Technical Field
[0001] This utility model belongs to the field of pine grafting technology, specifically relating to a five-needle pine grafting fixing component. Background Technology
[0002] Grafting is one of the artificial methods of propagating plants through nutrition. It is widely used in fruit trees, flowers, and other plants. Common grafting methods include bud grafting, branch grafting, and approach grafting. During the grafting process, the cuts of the rootstock and scion need to be aligned and fixed so that they can heal and form a whole, thus completing the grafting.
[0003] Traditional methods of fixing grafts often involve wrapping the rootstock and scion with ropes and plastic film. This method is generally ineffective, and the plastic film is easily blown off by the wind, which can lead to the separation of the rootstock and scion. Therefore, we propose a grafting fixation device for five-needle pine. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a five-needle pine grafting fixing component, so as to solve the problem that the traditional fixing method mentioned in the background art is often to use rope and plastic film for wrapping and fixing. This fixing method has a generally poor fixing effect, and the plastic film is easy to fall off when blown by the wind, which leads to the separation of the rootstock and scion and is inconvenient to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a five-needle pine grafting fixing component, comprising a fixing plate, rotating shaft seats fixedly connected to both sides of the fixing plate, a rotating shaft I fixedly connected to the surface of the rotating shaft seats, two sets of clamping straps rotatably connected to the surface of the rotating shaft I, a strap fixedly connected to the surface of one set of clamping straps, a plurality of locking blocks I fixedly connected to the surface of the strap, and an engaging structure provided on the surface of the other set of clamping straps, the engaging structure including a fixing block, a groove formed on the surface of the fixing block, and a rotating shaft II fixedly connected to the inner wall of the groove. A rotating plate is rotatably connected to the outer side of the rotating shaft two. A locking block two is fixedly connected to the surface of the rotating plate. A spring one is fixedly connected to the surface of the rotating plate. A locking groove is opened on the inner side of the groove. A sliding groove one is opened on both sides of the fixing block. An auxiliary structure is provided on the surface of the fixing plate. The auxiliary structure includes a sliding groove two. A limiting block is slidably connected inside the sliding groove two. A connecting rod is fixedly connected to the surface of the limiting block. A spring two is sleeved on the outer side of the connecting rod. An anti-slip pad layer is fixedly connected to the surface of the connecting rod. A placement groove is opened on the surface of the anti-slip pad layer.
[0006] Preferably, the two ends of the spring one are fixedly connected to the inner wall surface of the groove and the surface of the rotating plate, respectively, and the rotating plate is a rotatable structure on the rotating shaft two.
[0007] Preferably, the cross-sections of both the first card block and the second card block are right-angled triangles.
[0008] Preferably, the strap is slidably connected within the first groove.
[0009] Preferably, the radius of the second groove is the same as the radius of the limiting block, the radius of the limiting block is larger than the radius of the connecting rod, and the connecting rod passes through the surface of the fixing plate and is fixedly connected to the limiting block.
[0010] Preferably, the two ends of the second spring are fixedly connected to the surface of the fixed plate and the surface of the anti-slip pad, respectively, and the inner surface of the second spring does not contact the outer surface of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This five-needle pine grafting fixing device is equipped with a clamping strap and a locking structure. After the rootstock and branches for grafting are cut and processed, they are wrapped with plastic film and placed in the placement groove. One end of the binding strap is inserted into the fixing block and exits through the sliding groove on the other side. Under the action of spring 1, one side of the rotating plate is pushed, so that the locking block 2 on the other side of the rotating plate abuts against the surface of the binding strap. When the binding strap is pulled, the inclined surface of the locking block 1 contacts the inclined surface of the locking block 2, pushing the locking block 2 outward, so that spring 1 is compressed. After the inclined surfaces separate, spring 1 continues to make the locking block 2 abut against the surface of the binding strap, thereby tightening the two sets of clamping straps. The right-angled edges of the locking block 2 and the locking block 1 interlock with each other, thereby preventing the clamping straps from loosening. When not in use, the rotating plate is pressed down, so that the locking block 2 and the locking block 1 no longer contact each other, thereby separating the clamping strap and the locking structure. The clamping strap and locking structure facilitate the fixing of the rootstock and scion. At the same time, it can be disassembled and reused when not in use.
[0014] 2. This five-needle pine grafting fixing device is equipped with an auxiliary structure. The rootstock and scion are placed in the placement groove. The placement groove prevents the rootstock and scion from sliding. At the same time, the spring and the anti-slip pad layer work together to press the rootstock and scion against the surface of the anti-slip pad layer when the clamping strap and locking structure are tightened, which further increases the stability during grafting and reduces the possibility of the rootstock and scion separating during grafting.

