Description

Technical Field

[0001] This utility model relates to the field of grafting technology, and in particular to a labor-saving grafting and cutting device. Background Technology

[0002] Grafting is a method of asexual reproduction in plants, where a branch or bud of one plant is grafted onto the stem or root of another, allowing the two parts to grow into a single, complete plant. Grafting methods include branch grafting and bud grafting. During grafting, the cambium layers of the scion and rootstock must be in close contact to ensure the scion's survival. The branch or bud grafted onto is called the scion, and the plant being grafted onto is called the rootstock. Grafting can preserve the superior traits of the scion variety while utilizing the beneficial characteristics of the rootstock, achieving earlier fruiting, enhanced cold resistance, drought resistance, and resistance to pests and diseases. It also allows for economical use of propagation material and increases the number of seedlings. It is commonly used for the propagation of fruit trees, forest trees, and flowers, as well as for the cultivation of cucurbit and vegetable seedlings.

[0003] Grafting is an extremely important and widely used technique in agricultural production and horticultural cultivation. Typically, a tree stump about the thickness of an arm is chosen as the rootstock for grafting. The specific procedure involves carefully cutting a suitable opening in the upper part of the stump with a blade, then taking a suitable grafting branch from another plant and precisely inserting it into the cut opening to complete the grafting process. However, this seemingly simple operation actually presents many challenges. When cutting the stump with a blade, the stump itself has a certain degree of hardness and toughness, requiring the operator to press down on the blade and apply considerable force to make a smooth cut. This step is often particularly challenging for female workers, as women generally have less strength than men and find it difficult to withstand such high-intensity force. Even more serious is the fact that when multiple stumps need to be grafted sequentially, the continuous force of cutting puts enormous pressure and friction on the hands. Over time, this not only causes extreme fatigue and soreness in the hands but can also cause substantial damage, such as blisters and muscle strain. Furthermore, after successfully making an incision, if the blade is removed from the stump, the incision will quickly close due to the stump's elasticity. This makes it difficult to insert the grafting branch, forcing the operator to laboriously pry the incision open again. The entire grafting process becomes extremely cumbersome and inconvenient, significantly reducing the efficiency and quality of the grafting work.

[0004] Therefore, those skilled in the art have provided a labor-saving grafting and cutting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a labor-saving grafting and cutting device that is simple to operate, convenient to use, and more labor-saving.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a labor-saving grafting and cutting device, comprising two clamping plates, an extension rod fixedly provided at the rear end of each of the two clamping plates, and a second electric telescopic rod fixedly provided between the two extension rods;

[0007] One of the two extension rods is fixedly provided with an electric telescopic rod at its upper end. A square rod is rotatably provided at the upper end of the electric telescopic rod. A square slider is movably sleeved on the body of the square rod. A thick blade is fixedly provided at the lower end of the square slider.

[0008] Furthermore, a trapezoidal groove is provided on the upper end of one side of the thick blade, and a trapezoidal slider is slidably disposed inside the trapezoidal groove.

[0009] Furthermore, a thin blade is fixedly provided at one end of the trapezoidal slider, and the thin blade is longer than the thick blade.

[0010] Furthermore, a baffle is rotatably provided on the upper end of the thick blade near the side of the thin blade.

[0011] Furthermore, both the No. 1 and No. 2 electric telescopic poles are equipped with external batteries and controllers, and the batteries are rechargeable batteries.

[0012] This utility model has the following beneficial effects:

