When the adjustment gear 311 rotates, it will drive the second swing shaft column 308 to rotate. When the second swing shaft column 308 rotates, it will drive the swing arm 4 to swing up and down. When the swing arm 4 swings up and down, it will synchronously drive the monitoring module 5 clamped and fixed by the clamping box 407 to swing up and down to adjust the magnetic installation position, so that the monitoring module 5 can realize the safety monitoring of blasting excavation of the high-voltage line tower, and it is convenient to adjust the magnetic installation position of the monitoring module 5, so as to further improve the efficiency of the safety monitoring of blasting excavation of the high-voltage line tower;

[0038] At the same time, when the swing platform 2 swings backward, the connecting rod 110 will support the swing platform 2 in a swinging manner, so that the swing platform 2 swings backward for storage. When the connecting rod 110 supports the swing platform 2 in a swinging manner, the buffer column 108 cooperates with the support spring 109 to provide buffer support for the swing platform 2. When the swing platform 2 swings backward for storage, the swing platform 2 presses and contacts the contact switch 111. When the swing platform 2 presses and contacts the contact switch 111, the contact switch 111 will control the first drive motor 113 to stop rotating. When the first drive motor 113 stops rotating, the swing platform 2 can stop swinging backward, thereby facilitating the swing platform 2 to swing backward for storage.
