[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 The adjustable support frame for improving the survival rate of seedlings shown in the figure comprises a fixing ring 1, the fixing ring 1 is a split structure, the four sides of the bottom end of the fixing ring 1 are fixedly connected with nail rods 2, the fixing ring 1 and the ground are connected by setting the nail rods 2, a first through hole 3 is passed through the fixing ring 1, and an adjusting rod 4 is inserted into the first through hole 3, an adjusting ring 5 is threadedly connected to the adjusting rod 4, and rotating the adjusting rod 4 can drive the connecting frame 6 to move, so as to adapt to the bottom side trunk of the seedling, the adjusting ring 5 is rotatably connected to one side of the fixing ring 1 through a bearing, one end of the adjusting rod 4 is rotatably connected to the connecting frame 6 through a bearing, and one end of the connecting frame 6 is fixedly connected A stopper 20 is connected, and the stopper 20 is made of rubber. It provides cushioning by contacting the trunk of the seedling to adapt to the extension of the seedling, and at the same time solves the problem of increasing trunk diameter when the seedling grows. The bottom end of the connecting frame 6 is rotatably connected to the contact wheel 7 through a rotating shaft, and the upper end of the connecting frame 6 is fixedly connected to a fixing sleeve 8, and the upper end of the fixing sleeve 8 is threadedly connected to a screw 9, and an arc block 10 is rotatably connected to the screw 9. Rotating the screw 9 makes the arc block 10 move upward, so as to adapt to the change in height when the seedling grows. A through hole is opened on the arc block 10 and an elastic band 11 is inserted in the through hole, and the two ends of the elastic band 11 are fixedly connected by Velcro 12.

[0018] The trunk of the tree corresponds to the buffer block 16, and the buffer block 16 is glued to the inner side of the arc block 10. By setting the buffer block 16 to contact the trunk of the seedling, the wear and tear of the seedling during growth can be reduced.

[0019] Among them, the upper side of the fixing ring 1 is fixedly connected to the limiting sleeve 17, the limiting sleeve 17 is fixedly connected to one end of the first spring 15, the first spring 15 is sleeved on one side of the protrusion 14, the protrusion 14 is welded to the bottom end of the spring rod 13, and the spring rod 13 is fixedly connected to the outside of the arc block 10. By setting the spring rod 13, it can adapt to the adjustment between the fixing sleeve 8 and the screw rod 9 and provide support. At the same time, it can also adapt to the growth of seedlings and provide buffering.

[0020] One side of the connection frame 6 is fixedly connected to an auxiliary rod 18, and the auxiliary rod 18 is movably plugged into the fixed ring 1. By providing the auxiliary rod 18, the connection frame 6 can be limited so that the connection frame 6 can move linearly.

[0021] The adjusting rod 4 contacts the ball 19, and the ball 19 is rotatably embedded in the first through hole 3 of the fixing ring 1. By providing the ball 19, the friction between the adjusting rod 4 and the first through hole 3 is reduced, which facilitates the rotation stability of the adjusting rod 4.

[0022] Working principle: the fixed ring 1 is in a split structure so that the fixed ring 1 is connected to the seedling, and then the adjusting rod 4 is rotated to make the connecting frame 6 and the stopper 20 contact the bottom side of the seedling trunk, and then the arc block 10 is made to correspond to the trunk part of the seedling according to the height of the seedling, and then the elastic band 11 is used for limiting. At this time, the spring rod 13 and the first spring 15 provide adaptability. When the diameter of the seedling trunk increases, the stopper 20 and the buffer block 16 will be squeezed, so that the support effect of the seedling trunk is better, which is convenient for the seedling to maintain the correct growth direction. At the same time, it has a certain buffer, which increases the maintenance gap of the support frame, improves the adjustment adaptability of the support frame, and thus improves the survival rate of the seedling.
