[0050] The limiting columns 24 are equidistantly passed through the outer edge of the mounting plate 21, and the inner rear end of the outer shell 11 is equidistantly provided with limiting holes, and the rear end of the limiting columns 24 is sleeved in the limiting holes;

[0051] The sleeve connection between the limiting column 24 and the limiting hole is used to fix the mounting plate 21. The sleeve connection method is convenient for disassembly and assembly of the structure.

[0052] Also includes a connecting portion;

[0053] The connecting part includes a connecting block 41, a connecting hole 42, a threaded hole 43 and a screw 44;

[0056] Also includes an interface portion;

[0057] The interface portion includes an input interface 51, a first output interface 52, a second output interface 53 and a wiring port 54;

[0070] Working principle: When the vibration sensor 22 does not detect the generation of vibration force, a group of emergency protection plates 33 are at an angle to the horizontal plane. Once the vibration sensor 22 detects the generation of vibration force, the controlled rotating motor 31 can apply a rotating force to the hole block 32, linking the emergency protection plate 33 to rotate, and convert the horizontal angle of the emergency protection plate 33 to form an upper isolation protection for the power conversion module 13;

[0071] This step can provide emergency protection for the power conversion module 13, reduce the degree of damage, and save costs.
