Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2A grafting tool for apple tree seedlings includes a tool sheath 1. Two symmetrically distributed tool holders 2 are slidably fitted inside the tool sheath 1. A blade 3 is fixedly connected to the outer side of each tool holder 2. A connecting block 4 is fixedly connected to the top of each tool holder 2. The connecting block 4 is slidably fitted onto the top of the inner wall of the tool sheath 1. A connecting groove 10 is formed on the top of the inner wall of the tool sheath 1. The connecting block 4 is slidably fitted inside the connecting groove 10. The connecting groove 10 allows the connecting block 4 to slide along it. A limiting groove 5 is formed on the top of the connecting block 4. An arc groove 6 is formed on the outer side of the tool sheath 1. Arc grooves 6 are formed on both the top and bottom of the tool sheath 1 and are evenly distributed on the outer side of the tool sheath 1. The arc grooves 6 facilitate gripping and use of the tool sheath 1. A connecting sleeve 7 is slidably fitted onto the outer side of the tool sheath 1. A limiting mechanism 8 is provided on the tool sheath 1, and a connecting mechanism 9 is provided on the connecting sleeve 7.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The limiting mechanism 8 includes a fixed base 81. Two symmetrically distributed fixed bases 81 are fixedly connected to the top of the tool holder 1. A limiting rod 82 is slidably sleeved inside the fixed base 81. The limiting rod 82 passes through the tool holder 1 and is slidably connected to the tool holder 1. A pull rod 83 is fixedly connected to the top of the limiting rod 82. The pull rod 83 passes through the fixed base 81 and is slidably connected to the fixed base 81. A first spring 84 is provided on the outside of the pull rod 83. One end of the first spring 84 is fixedly connected to the limiting rod 82, and the other end of the first spring 84 is fixedly connected to the fixed base 81. By designing the first spring 84, the elastic force of the first spring 84 can act on the limiting rod 82. A magnetic block 85 is fixedly connected to the outside of the limiting rod 82. The magnetic block 85 is slidably connected to the fixed base 81. A magnet 86 is fixedly connected to the inner side wall of the fixed base 81. By designing the limiting mechanism 8, it is convenient to limit and lock the tool holder 2.

[0020] Please see Figure 1 , Figure 2 , Figure 4 The connecting mechanism 9 includes slots 91 at both ends of the blade sleeve 1. A retaining ball 92 is movably fitted inside the slot 91 and is movably connected to the connecting sleeve 7. A clamping block 93 is movably fitted outside the retaining ball 92 and is slidably connected to the connecting sleeve 7. A spring ball 94 is fixedly connected outside the clamping block 93 and is fixedly connected to the connecting sleeve 7. A guide rod 95 is slidably fitted inside the clamping block 93 and is fixedly connected to the connecting sleeve 7. A second spring 96 is provided outside the guide rod 95. One end of the second spring 96 is fixedly connected to the clamping block 93, and the other end of the second spring 96 is fixedly connected to the connecting sleeve 7. By designing the second spring 96, the elastic force of the second spring 96 can act on the clamping block 93. By designing the connecting mechanism 9, it is convenient to remove the connecting sleeve 7 from the blade sleeve 1.

[0021] The specific implementation process of this utility model is as follows: In use, the blade 3 can be stored by sliding connection between the blade holder 2 and the connecting block 4 and the blade sleeve 1, making the blade 3 easy to carry and use. The connecting sleeve 7 can protect the outside of the blade sleeve 1, which can improve the portability and safety of the blade sleeve 1.

[0022] When it is necessary to disassemble the connecting sleeve 7, simply pull the connecting sleeve 7 downwards. The connecting sleeve 7 will cause the retaining ball 92 to move downwards. The retaining ball 92 will roll along the arc surface of the retaining groove 91. When the retaining ball 92 is squeezed, it will roll into the connecting sleeve 7. The retaining ball 92 will push the clamping block 93 to move. The clamping block 93 will squeeze the spring ball 94. At the same time, the clamping block 93 will slide along the guide rod 95 and squeeze the second spring 96. Finally, the retaining ball 92 can be separated from the retaining groove 91, and the connecting sleeve 7 can be removed from the blade sleeve 1. It is convenient to use.

[0023] When the blade 3 needs to be used, first disassemble the connecting sleeve 7, then pull the lever 83 upward. The lever 83 drives the limiting lever 82 to move upward, and the limiting lever 82 squeezes the first spring 84. At the same time, the limiting lever 82 will drive the magnetic block 85 to move upward, so that the magnetic block 85 attracts the magnet 86. Then, slide the blade holder 2 and the blade 3 out from the inside of the blade sleeve 1. The blade holder 2 will drive the connecting block 4 to slide along the connecting groove 10. Then push the lever 83 in the opposite direction to separate the magnetic block 85 from the magnet 86. At this time, under the elastic action of the first spring 84, a counter-pushing force will be given to the limiting lever 82, which can push the limiting lever 82 into the limiting groove 5 at the top of the connecting block 4. At this time, the blade holder 2 and the blade 3 can be used in a limited position, and the blade holder 2 and the blade 3 can also slide directly out from the inside of the blade sleeve 1, which is convenient for changing blades of different shapes.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
