At this time, press the push rod 18 downward to drive the movable rod 11 to move downward, and then push the sliding plate 14 downward through the first tooth block 12, thereby driving the tamping cone rod 15 to move downward, and realizing the tamping work of the concrete ground by manual operation. When large-area tamping work is needed, the shell 20 can be sleeved downward from the top of the handle 1, and the positioning insert rod 31 is inserted into the positioning insert hole 19. The shell 20 is positioned and supported by the supporting block 7, and then the shell 20 is positioned and installed by the threaded connection of the locking nut 32 and the positioning insert rod 31. Then, start the drive motor 28 to drive the cam 29 to rotate, and cooperate with the second spring 27 to realize the up-down movement of the movable plate 22, and at the same time, drive the pressing plate 24 to move up and down through the pull rod 23, and then realize automatic tamping work by pushing the push rod 18 and cooperating with the upward resetting effect of the sliding plate 14, thereby reducing the labor intensity of manual operation, and facilitating the disassembly of the shell 20 in the later period. Rotate the handle 39 to drive the adjusting screw 37 to rotate, which can adjust the height of the pressing column 38, and then adjust the height of the sliding plate 14. At this time, the device can be directly operated to realize the tamping work of the concrete ground, without pressing the push rod 18 each time, saving the operation steps and making the use more convenient. After the tamping of the concrete ground is completed, the shell 20 is removed, the handle 1 is rotated to adjust the operation angle of the handle 1 according to personal use requirements, and after the adjustment is completed, the positioning cover 17 is rotated on the handle 1 to move, and the movable rod 11 is driven to move through the resistance of the sliding rod 10, and then the first tooth block 12 is driven to move and engage with the arc-shaped tooth plate 8, thereby completing the angle positioning of the handle 1. At this time, the aluminum alloy scraper 2 is downward to flatten the tamped concrete ground, and the handle 1 is operated.
