The bridge mechanism as a whole can be adapted to connect two photovoltaic brackets with height difference and / or horizontal difference. When in use, the articulated rod 1, the telescopic rod 2 and the adapter 3 are locked and fixed, that is, after the bridge mechanism is installed and adjusted, it is fixed as a whole to prevent external environmental factors from interfering with it and changing the adjusted length and angle, thereby affecting the passage of the robot.
