[0032] Refer to Figures 1-5, An orthosis, comprising a first pull rod 1 and a second pull rod 2. First, a first fixed rod 3 is fixedly arranged on one side of the first pull rod 1. The first fixed rod 3 is used to fix or support the position of the first pull rod 1 on the fruit tree. A first chute 101 is formed on the same side of the first pull rod 1 as the first fixed rod 3. A second fixed rod 4 is slidably connected in the first chute 101, so that the second fixed rod 4 can move along the first chute 101, thereby adjusting its position on the first pull rod 1.

[0033] At the same time, a second chute 201 is provided on one side of the second pull rod 2. The second chute 201 is on the same side as the first chute 101. A telescopic rod 5 is slidably connected in the second chute 201. One end of the telescopic rod 5 is fixedly connected to a first orthopedic rod 6. The first orthopedic rod 6 is on the same side as the first fixed rod 3 and is used for preliminarily orthopedic the fruit tree branches.

[0034] In order to further increase the flexibility and precision of orthopedics, a third chute 501 is also provided on the telescopic rod 5. A second orthopedic rod 7 is slidably connected in the third chute 501. A sliding hole is formed on one side of the second orthopedic rod 7. A second limiting ring 18 is fixedly arranged at the opening of the end of the sliding hole away from the telescopic rod 5, which is used to limit the sliding out of the components in the sliding hole.

[0035] In order to realize the angle adjustment between the first pull rod 1 and the second pull rod 2, an angle adjustment component is provided. The component includes an adjustment seat 10 fixed at one end of the second pull rod 2, and an inner hexagonal tube 11 fixedly connected through and near the end of the first pull rod 1 close to the second pull rod 2. Connecting holes are formed on both inner walls of the adjustment seat 10. The two ends of the inner hexagonal tube 11 are respectively located in the corresponding connecting holes and are rotatably connected to the connecting holes, thereby realizing the angle adjustment between the first pull rod 1 and the second pull rod 2.

[0036] In order to fix the angle after adjustment between the first pull rod 1 and the second pull rod 2, a first spring 12 is arranged inside the hexagon socket pipe 11. Both ends of the first spring 12 are fixedly connected with a hexagonal prism 13. Both hexagonal prisms 13 are slidably clamped with the inner wall of the hexagon socket pipe 11 and can move along the hexagon socket pipe 11 under the action of an external force. One end of both hexagonal prisms 13 away from each other is fixedly connected with a pressing block 14, and the diameter of the pressing block 14 is smaller than the inner diameter of the hexagonal prism 13 for easy operation. Hexagonal holes corresponding to the hexagonal prisms 13 are formed on both sides of the adjusting seat 10, and the two hexagonal holes are communicated with the corresponding connecting holes. When the hexagonal prism 13 moves along the hexagon socket pipe 11 into the hexagonal hole under the elastic force of the first spring 12, the locking between the first pull rod 1 and the second pull rod 2 is realized. At the same time, third limiting rings 19 are fixedly arranged at the positions of the two sides of the adjusting seat 10 at the hexagonal holes to prevent the hexagonal prism 13 from disengaging from the hexagonal hole. When the angle needs to be adjusted, press the two pressing blocks 14 to drive the two hexagonal prisms 13 to move inside the hexagon socket pipe 11, so that the hexagonal prism 13 disengages from the clamping with the hexagonal hole, and the first pull rod 1 and the second pull rod 2 can rotate to adjust the angle.

[0037] The limiting component adopts the cooperation mode of a limiting rod 15 and a limiting hole 502. The limiting rod 15 is located inside the sliding hole of the second orthopedic rod 7 and is slidably connected with the inner wall of the sliding hole. Both ends of the limiting rod 15 respectively extend to the outside of the sliding hole, and a plurality of limiting holes 502 are equidistantly arranged on one inner wall of the third sliding groove 501. When the distance between the first orthopedic rod 6 and the second orthopedic rod 7 needs to be adjusted, the limiting rod 15 can be pulled to make one end of it disengage from the corresponding limiting hole 502, so that when the second orthopedic rod 7 slides on the telescopic rod 5 to adjust the distance between the first orthopedic rod 6 and the second orthopedic rod 7.
