[0029] Signal strength adjustment assembly 7 includes shell 71, the sliding block 75 is slidably connected in shell 71, the one side fixed connection of sliding block 75 has elastic arc piece 73, and elastic arc piece 73 is fixedly connected with shell 71, and the top fixed connection of sliding block 75 has conducting strip 74, and the fixed connection of resistance rod 72 is fixedly connected in shell 71, and conducting strip 74 is connected with resistance rod 72, and the one side fixed connection of sliding block 75 away from elastic arc piece 73 has homopolar magnetic sheet 76, and the fixed connection of homopolar electromagnet 77 is fixedly connected in shell 71, and homopolar electromagnet 77 repels homopolar magnetic sheet 76, and signal receiving circuit module is electrically connected with homopolar electromagnet 77.

[0030] It can be understood that the input signal source, signal strength adjustment assembly 7, signal amplifier 51, signal receiver 4 and monitoring head 2 are connected in series, and the signal power of signal amplifier 51 is controlled by controlling the length of resistance rod 72 participating in power supply, so that the signal strength received by signal receiver 4 is in a stable state.

[0031] Please refer to Figure 2 And Figure 4 The one side electrically connected of conducting strip 74 has connecting line 713, and connecting line 713 is electrically connected with signal amplifier 51, and the wire connection groove is set in shell 71, and the wire connection groove has an inclined surface, and the fixed connection of counterweight 714 is fixedly connected in connecting line 713, and counterweight 714 is slidably connected with the inclined surface.

[0032] It can be understood that when sliding block 75 moves away from homopolar electromagnet 77, connecting line 713 used for connecting other devices will be moved, and the movement of connecting line 713 will drive counterweight 714 to slide on the inclined surface, and when sliding block 75 moves close to homopolar electromagnet 77, the movement of connecting line 713 is pulled by the weight of counterweight 714, avoiding the partial blockage of connecting line 713 between sliding block 75 and homopolar electromagnet 77 from affecting use.

[0033] Please refer to Figure 2The shell 71 is rotationally connected with a direction changing wheel 710, and a connecting line 713 is slidably connected with the direction changing wheel 710.
