The U-shaped plug rod is prevented from falling out of the positioning plug hole during the connection of the side template of the road and bridge construction. When it is necessary to connect the adjacent side templates horizontally, the U-shaped plug rod is pulled out of the positioning plug hole. Take it out from the socket, rotate the rotating seat plate to make the planes of the two rotating seat plates fit together, then insert the U-shaped card plate into the slot, and use the U-shaped card plate to make the two rotating seat plates fit closely together, thereby ensuring that adjacent side templates remain horizontally aligned, and the symmetrical positioning columns are magnetically connected. The positioning columns are used to prevent the U-shaped card plate from falling out of the slot during the connection of the side templates of road and bridge construction, thereby ensuring the connection between the U-shaped card plate and the symmetrical rotating seat plates. This device can make adjacent side templates connected horizontally or vertically by rotating the rotating seat plate, and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
