When using the discharge component 34, The discharging speed can be adjusted according to the different cracks in the road surface. During adjustment, the rotating block drives the micro screw 345 to rotate, so that the micro screw 345 pushes the baffle plate 344 close to the support seat 341, so as to realize the control of the concrete discharging speed, so that the concrete filler can more fully fill the road surface cracks through the guide plate 343. At the same time, the top outer wall of the discharge nozzle 342 and the bottom inner contact point of the guide tube 37 are provided with threads. Therefore, when the discharge nozzle 342 needs to be cleaned and replaced, it can be cleaned and replaced directly, which improves the practicality of the device. When the screw 35 drives the threaded plate 36 and the mounting plate 32 to move, the slider on one side of the mounting plate 32 moves synchronously on the slide rod surface, ensuring the synchronous movement of both sides of the mounting plate 32, thereby improving the stability of the device.
