The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0016] like Figure 1 , Figure 2 As shown, a fruit tree grafting and fixing device comprises two groups of clamping assemblies 1 arranged in an upper and lower manner and a support member 2 for connecting the two groups of clamping assemblies 1, the support member 2 is detachably connected to the two groups of clamping assemblies 1, each group of clamping assemblies 1 comprises two arc-shaped clamping plates 11 arranged opposite to each other and elastic bands 12 arranged at both ends of one of the arc-shaped clamping plates 11, one end of the elastic band 12 is connected to the arc-shaped clamping plate 11, and the other end of the elastic band 12 is hinged with a T-shaped fastener 121, and locking seats 13 fastened with the T-shaped fastener 121 are correspondingly provided on the outer walls of both ends of the other arc-shaped clamping plate 11, a first clamping groove 131 for the vertical rod portion of the T-shaped fastener 121 to be clamped into the middle portion of the locking seat 13, a second clamping groove 132 for the horizontal rod portion of the T-shaped fastener 121 to be clamped into the lower portion of the locking seat 13 away from one end of the T-shaped fastener 121, and the position of the locking seat 13 along the circumferential direction of the arc-shaped clamping plate 11 is adjustable.

[0017] Elastic members 110 with semi-arc cross sections are arranged at intervals on the inner wall of the arc-shaped clamping plate 11. The elastic members 110 are made of rubber material. When fixing, the elastic members 110 are in contact with the branches. The elasticity of the rubber ensures that the inner surface of the arc-shaped clamping plate 11 can be in close contact with branches of different shapes, providing tight fixation and avoiding damage to the surface of the branches when fixing.

[0018] The support member 2 includes a connecting rod 21 and a first bolt 23. A sleeve 22 for inserting the connecting rod 21 is vertically extended on the arc-shaped clamping plate 11. The sleeve 22 is passed through from top to bottom. The connecting rod 21 and the sleeve 22 are fixed by the first bolt 23. This structure facilitates the adjustment of the depth of the connecting rod 21 extending into the sleeve 22, thereby adjusting the spacing between the two groups of clamping assemblies 1. Since the connecting rod 21 and the sleeve 22 are fixed by the first bolt 23, they can be detachably fixed, so that each group of clamping assemblies 1 can be used separately to meet different fixing requirements.

[0019] The length of the transverse rod of the T-shaped fastener 121 is greater than the height of the locking seat 13. This structure allows the two ends of the transverse rod of the T-shaped fastener 121 to extend out of the two ends of the locking seat 13, making it easy to pull the T-shaped fastener 121 during operation.

[0020] The locking seat 13 is fixed on the fixing plate 14, and the arc-shaped clamping plate 11 has a slide groove 15 that slides with the fixing plate 14, and the two ends of the fixing plate 14 are fastened by second bolts 16. After loosening the second bolt 16, the position of the locking seat 13 can be adjusted along the slide groove 15, and then the second bolt 16 can be tightened, so as to adapt to the fixing of branches with different diameters.

[0021] When in use, after adjusting the position of the rear locking seat 13, the arc-shaped clamping plate 11 is aligned with the grafting position, and then the elastic band 12 is pulled so that the T-shaped fastener 121 on the elastic band 12 is stuck in the second slot 132 of the locking seat 13 for fixation, so that the elastic part 110 on the inner surface of the arc-shaped clamping plate 11 is tightly fitted with the surface of the branch to form a clamping state. When disassembling, pull the T-shaped fastener 121 to make it fall off the second slot 132. Compared with the fixing method with bolts, it is more convenient for disassembly and assembly.

[0022] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
