When greening a park, it is necessary to regularly fertilize, water, and trim the trees, lawns, and flowers inside. Among them, the lawn cutting and weeding process is very important. A more common and economical method is to use a handheld park greening weeding device. The advantage of this device is that it is light in weight, easy to carry, and inexpensive, which can reduce the cost of greening maintenance.

[0003] In the prior art, a Chinese patent with patent announcement number CN213718744U discloses a weeding device for park greening, including a switch, a docking groove, a cutting blade and a rod body, a handle is sleeved on the top of the rod body, and a switch is installed on the outer wall of the handle, and a force-applying structure is movably connected on the outer wall of the rod body, and the force-applying structure includes a protective pad, a grip rod, a fixing bolt, a mounting groove and a notch. When the above weeding device is in use, the lawn is trimmed by the cutting blade. When trimming, the height of the lawn can only be controlled by the operator's hand, which will cause the grass on the lawn to be trimmed too short or at different heights, affecting the neatness of the lawn after trimming. Therefore, we disclose a weeding device for garden greening maintenance and afforestation to meet the needs. Utility Model Content
