Description

Technical Field

[0001] The utility model belongs to the technical field of gardening and greening, and in particular relates to a gardening and greening grafting device. Background Art

[0002] Grafting is one of the artificial propagation methods of plants, that is, grafting the scion of one plant onto the rootstock of another plant so that the two connected parts grow into a complete plant. Grafting is carried out by utilizing the healing function of plants after being injured. Branches are grafted during garden greening, and a grafting knife is one of the most basic tools in the grafting process. Its function is to cut the mother plant and the scion of the branch and merge them into a whole. The Chinese patent application number 201922300014.6 discloses a grafting knife for garden greening. It can be seen that the content describes a garden greening grafting device.

[0003] When the existing garden greening grafting device is in use, a person holds the knife handle and then cuts the rootstock through the knife body, and then completes the grafting operation. When the grafting is completed, the person will throw the grafting knife aside casually. At this time, the sharp edge of the bottom of the knife body on the grafting knife is exposed. When the person accidentally touches the sharp edge, it may cause scratches on the fingers. At this time, the edge is easy to scratch the fingers of the person and cause injuries, which reduces the operating experience of the person. In addition, if the blade first contacts other objects when the grafting knife is thrown aside, it will also cause bumps and damage to the blade. For this reason, we propose a garden greening grafting device. Utility Model Content

[0029] The working principle and use process of this utility model:

[0030] After the grafting is completed, when the personnel casually throws the grafting knife aside, the bottom of the baffle 200 and the rubber protection strip 207 will exceed the distance of the cutting edge below the knife body 101, and the cutting edge is protected by the baffle 200 and the rubber protection strip 207. In addition, when the hand of the subsequent personnel is about to accidentally touch the cutting edge of the grafting knife thrown aside, the hand of the personnel will contact the baffle 200 and the rubber protection strip 207, reducing the probability of the cutting edge scratching the fingers of the personnel. When the personnel holds the knife handle 100 and uses the knife body 101 to cut the branch, the cutting edge at the bottom of the knife body 101 is cut toward the branch. When it is about to touch the branch, the rubber protection strip 207 at the bottom of the baffle 200 contacts the branch, and the baffle is driven to move. The vertical rod 206 on 200 moves upward, and the fixing spring 205 is affected by the movement of the fixing ring 204 on the vertical rod 206 and begins to compress, and then the cutting edge is exposed, and then the cutting edge contacts and cuts the branch. When the cutting is completed, the branch is removed, and the fixing spring 205 is reset. At this time, the baffle 200 and the rubber protection strip 207 at the bottom of the baffle 200 move downward to restore to the original position, and the cutting edge can be blocked and protected. After the nut rings 202 at both ends of the horizontal screw 203 are unscrewed outward, the horizontal screw 203 is moved outward and taken out, and the protective parts and mounting blocks 201 on the blocking mechanism can be removed. According to the above-mentioned reverse principle, it can be installed and used according to different situations.

[0031] The strength of the blade body 101 can be increased during use, and the probability of the blade body 101 being bent and damaged during use can be reduced;

[0032] When the stock 102 is cut for grafting, the knife body 101 is placed horizontally at the appropriate position of the stock 102 and cut, and then the clamping ring 406 is sleeved on the stock 102 from the cut stock 102, and then the spiral rod is rotated and tightened in the direction of the stock 102, so that the grafting knife and the stock 102 can be connected and fixed together, and then the grafting knife is moved downward, driving the side ring 400 and the knife body 101 to move, and at this time, the mounting spring 401 begins to be compressed by the downward extrusion force of the side ring 400, and finally the cutting edge below the knife body 101 can contact the top of the stock 102 and cut a hole therein, and then the grafting knife is released, and at this time the mounting spring 401 is reset to restore the grafting knife to its original position, and then the spiral rod is rotated outward and loosened, and the clamping ring 406 is moved upward to leave the top of the stock 102, and then the scion is inserted into the cut hole, and the stock 102 and the scion are wrapped together with the winding film to complete the grafting operation.
