Description

Technical Field

[0001] The utility model relates to the technical field of forestry grafting, in particular to a seedling grafting clamp. Background Art

[0002] Grafting is one of the artificial propagation methods of plants. It is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts grow into a complete plant. Grafting is carried out by using the healing function of plants after being injured. Grafting clips are needed to fix the grafts during the grafting process. Grafting clips are the most commonly used tools in plant grafting. The quality of the grafting clips directly determines whether the plant can be grafted successfully.

[0003] The prior art discloses a forestry grafting seedling clamping device with a publication number of CN212087101U, comprising a rectangular block, a first clamping block is disposed on the upper surface of the rectangular block, a lifting mechanism corresponding to the first clamping block is disposed at the bottom of the rectangular block, a connecting rod is fixedly connected to the side wall of the first clamping block, a second clamping block is fixedly connected to the end of the connecting rod away from the first clamping block, and a clamping mechanism is disposed inside the second clamping block and inside the rectangular block. The forestry grafting seedling clamping device realizes that by turning the first handle, the first clamping block can be driven to move to clamp the branches, and by turning the second handle, the grafted seedlings can be clamped. The operation is simple and convenient, and the problem of clamping the branches and grafted seedlings of different sizes is solved, and the grafted seedlings can be stably supported to meet the needs of users.

[0004] The above utility model requires the use of a first clamping block and a second clamping block to complete the clamping of the plant, but during the clamping process, the operator needs to rotate the first handle and the second handle, which increases the operating steps of the operator. After the plant grafting is completed, the grafting device needs to be removed from the root or end of the plant. The removal process is likely to damage the roots and leaves, reducing the practicality of the use of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a seedling grafting clamp, which can clamp grafted plants of different sizes, is simple to operate, and has high efficiency, thereby solving the problems in the above-mentioned background technology.

[0008] (II) Technical solution

[0009] In order to achieve the advantages of clamping grafted plants of different sizes, simple operation and high efficiency, the specific technical solutions adopted by the utility model are as follows:

[0010] A seedling grafting clamp comprises a first clamping arm and a second clamping arm, six groups of springs are fixedly installed on the opposite surfaces of the first clamping arm and the second clamping arm, one end of the two groups of springs on the same side are fixedly installed with clamping plates, a first U-shaped mounting plate is installed on one side of the first clamping arm, a second U-shaped mounting plate is installed on one side of the second clamping arm, end surfaces of the first U-shaped mounting plate and the second U-shaped mounting plate are penetrated by pins, and the side walls of the pins are sleeved with torsion springs.

[0011] Furthermore, a hollow tube is fixedly passed through one end of the first clamping arm and the second clamping arm, a U-shaped rod is slidably passed through the interior of the two groups of hollow tubes, limiting blocks are welded at both ends of the two groups of U-shaped rods, and limiting cards are installed on the side walls of the other ends of the first clamping arm and the second clamping arm.

[0012] Furthermore, rubber pads are bonded to the opposite surfaces of the six groups of clamping plates.

[0013] Furthermore, the hollow tube and the U-shaped rod are made of stainless steel.

[0014] Furthermore, the first U-shaped mounting plate is smaller in size than the second U-shaped mounting plate.

[0015] Furthermore, the material of the limit card is PE plastic.

[0016] Furthermore, dampers are installed inside the twelve groups of springs.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a seedling grafting clamp, which has the following beneficial effects:

[0019] (1) The utility model adopts a clamping plate. When the seedling grafting clamp is actually used, the two groups of U-shaped rods are pressed with fingers. The two groups of U-shaped rods respectively drive the first clamping arm and the second clamping arm to rotate around the pin. The first clamping arm and the second clamping arm respectively drive the first U-shaped mounting plate and the second U-shaped mounting plate to rotate around the pin. The first U-shaped mounting plate and the second U-shaped mounting plate squeeze the torsion spring to accumulate elastic potential energy. A group of clamping plates between the first clamping arm and the second clamping arm are aligned with the grafting port of the plant. The grafting port and both sides of the grafting port are aligned with the clamping plates. The two groups of U-shaped rods are loosened. Under the action of the torsion spring, when the three pairs of clamping plates contact the plant, the clamping plates will squeeze the spring according to the size of the plant to contract the spring, thereby clamping the plant. The size of the two grafted plants can be clamped by the provided clamping plates, and the plants can be conveniently clamped or released, thereby improving the practicality of the seedling grafting clamp.

