By setting the limiting plate 18, the tooth plate 6 can be limited to prevent the tooth plate 6 from shaking during movement.

[0037] Working principle: when in use, when the user needs to adjust the length of the rake handle 1, the push-pull plate 20 and the toothed plate 6 are pulled upwards, the toothed plate 6 drives the gear 8 to rotate, and at the same time the push-pull plate 20 stretches the elastic belt 7, the gear 8 drives the worm 9 to rotate, and the worm 9 drives the gear plate 10 to rotate with the transmission rod 11 as the center, and the gear plate 10 pushes the T-shaped card plate 12 to move to the side away from the slot 4 through the push rod 14. After the T-shaped card plate 12 moves to the appropriate position, the T-shaped card plate 12 disengages from the slot 4. At this time, the extension rod 3 is disengaged from the fixed state, and the user can adjust the length of the extension rod 3. After the height adjustment of the connecting plate 22 is completed, the toothed plate 6 is loosened, and the elastic belt 7 drives the T-shaped card plate 12 to re-enter the slot 4 to fix the extension rod 3 through its own elastic force. When the soil on the surface of the rake nail 2 needs to be cleaned, the bolt 15 is loosened, and the scraper 16 is driven forward by the push plate 17 to clean the soil on the surface of the rake nail 2.
