Description

Technical Field

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

[0002] Vegetable grafting is a common agricultural technique that combines two different vegetable plants through grafting technology to form a new vegetable plant. This technology can improve the yield and quality of vegetables, and at the same time increase the disease resistance and adaptability of vegetables. Grafting clips are usually required for fixation during vegetable grafting.

[0003] Publication No. CN215530125U describes a quick-fix fixture for vegetable grafting that can control the tightening force according to different crops and thicknesses. After use, the outer arc-shaped member is pushed to separate it from the inner arc-shaped member, and the first and second arc-shaped fixing members are automatically unlocked. This allows for the fixture to be recycled, is very environmentally friendly, and saves costs. However, the existing technology still has drawbacks:

[0004] 1. In the prior art, the inner arc-shaped part and the outer arc-shaped part are locked and connected by a locking assembly. After the inner arc-shaped part and the outer arc-shaped part are locked, both ends are provided with sockets that match the plug-in part. The plug-in part and the socket are locked and connected by a self-locking assembly. The tightening force can be controlled according to different crops and different thicknesses. However, due to the irreversibility of the external and internal teeth when connected in the prior art, they can only be reduced toward the inner circle and cannot be expanded and adjusted toward the outside. Therefore, once the plant is fixed, no growth space is provided for the plant. As the plant grows, the branches and trunks continue to thicken. The plant will be deformed under the pressure of the clamp, which is not conducive to the growth of the plant.

[0005] 2. After use, the prior art pushes the outer arc-shaped part to separate it from the inner arc-shaped part, and the first arc-shaped fixing part and the second arc-shaped fixing part are automatically unlocked, which has realized the recycling of the clamp, is very environmentally friendly and saves costs. However, the prior art uses a large number of inner and outer teeth to engage with each other, which has a large friction force and is not convenient for disassembly. Moreover, as the branches of the plant grow, the arc-shaped fixing frame will be squeezed, increasing the friction force and greatly increasing the difficulty of unlocking. Utility Model Content

[0006] The technical problem to be solved by the utility model is to solve the above problems and provide a grafting clip.

[0007] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, wherein the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame.

[0008] As an improvement, the locking mechanism includes a fixed block fixedly connected to the middle of the upper part of the second fixed plate, a fixed rod is inserted in the middle of the fixed block, the fixed rod passes through the first fixed plate and the second fixed plate, support plates are rotatably connected on both sides of the fixed block, a support frame is rotatably connected between the upper parts of the support plates, the lower end of the support frame is rotatably connected to the upper end of the fixed rod, and a handle is fixedly connected to the front end of the support frame.

[0009] As an improvement, the clamping mechanism includes movable bins opened at the lower ends of both sides inside the fixed rod, and the movable bins are fixedly connected to one end of a spring close to each other on one side, and the other end of the spring is fixedly connected to one side of a clamping plate, and the other side of the clamping plate is fixedly connected to a hemispherical clamping block, and a matching clamping groove is opened at the corresponding clamping block inside the fixed plate.

[0011] As an improvement, the buffer mechanism includes several springs 2 evenly distributed on the upper part of splint 1 and the lower part of splint 2. The springs 2 are fixedly connected to a semicircular air-permeable plate at one end away from splint 1 and splint 2, and the upper and lower air-permeable plates are symmetrically connected to each other.

[0012] The advantages of the present invention compared with the prior art are: 1. The present invention sets a fixing frame 1 and a fixing frame 2 which are docked and used in conjunction with each other. A splint 1 is set at the upper end of the fixing frame 1, and the lower end of the fixing frame 2 is connected to the splint 2 through an adjustment mechanism. By turning the knob, the distance and clamping force between the splint 1 and the splint 2 can be controlled according to the thickness of the material stem. At the same time, a buffer mechanism is set at the upper end of the splint 1 and the lower end of the splint 2 to connect the air permeable plate. A certain buffer space is created between the splint and the air permeable plate through the spring 2, which facilitates the subsequent growth of the vegetable stems and prevents deformation of the grafting position due to excessive pressure.

A fixing plate 1 and a fixing plate 2 are respectively provided on the other side of the fixing frame 1 and the fixing frame 2. A locking mechanism is provided at the upper end of the fixing plate 2. By pressing down the handle, the fixing rod moves downward and passes through the fixing plate 1 and the fixing plate 2. At the same time, a clamping mechanism is provided at the lower end of the fixing rod to fix the equipment by clamping the clamping block in the clamping slot in the fixing plate 1. When dismantling, it is only necessary to lift the handle and pull the fixing rod to disengage the clamping block from the clamping slot to complete the unlocking. Compared with the existing technology, installation and disassembly are more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

A matching card slot 7.5 is provided inside the fixed plate 3 corresponding to the card block 7.4. By pressing the handle 6.5, the lower end of the support frame 6.4 drives the fixed rod 6.2 to move downward so that it passes through the fixed plate 1 3 and the fixed plate 2 5. When the card block 7.4 moves to the card slot 7.5, it is pushed by the spring 1 7.2 to pop out of the movable bin 7.1 so that the card block 7.4 is clamped in the card slot 7.5, thereby locking the fixed frame 1 and the fixed frame 2 4. When opening, lift the handle 6.5 to drive the fixed rod 6.2 to rise so that the card block 7.4 pops out of the card slot 7.5 to open the clamp.
