[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-3The utility model provides a kind of adjustable distance garden budding tool knife, including tool knife structure 1, tool knife structure 1 includes knife handle 11, the surface of knife handle 11 is provided with bandage 111, and the surface of bandage 111 is provided with anti-skid lines, the upper left corner of the handle end of knife handle 11 is connected with threaded seat 112 by bolt, and is threadedly connected with distance adjusting rod 12 in cooperation with threaded seat 112, distance adjusting rod 12 is composed of handle, screw rod and edge rod, wherein, the rod end of edge rod is slidably limited in the edge hole of the inside of connecting shaft 121, and connecting shaft 121 is rotatably arranged in the inside of knife handle 11, connecting shaft 121 is fixed with the shaft end of rotating shaft 141 after extending out of knife handle 11, rotating shaft 141 is integrally arranged on the upper surface front half of rotating knife 14, and the upper side of rotating knife 14 is movably connected with main cutter 13 by the rotary connection of the both ends of rotating shaft 141 in the inside of shaft sleeve 131, shaft sleeve 131 is integrally arranged on the upper side of main cutter 13, and is arranged corresponding to the both ends of rotating shaft 141, the handle end of main cutter 13 is inserted in the inside of knife handle 11, and is fixed in the inside of knife handle 11 by bolt, the lower surface of rotating knife 14 is integrally provided with drumming auxiliary knife 142, drumming auxiliary knife 142 is arranged according to the path of main cutter 13 towards the side of main cutter 13, and is closely attached to the right side of main cutter 13 by the setting path of the abutting surface, and drumming auxiliary knife 142 is right side lofted in the connecting position with rotating knife 14, so that the right side of drumming auxiliary knife 142 has undulating camber, the tip of main cutter 13, rotating knife 14 and drumming auxiliary knife 142 is provided as sharp knife, and the tip is inclined surface from front to back and from top to bottom, the upper side of main cutter 13 and rotating knife 14 is provided as cutting edge from the tip to shaft sleeve 131.

[0022] When working, first manually rotate distance adjusting rod 12 to drive connecting shaft 121 and rotating shaft 141 to make rotating knife 14 rotate, adjust the distance from main cutter 13 to adapt to sapling;When grafting, operator holds knife handle 11 and uses main cutter and rotating knife tip to pierce epidermis, and breaks the skin under the adjusted knife distance;Conventional use can also directly cut horizontally, and drumming auxiliary knife 142 moves with rotating knife 14 to help epidermis drumming bag during the process, to complete the early preparation of budding.

[0023] In summary, by precisely controlling the distance adjustment between the rotary knife 14 and the main cutting knife 13 through the distance adjusting rod 12, it can quickly adapt to the changes in the thickness of different saplings. Compared with traditional fixed distance tools, it greatly expands the application range. Whether it is a delicate flower branch or a sturdy fruit tree branch, it can easily cope with it. This not only significantly reduces the problems of bark tearing and irregular cuts caused by mismatched knife distance, reducing the risk of damage to the sapling, but also plays an important role in the conventional use of the drum-shaped auxiliary knife 142. Its design of closely attaching to the main cutting knife 13 and moving with the rotary knife 14 forms a drum shape, creating extremely favorable conditions for subsequent scion fitting. During the cross-cut operation, the drum-shaped auxiliary knife 142 naturally and smoothly makes the sapling skin bulge, forming a regular drum shape with high adhesion. Compared with the simple cutting operation of ordinary tools, it can make the scion and stock have a larger contact area and tighter adhesion during grafting, significantly enhancing the connection stability of the grafting site. This is conducive to the transmission of nutrients and water, promotes wound healing, effectively improves the grafting survival rate, and ensures the growth quality and ornamental effect of horticultural plants, improving the quality and efficiency of horticultural work results.

[0024] Meanwhile, the contents not described in detail in the specification are all prior art known to those skilled in the art.

[0025] Working principle: When working, first manually rotate the distance adjusting rod 12 to make the screw part of the distance adjusting rod 12 rotate inside the threaded seat 112, and during rotation, the coaxially matched rib rod part drives the connecting shaft 121 to rotate, which in turn drives the rotary shaft 141 to rotate, so that the rotary knife 14 rotates in the shaft sleeve 131 with the rotary shaft 141 as the axis, thereby realizing the unfolding or closing action of the main cutting knife 13 and the rotary knife 14 to adjust the distance between them to adapt to the grafting needs of saplings of different thicknesses; during grafting operation, the operator holds the knife handle 11 with both hands, and uses the anti-slip pattern on the binding strap 111 to hold it firmly, aligns the tips of the main cutting knife 13 and the rotary knife 14 with the sapling skin, and uses the sharp knife shape with a beveled design to easily penetrate the skin. Subsequently, according to the adjusted knife distance, the main cutting knife 13 and the rotary knife 14 are chiseled down along the sapling skin. Since the position of the blade from the tip to the shaft sleeve 131 is reasonable, it can efficiently break the skin; during conventional use (such as Figure 1 As shown, the distance between the main cutting knife 13 and the rotary knife 14 can not be adjusted, and the conventional method of cutting down can be used. During the cross-cutting process, the drum-shaped auxiliary knife 142 closely adheres to the right side of the main cutting knife 13 and moves with the rotary knife 14. The undulating arc helps to form a certain drum shape on the sapling skin while breaking the skin, facilitating the subsequent fitting and grafting operation of the scion, thereby completing the preliminary work of horticultural budding.
