[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Limiting grooves are provided on the outer walls of the circular mounting shaft A and the circular mounting shaft B of the present invention, which limit a row of silicon steel sheets in two directions, avoiding the rotation of a row of silicon steel sheets and also avoiding the left and right sliding of a row of silicon steel sheets; the setting of the two connecting spheres A makes the insertion connection between the circular mounting shaft A and the circular mounting shaft B more stable;

[0019] In addition, the setting of the two connecting spheres B limits the heat dissipation fan, making the insertion connection between the heat dissipation fan and the circular mounting shaft B more stable; the circular mounting shaft A and the circular mounting shaft B can be separated only when force is applied, and the heat dissipation fan and the circular mounting shaft B can also be separated only when force is applied.

[0020] 2. When the circular mounting shaft B rotates, the solid inertia block can rotate simultaneously with the circular mounting shaft B. And under the action of inertia, the solid inertia block can automatically move outward by a certain distance. When the solid inertia block drives the movable extrusion frame to move outward, the movable extrusion frame squeezes the circular movable rod A and the circular movable rod B to move, so that the outer ends of the circular movable rod A and the circular movable rod B are inserted into the two helical springs A. At this time, the two helical springs A do not have elasticity, ensuring that the two connecting spheres A will not separate from the circular mounting shaft A, and also ensuring that the connecting sphere B will not separate from the radiator fan, increasing the stability during operation. When the circular mounting shaft B stops rotating, the circular movable rod A and the circular movable rod B automatically reset under the action of the two helical springs B. When the circular mounting shaft B stops rotating, it is convenient for the staff to separate the circular mounting shaft A from the circular mounting shaft B, and it is also convenient for the staff to separate the circular mounting shaft B from the radiator fan, which is beneficial to subsequent maintenance and classified recycling.

[0021] 3. When the circular mounting shaft B rotates, the synchronous pulley drives the external load to rotate, and the initial starting speed of the synchronous pulley can be lower than the speed of the circular mounting shaft B, avoiding damage to the present invention by the external load and playing an automatic protection effect. After using for a certain period of time, the staff can adjust the installation direction of the movable connection seat to make the other half of the helical springs C bear force, improving the automatic protection effect.

[0022] 4. When the circular mounting shaft A rotates, the auxiliary heat dissipation blades rotate, playing an auxiliary heat dissipation effect, and the auxiliary heat dissipation blades can move slightly to the left under the action of inertia. When the auxiliary heat dissipation blades can move slightly to the left under the action of inertia, the arc-shaped rubber block can automatically press the synchronous pulley tightly, so that the synchronous pulley can basically rotate simultaneously with the circular mounting shaft A during operation, and can appropriately reduce the compression times of the corresponding half of the helical springs C, which is beneficial to improving the service life of the helical springs C.

[0056] Specific usage method and functions of this embodiment:

[0057] When the present invention is in use, first, the staff slidably mounts a row of silicon steel sheets 600 on the circular mounting shaft A101 and the circular mounting shaft B102. Then, the left end of the circular mounting shaft B102 is inserted into the right end of the circular mounting shaft A101. Next, the winding is wound around the row of silicon steel sheets 600. After that, the mounting unit 100 is installed in the motor housing. Then, the drive protection unit 400 is installed on the circular mounting shaft A101, and four groups of auxiliary units 500 are spot-welded to the circular mounting shaft A101 to ensure that the staff can easily remove the four groups of auxiliary units 500 subsequently. When the circular mounting shaft B102 rotates, the solid inertia block 304 can rotate simultaneously with the circular mounting shaft B102, and under the action of inertia, the solid inertia block 304 can automatically move outward a certain distance. When the solid inertia block 304 drives the movable extrusion frame 302 to move outward, the movable extrusion frame 302 squeezes the circular movable rod A201 and the circular movable rod B202 to move, so that the outer ends of the circular movable rod A201 and the circular movable rod B202 are inserted into the two helical springs A105.

When the circular mounting shaft B102 stops rotating, it is convenient for the staff to separate the circular mounting shaft A101 from the circular mounting shaft B102, and it is also convenient for the staff to separate the circular mounting shaft B102 from the radiator fan 700, which is beneficial for subsequent maintenance and classified recycling. When the circular mounting shaft B102 rotates, the synchronous pulley 402 drives the external load to rotate, and the initial starting speed of the synchronous pulley 402 can be lower than the speed of the circular mounting shaft B102 to avoid damage to the present invention by the external load, achieving an automatic protection effect. After using for a certain period of time, the staff can adjust the installation direction of the movable connection seat 401 to make the other half of the helical springs C404 stressed, improving the automatic protection effect. When the circular mounting shaft A101 rotates, the auxiliary heat dissipation blades 503 rotate, achieving an auxiliary heat dissipation effect, and the auxiliary heat dissipation blades 503 can move slightly to the left under the action of inertia. When the auxiliary heat dissipation blades 503 can move slightly to the left under the action of inertia, the arc-shaped rubber block 505 can automatically press the synchronous pulley 402, so that the synchronous pulley 402 can basically rotate simultaneously with the circular mounting shaft A101 during operation, and can appropriately reduce the compression times of the corresponding half of the helical springs C404, which is beneficial for improving the service life of the helical springs C404.
