Description

Technical Field

[0001] The utility model relates to the technical field of grafting, in particular to a cutting and trimming device for horticultural grafting. Background Art

[0002] Horticultural grafting is an important asexual reproduction technology, which is widely used in horticulture and agriculture. Grafting is to graft the buds or branches of one plant onto the stems or roots of another plant so that they can heal and grow together to form a new plant body. The principle of grafting is to utilize the healing function of plants after being injured. When the cambium of the scion and the rootstock are tightly combined, the cambium cells have the ability to divide and can divide outward to produce phloem with sieve tubes inside, and divide inward to produce xylem with vessels inside. In this way, the vascular tissues of the two plants are combined into a whole.

[0003] At present, the cutting and trimming of horticultural grafting is to form the grafting part by cutting with scissors and cutting with knives, and the grafted tree needs to be pruned again. Frequent replacement of tools is inconvenient, which affects the grafting rate, and the cut is not smooth enough, which affects the quality of the grafting. Based on these problems, Chinese patent CN221010930U discloses an eggplant grafting seedling grafting device, which can combine the cutting knife and the scissors through the scissor part, the bevel groove, the buffer pad and the tooth groove, and use different grooves to trim the grafted tree and the grafted seedling to improve the cutting flatness and make the cutting angle consistent, so as to improve the quality of the grafting.

[0004] When the cutting knife is used, the scissors need to be disassembled, and the pin shaft and another set of cutting knives need to be stored. This process not only causes the pin shaft to be lost, but also makes it difficult to store the other set of cutting knives. Utility Model Content

The present invention provides the following embodiments.

[0036] Reference Figure 1-8 The utility model provides an embodiment: a cutting and trimming device for gardening grafting, comprising a handle 1, a first straight block 2 is fixedly connected to the top of the handle 1, a second straight block 3 is fixedly connected to the bottom of the handle 1, the first straight block 2 and the second straight block 3 are of the same size, a first U-shaped frame 4 is fixedly connected to both ends of the outer wall of one side of the first straight block 2, a second U-shaped frame 5 is fixedly connected to both ends of the outer wall of one side of the second straight block 3, the first U-shaped frame 4 and the second U-shaped frame 5 are of the same size, the first U-shaped frame 4 and the second U-shaped frame 5 are both installed on the outer wall of the same side of the first straight block 2 and the second straight block 3, a first slider 6 is slidably connected to the inner wall of the first U-shaped frame 4, and a second slider 7 is slidably connected to the inner wall of the second U-shaped frame 5.

[0037] The first slider 6 and the second slider 7 are fixedly connected to the opposite surfaces of the pinching rod 8. A protrusion made of sponge is installed at the center of the outer wall of one side of the pinching rod 8, which not only helps to increase the friction in the contact area between the user's hand and the pinching rod 8, but also improves the comfort of the cutting and trimming device during use. The two ends of the outer wall of one side of the pinching rod 8 are fixedly connected to the blocking rod 9. By setting the blocking rod 9, the user's hand can be prevented from falling off the pinching rod 8.

[0038] A mounting plate 10 is fixedly connected to the top of the first slider 6, and an insertion shaft 11 is vertically penetrated at both ends of the mounting plate 10. Both ends of the mounting plate 10 are provided with through holes that penetrate up and down. The outer wall of the insertion shaft 11 vertically penetrates the through holes at both ends of the mounting plate 10, and the bottom end of the outer wall of the insertion shaft 11 is threadedly connected with a nut 12. The nut 12 can be used to fix the insertion shaft 11 in the through hole inside the mounting plate 10. A double-edged cutting knife 13 is fixedly connected to the top of the insertion shaft 11.

A square cavity penetrating the outer walls on both sides is opened in the hollow frame 14. One end of the inclined surface of the outer wall of the hollow frame 14 forms a triangular angle with one end of the inner wall of the square cavity inside the hollow frame 14. Therefore, the inclined portion of the outer wall of the hollow frame 14 is in a blade state. Both ends of the outer wall of one side of the hollow frame 14 are fixedly connected to a third U-shaped frame 15. The outer wall of one side of the third U-shaped frame 15 Hollow tubes 16 are passed through at both ends, through holes are opened at both ends of the outer wall of one side of the third U-shaped frame 15, one end of the outer wall of the hollow tube 16 is installed in the through holes inside the third U-shaped frame 15, one end of the inner wall of the hollow tube 16 is slidably connected with a slide rod 17, one end of the outer wall of the slide rod 17 is sleeved with a return spring 18, and the other end of the inner wall of the hollow tube 16 is slidably connected with a vertical rod 19, the vertical rod 19 is fixedly connected to the opposite surface of the slide rod 17, and a threaded shaft 20 is fixedly connected at the center of the same end surface of the vertical rod 19.

[0040] The inner wall of the hollow frame 14 is slidably connected with a baffle 21. In the process of slowly squeezing the handle 1 and the pinching rod 8, the blade at one end of the outer wall of the double-edged cutting knife 13 will slowly approach the hollow frame 14, and at this time, the branches placed between the double-edged cutting knife 13 and the hollow frame 14 can be sheared. Both ends of the baffle 21 are penetrated by sleeves 22. When the blade at one end of the outer wall of the double-edged cutting knife 13 is inserted into the hollow frame 14, the baffle 21 can be pushed toward the other end of the inner wall of the hollow frame 14. When the double-edged cutting knife 13 is separated from the hollow frame 14, the baffle 21 will remove the debris remaining on the outer wall of the hollow frame 14. One end of the inner wall of the sleeve 22 is sleeved with one end of the outer wall of the threaded shaft 20, and the other end of the outer wall of the threaded shaft 20 is threadedly connected with a threaded cover 23. By setting a connecting structure among the threaded cover 23, the threaded shaft 20 and the sleeve 22, the baffle 21 can be fixed on the vertical pole 19.

[0041] A hollow tube 24 runs through the first straight block 2 and the second straight block 3, a limiting rod 25 is fixedly connected at the center of one side of the inner wall of the hollow tube 24, a pushing spring 26 is sleeved on one end of the outer wall of the limiting rod 25, and a hollow rod 27 is slidably connected to the other end of the outer wall of the limiting rod 25, the top end of the hollow rod 27 is fixedly connected to the outer wall on the same side of the first slider 6 and the second slider 7, the pushing spring 26 can push the hollow rod 27, and at the same time, the pinching rod 8 between the first slider 6 and the second slider 7 can be quickly reset.
