Description

Technical Field

[0001] The utility model relates to the technical field of plant grafting, in particular to a fixing clamp for plant grafting. Background Technique

[0002] Grafting mainly utilizes the wound healing function of plants to make two grafted plants grow into a complete plant. It is divided into two forms: branch grafting and bud grafting. Since it is more difficult to pick buds, the form of branch grafting is relatively more commonly used.

[0003] For example, an agricultural grafting fixing clamp with the authorization announcement number of "CN209710788U" solves the problem that the existing agricultural grafting fixing clamp is not conducive to ventilation when binding the grafting position and is prone to rot. The above-mentioned uses two positioning clamps to clamp and position the branches of two plants, and then uses the root connection inserting rod to insert and connect, ensuring the stability of the grafting position without the need for binding. Considering the existing agricultural grafting fixing clamp, the grafting position is clamped and positioned, and the inserting rod is used for support. However, the grafting holding part is still exposed, resulting in the risk of the grafting part being infected with viruses and bacteria and reducing the grafting success rate. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing agricultural grafting fixing clamp has the risk of the grafting part being infected with viruses and bacteria and reduces the grafting success rate, and to propose a fixing clamp for plant grafting.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing clamp for plant grafting, including a rootstock and a scion. The inner wall of the rootstock abuts against the scion, the outer wall of the rootstock fits with a PE sleeve. The upper end of the PE sleeve is fixedly connected with an upper connecting ring, the lower end of the PE sleeve is fixedly connected with a lower connecting ring, and a supporting mechanism is connected to the outer wall of the scion.

[0006] Preferably, the supporting mechanism includes a first supporting semi-ring. The inner wall of the first supporting semi-ring fits with the scion. The inner wall of the first supporting semi-ring is fixedly connected with a plurality of round rods. The inner wall of the round rod abuts against a hook ring. The outer wall of the hook ring is fixedly connected with an arc-shaped plate. The outer wall of the arc-shaped plate is rotatably connected with a second supporting semi-ring.

[0007] Preferably, a clamping groove is processed on the inner wall of the second supporting semi-ring, and a splicing mechanism is connected to the inner wall of the clamping groove.

[0008] Preferably, the splicing mechanism includes a first rubber head. The outer wall of the first rubber head abuts against the clamping groove. The lower end of the first rubber head is fixedly connected with a connecting rod. The lower end of the connecting rod is fixedly connected with a second rubber head.

[0009] Preferably, the inner wall of the PE sleeve fits the scion.

[0010] Preferably, the lower end of the upper connecting ring is movably connected to the first supporting semi-ring, and the lower end of the upper connecting ring is movably connected to the second supporting semi-ring.

[0011] A fixing clamp for plant grafting proposed by the present utility model has the beneficial effect that by sleeving the PE sleeve on the joint of the scion and the rootstock, manually pressing the arc-shaped plate, the arc-shaped plate on the second supporting ring deflects at an angle until the hook ring on the arc-shaped plate hooks on different position round rods on the first supporting semi-ring. The first supporting semi-ring and the second supporting semi-ring will clamp and fix the PE sleeve and the scion, reducing the risk of virus and bacteria infection at the grafting site and improving the grafting success rate.

Detailed Embodiments

[0019] The present utility model will be further described below with reference to the drawings:

[0020] Embodiment 1:

[0021] Please refer to Figures 1-6: In this embodiment, a fixing fixture for plant grafting includes a rootstock 1 and a scion 2. The inner wall of the rootstock 1 abuts against the scion 2, the outer wall of the rootstock 1 fits with a PE sleeve 3. The upper end of the PE sleeve 3 is fixedly connected to an upper connecting ring 4, and the lower end of the PE sleeve 3 is fixedly connected to a lower connecting ring 5. A support mechanism 6 is connected to the outer wall of the scion 2.

[0022] The support mechanism 6 includes a first support semi-ring 601 which is hooked on a round rod 602 through a hook ring 603, so that the first support semi-ring 601 and the second support semi-ring 605 form cylinders of different sizes to fix and support the scion 2. The inner wall of the first support semi-ring 601 fits with the scion 2. The inner wall of the first support semi-ring 601 is fixedly connected to a plurality of round rods 602. The inner wall of the round rod 602 abuts against the hook ring 603. The outer wall of the hook ring 603 is fixedly connected to an arc plate 604. The outer wall of the arc plate 604 is rotatably connected to the second support semi-ring 605.

[0023] Put the PE sleeve 3 on the connection part of the scion 2 and the rootstock 1, manually press the arc plate 604, so that the arc plate 604 on the second support ring 605 deflects at an angle until the hook ring 603 on the arc plate 604 is hooked on different positions of the round rods 602 on the first support semi-ring 601. The first support semi-ring 601 and the second support semi-ring 605 will clamp and fix the PE sleeve 3 and the scion 2, reducing the risk of the grafting part being infected by viruses and bacteria and improving the grafting success rate.

[0024] A clamping groove 7 is machined on the inner wall of the second support semi-ring 605. A splicing mechanism 8 is connected to the inner wall of the clamping groove 7. The splicing mechanism 8 includes a first rubber head 801. Through the first rubber heads 801 at both ends of a connecting rod 802 and a second rubber head 803, the effect of splicing and fixing can be achieved at the upper and lower ends. The outer wall of the first rubber head 801 abuts against the clamping groove 7. The lower end of the first rubber head 801 is fixedly connected to the connecting rod 802. The lower end of the connecting rod 802 is fixedly connected to the second rubber head 803. The inner wall of the PE sleeve 3 fits with the scion 2. The lower end of the upper connecting ring 4 is movably connected to the first support semi-ring 601, and the lower end of the upper connecting ring 4 is movably connected to the second support semi-ring 605.

[0025] Working principle:

[0026] First, insert the scion 2 into the rootstock 1, and bend the opening of the PE sleeve 3 to make it deformed and enlarged. Then, put the PE sleeve 3 on the joint of the scion 2 and the rootstock 1, which can effectively protect the grafting part, reduce the risk of virus and bacteria infection, and improve the grafting success rate. Secondly, the grafting film can maintain the humidity of the grafting part, promote the formation and healing speed of callus, and is beneficial to the growth and survival of grafted seedlings. Move the first support semi-ring 601 and the second support ring 605 closer to the outer wall of the PE sleeve 3 until the inner walls of the first support semi-ring 601 and the second support semi-ring 605 are attached to the PE sleeve 3. Manually press the arc plate 604 to make the arc plate 604 on the second support ring 605 deflect at an angle until the hook ring 603 on the arc plate 604 hooks on the round rod 602 on the first support semi-ring 601. The first support semi-ring 601 and the second support semi-ring 605 will be clamped and fixed to the scion 2, and insert the first rubber head 801 on the connecting rod 802 into the card slot 7 inside the second support semi-ring 605. In the same way, insert the second rubber head 803 on the connecting rod 802 into the second support semi-ring 605 with a similar structure, so that the two groups of first support semi-rings 601 and second support semi-rings 605 play a role in strengthening the grafting position between the scion 2 and the rootstock 1.
