[0002] Fruit planting refers to the process of cultivating and producing various types of fruits under suitable land and environmental conditions through a series of agricultural technologies and management measures. Generally, in order to improve fruit varieties, enhance the adaptability of fruit trees and shorten the fruiting cycle, grafting is often used to splice branches of different fruit trees. After the grafting is completed, in order to maintain the close combination of the scion and the rootstock, reduce external interference and promote wound healing, corresponding grafting fixing devices are often used to fix the grafting point and the corresponding branches.

[0003] According to the utility model of authorization announcement number CN215530126U, a grafting point fixing device for cherry tree grafting is disclosed. Although the fixing device can fix the fixing device and the upper and lower parts of the grafting point through a binding device and a clamping device, which is convenient for displaying the growth progress of the plant before and after grafting, and can fix the plants above and below the grafting point, so that the success rate of grafting is increased, it needs to be manually disassembled in the later stage, and lacks an automatic detaching structure that can automatically detach from the clamping and fixing of the grafted branches and trunks, resulting in a long time of binding at the grafting place and not being untied in time, which is easy to cause adverse effects on the normal growth of the branches and trunks; for this reason, we provide a grafting fixing device for fruit planting to solve the above problems.

[0008] Furthermore, each of the fixed cylinders is slidably connected to a top plate, the inner wall of each top plate is fixedly connected to an auxiliary bearing, and both ends of each return spring are in contact with the outer surface of the push rod and the outer surface of the top plate respectively.

[0009] Furthermore, the inner wall of each fixing tube is threadedly connected with a hand bolt, and the outer surface of each hand bolt is fixedly connected to the inner ring of the auxiliary bearing.

[0022] The present embodiment provides a grafting fixing device for fruit planting, which is used to fix the grafting point of branches during the fruit planting process. After the grafting point becomes thicker to a certain extent as the branch grows, it can automatically detach from the grafting point of the branch, effectively preventing the grafting point of the branch from being excessively clamped and fixed, which may cause adverse effects on the growth and development of the fruit branches.

By providing the anti-skid protrusions 5, the anti-skid property of the outer surfaces of the first anti-skid pads 4 can be increased. By providing the first anti-skid pads 4 and the anti-skid protrusions 5, the anti-skid property of the outer surfaces of the first docking block 301 and the second docking block 302 can be jointly increased, thereby facilitating the grasping of the first docking block 301 and the second docking block 302.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Each fixed cylinder 307 is slidably connected to a push rod 308, each fixed cylinder 307 is provided with a return spring 310, each fixed cylinder 307 is slidably connected to a top plate 8, the inner wall of each top plate 8 is fixedly connected to an auxiliary bearing 9, and the two ends of each return spring 310 are in contact with the outer surface of the push rod 308 and the outer surface of the top plate 8 respectively. By providing the top plate 8, it can slide inside the fixed cylinder 307, and then after cooperating with the auxiliary bearing 9 and other structures, the initial telescopic state of the return spring 310 can be adjusted.

[0025] Reference Figure 1 , Figure 2 , Figure 3, Figure 4 and Figure 5 The ends of the two push rods 308 close to each other are fixedly connected with an arc-shaped clamping plate 309, and the left side of the first docking block 301 is fixedly connected with four positioning columns 303. The inner wall of each fixed cylinder 307 is threadedly connected with a hand-tightening bolt 10, and the outer surface of each hand-tightening bolt 10 is fixedly connected to the inner ring of the auxiliary bearing 9. By providing the hand-tightening bolt 10, it is convenient to tighten the hand-tightening bolt 10 after being pinched by hand, so that it can rotate along the inner wall of the fixed cylinder 307, and with the cooperation of the auxiliary bearing 9, it is convenient to adjust the position of the top plate 8 in the fixed cylinder 307, and then it can cooperate with the push rod 308 to control the initial extension and contraction state of the return spring 310, thereby controlling the initial tightening force of the push rod 308 and the arc-shaped clamping plate 309 on the first branch 1 and the second branch 2, so as to adjust the clamping force of the first branch 1 and the second branch 2.

[0026] Reference Figure 2 , Figure 4 and Figure 5 The left end of each positioning column 303 is fixedly connected to a first magnetic block 304, and the outer surface of each top plate 8 is fixedly connected to two first limit sliders 11. The outer surface of each first limit slider 11 is slidably connected to the inside of the fixed cylinder 307. By providing the first limit slider 11, it can slide inside the fixed cylinder 307, thereby increasing the sliding stability and directionality of the top plate 8 in the fixed cylinder 307.

[0027] Reference Figure 3 and Figure 4 Four positioning grooves 305 are provided on the right side of the second docking block 302. The outer surface of each push rod 308 is fixedly connected to the second limiting slider 7. The outer surface of each second limiting slider 7 is slidably connected to the inside of the fixed cylinder 307. By providing the second limiting slider 7, it can slide inside the fixed cylinder 307, thereby increasing the sliding stability and directionality of the push rod 308 in the fixed cylinder 307.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of each positioning groove 305 is fixedly connected with a second magnetic block 306, and the inner wall of each arc-shaped clamping plate 309 is fixedly connected with a second anti-slip pad 6. The inner wall of each second anti-slip pad 6 is in contact with the outer surface of the first branch 1 and the outer surface of the second branch 2 respectively. By providing the second anti-slip pad 6, the anti-slip property of the inner wall of the arc-shaped clamping plate 309 can be increased, thereby making the two arc-shaped clamping plates 309 more stable when clamping and fixing the first branch 1 and the second branch 2.

[0029] Working principle: When in use, the first docking block 301 and the second docking block 302 are placed around the grafting of the first branch 1 and the second branch 2, and the first magnetic block 304 and the second magnetic block 306 are quickly docked through the docking of the positioning column 303 and the positioning groove 305 and the magnetic attraction of the first magnetic block 304 and the second magnetic block 306. During this period, the second anti-slip pads 6 on the two arc-shaped clamping plates 309 clamp the grafting of the first branch 1 and the second branch 2 tightly, and the two arc-shaped clamping plates 309 are elastically returned to the top by the return spring 310. The first branch 1 and the second branch 2 are stably clamped and fixed, and then the initial clamping force of the arc clamping plate 309 is adjusted according to the thickness of the first branch 1 and the second branch 2. When the first branch 1 and the second branch 2 are thin, the hand-tightening bolt 10 is screwed along the inner wall of the fixing tube 307 to make the return spring 310 gradually compressed by the top plate 8 and the top rod 308 until the initial clamping force of the two arc clamping plates 309 can better clamp the thin first branch 1 and the second branch 2. That is, when the first branch 1 and the second branch 2 are thicker, the hand-tightening bolt 10 can be screwed in the reverse direction according to the above process. As the first branch 1 and the second branch 2 grow and become thicker, the return spring 310 will be gradually compressed, thereby alleviating the squeezing state of the first branch 1 and the second branch 2 grafting point to a certain extent, until the rebound force of the return spring 310 gradually exceeds the magnetic attraction force of the first magnetic block 304 and the second magnetic block 306, and the first docking block 301 and the second docking block 302 are gradually separated, thereby realizing the clamping and disengagement of the first branch 1 and the second branch 2 grafting point, playing the role of automatically disengaging the clamping and fixing of the first branch 1 and the second branch 2 grafting point to help the normal growth of the fruit tree branches and trunks. The design of the entire fruit planting grafting and fixing device effectively solves the problem that the lack of an automatic detaching structure that can automatically detach from the clamping and fixing of the grafted branches and trunks leads to an adverse effect on the normal growth of the branches and trunks when they are tied at the grafting point for a long time and are not untied in time.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
