[0002] The Chinese privet (Vernicia fordii) is a deciduous tree with high economic and ecological value. This tree is not only noteworthy for its unique biological characteristics but also for the significant economic value of the oil contained in its fruit and seeds. When grafting Chinese privet plants, a grafting knife is needed to trim the plant; when the knife becomes dull, the blade needs to be replaced.

[0003] Existing replacement mechanisms typically involve drilling two holes in the cutting tool and inserting a pin to complete the tool replacement. This structure relies solely on the pin to limit the tool's position, resulting in poor overall tool stability. When the tool is cutting, it is prone to loosening under lateral force, which can also apply pressure to the side of the tool holder, causing deformation and ultimately leading to the complete loosening of the entire tool.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 4 to 7 As shown, this utility model proposes a special grafting knife for *Vernicia fordii*, including a handle 1 with a connecting groove 101, and a clamping module 2 installed inside the connecting groove 101. A cutting tool 3 is detachably mounted on the clamping module 2. When replacing the cutting tool, the clamping module 2 can clamp and fix it. The clamping module 2 includes a base 201 fixedly connected to the connecting groove 101, two support plates 202 fixedly mounted on the base 201, and a fastening plate 203. The clamping plate 204 is slidably mounted on the base 201. The clamping module 2 also includes a fastening component. The fastening component drives the clamping plate 204 to move and adjusts the distance between the fastening plate 203 and the clamping plate 204. When the distance between the fastening plate 203 and the clamping plate 204 is reduced, the fastening plate 203 and the clamping plate 204 will clamp and fix the tool. Conversely, when the tool is disassembled, the distance between the fastening plate 203 and the clamping plate 204 can be increased to facilitate the disassembly of the tool.

[0025] It should be noted that the existing connection structure for the tool 3 generally includes a groove, namely the space formed by the fastening plate 203, the clamping plate 204, and the two support plates 202. The tool 3 is installed inside this space and fixed by inserting a pin. At this time, the fastening plate 203 and the clamping plate 204 only limit the movement of the tool 3 and do not provide any fixing effect. Therefore, the tool 3 is prone to tilting to the side, causing the tool 3 to exert pressure on the support plate 202, which can easily deform and damage the support plate 202, resulting in instability of the tool 3. However, by setting up the fastening plate 203, the clamping plate 204, and the fastening components, the side of the tool 3 can be pressed and fixed, and the tool 3 is clamped and fixed within the structure of the fastening plate 203 and the clamping plate 204. Compared with fixing only by a pin, this can improve the overall integrity of the tool 3 and the tool holder 1 and prevent the tool 3 from becoming unstable.

[0026] In one embodiment, the fastening assembly includes a guide plate 211 fixedly mounted on the clamping plate 204. The guide plate 211 has an inclined surface that gradually rises from one side to the other. A connecting rod 212 is rotatably mounted in the connecting groove 101. A drive wheel 213 that fits against the inclined surface of the guide plate 211 is rotatably mounted on the connecting rod 212. A connecting block 214 is fixedly mounted on the connecting rod 212. A lever 215 is fixedly mounted on the connecting block 214. The connecting rod 212 can be driven in a labor-saving manner by rotating the lever 215. When the connecting rod 212 rotates, it drives the drive wheel 213 to rotate. The rotating drive wheel 213 will press against the inclined surface of the guide plate 211, thereby driving the clamping plate 204 to move closer to the fastening plate 203. This fixes the tool in place by the fastening plate 203 and the clamping plate 204. The lever 215 is equipped with a limiting component to position the angle of the lever 215. By limiting the lever 215, the clamping plate 204 can be prevented from loosening, thus ensuring the stability of the clamping.

[0027] The limiting component includes a positioning rod 216 that is slidably mounted on the lever 215. The handle 1 is provided with a slot 217 that engages with the positioning rod 216. By inserting the positioning rod 216 into the slot 217, the lever 215 can be limited. A rubber ring can be fitted on the drive wheel 213. The rubber ring can be slightly deformed, which makes it easier for the positioning rod 216 to connect with the adjacent slot 217.

[0028] like Figure 5 and Figure 6 As shown, in this embodiment, the cutting tool 3 is provided with multiple positioning holes 301. The clamping module 2 also includes a snap-fit ​​assembly for snapping the positioning holes 301. The snap-fit ​​assembly includes through holes provided on the fastening plate 203 and the clamping plate 204. Multiple insertion rods 206 corresponding one-to-one with the positioning holes 301 are slidably installed in the connecting groove 101. A synchronization plate 207 is fixedly installed on the multiple insertion rods 206. A guide rod 208 that is slidably connected to the tool holder 1 is fixedly installed on the synchronization plate 207. A handle 209 is fixedly installed at one end of the guide rod 208. A spring 210 is fixedly installed on the synchronization plate 207. The other end of the spring 210 is fixedly connected to the connecting groove 101. When installing the tool 3, first pull the handle 209 to drive the plug rod 206 to disengage from the fastening plate 203 and the clamping plate 204 through the transmission of the guide rod 208 and the synchronous plate 207. Then place the tool 3 inside the space formed by the fastening plate 203, the clamping plate 204 and the two support plates 202, and then release the pull on the handle 209. At this time, under the elastic force of the spring 210, the plug rod 206 enters the fastening plate 203 and enters the clamping plate 204 through the positioning hole 301, thus completing the positioning of the tool 3.

[0029] like Figures 1 to 3 andFigure 6 As shown, in this embodiment, friction plates 205 are fixedly installed on both the fastening plate 203 and the clamping plate 204. The friction plates 205 are provided with through holes for the insertion rod 206 to pass through. By setting the friction plates 205, the coefficient of friction between the tool 3 and the friction plates 205 can be increased, thereby increasing the friction force and ensuring the stability of the tool 3.

[0030] The handle 1 is fixedly equipped with a cover 102 that seals the connecting groove 101. The handle 1 is also fixedly equipped with an anti-slip handle 103, which can increase the grip and operability. The cover 102 is detachably equipped with a knife cover 104, which protects the knife 3 and prevents the knife 3 from being exposed when not in use.

[0031] In this embodiment, when installing the tool 3, firstly, pull the handle 209 to drive the plug rod 206 to disengage from the fastening plate 203 and the clamping plate 204 through the transmission of the guide rod 208 and the synchronous plate 207. Then, place the tool 3 inside the space formed by the fastening plate 203, the clamping plate 204 and the two support plates 202, and then release the pull on the handle 209. At this time, under the elastic force of the spring 210, the plug rod 206 enters the fastening plate 203 and enters the clamping plate 204 through the positioning hole 301, thus completing the positioning of the tool 3.

[0032] By rotating lever 215, the connecting rod 212 can be rotated in a labor-saving manner. The rotating connecting rod 212 will drive the drive wheel 213 to rotate. The rotating drive wheel 213 will press against the inclined surface of guide plate 211, thereby driving clamping plate 204 to move closer to fastening plate 203. This will fix the tool with fastening plate 203 and clamping plate 204. Compared with fixing only by pin, it can improve the integrity of tool 3 and tool holder 1 and prevent tool 3 from becoming unstable.

[0033] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
