[0053] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, the support structure 6 includes an arc-shaped mounting seat 61, an L-shaped mounting seat 63, a main cone 64, a pedal 65 and a sub-cone 66. The arc-shaped mounting seat 61 is circumferentially distributed at the bottom of the clamp A1 and the clamp B2 and is connected thereto as a whole by fixing bolts.

[0063] In this embodiment, in the initial state, the joint control unit 93 is separated from the arc-shaped rotating seat 91, and the arc-shaped rotating seat 91 rotates to the outside of the sub-guard plate 5;

[0064] When it is necessary to connect multiple sub-guard plates 5 as a whole, rotate the arc-shaped rotating seat 91 and make it rotate to a position close to the adjacent arc-shaped rotating seat 91, place the linkage control 931 at the bottom of the two groups of arc-shaped rotating seats 91 and make the connecting pieces 932 at both ends pass through the connecting holes 911 on the two groups of arc-shaped rotating seats 91 respectively, and then place the engaging piece 933 above the two groups of arc-shaped rotating seats 91 and engage it on the connecting piece 932, so as to connect the two groups of arc-shaped rotating seats 91 as a whole, and then connect multiple sub-guard plates 5 as a whole, so that multiple circumferentially distributed sub-guard plates 5 can move up and down at the same time, reducing the adjustment time, and enabling the sub-guard plates 5 to form a closed-loop clamp on the trunk of the tree, thereby increasing the stability of the connection between it and the tree and reducing the risk caused by looseness or misalignment.

[0065] In a preferred embodiment, the sub-guard plates 5 can be freely disassembled and assembled from the main guard plates 4, so that it can be suitable for effectively supporting trees of different specifications. The number and position of the sub-guard plates 5 can also be independently adjusted according to the actual supporting environment and under the premise of ensuring effective support for the trees, so as to achieve flexible adjustment of the bracket and improve its practicality and versatility. The sub-guard plates 5 can adopt arc plates of various thicknesses to meet the needs of supporting trees of different specifications, and can also effectively support trees with uneven trunk surfaces, or sub-guard plates 5 of uniform thickness can be adopted. In actual use, if trees with uneven trunk surfaces or trees of different specifications are encountered, and the supporting area of ​​the supporting structure 6 needs to be flexibly adjusted, a foam board or template of corresponding thickness can be inserted between the sub-guard plates 5 and the tree trunk to fill the space between the sub-guard plates 5 and the tree trunk, ensuring that the tree trunk can be effectively connected to the sub-guard plates 5, thereby improving the support quality of the tree trunk.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
