Similarly, multiple bolts need to be tightened at once during installation, which is very troublesome. Furthermore, when the power module is fixed, there is often direct contact between the bolts and the module. Since the power module is a very precise device, the module is easily damaged during the tightening process of the bolts. Utility Model Content

[0009] Preferably, the module protection mechanism comprises a power module, and four holes are formed on the top of the power module.

[0010] Preferably, the inner surface walls of the four holes are movably inserted with fixing bolts B, and the bottoms of the four fixing bolts B are fixedly connected with rubber gaskets.

[0011] Preferably, the bottom of the power module is in contact with a rubber protective pad.

[0012] Preferably, the inner walls of the four screw holes B are threadedly connected to the outer walls of the four fixing bolts B, and the top of the base is fixedly connected to the bottom of the rubber protective pad.
