[0002] Apples are one of the most widely grown and sold fruits in my country, with a long history of cultivation and a wide distribution. In terms of cultivation techniques, apple trees are propagated through various techniques such as grafting, layering, sowing, and tissue culture.

[0003] Grafting is the most common and effective method to ensure that the new plant retains all the characteristics of the mother tree. During grafting, after the grafting branch is grafted onto the rootstock, multiple layers of film or tape are usually used to firmly fix the grafting branch to the rootstock.

[0004] However, the fixing effect of film or tape is generally not good. Later, due to interference from various external environmental factors, the grafted branches are prone to falling off or loosening, leading to grafting failure. Utility Model Content

[0014] The clamping members on the second and first fixing parts clamp and fix the apple tree branches from three directions in a circumferential manner, which is suitable for apple tree branches with smaller diameters.

[0015] Preferably, the connecting rod is a self-locking telescopic rod, which is set on the first fixed plate, the second fixed plate and the third fixed plate. Each set of clamping components is provided with a connecting rod on both sides, so as to facilitate the adjustment of the distance between the two sets of fixing devices so that the clamping components are in a suitable clamping position.

[0032] The ring structure surrounds the apple tree branch, and the clamping component 3 on the ring structure also surrounds the apple tree branch. By adjusting the clamping component 3, the grafting position can be fixed in a ring manner.

[0033] The clamping component 3 includes a rotating cylinder 301 rotatably connected to the first or second fixing part. A threaded rod 302 is internally threaded onto the rotating cylinder 301. A clamping plate 303 is fixedly installed on one end of the threaded rod 302 within the annular structure. The clamping plate 303 is arc-shaped with a central angle of less than 45° to allow for adaptive adjustment according to the diameter of the apple tree branch. An elastic soft pad 304 is provided on the inner side of the clamping plate 303 to protect the apple tree branch. Multiple clamping plates 303 surround and clamp the apple tree branch. Guide rods 305 are also slidably inserted into both sides of the rotating cylinder 301 on the first and second fixing parts. The guide rods 305 are fixedly connected to the outer side of the clamping plate 303.

[0034] Rotating the rotating drum 301 can cause the threaded rod 302 to move inward relative to the first or second fixed part, thereby causing the clamping plate 303 to approach the apple tree branch. Multiple clamping plates 303 are in close contact with the apple tree branch, forming a clamp at the grafting position.

[0035] In this embodiment, the second fixing part and the first fixing part have the same shape and structure. The first fixing part includes a first fixing plate 101 and a second fixing plate 102 that are fixedly connected.

[0038] The clamping members 3 on the second fixing part and the first fixing part clamp and fix the apple tree branch from three directions in a circumferential manner, which is suitable for apple tree branches with small diameter.

[0039] In this embodiment, the connecting rod 2 is a self-locking telescopic rod. The connecting rod 2 is set on the first fixing plate 101, the second fixing plate 102 and the third fixing plate 103. Each set of clamping components 3 is provided with a connecting rod 2 on both sides, which facilitates the adjustment of the distance between the two sets of fixing devices 1 so that the clamping components 3 are in a suitable clamping position.

[0040] In this embodiment, the outer periphery of the rotating drum 301 is provided with anti-slip texture to facilitate the operation of the rotating drum 301 and prevent slippage. The threaded rod 302 and the guide rod 305 are provided with a limit block at one end outside the annular structure to limit the threaded rod 302 and the guide rod 305.

[0041] In this embodiment, the internal thread on the rotating drum 301 and the external thread on the threaded rod 302 are both single-threaded threads, which have self-locking ability and good fixing effect.

[0042] In use, the first and second fixing parts can be separated by disengaging the latch lock. Then, the first and second fixing parts can be wrapped around the apple tree branch and then fixedly connected by the latch lock.

[0043] The ring structure surrounds the apple tree branch, and the clamping component 3 on the ring structure also surrounds the apple tree branch.

[0044] Rotating the drum 301 can drive the threaded rod 302 to move inward relative to the first or second fixed part, thereby driving the clamping plate 303 closer to the apple tree branch.

[0045] Repeat the above operation to adjust the multiple clamping components 3 so that the multiple clamping plates 303 on the first fixing part and the second fixing part are tightly attached to the apple tree branches and trunk, forming a clamping and fixing of the grafting position.
