However, when the required motor model is different, the installation position corresponding to the motor's mounting hole is also different. Therefore, different mounting brackets need to be replaced to adapt to the installation requirements of different motors. This is not only time-consuming and labor-intensive, but also greatly increases the processing cost.

[0003] Therefore, there is an urgent need for a motor mounting fixture that can adapt to the installation of various types of motors and has better shock absorption effect. Summary of the invention