[0013] This invention presents a labor-saving grafting and cutting device. An electric telescopic rod drives a clamping plate to automatically clamp the tree stump and pushes the blade for cutting, completely solving the problem of the laborious manual pressing of the blade in traditional operations. It provides significant convenience, especially for female workers. The device employs a double-blade design: a thin blade for precise slit opening and a thick blade to enlarge the incision and support the stump to prevent the incision from closing due to elastic rebound. This avoids the tedious steps of repeatedly opening the incision in traditional operations, significantly improving grafting efficiency. The rotating connection between the square rod and the electric telescopic rod, along with the free-sliding design of the square slider, allows for flexible adjustment of the blade angle and position according to different rootstocks, enhancing the device's applicability. The entire process, from clamping and cutting to grafting, is integrated, making operation simple and convenient, eliminating the need for frequent tool changes and greatly reducing operational complexity. Furthermore, the device is equipped with a rechargeable battery and controller for easy mobile use in the field, enhancing its practicality. This device systematically solves the three major pain points of traditional grafting: laborious operation, incision rebound, and tedious operation, especially improving the operational feasibility for female workers, and has significant practical value and promotional significance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 An embodiment of this utility model provides a labor-saving grafting and cutting device, comprising two clamping plates 8, each with an extension rod 9 fixedly mounted at its rear end, a second electric telescopic rod 7 fixedly mounted between the two extension rods 9, a first electric telescopic rod 1 fixedly mounted at the upper end of one of the two extension rods 9, a square rod 2 rotatably mounted at the upper end of the first electric telescopic rod 1, a square slider 3 movably mounted on the body of the square rod 2, a thick blade 6 fixedly mounted at the lower end of the square slider 3, a trapezoidal groove 11 opened on the upper end of one side of the thick blade 6, a trapezoidal slider 10 slidably mounted inside the trapezoidal groove 11, a thin blade 5 fixedly mounted at one end of the trapezoidal slider 10, and a baffle 4 rotatably mounted on the side of the thick blade 6 near the thin blade 5.

[0022] Both the No. 1 electric telescopic pole 1 and the No. 2 electric telescopic pole 7 are equipped with external batteries and controllers, and the batteries are rechargeable batteries.

[0023] Specifically, the clamping plate 8 automatically clamps the tree stump via the second electric telescopic rod 7, replacing manual fixation, and then the blade is pushed down to cut via the first electric telescopic rod 1. The entire process is powered by an electric mechanism, significantly reducing operational intensity and especially addressing the weakness of female workers. The thin blade 5 is used for precise slit opening, while the thick blade 6 is used to enlarge the incision. One side of the thick blade 6 is flat, and the other side has an angled cutting edge. After completion, the thin blade 5 is pulled out and slides away along the trapezoidal groove 11, leaving the thick blade 6 within the incision for support, completely avoiding the problem of the incision closing due to the elastic rebound of the tree stump in traditional operations. The baffle 4 can rotate to lock the position of the thin blade 5, ensuring cutting stability. The square rod 2 is rotatably connected to the first electric telescopic rod 1, and the square slider 3 can slide freely along the square rod 2. Users can adjust the blade angle and horizontal position arbitrarily to adapt to rootstocks of different thicknesses and shapes, expanding its applicability.

[0024] Working principle: In use, first place the tree stump to be grafted between the two clamping plates 8. Then activate the second electric telescopic rod 7, which shortens, bringing the two clamping plates 8 closer together and tightly clamping them onto the tree stump. During this process, since the square rod 2 and the first electric telescopic rod 1 are rotatable, the angle of the rods can be adjusted, thereby adjusting the angles of the thick blade 6 and the thin blade 5. Combined with the square slider 3 sliding on the square rod 2, the thick blade 6 and the thin blade 5 are positioned appropriately on the upper part of the grafted tree stump. Then activate the first electric telescopic rod 1. The shortening of rod 1 causes the thick blade 6 and thin blade 5 to move downwards, allowing for the cutting of the grafting stump. After cutting, the baffle 4 is rotated 90° to disengage from the thin blade 5, allowing the thin blade 5 to be pulled upwards. Simultaneously, the trapezoidal slider 10 disengages from the trapezoidal groove 11. At this point, even if the thin blade 5 is pulled out, the thick blade 6 will block the opening cut into the grafting stump, preventing it from closing. The corresponding grafting branch can then be inserted into the opening without needing to pry it open again. After grafting, the thick blade 6 can be removed from the grafting stump for other operations. The entire process is labor-saving, simple to operate, and convenient to use.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