[0021] 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.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] A five-needle pine grafting fixing component includes a fixing plate 1. Rotary shaft seats 11 are fixedly connected to both sides of the fixing plate 1. A rotating shaft 12 is fixedly connected to the surface of the rotating shaft seat 11. Two sets of clamping straps 2 are rotatably connected to the surface of the rotating shaft 12. A strap 21 is fixedly connected to the surface of one set of clamping straps 2. Multiple sets of locking blocks 22 are fixedly connected to the surface of the strap 21. A locking structure 3 is provided on the surface of the other set of clamping straps 2. The locking structure 3 includes a fixing block 31. A groove 32 is formed on the surface of the fixing block 31. A rotating shaft 33 is fixedly connected to the inner wall of the groove 32. A rotating plate 34 is rotatably connected to the outer side of the rotating shaft 33. Locking blocks 2 are fixedly connected to the surface of the rotating plate 34. 35. A spring 36 is fixedly connected to the surface of the rotating plate 34. A locking groove 37 is provided on the inner side of the groove 32. Sliding grooves 38 are provided on both sides of the fixing block 31. An auxiliary structure 4 is provided on the surface of the fixing plate 1. The auxiliary structure 4 includes a second sliding groove 41. A limiting block 42 is slidably connected inside the second sliding groove 41. A connecting rod 43 is fixedly connected to the surface of the limiting block 42. A spring 44 is sleeved on the outer side of the connecting rod 43. An anti-slip pad 45 is fixedly connected to the surface of the connecting rod 43. A placement groove 46 is provided on the surface of the anti-slip pad 45. A clamping strap 2 and a locking structure 3 are provided. After the rootstock and branches for grafting are cut and processed, they are wrapped with plastic film. After winding, place it in the placement slot 46. Insert one end of the strap 21 into the fixing block 31 and out through the sliding groove 38 on the other side. Under the action of the spring 36, push one side of the rotating plate 34, so that the locking block 35 on the other side of the rotating plate 34 abuts against the surface of the strap 21. When the strap 21 is pulled, the inclined surface of the locking block 22 contacts the inclined surface of the locking block 35, pushing the locking block 35 outward, so that the spring 36 is compressed. After the inclined surfaces separate, the spring 36 continues to make the locking block 35 abut against the surface of the strap 21, thereby tightening the two sets of clamping straps 2. The locking block 35 and the right angle side of the locking block 22 interlock, thereby preventing the clamping straps 2 from loosening. When in use, press the rotating plate 34 to separate the second clamping block 35 from the first clamping block 22, thereby separating the clamping strap 2 and the locking structure 3. The clamping strap 2 and the locking structure 3 facilitate the fixation of the rootstock and scion. They can be disassembled and reused when not in use. An auxiliary structure 4 is provided to place the rootstock and scion in the placement groove 46. The placement groove 46 prevents the rootstock and scion from sliding. At the same time, the second spring 44 and the anti-slip pad 45 work together to press the rootstock and scion against the surface of the anti-slip pad 45 when the clamping strap 2 and the locking structure 3 are tightened, further increasing the stability during grafting and reducing the possibility of separation between the rootstock and scion during grafting.
[0024] Furthermore, the two ends of the spring 36 are fixedly connected to the inner wall surface of the groove 32 and the surface of the rotating plate 34, respectively. The rotating plate 34 is a rotatable structure on the rotating shaft 33. Under the action of the spring 36, one side of the rotating plate 34 is pushed, so that the locking block 35 on the other side of the rotating plate 34 abuts against the surface of the strap 21.
[0025] Furthermore, both the first clamp 22 and the second clamp 35 have right-angled triangular cross sections. When the strap 21 is pulled, the inclined surface of the first clamp 22 contacts the inclined surface of the second clamp 35, pushing the second clamp 35 outward and compressing the first spring 36. After the inclined surfaces separate, the first spring 36 continues to press the second clamp 35 against the surface of the strap 21, thereby tightening the two sets of clamping straps 2. The clamping straps 2 are prevented from loosening by interlocking the right-angled sides of the second clamp 35 and the first clamp 22.
[0026] Furthermore, the strap 21 is slidably connected in the groove 38, and one end of the strap 21 can be inserted into the fixing block 31 and exit through the groove 38 on the other side.
[0027] Furthermore, the radius of the second slide groove 41 is the same as the radius of the limiting block 42. The radius of the limiting block 42 is larger than the radius of the connecting rod 43. The connecting rod 43 passes through the surface of the fixing plate 1 and is fixedly connected to the limiting block 42. The second slide groove 41 cooperates with the limiting block 42 to prevent the connecting rod 43 from falling out of the second slide groove 41 and to limit the connecting rod 43.
[0028] Furthermore, the two ends of the second spring 44 are fixedly connected to the surface of the fixed plate 1 and the surface of the anti-slip pad 45, respectively. The inner surface of the second spring 44 does not contact the outer surface of the connecting rod 43, and the second spring 44 will not interfere with the connecting rod 43 when it deforms.
[0029] Furthermore, the anti-slip pad 45 is made of rubber. Through the cooperation of spring 2 44 and anti-slip pad 45, the rootstock and scion are pressed against the surface of the anti-slip pad 45 when the clamping strap 2 and the locking structure 3 are tightened.
[0030] Working principle: After the rootstock and scion are cut and processed, they are wrapped with plastic film and placed in the placement groove 46. The placement groove 46 prevents the rootstock and scion from sliding. One end of the grafting strap 21 is inserted into the fixing block 31 and exits through the sliding groove 38 on the other side. Under the action of the spring 36, one side of the rotating plate 34 is pushed, causing the locking block 35 on the other side of the rotating plate 34 to abut against the surface of the grafting strap 21. When the grafting strap 21 is pulled, the inclined surface of the locking block 22 contacts the inclined surface of the locking block 35, pushing the locking block 35 outward, causing the spring to... When spring 36 is compressed and the inclined planes separate, spring 36 continues to press the second clamping block 35 against the surface of the strap 21, thereby tightening the two sets of clamping straps 2. The right-angled edges of the second clamping block 35 and the first clamping block 22 engage with each other, thereby preventing the clamping straps 2 from loosening. With the cooperation of spring 44 and anti-slip pad 45, when the clamping straps 2 and the engaging structure 3 are tightened, the rootstock and scion are pressed against the surface of the anti-slip pad 45. When not in use, press the rotating plate 34 so that the second clamping block 35 and the first clamping block 22 no longer contact each other, thereby separating the clamping straps 2 and the engaging structure 3.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
