[0001] The present application relates to the technical field of forestry equipment, in particular to a tree supporting device for forestry planting. BACKGROUND

[0002] In forestry planting, newly transplanted seedlings or trees often suffer from natural disasters such as storms and human damage because the root system has not yet completed growth. Therefore, it is necessary to use reinforcing methods to support and protect the trees, resist strong winds or other external pressures, provide stable support, and help the trees maintain an upright position to prevent lodging.

[0003] The existing tree supporting device for forestry planting is usually bundled and supported by a wooden frame. When strong winds occur, the existing device can fix the trees too tightly, which limits the natural buffering capacity of the trees and causes the trees to be blown off. SUMMARY
