A heat dissipation slot 6 is arranged at the lower end of one side of the equipment shell 4, which can disperse the heat accumulated inside the three-phase multifunctional power meter. A slideway 7 is arranged at the upper end of the heat dissipation slot 6, a slide block 8 is arranged on one side of the slideway 7, a fixed ring 9 is arranged on one side of the slide block 8, and a carrying rope 10 is arranged inside the fixed ring 9, which can facilitate the carrying of the three-phase multifunctional power meter. A fixed block 11 is arranged on the carrying rope 10, and a tape clamping piece 12 is arranged at the lower end of the carrying rope 10. A connection port 13 is arranged at the rear end of the equipment shell 4, a condensing strip 14 is arranged on one side of the connection port 13, a thermometer 15 is arranged at the upper end of the equipment shell 4, and a JS103 sound and light alarm 16 is arranged on one side of the thermometer 15, which can play a role in warning the user.

[0020] Furthermore, the thermometer 15 is electrically connected to the JS103 sound and light alarm 16, the thermometer 15 is fixedly connected to the equipment shell 4, and the JS103 sound and light alarm 16 is fixedly connected to the equipment shell 4. The temperature inside the three-phase multifunctional power meter can be monitored by the cooperation of the thermometer 15 and the JS103 sound and light alarm 16.

[0021] Furthermore, a suction cup is arranged at the lower end of the support rod 5, the support rod 5 is fixedly connected to the suction cup, there are four support rods 5, and the equipment shell 4 is fixedly connected to the support rod 5. The entire three-phase multifunctional power meter can be supported by the support rod 5.

[0022] Furthermore, the carrying rope 10 is fixedly connected to the tape clamping piece 12, and the inner diameter of the inner ring of the fixed ring 9 is slightly larger than the diameter of the carrying rope 10. The carrying rope 10 can be limited by the tape clamping piece 12.

[0023] Furthermore, a convex block is provided on the other side of the slider 8, and the convex block matches the size of the slideway 7.
