[0027] A transmitter body 306 is arranged inside the protective box 2, a display screen 307 is fixedly installed on the left side of the transmitter body 306, a sensing rod 308 is fixedly installed on the outer surface of the transmitter body 306, two connecting columns 9 are fixedly connected to the outer surface of the transmitter body 306, and the two connecting columns 9 are fixedly connected to the side faces away from each other with sleeves 10.
