Description

Technical Field

[0001] The utility model relates to the technical field of green plant cold protection, in particular to a green plant maintenance and cold protection device. Background Art

[0002] Green plants such as woody and herbaceous flowering, foliage or fruit ornamental plants are often planted in gardens, green spaces and scenic spots. Some of these green plants have poor cold resistance and are easily frostbitten or frozen to death in winter, so they need to be protected from the cold. Cold covers are the most widely used cold protection devices. When used in the cold winter, cold covers protect green plants and other vegetation through certain measures to prevent frostbite and dry tips.

[0003] In order to facilitate transportation and storage, the supporting frames of the existing maintenance and cold-proof devices are mostly configured to be retractable. However, the design of the retractable mechanism of the supporting frame is still not reasonable, and the range of retraction is still small, resulting in the supporting frame still having a large volume in the retracted state, affecting portability.
