By providing the elastic telescopic rods 17 and the second buffer plates 18, the protection area of ​​both sides of the controller body 1 can be increased to avoid the occurrence of blind corners of protection. Two heat dissipation windows 19 are provided on one side of the controller body 1, and a plurality of heat sinks 20 are equidistantly provided in the two heat dissipation windows 19, and the heat sinks 20 are in an inclined state. One side of the controller body 1 is provided with The controller body 1 is fixedly connected to the heat dissipation fan 21 through the mounting groove.
