[0032] As a further implementation of the present scheme, the through groove 36 penetrates the front end of the insulating extension rod 34, the embedded groove 35 is in communication with the through groove 36, the left and right sides of the sliding plate 52 are fixedly connected with limit sliding blocks, and the sliding plate 52 is slidingly connected in the embedded groove 35 of the insulating extension rod 34 through the limit sliding blocks, through the above arrangement, the clamping assembly 5 and the electric through assembly 4 are moved in the direction of the circuit, and through the cooperation of the auxiliary assembly 6, the two electric metal sheets 44 and the circuit are kept in stable circuit communication;

[0035] Workflow: When monitoring the power quality parameters of the circuit, the operator holds the insulating handle 31, and the external soft wire 2 does not affect the normal movement of the operating rod assembly 3. The setting of the insulating extension rod 34 can extend the distance between the operator's hand and the circuit. The rubber stopper 33 plays a protective role for the operator, which can improve the safety of the operator during operation. The through groove 36 opened in the operating rod assembly 3 is placed outside the circuit. When the circuit is located between the auxiliary assembly 6 and the clamping assembly 5, the electric telescopic rod 51 is started by controlling the button 32. The electric telescopic rod 51 drives the components on one side of the electric telescopic rod 51 to move as a whole. At this time, the sliding plate 52 is slidingly connected to the inside of the built-in groove 35, which can improve the stability of the sliding plate 52 during movement. When the electric contact metal sheet 44 contacts the circuit, the electric contact metal sheet 44 and the arc-shaped rubber sheet 56 on the auxiliary assembly 6 move at the same time. The structure of the auxiliary assembly 6 is the same as that of the clamping assembly 5 except for the electric telescopic rod 51 and the sliding plate 52. The sliding plate 52 of the auxiliary assembly 6 is fixedly connected with the built-in groove 35 opened in the insulating extension rod 34. The cross column 55 of the auxiliary assembly 6 extrudes the spring telescopic rod 54, and the arc-shaped rubber sheet 56 of the clamping assembly 5 extrudes the spring telescopic rod 54. The spring telescopic rod 54 plays a buffering role when the arc-shaped rubber sheet 56 moves. At the same time, the elasticity of the spring telescopic rod 54 can improve the stability of the contact between the electric contact metal sheet 44 and the circuit. When the electric contact metal sheet 44 and the arc-shaped rubber sheet 56 contact the circuit, they will deform to a certain extent. The setting of the electric contact metal sheet 44 and the arc-shaped rubber sheet 56 can improve the clamping range when monitoring circuits of different diameters. At the same time, when the electric contact metal sheet 44 and the arc-shaped rubber sheet 56 deform, the spiral soft wire 43 moves and shrinks. The setting of the spiral soft wire 43 facilitates the movement of the arc-shaped rubber sheet 56 and the electric contact metal sheet 44, and can ensure the electrical connection of the circuit. At this time, the electric contact metal sheet 44 and the built-in wire 42 of the auxiliary assembly 6 are in electrical connection with the multi-core wire 41. The electric contact metal sheet 44, the spiral soft wire 43 and the built-in wire 42 of the clamping assembly 5 are in electrical connection with the multi-core wire 41. Data transmission is performed between the multi-core wire 41 and the external soft wire 2 and the early warning device body 1, so that the early warning device body 1 can detect abnormal conditions such as voltage fluctuation, frequency deviation and harmonic. After the detection is completed, press the other button 32 to reset the clamping assembly 5 and the electric contact assembly 4, so that the device can be away from the circuit. As described above, when the device monitors the power quality parameters of the circuit, it can not only ensure the safety of the operator, but also ensure the stability and constant force of the contact between the device and the circuit, and improve the accuracy of the monitoring data.
