DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Refer to the attached specification Figure 1-4 The utility model is a grafting point fixing device for hazel grafting, comprising a top plate 1 and a bottom plate 2, see Figure 1 , two bolts 3 are inserted into the top plate 1 and the bottom plate 2, and a first connecting plate 4 and a second connecting plate 5 are arranged between the top plate 1 and the bottom plate 2, one of the bolts 3 is connected to the inside of the first connecting plate 4 by thread, and the other bolt 3 is connected to the inside of the second connecting plate 5 by thread, see Figure 3 The top plate 1 has two first sliders 6 slidably connected inside, and the two first sliders 6 have bidirectional threaded rods 7 threadedly connected inside, and the bidirectional threaded rods 7 are rotatably connected inside the top plate 1, and the two first sliders 6 are both slidably connected inside with first connecting blocks 8, and one side of the first connecting block 8 is fixedly connected with a clamping rod 9, and the clamping rod 9 is arranged between the first connecting plate 4 and the second connecting plate 5;

[0023] See Figure 4One end of the clamping rod 9 is fixedly connected to a second connecting block 10, and the outer wall of the second connecting block 10 is slidably connected to a second slider 11, and the second slider 11 is slidably connected to the inside of the bottom plate 2. The inside of the second slider 11 is connected to a threaded rod 12 through a thread, and the threaded rod 12 is rotatably connected to the inside of the bottom plate 2. For details, see Figure 3 A fixing rod 13 is inserted into the interior of the top plate 1 and the bottom plate 2, a wrapping belt 14 is sleeved on the outer wall of the fixing rod 13, and a plurality of supporting rods 15 are inserted into the interior of the wrapping belt 14.

[0024] It should be noted that, when the staff has completed the grafting of the hazel tree and needs to fix the grafting point, the winding belt 14 can be wound around the grafting point, and the excess winding belt 14 can be passed through the gap between the first connecting plate 4 and the second connecting plate 5, and the winding belt 14 can be tightened so that the winding belt 14 cooperates with the first connecting plate 4 and the second connecting plate 5 to be sleeved on the outer wall of the grafting point. Then the user can rotate the bidirectional threaded rod 7 so that the bidirectional threaded rod 7 drives the two first sliders 6 to gradually approach each other through the threads, and then the first slider 6 drives the two clamping rods 9 to approach each other through the first connecting block 8, so that the two clamping rods 9 are stuck between the two adjacent support rods 15 of the winding belt 14, and the winding belt 14 is tightened. The wrapping belt 14 is used for clamping and fixing, and finally the user rotates the threaded rod 12, so that the threaded rod 12 drives the second slider 11 to slide along the inside of the bottom plate 2 through the thread, and the second slider 11 drives the clamping rod 9 to move through the second connecting block 10, so that the clamping rod 9 clamped between two adjacent support rods 15 is further tightened by pulling the wrapping belt 14 through the support rod 15, and the grafting point of the hazel tree is wrapped and fixed, so as to prevent the wrapping belt from falling along the outer wall of the grafted hazel tree, and prevent the grafted hazel tree from being separated by external influences (such as wind, rain and impact, etc.), resulting in grafting failure, and the grafting points of grafted hazel trees of different thicknesses can be wrapped and fixed, thereby improving the application range of the fixing device;

[0025] Furthermore, when the grafting points of the hazel tree grow together and the fixing device needs to be removed, the staff can rotate the two-way threaded rod 7 in the opposite direction, so that the two-way threaded rod 7 drives the two first sliders 6 to gradually move away from each other through the threads, and then the first slider 6 drives the two clamping rods 9 to move away from each other through the first connecting block 8, and stops being clamped between the two adjacent support rods 15 of the winding belt 14, so that the staff can pull the winding belt 14 out from between the first connecting plate 4 and the second connecting plate 5, so as to achieve the effect of quickly disassembling the fixing device, which is convenient for the staff to use, and can be reused to bandage and fix the grafting points of subsequent grafted hazel trees.
