[0041] When it is necessary to repair cracks in roads and bridges, first, the handle 7 is moved by external force, and the movement of the handle 7 drives the shell 1 to move, and the moving nozzle 3 of the shell 1 moves to the crack, and then the electric telescopic rod 2 is started by the battery 5 to drive the U-shaped scraper 19 to contact the ground.

[0042] Then, the pull rod handle 8 is pulled by external force, and the movement of the pull rod handle 8 drives the spring 9 to be compressed, and the movement of the pull rod handle 8 drives the pull rod 10 to move, and the movement of the pull rod 10 drives the push block 11 to move, pushing the material inside the shell 1 through the connecting pipe 6 into the interior of the nozzle 3 and finally flowing into the crack, and then the pull rod handle 8 is released, the spring 9 is reset and drives the pull rod handle 8 to move, and the movement of the pull rod handle 8 drives the push block 11 to move until the feed hole 12 is located in front of the front surface of the push block 11, and the repair material inside the repair liquid container 4 enters into the interior of the shell 1 through the feed hole 12 for replenishment, and by setting a push block 11 of a reasonable size, the push block 11 can completely close the feed hole 12 when it moves inside the shell 1 to push the material, and the feed hole 12 will be exposed only when the push block 11 moves backward.
