Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural tools, and particularly relates to a grafting scissors with an accurate cutting surface angle. Background Technique

[0002] Grafting technology is an important artificial propagation method. By grafting the branch or bud of a plant onto the stem or root of another plant, the two are joined together and grow into a complete plant. The main purposes of this technology are to improve the quality of fruits and vegetables, shorten their growth period, increase yield, and change the production season, etc. When grafting, it is necessary to ensure the angle and flatness of the joint part (i.e., the cutting surface) so that the rootstock and scion can fit tightly, thereby improving the survival rate and effect of grafting.

[0003] When traditional grafting scissors cut branches, it is often difficult to ensure the consistency of the cutting surface angle, resulting in a low fitting degree between the rootstock and scion, affecting the grafting effect. At the same time, when some grafting scissors are used, the fixation of the rootstock and scion is unstable and requires multiple adjustments, which not only takes time and effort but also increases the operation difficulty and time cost of the user. Content of the Utility Model

[0031] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0032] Please refer to Figures 1 to 5 As shown, a grafting scissors with precise cutting surface angle includes a lower scissors frame 1 and an upper scissors frame 2. The lower scissors frame 1 is composed of a bottom plate 11, a first hinge portion 12 and a handle portion 13. The rear end of the bottom plate 11 is connected to the front end of the first hinge portion 12, and the rear end of the first hinge portion 12 is connected to the front end of the handle portion 13. The upper scissors frame 2 is composed of a second hinge portion 21, a blade mounting portion 22 and a pressing handle portion 23. The rear end of the blade mounting portion 21 is connected to the front end of the second hinge portion 22, and the rear end of the second hinge portion 22 is connected to the front end of the pressing handle portion 23. The first hinge portion 21 of the lower scissors frame 1 is rotatably connected to the second hinge portion 22 of the upper scissors frame 2 by a rivet. By making the handle portion 13 and the pressing handle portion 23 approach and move away from each other, the opening and closing of the grafting scissors are realized.

[0033] As Figure 1 shown, an installation groove 211 is provided on the blade mounting portion 21 of the upper scissors frame 2, and a blade 3 is vertically installed in the installation groove 211 in a detachable manner by screws. The detachable design facilitates the user to replace the blade 3.

[0034] As Figures 1 to 4As shown in the figure, a supporting mechanism 4 is provided below the blade 2 above the bottom plate 11. The supporting mechanism 4 includes a fixing plate 41, a placing plate 42 and a protractor 43. The fixing plate 41 is installed on the upper surface of the bottom plate 11, and the right end of the fixing plate 41 is directly below the cutting edge of the blade 3. The placing plate 42 is rotatably connected to the upper surface of the right end of the fixing plate 41 through a hinge seat. The placing plate 42 can rotate around the horizontal straight line where the rivet on the hinge seat is located. Protractors 43 are fixedly installed at the front end and the rear end of the fixing plate 41 respectively. The protractor 43 is a quarter-circular plate. The right-angle points of the two protractors 43 are on the same straight line as the rotating shaft, and the right-angle bottom edge of the protractor 43 is parallel to the upper surface of the bottom plate 41. The protractor 43 is provided with scales 431 with angle values, ranging from 0 degrees to 90 degrees, such as Figure 2 As shown in the figure, a quarter-circular sliding groove 432 is also opened on the protractor 43. Threaded columns 421 are fixedly connected to the front and rear ends of the placing plate 42 and corresponding to the vertical central axis. The threaded columns 421 can pass through the sliding groove 432, and each threaded column is fixedly connected to the protractor 43 on the same side through two nuts. By installing the protractors 43 at the front and rear ends of the fixing plate 41, the angle between the placing plate 42 and the blade 3 can be accurately adjusted to 30 degrees, thus meeting the requirements of the user.

[0035] A placing groove 422 for placing branches of different thicknesses is opened on the surface of the placing plate 42 close to the blade 3. The length direction of the placing groove 422 is perpendicular to the length direction of the blade 3. A layer of protective pad is also laid on the surface of the placing groove 422 to prevent damage to the outer epidermis of the rootstock seedlings or scion seedlings when the branches are placed in the placing groove 422 for cutting.

[0036] A support rod 44 is rotatably connected to the surface of the placing plate 42 close to the bottom plate 41. The end of the support rod 44 away from the placing plate 42 is hingedly connected to a suction cup 45. A smooth first groove 411 is opened on the upper surface of the fixing plate 41. The suction cup 45 can be adsorbed on the bottom wall of the first groove 411. Through the arrangement of the support rod 44 and the suction cup 45, the placing plate 42 can be further supported at a fixed angle to prevent displacement of the placing plate 42 during cutting of the rootstock seedlings or scion seedlings, resulting in inaccurate cutting.

[0037] A fixing component 5 is provided near the upper end of the placing plate 42 and directly above the placing groove 422. The fixing component includes a pressing rod 51, a stop block 52, and a spring 53. The pressing rod 51 is a U-shaped rod composed of a transverse rod 511 and two vertical rods 512, and the pressing rod 51 is integrally formed. Vertical through holes 423 are correspondingly formed on both sides of the placing groove 422 on the placing plate 42. The two vertical rods 512 of the pressing rod 51 are respectively inserted into the two through holes 423. Stop blocks 52 are installed at both ends of the two vertical rods 512. A spring 53 is sleeved around the vertical rods 512 between the stop blocks 52 and the placing plate 42. Different thickness branches can be fixed between the transverse rod 511 and the placing groove 422 through the spring 53, preventing the rootstock seedlings or scion seedlings from moving during cutting.

[0038] A side protection pad is laid on the opposite side walls of the transverse rod 511 and the placing groove 422 to prevent the transverse rod 5112 from damaging the outer skin of the rootstock seedlings or scion seedlings when fixing them.

[0039] Working principle:

[0040] When using this grafting scissors, first check whether the blade 3 can be used. If the blade 3 needs to be replaced, first remove the screw, then remove the old blade, replace it with a new blade, press on the screw and tighten it. Then loosen the nut connected to the threaded column 421, rotate the angle of the placing plate 42 so that the angle between the placing plate 42 and the vertical level is 30 degrees. Then screw the nut back onto the threaded column 421, and use the support column 44 and the suction cup 45 to support the placing plate 42. Then pull the pressing rod 51. Place the rootstock seedlings or scion seedlings to be cut in the placing groove 422, and release the pressing rod 51. Use the elasticity of the spring 53 to fix the rootstock seedlings or scion seedlings to be cut in the placing groove 422. Finally, hold the handle part 13 and the pressing handle part 23 with the hand and tightly hold the pressing handle part 23 upward, so that the blade 3 moves downward to cut the rootstock seedlings or scion seedlings. Then pull the pressing rod 51 outward to take out the cut rootstock seedlings or scion seedlings. At this time, the cutting surfaces of the rootstock seedlings or scion seedlings are both 30 degrees.

[0041] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the technical content of the present invention, many changes can be made in the specific implementation manner and application scope. As long as these changes do not depart from the concept of the present invention, they all belong to the protection scope of this patent.
