[0013] By adopting the above technical solution, when the staff slides the slide bar in the direction close to the tree, the abutting plate slides in the direction close to the tree under the action of the slide bar, and then the side wall of the abutting plate abuts against the side wall of the tree, and then the installation rod slides in the direction away from the tree under the action of the abutting plate, so that the placement plate slides in the direction away from the tree under the action of the installation rod. At this time, when the staff stops sliding the slide bar, the placement plate slides in the direction close to the tree under the action of the second spring, and then the installation rod slides in the direction close to the tree under the action of the placement plate, so that the abutting plate moves in the direction close to the tree under the action of the installation rod, and then the side wall of the abutting plate abuts against the side wall of the tree, thereby improving the fixing effect of the device and thereby improving the practicality of the device.

[0033] When the staff needs to fix the tree, the staff needs to rotate the first threaded rod 13, so that the two mounting blocks 12 are separated from each other. Then, the staff needs to rotate the two fixing rings 1, so that the two connecting blocks 11 rotate with each other, so that the two fixing rings 1 are separated from each other. At this time, the staff needs to sleeve the two fixing rings 1 on the tree. Then, the staff needs to rotate the fixing rings 1 in the opposite direction, so that the two connecting blocks 11 rotate relatively under the action of the fixing rings 1, so that the two fixing rings 1 abut against each other. At this time, the staff needs to rotate the first threaded rod 13 in the opposite direction, so that the two mounting blocks 12 abut against each other under the action of the first threaded rod 13, and then, the staff needs to slide the slide bar 14 in the direction close to the tree, so that the abutting block 32 slides in the direction close to the tree under the action of the slide bar 14, so that the abutting plate 15 abuts against the side wall of the tree under the action of the slide bar 14.

The second threaded rod 33 is threadedly arranged on the upper surface of the fixing ring 1, and its axis is vertical, and the second threaded rod 33 is rotatably connected to the fixing block 31.

[0035] When the staff needs to fix the slide bar 14, when the staff needs to fix the slide bar 14, the staff needs to rotate the second threaded rod 33, thereby making the second threaded rod 33 move downward, so that the fixing block 31 slides downward under the action of the second threaded rod 33, thereby making the fixing block 31 gradually approach and finally press against the first inclined surface 34, so that the pressing block 32 slides in the direction close to the slide bar 14 under the action of the fixing block 31, and then makes the pressing block 32 slide in the direction close to the slide bar 14 under the action of the fixing block 31, so that the side wall of the pressing block 32 presses against the side wall of the slide bar 14, thereby reducing the probability of the slide bar 14 sliding when subjected to external force, thereby improving the stability of the device, thereby reducing the difficulty of the staff in fixing the slide bar 14, thereby improving the work efficiency of the staff.

[0036] A reset groove 24 is provided on the inner top wall of the abutting groove 22. The reset block 4 is a rectangular block structure. The reset block 4 is slidably arranged in the reset groove 24, and the bottom surface of the reset block 4 is fixed to the upper surface of the abutting block 32. One end of the first spring 41 is fixedly arranged on the side wall of the reset block 4 close to the second threaded rod 33, and the other end of the first spring 41 is fixedly arranged on the inner wall of the reset groove 24 close to the second threaded rod 33.

[0037] When the fixed block 31 and the first inclined surface 34 are separated from each other, the reset block 4 slides in the direction away from the slide rod 14 under the action of the first spring 41, and then the clamping block 32 slides in the direction away from the slide rod 14 following the reset block 4 under the action of the reset block 4, so that the first inclined surface 34 is opposite to the fixed block 31, thereby reducing the difficulty for the staff to reset the clamping block 32, thereby reducing the difficulty of the staff's work.

[0038] The side walls of the two sliding rods 14 that are close to each other are provided with mounting grooves 25, and the inner walls of the two mounting grooves 25 that are away from each other are provided with placement grooves 26.

At this time, when the staff stops sliding the slide bar 14, the placement plate 51 slides toward the tree under the action of the second spring 52, so that the installation rod 5 slides toward the tree under the action of the placement plate 51, so that the abutting plate 15 moves toward the tree under the action of the installation rod 5, so that the side wall of the abutting plate 15 abuts against the side wall of the tree, thereby improving the fixing effect of the device and thereby improving the practicality of the device.

[0040] The support block 6 is a rectangular block structure, and there are four support blocks 6 symmetrically arranged on the side walls of the two fixing rings 1 away from each other, and the axes of the four support blocks 6 are perpendicular to each other. The support rod 61 is a rectangular rod structure, and there are four support rods 61 fixedly arranged on the bottom surfaces of the four support blocks 6 respectively.

[0041] When the staff needs to fix the fixing ring 1, the staff needs to insert the support rod 61 into the ground, thereby reducing the probability of the support device shaking during operation, thereby reducing the probability of the fixing ring 1 shaking during operation, thereby improving the stability of the device.

[0044] In order to extend the life of the tree, the side walls of the two pressing plates 15 close to each other are fixedly provided with rubber sheets 8. The rubber sheets 8 reduce the probability of damage to the tree when the pressing plates 15 press against the tree, thereby extending the life of the tree.

[0045] In order to reduce the working difficulty of the staff, the upper surfaces of the two second threaded rods 33 are fixedly provided with handles 9. The handles 9 reduce the working difficulty of the staff to rotate the second threaded rods 33, thereby reducing the working difficulty of the staff.

[0046] The use principle of a garden tree support device in this embodiment is as follows: when the staff needs to fix the tree, the staff needs to rotate the first threaded rod 13, so that the two mounting blocks 12 are separated from each other. Subsequently, the staff needs to rotate the two fixing rings 1, so that the two connecting blocks 11 are rotated relative to each other, so that the two fixing rings 1 are separated from each other.

Subsequently, the staff needs to rotate the fixing rings 1 in the opposite direction, so that the two connecting blocks 11 are relatively rotated under the action of the fixing rings 1, so that the two fixing rings 1 are abutted against each other. At this time, the staff needs to rotate the first threaded rod 13 in the opposite direction, so that the two mounting blocks 12 are pressed against each other under the action of the first threaded rod 13, and then the staff needs to slide the slide bar 14 in the direction close to the tree, so that the pressing block 32 slides in the direction close to the tree under the action of the slide bar 14, so that the pressing plate 15 is pressed against the side wall of the tree under the action of the slide bar 14. The second threaded rod 33 is rotated by the staff, so that the second threaded rod 33 moves downward, so that the fixing block 31 slides downward under the action of the second threaded rod 33, so that the fixing block 31 gradually approaches and finally presses against the first inclined surface 34, so that the pressing block 32 slides in the direction close to the slide bar 14 under the action of the fixing block 31, so that the pressing block 32 slides in the direction close to the slide bar 14 under the action of the fixing block 31, so that the side wall of the pressing block 32 presses against the side wall of the slide bar 14, thereby reducing the probability of the slide bar 14 sliding when subjected to external force, thereby improving the stability of the device, thereby reducing the difficulty for the staff to fix the slide bar 14, thereby improving the work efficiency of the staff.
