The connecting block 147 drives the camera 148 to move up and down. The camera 148 takes a photo of the side of the bridge with the fixed ruler 151 and the extension ruler 152 fitting with the side. Then, the rear button 133 is pressed according to the appropriate position to stop the motor 142 and stop the camera 148 at the appropriate position. Then, the middle button 133 is pressed to take pictures for evidence collection. The picture displayed by the camera 148 is displayed on the display 132. The readings of each layer of the bridge on the scale are n1, n2, n3... from top to bottom. The actual thickness of the xth layer is n x =n x -n x-1 , so as to obtain the thickness of each layer and record it, and save the measurement evidence by taking pictures, which is convenient for subsequent evidence-keeping work; it is convenient to read the scale without having to stretch your head to observe and lean your body out of the bridge, which improves the safety of the device and is simple to operate, saving time and effort.

The swivel seat 122 can rotate relative to the fixed seat 121. The swivel seat 122 is rotated 90° clockwise, and then the extension ruler 152 is rotated 180° counterclockwise. The spring clip 153 is bent to the right so that the extension ruler 152 can pass through the spring clip 153, and then the spring clip 153 is released. The elasticity of the spring clip 153 drives the spring clip 153 to reset. The spring clip 153 limits the extension ruler 152, making it convenient for the device to be folded and retracted.
