The outside of the first camera connection end is connected to the camera module. When the vertical motor is activated, the vertical driving gear rotates, driving the vertical driven gear to rotate, causing the first camera connection end and the camera module attached thereto to rotate, thereby adjusting the pitch direction of the thermal imaging camera.

[0009] Preferably, a horizontal bearing cover is provided on the inward side of the horizontal bearing, and a vertical bearing cover is provided on the inward side of the vertical bearing.

[0010] Preferably, a horizontal rotation limiter is provided on the horizontal bearing cover, and a horizontal rotation limit ring with a diameter larger than the gear and a notch is provided on the horizontal driven gear.
