to the left, the sliding guide rod 2 passes through the stator B, and the end of the sliding guide rod 2 with the assembly hole is sleeved on the shaft of rotor A. Start the air valve 1c, and the compressed gas is input into the locking cylinder 1a. The locking cylinder 1a locks the sliding guide rod 2, and the sliding guide rod 2 cannot move at this time. Push the sliding frame 10 to move linearly along the guide rod 9, and the push plate 11 moves linearly with the sliding frame 10. The push plate 11 applies a driving force to the stator B, so that the stator B moves linearly in the V-shaped support 4, and finally the stator B is sleeved on the rotor A. The above-mentioned assembly mechanism makes the axes of stator B and rotor A located on the same straight line. Therefore, whether in static or dynamic conditions, the direction of stator B will not change during the linear motion, thereby avoiding scratches or collisions with rotor A, and further avoiding damage to rotor A and stator B, thereby ensuring the performance of the motor.
