In this embodiment, the metal tongue 2 is an arch structure, and the protruding position points to the inner direction, so that the wire 3 can be conveniently clamped and fixed.
The metal clamping tongues 2 are provided with monitoring modules 5, and the number of the monitoring modules 5 is 1, and the monitoring modules are positioned on a single metal clamping tongue 2. The side surface of the monitoring module 5 is provided with a metal elastic sheet 51 and a metal lead 53, and the metal elastic sheet 51 is insulated from the shell of the monitoring module 5 and has good conductivity, toughness and elasticity. The monitoring module 5 is fixed to the metal clip tongue 2 by a metal lead 53. The metal clip tongue 2 is provided with a hole 21 for the metal elastic sheet 51 to pass through, and the metal elastic sheet 51 is not in contact with the metal clip tongue 2. The monitoring module 5 is provided with a pressure sensor 52 in contact with the metal elastic sheet 51, and the pressure sensor 52 is used for detecting the deformation degree of the metal elastic sheet 51 after the wire 3 is in contact with the metal elastic sheet 51 and reflecting the good hanging degree of the wire 3.
The monitoring module 5 is internally provided with a singlechip 54, a wireless communication module 55 and a power supply 56, wherein the wireless communication module 55 is a 433 wireless communication module, the power supply 56 is a battery, and the voltage is 3V. The pressure sensor 52 is in communication connection with the single chip microcomputer 54, and the single chip microcomputer 54 is in communication connection with the wireless communication module 55. A pressure detection threshold is preset in the single chip microcomputer 54, when a threshold conduction signal is detected, an instruction is immediately sent to the wireless communication module 55, and the wireless communication module 55 transmits a wire connection signal.
The power supply 56 supplies power to the pressure sensor 52, the singlechip 54 and the wireless communication module 55 through a power supply loop. A virtual on-off switch is arranged on the power supply loop, such as SW1 in fig. 4, specifically, a breakpoint is arranged on the power supply loop, two ends of the breakpoint are electrically connected with the metal elastic sheet 51 and the metal lead 53 respectively, when the wire 3 is clamped between the two metal clamping tongues 2, the metal elastic sheet 51, the wire 3, the metal clamping tongues 2 and the metal lead 53 are sequentially electrically communicated to realize the connection of the breakpoint, the whole power supply loop is in a communication state, and at this time, the pressure sensor 52, the single chip 54 and the wireless communication module 55 are powered on and are in a working state.
