Description

A foldable seedling grafting fixing device Technical Field

[0001] This utility model relates to the field of seedling grafting technology, and in particular to a foldable seedling grafting fixing device. Background Technology

[0002] Grafting propagation involves transplanting a part of a plant's vegetative organs onto another plant. The branch used for grafting is called the scion, the bud used is called the grafting bud, the plant being grafted is called the rootstock, and the seedling that survives the graft is called a grafted seedling. A seedling grafting fixing device is a special tool or device used to fix the scion and rootstock during the grafting process, ensuring that the two are in close contact to promote healing. Its core function is to provide stable physical support, prevent displacement or loosening, and protect the cut from external environmental influences.

[0003] To address this, patent publication CN219182160U discloses a seedling grafting and fixing device, comprising an upper fixing component, a lower fixing component, and an adjusting rod assembly. The lower fixing component is rotatably connected to the lower end of the adjusting rod assembly, and the upper fixing component is rotatably connected to the upper end of the adjusting rod assembly. The upper fixing component includes an upper support frame, with four upper fixing claws threaded through the surface of the upper support frame. The lower fixing component includes a lower support frame, with four lower fixing claws threaded through the surface of the lower support frame. By setting the adjusting rod assembly, the upper and lower fixing components can be relatively fixed. By setting the four upper and lower fixing claws arranged in a circular array, the root and grafting part of the seedling can be clamped and fixed. Furthermore, the clamping plates distributed around the seedling not only effectively prevent the seedling from shaking, but also have a high degree of fit between the clamping plates and the seedling, thereby greatly improving the fixing effect of the seedling.

[0004] The aforementioned seedling grafting and fixing device can clamp and fix the seedling roots and grafting parts, and the clamping plates are distributed around the seedling. This not only effectively prevents the seedling from shaking, but also ensures a high degree of fit between the clamping plates and the seedling, thereby greatly improving the fixing effect. However, when the device is taken out of the house, it occupies a large volume, is not portable enough, and is difficult to take out. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable seedling grafting and fixing device to solve the problem that existing seedling grafting and fixing devices are difficult to carry.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a foldable seedling grafting and fixing device, including a second support rod;

[0007] The top of the second support rod is equipped with a folding structure, and the folding structure includes a fixing plate installed on one side of the first support rod, and a rotating shaft installed on the inner side of the fixing plate;

[0008] The top of the folding structure is equipped with a first support rod, the top of the first support rod is equipped with an mounting plate, and the inner side of the mounting plate is equipped with a second fixing ring, and the top of the second fixing ring is equipped with a telescopic structure.

[0009] The telescopic structure is equipped with a first fixing ring at its top end, and a connecting plate is installed on the outer side of the first fixing ring and the second fixing ring. A threaded rod passes through the middle of the connecting plate, and a nut is installed on the outer side of the threaded rod.

[0010] In use, firstly, the first and second fixing rings are fixed to different seedlings. The fixing rings are divided into four parts. The gap between the fixing rings can be adjusted by turning the nuts, so that the fixing rings can fix different seedlings. After the first and second fixing rings are fixed, the positioning plate at the bottom is pressed into the ground. Turning the rotating block will drive the screw to rotate. The rotation of the screw will drive the tip to rotate. The tip will insert into the soil. When the tip and the screw are inserted into the soil, the device can be fixed.

[0011] Furthermore, a mounting screw is installed at one end of the rotating shaft, and the mounting screw and the fixing plate form a threaded connection. The mounting screw is arranged in a ring and can fix the rotating shaft.

[0012] Furthermore, a positioning structure is installed at the bottom end of the second support rod. The positioning structure includes a positioning plate installed at the bottom end of the second support rod, a screw rod passing through the middle of the positioning plate, a rotating block installed at the top end of the screw rod, and a pointed tip at the bottom end of the screw rod. The positioning structure makes the device installation more stable.

[0013] Furthermore, the outer side wall of the screw is uniformly provided with external threads, and the inner side wall of the positioning plate is uniformly provided with internal threads that cooperate with the external threads. The screw and the positioning plate are threadedly connected, and the rotation of the screw can drive the tip to rise and fall.

[0014] Furthermore, the nuts and threaded rods form a threaded connection, and the nuts are arranged at equal intervals. Tightening the nuts can adjust the gap between the retaining rings.

[0015] Furthermore, the telescopic structure includes a first telescopic rod installed at the bottom end of a first fixed ring, and a fixing screw installed on one side of the first telescopic rod. A second telescopic rod is installed at the bottom end of the first telescopic rod. The telescopic structure can adjust the gap between the first fixed ring and the second fixed ring.

[0016] Furthermore, the second telescopic rod has a sliding groove inside, and the bottom end of the first telescopic rod has a slider. The second telescopic rod and the first telescopic rod form a sliding structure, and the first telescopic rod can slide inside the second telescopic rod.

[0017] The advantages of the foldable seedling grafting fixing device provided by this utility model are as follows: when in use, the folding structure allows the support rod to be covered, and the device is easy to carry after being covered; the telescopic structure can adjust the distance between the first fixing ring and the second fixing ring, allowing the device to adapt to different situations; and the positioning structure makes the device more stable.

[0018] A fixing plate is installed at the bottom of the first support rod. The rotating shaft inside the fixing plate can rotate, which will drive the second support rod to rotate. The second support rod can be folded along the rotating shaft. When the second support rod needs to be fixed, the mounting screws can be tightened to fix the rotating shaft. When the second support rod needs to be covered, the mounting screws can be unscrewed to cover the second support rod. After the support rod is covered, the device can be easily taken out, thus achieving the purpose of making the seedling grafting fixing device easy to carry.

[0019] A second telescopic rod is installed at the top of the second fixing ring. The second telescopic rod and the first telescopic rod form a sliding structure. The first telescopic rod can slide inside the second telescopic rod. The sliding of the first telescopic rod can adjust the height of the top first fixing ring, so that the gap between the first fixing ring and the second fixing ring can be adjusted. This allows the device to adapt to different situations. When it is necessary to fix the first telescopic rod, the fixing screw can be tightened to fix the first telescopic rod. This achieves the purpose of making it easy to adjust the gap between the fixing rings in the seedling grafting fixing device. Attached Figure Description
