[0002] Camellia oleifera, also known as tea seed tree, tea oil tree, and white flower tea, belongs to the Theaceae family and is an evergreen shrub or small tree. It is named for the oil that can be extracted from its seeds for consumption. Camellia oil is clear, fragrant, nutritious, and has a long shelf life, making it a high-quality edible oil. It can also be used in industry as a lubricant and rust inhibitor. The tea cake is used as both a pesticide and a fertilizer, improving the water retention capacity of farmland and controlling pests in rice paddies. The fruit peel is a raw material for extracting tannin. When planting Camellia oleifera trees, grafting is performed on the branches, requiring the use of grafting devices.

[0003] Existing grafting devices for camellia oleifera planting mostly use tape to directly fix the branches together after grafting. In windy weather, the grafted branches are prone to shaking and easily fall off, leading to grafting failure. Therefore, a device is needed to help solve this problem. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model utilizes the cooperation between a fixed sleeve, a fixed strap, an adjusting gear, and a positioning component. By rotating the fixed ring, the fixed ring drives the fixed column to rotate as a whole, which in turn drives the adjusting gear to rotate as a whole. When the adjusting gear rotates, it meshes with the outer side of the through hole, thereby achieving overall movement of the through hole. This allows the fixed sleeve and fixed strap to be stably fixed to the branch according to the different overall dimensions of the grafted branches, ensuring that the two branches at the grafting point can be stably fixed. In windy weather, this design can prevent the grafted branches from shaking and causing grafting failure.

[0018] This utility model, through the cooperation between the positioning components and positioning holes, pulls the fixing ring, which in turn moves the fixing plate as a whole. When the fixing plate moves, the fixing post is pulled, and when the fixing post is pulled, the return spring is compressed. When the fixing post is pulled, the positioning pin is completely withdrawn from the positioning hole. This ensures that the through hole is at the corresponding length after the position of the through hole is adjusted. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a branch grafting device for planting camellia trees, such as... Figure 1-4As shown, the grafting device for planting camellia trees includes a fixing sleeve 1. A fixing band 2 protrudes from the side of the fixing sleeve 1. The fixing band 2 is strip-shaped. A through hole 4 is horizontally opened on the fixing sleeve 1. The fixing band 2 is installed through the through hole 4. A protruding seat protrudes from the outer side of the fixing sleeve 1. A rotating cavity is opened inside the protruding seat. The rotating cavity is connected to the through hole 4. An adjusting gear 8 is rotatably installed in the rotating cavity. A meshing tooth protrudes from the outer side of the fixing band 2. The meshing tooth meshes with the adjusting gear 8. A positioning cavity is opened inside the adjusting gear 8. A positioning device is installed in the positioning cavity. Positioning component 9 includes a slidably mounted fixed post 10, with the top of the fixed post 10 extending into a positioning cavity. A fixed plate is fixed to one end of the fixed post 10 extending into the positioning cavity. The fixed plate is embedded in the top of the fixed sleeve 1. A fixed ring 13 is fixed to the top of the fixed plate. A return spring 11 is installed inside the positioning cavity to assist the fixed post 10 in pushing and pressing. A positioning pin 12 is fixed to one end of the fixed post 10 away from the fixed plate. The positioning pin 12 and the positioning hole are both in a plum blossom shape. The positioning pin 12 and the positioning hole cooperate for positioning. A positioning hole is opened at the bottom of the rotating cavity. The positioning hole cooperates with the positioning component 9 for positioning.

[0027] By cooperating with the fixed sleeve 1, the fixed strap 2, the adjusting gear 8, and the positioning component 9, the fixed ring 13 is rotated. The fixed ring 13 drives the fixed column 10 to rotate as a whole, and drives the adjusting gear 8 to rotate as a whole. When the adjusting gear 8 rotates, it meshes with the outer side of the through hole 4, thereby realizing the overall movement of the through hole 4. Then, according to the different overall dimensions of the grafted branches, the fixed sleeve 1 and the fixed strap 2 are stably fixed on the branches, thus ensuring that the two branches at the grafting point can be stably fixed. In windy weather, it can ensure that the grafted branches will not sway and cause grafting failure.

[0028] The aforementioned fixing post 10 has a rectangular rod-like structure. The through hole on the fixing sleeve 1 corresponding to the fixing post 10 is circular. By making the fixing post 10 a rectangular rod-like structure, it can be ensured that the fixing post 10 can drive the adjusting gear 8 to rotate as a whole when rotating. By setting the through hole to be circular, the adjusting gear 8 can still rotate as a whole even after the fixing post 10 extends out.

[0029] The inner side of the aforementioned fixing sleeve 1 is provided with a insertion groove 7. A connecting plate 6 is installed between the two fixing sleeves 1. The top and bottom of the connecting plate 6 are provided with protruding blocks 5. The protruding blocks 5 and the insertion groove 7 are fitted together. Both the protruding blocks 5 and the insertion groove 7 are I-shaped. A fixing bolt 61 is threaded on the protruding block 5. A fixing hole 71 is provided at the insertion groove 7. The protruding block 5 and the fixing hole 71 are fitted together for positioning.

[0030] A protective layer 3 is embedded on the inner side of the fixing belt 2. Several clamping pads are protruding on the inner side of the protective layer 3. Through the cooperation between the protective layer 3 and the clamping pads, damage to the branches can be avoided as much as possible during the clamping operation.

[0031] Working principle:

[0032] During operation, after the branch is grafted, the fixing strap 2 is inserted into the through hole 4. Pulling the fixing ring 13 causes the fixing plate to move as a whole. When the fixing plate moves, the fixing post 10 is pulled. When the fixing post 10 is pulled, the return spring 11 is compressed. When the fixing post 10 is pulled, the positioning pin 12 is completely removed from the positioning hole.

[0033] Rotating the fixing ring 13 causes the fixing column 10 to rotate as a whole, which in turn causes the adjusting gear 8 to rotate as a whole. When the adjusting gear 8 rotates, it meshes with the outer side of the through hole 4, thereby realizing the overall movement of the through hole 4. Then, according to the different overall dimensions of the grafted branches, the fixing sleeve 1 and the fixing strap 2 are stably fixed on the branches, thus ensuring that the two branches at the grafting point can be stably fixed and minimizing problems such as branch shaking.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
