Description

Technical Field

[0001] The utility model relates to the technical field of grafting tools, in particular to a grafting tool used in forest grafting technology. Background Art

[0002] Grafting is a method of artificial plant propagation where a branch or bud of one plant is attached to the stem or root of another, allowing the two parts to grow into a complete plant. When grafting trees, tools are used to cut the trees.

[0003] Chinese patent CN203435411U discloses a grafting tool comprising a shank, a handle connected to one end of the shank, and a blade disposed on the bottom surface of the shank; a side surface of the shank is provided with an arc-shaped concave surface, and the tip of the blade is oriented obliquely downward. Because the side surface of the shank is provided with an arc-shaped concave surface and the tip of the blade is oriented obliquely downward, when excavating a slot away from the end of a ladder, as long as the arm applies force relatively vertically downward, the incision will naturally be inclined inward. Applying force vertically downward is easier to operate than applying force obliquely inward, saving effort and eliminating the need to frequently climb up and down a ladder. While ensuring the quality of the incision, the labor intensity is low, the production efficiency is high, and the use effect is more ideal.

[0004] Different people have different habits when operating grafting tools, and need to adjust the tools to make their own use more convenient and comfortable. However, the length of the above-mentioned patent is fixed and cannot be adjusted during use, which is difficult to meet different usage needs. In addition, the above-mentioned patent cannot protect the blade, which is easy to accidentally hurt people during the process of moving and carrying. Therefore, in view of the above situation, it is urgent to develop a grafting tool for forest grafting technology with an adjustable overall length, which is convenient for adjustment according to the usage habits of different people; the blade protection is convenient, and the blade is prevented from accidentally hurting people during the process of moving and carrying, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of the utility model is to provide a grafting tool for forest grafting technology to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The tool holder is fixed with a plurality of holes for passing the limit pins, and the top of the tool holder is fixed with a clamping mechanism, and the clamping mechanism has ...

[0008] Preferably, the operating handle is made of wood.

[0009] Preferably, the distance between any two adjacent jacks is 1 cm.

[0010] Preferably, the protective sleeve is made of plastic.

[0011] Preferably, the inner width of the protective sleeve is 1-2 mm smaller than the thickness of the tool body.

[0012] Preferably, the clamping mechanism comprises a card housing and a clamping bolt, wherein the card housing is fixed to the top of the mounting shell, and the clamping bolt is installed on the card housing.

[0013] The beneficial effects of the present invention are as follows: when using the grafting tool used in the forest grafting technology, the protective cover is placed in the housing and clamped, and the person holds the operating handle to operate the tool body. In addition, the push-pull rod is pulled to remove the limit pin from the socket, and then the tool body is moved back and forth to adjust the overall length to adapt to the usage habits of different people. After adjustment, the limit pin is inserted into the socket to fix the tool body; when moving and carrying, the protective cover is taken out of the housing, and then the protective cover is clamped on the tool body to cover the blade, thereby preventing the blade from accidentally injuring people during the movement and carrying process. In summary, the overall length of the present invention is adjustable, which is convenient for adjustment according to the usage habits of different people; it is convenient to protect the blade, and prevent the blade from accidentally injuring people during the movement and carrying process.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figures 1 to 5In an embodiment of the present invention, a grafting tool for forest grafting technology includes a mounting shell 1, an operating handle 2, a screw 3, a tool body 4, a limiting mechanism 5, a clamping mechanism 6 and a protective cover 7. The mounting shell 1 is slidably mounted with a tool body 4 extending to the outside thereof. The front end of the tool body 4 is provided with a blade 401. The operating handle 2 is detachably fixed to the rear end of the mounting shell 1 by a screw 3. The operating handle 2 is made of wood. The mounting shell 1 is mounted with a limiting mechanism 5 that passes through the tool body 4. The limiting mechanism 5 includes: a push-pull rod 501, a limiting latch 502 and a spring 503. The push-pull rod 501 is located on the outside of the mounting shell 1. Two limiting latches that pass through the mounting shell 1 and the tool body 4 are fixed on the push-pull rod 501. 502, there are two springs 503, each spring 503 is located on the outside of a limit pin 502, one end of the spring 503 is fixed to the push-pull rod 501 and the other end is fixed to the mounting shell 1, and the tool body 4 is provided with a plurality of sockets 402 for the limit pin 502 to pass through. The distance between any two adjacent sockets 402 on the left and right is 1 cm. A clamping mechanism 6 is fixed on the top of the mounting shell 1, and a protective sleeve 7 is clamped in the clamping mechanism 6. The protective sleeve 7 is used to cover the blade 401.