[0020] (2) The utility model adopts a U-shaped rod and a limit card. When storing the seedling grafting clamp, the U-shaped rod can be pushed by hand, and the two ends of the U-shaped rod are contracted in the hollow tube along the hollow tube. The U-shaped rod is continued to be pushed, and the middle section of the U-shaped rod contacts the limit card. Since the contact surface is an inclined surface and the PE plastic limit card is elastic, the U-shaped rod can be clamped by continuing to push the U-shaped rod lightly, thereby hiding the U-shaped rod. When the seedling grafting clamp needs to be used, the U-shaped rod can be pulled out by manually bending the limit card. By setting the U-shaped rod and the limit card, the length of the first clamping arm and the second clamping arm is extended, which can save more effort when clamping and save more space when storing. The weight of the seedling grafting clamp is reduced, and the work intensity of the operator is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] According to an embodiment of the utility model, a seedling grafting clamp is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-5 As shown, a seedling grafting clamp according to an embodiment of the utility model comprises a first clamping arm 1 and a second clamping arm 5, six groups of springs 2 are fixedly installed on the opposite surfaces of the first clamping arm 1 and the second clamping arm 5, a clamping plate 3 is fixedly installed on one end of the two groups of springs 2 on the same side, a first U-shaped mounting plate 6 is installed on one side of the first clamping arm 1, a second U-shaped mounting plate 7 is installed on one side of the second clamping arm 5, a pin 8 passes through the end surfaces of the first U-shaped mounting plate 6 and the second U-shaped mounting plate 7, a torsion spring 10 is sleeved on the side wall of the pin 8, and the clamping plate 3 is arranged to clamp the sizes of the two grafted plants, and conveniently clamp or release the plants, thereby improving the practicality of the seedling grafting clamp.

[0032] In one embodiment, a hollow tube 11 is fixedly passed through one end of the first clamping arm 1 and the second clamping arm 5, a U-shaped rod 9 is slidably passed through the interior of the two groups of hollow tubes 11, and limiting blocks 12 are welded at both ends of the two groups of U-shaped rods 9. Limiting cards 13 are installed on the side walls of the other ends of the first clamping arm 1 and the second clamping arm 5. By setting the U-shaped rod 9 and the limiting card 13, the length of the first clamping arm 1 and the second clamping arm 5 is extended, which can save more effort when clamping and save more space when storing, thereby reducing the weight of the seedling grafting clamp.

[0033] In one embodiment, rubber pads 4 are bonded to the opposite surfaces of the six groups of clamping plates 3 to prevent the clamping plates 3 from clamping the plants.

[0034] In one embodiment, the hollow tube 11 and the U-shaped rod 9 are made of stainless steel, which can provide qualified strength and rigidity requirements and avoid rust.

[0035] In one embodiment, the first U-shaped mounting plate 6 is smaller than the second U-shaped mounting plate 7 to facilitate the installation of the pin 8 .

[0036] In one embodiment, the material of the limiting card 13 is PE plastic. PE plastic has good flexibility and can recover quickly after slight deformation, thereby clamping the U-shaped rod 9.

[0037] In one embodiment, dampers are installed inside the twelve groups of springs 2 to limit the position of the clamping plate 3.

[0038] Working principle:

[0039] When the seedling grafting clamp is actually used, the two groups of U-shaped rods 9 are pressed with fingers, and the two groups of U-shaped rods 9 respectively drive the first clamping arm 1 and the second clamping arm 5 to rotate around the pin 8, and the first clamping arm 1 and the second clamping arm 5 respectively drive the first U-shaped mounting plate 6 and the second U-shaped mounting plate 7 to rotate around the pin 8, and the first U-shaped mounting plate 6 and the second U-shaped mounting plate 7 squeeze the torsion spring 10 to accumulate elastic potential energy, and align a group of clamping plates 3 between the first clamping arm 1 and the second clamping arm 5 with the grafting port of the plant, and align the grafting port and both sides of the grafting port with the clamping plates 3, and loosen the two groups of U-shaped rods 9. Under the action of the torsion spring 10, when the three pairs of clamping plates contact the plant, the clamping plates will squeeze the springs 2 according to the size of the plant, causing the springs 2 to contract, thereby clamping the plant, and the size of the two grafted plants can be clamped by the provided clamping plates 3. The U-shaped rod 9 is convenient for clamping or releasing plants, which improves the practicality of the seedling grafting clamp. At the same time, when storing the seedling grafting clamp, the U-shaped rod 9 can be pushed by hand, and the two ends of the U-shaped rod 9 are contracted in the hollow tube 11 along the hollow tube 11, and the U-shaped rod 9 is continued to be pushed. The middle section of the U-shaped rod 9 contacts the limiting card 13. Since the contact surface is an inclined surface and the limiting card 13 of PE plastic is elastic, the U-shaped rod 9 can be clamped by continuing to push the U-shaped rod 9 to achieve hiding of the U-shaped rod 9. When the seedling grafting clamp needs to be used, the U-shaped rod 9 can be pulled out by bending the limiting card 13 by hand. By setting the U-shaped rod 9 and the limiting card 13, the length of the first clamping arm 1 and the second clamping arm 5 is extended, which can save more effort when clamping and save more space when storing, reduce the weight of the seedling grafting clamp, and reduce the work intensity of the operator.

Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
