Problems solved by technology

[0003] There are many lawns in the garden, which are the places where the public likes to play. Some lawns are often played on by people, so that the surface of the lawn will become dense, which is not conducive to the breathing of grass roots. When it rains, it will loosen the land and improve The air permeability of the ground surface, but in a relatively dry climate, it is necessary for the garden staff to drill holes on the lawn to increase the air permeability of the lawn surface. A punching device is required for punching holes. The existing punching devices are often It is manual, the tines are connected through the mounting plate and the handle, and the efficiency is very low when people hold the handle to punch holes, and the tines are in rigid contact with the ground, which will seriously damage the tines
