Description

Technical Field

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

[0002] Fruit trees are a general term for perennial plants and their rootstocks that can produce edible fruits and seeds. Grafting of fruit trees can be divided into the following three types depending on the grafting location, rootstock age, and number of grafts: (1) Trunk grafting: Grafting is performed on the trunk. This is often used in densely planted orchards with younger trees. The trunk is cut off 50 to 60 cm from the ground, and two to three scions are grafted using the bark grafting or cleft grafting method. After the branches survive, a strong new shoot is selected as the new trunk to maintain its growth advantage. (2) Main branch grafting: The main branch is cut off at 20 to 40 cm, and two scions are grafted using the subcortical grafting or cleft grafting method. The crown can be restored in 1 to 2 years. This is suitable for densely planted orchards with older trees. (3) Multi-branch grafting: The original tree structure is maintained, and multiple scions are grafted on the main trunk branches. This not only quickly restores the crown, but also restores yield early.

[0003] However, during the high grafting and crown replacement process of fruit trees, the grafting site takes a long time to heal completely. Before it is completely healed, the wind resistance of the grafting site is very poor, especially when encountering typhoon weather, the scion can easily break off from the grafting site, causing grafting failure. Therefore, this application document provides a grafting clamp for fruit tree grafting. Summary of the Invention

[0006] Furthermore, a first handle is fixedly mounted on the connecting plate.

[0007] Furthermore, a second handle is fixedly mounted on the arc-shaped plate.

[0008] Furthermore, the locking mechanism includes a locking hole constructed at the other end of the connecting plate and the arc-shaped plate, and a latch is inserted into the locking hole.

[0009] Furthermore, the clamping mechanism includes a threaded rod threadedly connected to the connecting plate and the middle part of the arc plate, the end of the threaded rod is rotatably connected to the clamping plate, a spring is fixed to the middle part of the outside of the clamping plate, the spring is sleeved on the outside of the threaded rod and the other end is fixed to the middle part of the connecting plate and the inside of the arc plate.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0018] The present application provides a grafting clamp for fruit tree grafting, which is mainly used to solve the problem that the wind resistance of the grafting site is very poor before it is completely healed, especially in typhoon weather, the scion is very easy to break off from the grafting site, causing grafting failure, and provides the following technical solutions, which will be described in detail below: Example 1:

[0019] like Figure 1 、 Figure 2 、 Figure 3As shown, in some embodiments, it includes a connecting plate 1, the end of the connecting plate 1 is hinged with an arc-shaped plate 2, the other end of the connecting plate 1 and the arc-shaped plate 2 is provided with a locking mechanism 3 for locking, and a clamping mechanism 4 for clamping and fixing is provided between the connecting plate 1 and the arc-shaped plate 2; the locking mechanism 3 includes a locking hole 301 constructed at the other end of the connecting plate 1 and the arc-shaped plate 2, and a pin 302 is inserted into the locking hole 301; the clamping mechanism 4 includes a threaded rod 401 threadedly connected to the middle part of the connecting plate 1 and the arc-shaped plate 2, the end of the threaded rod 401 is rotatably connected to the clamping plate 402, and a spring 403 is fixed to the middle part of the outside of the clamping plate 402, the spring 403 is sleeved on the outside of the threaded rod 401 and the other end is fixed to the middle part of the inside of the connecting plate 1 and the arc-shaped plate 2; protective pads 404 are fixed inside the two clamping plates 402.

[0020] Specifically: by providing the connecting plate 1, the curved plate 2 and the locking mechanism 3, the opening and closing angles can be adjusted, providing better versatility and flexibility; the locking mechanism 3 can ensure that the grafting clamp can be firmly locked after being adjusted to the appropriate position, preventing the scion from shifting or falling off due to loosening, thereby improving the success rate of grafting; the design of the clamping mechanism 4 allows the user to quickly and accurately fix the scion in the appropriate position, and can effectively prevent the scion from disconnecting from the grafting port even in a windy environment, simplifying the grafting process and saving time and labor.

[0021] The working principle here is: when the grafting clamp is needed for fruit tree grafting, the staff will first wrap the grafting film on the grafting port, then take out the latch 302 from the locking hole 301, open the curved plate 2, and then take it near the grafting port, cover the curved plate 2, and finally use the latch 302 to insert into the locking hole 301. At this time, the connecting plate 1 and the curved plate 2 form a closed circular ring. Here, the threaded rod 401 threadedly connected to the connecting plate 1 can be rotated first, so that the clamping plate 402 connected to the other end of the threaded rod 401 can clamp the grafting port, and then The threaded rod 401 threadedly connected to the curved plate 2 is then rotated, so that the clamping plate 402 rotatably connected to the other end of the threaded rod 401 can also clamp the grafting port, preventing the scion from shifting or falling off due to loosening, thereby improving the success rate of grafting; even in a windy environment, it can effectively prevent the scion from breaking off from the grafting port, simplifying the grafting process, saving time and labor. At the same time, the protective pad 404 fixedly installed on the curved plate 2 conforms to the natural shape of the fruit tree branches, can reduce damage to the bark, and at the same time disperse the clamping pressure to avoid crushing the scion. The spring 403 can provide a stable elastic force, making the rotation of the threaded rod 401 more stable.

This arrangement further facilitates operation and improves ease of use.
