Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double-tongue grafting, in particular to a grafting knife used for grafting walnuts using a double-tongue grafting method. Background Art
[0002] Grafting is to graft the branches or buds of one plant onto the stems and roots of another plant so that the two parts grow into a complete plant. Grafting is of great significance for the improvement of varieties and the improvement of economic value. Grafting usually uses branches with similar thickness and smoothness, cuts off a part of each, and then aligns the cambium of the cuts on both sides and tightens them with plastic film. In the prior art, when cutting branches, usually a tool is used to cut the branches, and then the branches are cut manually with a tool. When cutting manually, it is usually done by feeling, which can easily cause the cutting surface of the branches to be of different sizes, thereby affecting the survival rate of the graft. Utility Model Content
[0003] The utility model aims to provide a grafting knife for grafting walnuts by a double-tongue grafting method. During grafting, the knife can conveniently cut support rods of different thicknesses, ensure the size of the incisions is consistent, and improve the survival rate of the grafting.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A grafting knife for grafting walnuts by double-tongue grafting method, comprising a shell, a first limiting rod is horizontally arranged inside the shell, a first gear is rotatably connected to the outer side of the first limiting rod, a first gripping rod slidably connected to the shell is arranged on the outer side of the first gear, a second gripping rod is arranged at one end of the shell close to the first gripping rod, a first rack arranged horizontally is slidably connected to one end of the shell close to the first gripping rod, a second gear meshing with the first gear is rotatably connected to the left and right ends of the first gear at one end of the shell close to the first gear, and a clamping device is arranged at one end of each second gear;
[0006] A limiting groove is provided at the upper end of the first rack, a second limiting rod is horizontally arranged inside the limiting groove, a slider slidably connected to the limiting groove is slidably connected to the outer side of the second limiting rod, a first spring is arranged between the end of the slider close to the first gripping rod and the limit on the outer side of the second limiting rod, and a connecting rod rotatably connected to the slider is rotatably connected to the end of the first gripping rod close to the first gear;
[0007] The inner end of the shell away from the first rack is slidably connected with a second rack meshing with the first gear, the end of the second rack away from the first grip is provided with a limiting sleeve, the inner part of the limiting sleeve is slidably connected with a first limiting block, the end of the first limiting block away from the first grip is horizontally provided with a third limiting rod slidably connected with the limiting sleeve, the outer side of the third limiting rod is provided with a second spring between the end of the first limiting block away from the first grip and the limiting sleeve, the end of the third limiting rod away from the first grip is provided with a clamping block, and the end of the clamping block away from the limiting sleeve is provided with a blade.
[0008] By adopting the above technical solution, when cutting branches, select the branches to be grafted, and then hold the first gripping rod and the second gripping rod by hand, pull the first gripping rod to move, the first gripping rod drives the first gear to rotate relative to the first limiting rod, the first gripping rod drives the connecting rod to rotate relative to it, and at the same time, by pulling the connecting rod to move, the movement of the connecting rod drives the slider to move relative to the limiting groove, which will compress the first spring. Due to the elastic force generated by the first spring, the slider can drive the first rack to slide relative to the outer shell, the first rack drives the second gear to rotate, and the rotation of the second gear drives the clamping device to clamp the branch, and the first gear simultaneously drives the second rack to slide relative to the outer shell, and the second rack drives the blade to move to cut the support rod, so that when cutting branches of different thicknesses. After the clamping device clamps the branch, the first grip can still drive the connecting rod to move. After the clamping device clamps the branch, the second gear cannot rotate, and the movement of the first rack is also restricted. The connecting rod drives the slider to slide relative to the second limit rod to ensure that branches of different thicknesses can be cut. The third limit rod is driven to move relative to the limit sleeve by pulling the clamp block, and the first limit block is driven to move to compress the second spring. Then, rotating the clamp block can change the cutting angle of the blade. Releasing the clamp block can drive the clamp block to reset under the action of the second spring elastic force. During the resetting process of the first grip, the first spring can drive the slider to reset, and then the first grip continues to move to drive the slider and the first rack to move through the connecting rod.
[0009] The utility model is further configured as follows: the clamping device comprises a clamping rod horizontally arranged at the upper end of each first gear, and an arc-shaped clamping plate is rotatably connected to one end of each clamping rod away from the first gripping rod.
[0010] The utility model is further configured as follows: a plurality of equally spaced limiting holes are provided at one end of the limiting sleeve close to the clamping block, and a plurality of equally spaced second limiting blocks corresponding to the limiting holes and slidably connected are provided at one end of the clamping block close to the limiting sleeve.
[0011] The utility model is further configured as follows: a rubber sleeve is provided on one end of the first gripping rod away from the housing and on one end of the second gripping rod away from the housing.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] First, it is convenient to cut branches of different thicknesses while ensuring that the size of the incision is consistent, thereby improving the survival rate of grafting. The first spring can be compressed by driving the slider to slide through the connecting rod, and the first rack can be driven to move under the action of the elastic force of the first spring. The first rack drives the second gear to drive the arc-shaped clamping plate to clamp the branch. The first gear rotates to drive the rack to move, and the rack drives the blade to cut the branch to ensure that the size of the branch incision is consistent. When clamping branches of different thicknesses, the second gear cannot rotate, and the first rack cannot slide. The movement of the first grip can continue to drive the slider to slide in the limit groove through the connecting rod, thereby preventing the blade from failing to complete the cutting of the branch.
[0014] Secondly, the cutting angle can be adjusted as needed. The clamping block drives the first limit block to compress the spring, and the clamping block drives the second limit block to move out of the limit hole. Then the clamping block can be rotated. After adjusting the angle, the second limit block is driven into the limit hole under the action of the second spring, thereby completing the adjustment of the blade angle.
