[0020] The driving assembly is used to drive the two first bevel gears 3 to rotate simultaneously, and the two first bevel gears 3 pull the two screw rods 2 to rotate, so that the two screw rods 2 pull the two L-shaped plates 5 to move downward simultaneously in a screw rod transmission manner. The two L-shaped plates 5 cooperate with the reinforcement assembly to clamp and fix the DC brushless motor, making the disassembly and assembly of the DC brushless motor more convenient, and greatly improving the disassembly and assembly efficiency of the DC brushless motor. The purpose of designing the limit plate 8, the limit rod 12 and the limit groove 13 is to prevent the fixing cylinder 4 from being completely separated from the L-shaped plate 5.
[0021] Among them, the driving component includes a dual-axis motor 9, which is arranged on a base 1. A transmission rod 10 is fixed to both output shaft ends of the dual-axis motor 9. A fixed cylinder 4 is sleeved on the outside of the transmission rod 10, and the junction of the fixed cylinder 4 and the transmission rod 10 is rotatably connected through a bearing. A second bevel gear 11 is fixed to the other end of the transmission rod 10. Two first bevel gears 3 are arranged on both sides of the dual-axis motor 9. The second bevel gear 11 located on the same side of the dual-axis motor 9 is meshed with the first bevel gear 3.
[0022] The dual-axis motor 9 is used to drive the two transmission rods 10 to rotate, so that the transmission rod 10 pulls the second bevel gear 11 to rotate. With the second bevel gear 11 meshing with the first bevel gear 3, the first bevel gear 3 can be pulled to drive the screw 2 to rotate.
[0023] Among them, the reinforcement component includes a U-shaped support plate 14, which is fixedly installed between the two fixed cylinders 4.

The rear side of the U-shaped support plate 14 is threadedly connected with a bolt 16. One end of the bolt 16 located on the inner side of the U-shaped support plate 14 is rotatably connected with a U-shaped clamping plate 17 through a bearing. A third rubber pad 18 is arranged inside the U-shaped clamping plate 17. Two guide rods 19 are fixed to the rear side of the U-shaped clamping plate 17.

[0026] When in use, the brushless DC motor is placed on the U-shaped support plate 14, and the front side of the brushless DC motor is close to the U-shaped support plate 14, and the bolt 16 is tightened with a wrench, so that the bolt 16 pushes the U-shaped clamping plate 17 to move closer to the brushless DC motor. Under the cooperation of the U-shaped support plate 14 and the U-shaped clamping plate 17, the brushless DC motor can be clamped, and the second rubber pad 15 and the third rubber pad 18 can provide shock absorption protection for the operation of the brushless DC motor;
[0027] The dual-axis motor 9 is controlled to drive the two transmission rods 10 to rotate, and the transmission rod 10 pulls the second bevel gear 11 to rotate. With the help of the second bevel gear 11 engaging with the first bevel gear 3, the first bevel gear 3 can be driven to pull the screw rod 2 to rotate. The screw rod 2 drives the carrier block 7 to pull the L-shaped plate 5 downward in a screw transmission manner, so that the L-shaped plate 5 cooperates with the U-shaped support plate 14 to further clamp the DC brushless motor, thereby ensuring the firmness of the DC brushless motor clamping and the stability during use. The use of the first rubber pad 6 can also provide shock absorption protection for the operation of the DC brushless motor.
