The power monitor is used by connecting to the circuit and displaying the voltage, current, and power in the circuit through intuitive digital displays. Before testing, the external line needs to be manually connected to the monitoring device. There is a risk of electric shock when connecting, so it is necessary to develop an anti-electric shock power monitoring device.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when the external cable is connected to the device, the bolt drives the lower pressure plate to squeeze the internal connecting wire and the external connecting wire into contact. Under the action of pressure, the internal connecting wire will be displaced and the lower pressure plate will rub against the internal connecting wire. After long-term use, the connection between the internal connecting wire and the connecting tube will become loose or even fall off, and the lower pressure plate will wear the internal connecting wire. After long-term use, it is easy to cause safety hazards and the falling off of the internal connecting wire will affect the test results, reducing the accuracy of the monitoring data.
