[0002] Grafting is one of the artificial propagation methods of plants. Specifically, it is to graft the tender branches or buds of one plant onto the stem or root of another plant, so that the two plants grow into a complete plant. It is done by using the healing function of plants after being injured. Grafting methods include cleft grafting and fusion grafting. For different grafting methods, different interfaces (or slots) and joints (or tips) need to be cut on the stock and scion. At present, in order to make the stock and scion combine more closely, people will use corresponding grafting equipment to shear the stock and scion.

[0021] Reference Figure 3In this embodiment, the tool assembly 2 specifically includes a base plate 201, two fixed slide bars 202, a lifting knife seat 203, two second springs 204, a cutter 205 and a placement seat 206. The placement seat 206 is fixedly installed on the top of the base plate 201. The top of the placement seat 206 has a placement plate, and the placement plate is provided with an avoidance opening adapted to the cutter 205. The two fixed slide bars 202 are fixedly installed on the top of the base plate 201. The lifting knife seat 203 is slidably sleeved on the two fixed slide bars 202. The cutter 205 is fixedly installed on the lifting knife seat 203. In this embodiment, the cutter 205 is specifically "V"-shaped, which is suitable for cleft grafting, and can cut the rootstock into a "V" shape. shaped notch, correspondingly, a pointed head compatible with the above-mentioned V"-shaped notch can be cut on the scion. During grafting, the pointed head on the scion is inserted into the "V"-shaped notch on the rootstock, and then it can be bandaged. The two second springs 204 are respectively mounted on the two fixed slide bars 202, the top end of the second spring 204 is fixedly connected to the lifting knife seat 203, and the bottom end is fixedly connected to the bottom plate 201, and the bottom end of the push column 4 is in contact with the top of the lifting knife seat 203. It should be noted that the cutter 205 can also be other shapes, such as a sheet blade suitable for jointing, thereby forming another tool assembly. When the cutter 205 is other shapes, the avoidance opening on the placement plate corresponds to the same shape.

[0022] In this embodiment, in order to facilitate the disassembly of the tool assembly 2, a mounting groove 101 is provided on the top of the base 1, and the bottom plate 201 is located in the mounting groove 101. A baffle 13 is fixedly installed on the top of the base 1, and the bottom of the baffle 13 contacts the bottom of the bottom plate 201. A slot is provided on the bottom plate 201. A rotating bar 11 is rotatably installed on the top of the base 1, and an insert block 12 is fixedly installed on the bottom of the rotating bar 11. The insert block 12 is located in the slot. Under the restriction of the baffle 13 and the insert block 12, the tool assembly 2 can be prevented from moving, and a handle is fixedly installed on the top of the rotating bar 11.

[0023] In this embodiment, in order to facilitate taking out the tool assembly 2 , hand levers are fixedly installed on the outer walls of both sides of the placement seat 206 .

[0024] The working principle of the softwood seedling grafting device provided by the utility model is as follows:

[0025] When in use, first place the rootstock for grafting on the top of the placement seat 206, then start the operation of the motor 9, the motor 9 drives the cam 10 to rotate, and the protruding part of the cam 10 rotates downward, it will resist the push column 4 to slide downward, and the push column 4 pushes the lifting knife seat 203 to slide downward, and the lifting knife seat 203 drives the cutter 205 to move downward, so as to cut the rootstock, and a "V" shaped opening will be left on the main body of the rootstock. During the downward movement of the push column 4, the sleeve strip 5 will also be driven to move accordingly, and the sleeve strip 5 pushes the two limit slide bars 6 to slide downward, and the two first springs 8 will be stretched, and during the downward movement of the lifting knife seat 203, the two The second spring 204 will be compressed, and when the protruding part of the cam 10 rotates from bottom to top, under the pull of the two first springs 8, the two limit slide bars 6 will automatically slide upward, so that the push column 4 will be reset upward. Similarly, under the elastic force of the two second springs 204, the lifting knife seat 203 will also slide upward, and finally the cutter 205 will be reset, and then the next stock cutting work can be prepared. The cutting method for the scion used for grafting is the same as the cutting method for the above-mentioned stock. After cutting, a pointed head will be left on the scion body, which is adapted to the "V"-shaped notch on the stock. After the pointed head is inserted into the notch, it is wrapped with a film, and the grafting work is completed;

[0026] When it is necessary to replace other tool components, first rotate the rotating bar 11 counterclockwise to disengage the insert block 12 from the slot on the bottom plate 201, then hold the two hand levers on the placement seat 206 and drag them backward to make the bottom plate 201 slide backward. As the bottom plate 201 moves, the baffle 13 will separate from the bottom plate 201, and the push column 4 will also separate from the lifting knife seat 203. After that, the tool assembly 2 can be taken away. When installing a new tool assembly 2, first place the bottom plate 201 in the installation slot 101, then press the lifting knife seat 203 downward with one hand to lower it, and push the bottom plate 201 forward with the other hand. After pushing the bottom plate 201 into place, release the lifting knife seat 203. Under the elastic force of the two second springs 204, the lifting knife seat 203 will automatically rise and contact the bottom end of the push column 4. At this time, the baffle 13 is also blocked above the bottom plate 201, and then the rotating bar 11 is rotated clockwise to insert the insert block 12 into the slot.

[0027] Compared with the related art, the softwood seedling grafting device provided by the utility model has the following beneficial effects:

[0028] The utility model provides a device for grafting tender branch seedlings. Through the arrangement of components such as a base 1, a tool assembly 2, a baffle 13, a rotating bar 11, an insert block 12, a push column 4, two limit slide bars 6, a sleeve bar 5, and two first springs 8, the tool assembly 2 is installed on the base 1 in a quickly detachable manner. When the grafting method of tender branch seedlings changes and the cutter needs to be replaced, the replacement work of the corresponding tool assembly 2 can be completed through simple operation, and the utility model has the advantages of convenient operation and time saving.
