[0013] (1) Through the designed rotating column, sleeve, connecting rod, mounting tube and swing rod, the nozzle is rotatably connected to the present invention through the rotating column and sleeve, and the swing rod is assembled at the front end of the nozzle through the mounting tube and the connecting rod. When the road maintenance asphalt repair is carried out, one end of the swing rod is placed in the gap of the road. When the present invention is pushed to migrate and lay asphalt, the swing rod moves along the gap as a path, and the swing rod swings along with the bending change of the gap, thereby driving the nozzle to swing at the same time, so that the nozzle is automatically aligned with the gap. Compared with the traditional manual adjustment of the nozzle position, the road maintenance asphalt repair is more convenient. It is more maneuverable and flexible. Through the designed connecting studs and connecting screw holes, the mounting tube equipped with the rocker arm is matched with the connecting studs and connecting screw holes, and can be quickly disassembled onto the connecting rod, so that when the rocker arm is worn, the rocker arm can be disassembled and replaced. The designed limit blocks and limit holes can limit the rocker arm to prevent it from falling off from the mounting tube. The designed ball bearings rotate on the lower surface of the ball bearings to provide lubrication effect, reducing the influence of friction resistance between the rotating column and the sleeve. The designed spring applies elastic force to the rocker arm to prevent the rocker arm from jumping too flexibly during construction and affecting the guiding effect.
