[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, but the protection scope of the present invention is not limited by the embodiments.

[0019] like Figure 1 and Figure 3 As shown, the utility model is a pair of tweezers for inoculating tissue culture seedlings of fruit trees, which comprises a scissor handle 1 and a scissor handle 2, wherein the upper part of the scissor handle 1 is fixedly connected with a scissor blade 26, the upper part of the scissor handle 2 is fixedly connected with a scissor blade 15, the interiors of the scissor handle 1 and the scissor handle 2 are both threadedly connected with a rivet 4, the interior of the scissor handle 2 is provided with a groove 25, the interior of the groove 15 is fixedly connected with a fixing box 21, the interior of the fixing box 21 is slidably connected with a moving plate 18, one side of the moving plate 18 is fixedly connected with a pulling component, the pulling component is used to pull the moving plate 18 to move, the other side of the moving plate 18 is fixedly connected with an inserting rod 19, the outer side of the scissor handle 1 is fixedly connected with an inserting block 13, the inner part of the inserting block 13 A socket 14 is provided at the bottom, and an insertion rod 19 is slidably connected to the inside of the socket 14. Finger holes 3 are provided inside the scissors handle 1 and the scissors handle 2. Tweezers 23 are fixedly connected to the bottom of the scissors handle 1 and the scissors handle 2. The pulling assembly includes a pull rod 17, and the pull rod 17 is fixedly connected to the side of the moving plate 18 away from the insertion block 13. The other end of the pull rod 17 is fixedly connected to the handle 16. A return spring 20 is sleeved on the outside of the pull rod 17, one end of the return spring 20 is fixedly connected to the moving plate 18, and the other end of the return spring 20 is fixedly connected to the inside of the fixed box 21. The pull rod 17 and the insertion rod 19 are both slidably connected to the inside of the fixed box 21, and the handle 16 and the pull rod 17 are slidably connected to the inside of the groove 2 15.

[0020] After using the scissors, the user only needs to gently pull the handle 16. This action will drive the pull rod 17 to move, further squeezing the movable plate 18 toward the direction of the scissor handle 1. During this process, the return spring 20 will be compressed and store huge elastic potential energy. The return spring 20 is a highly elastic metal component that can generate a reverse thrust when under pressure. When the user inserts the plug block 13 outside the scissor handle 1 into the inside of the scissor handle 2, release the handle 16, and the return spring 20 will instantly release its stored energy, pushing the movable plate 18 to move in the opposite direction. The movable plate 18 will drive the plug rod 19 to insert into the socket 14 inside the plug block 13, thereby firmly fixing the two scissor handles together to prevent the scissors from accidentally opening during carrying or storage. The tweezers 23 can be used to clamp tiny plant tissues, such as buds or tender shoots of scion, for precise docking during grafting. During grafting or tissue culture, some tiny obstacles such as dead leaves, dead branches or excess plant tissues may be encountered, and they can be easily removed using tweezers 23.

[0021] like Figure 1 and Figure 2 As shown, a groove 9 is provided inside each of the scissors handle 1 and the scissors handle 2, a fixing block 10 is fixedly connected inside each of the two grooves 9, a protrusion 12 is slidably connected inside each of the two fixing blocks 10, a buffer spring 11 is provided inside each of the two fixing blocks 10, one end of the buffer spring 11 is fixedly connected inside the fixing block 10, and the other end of the buffer spring 11 is fixedly connected to the protrusion 12, an anti-slip pad 22 is provided on one side of the outside of the scissors handle 1 and the scissors handle 2, a connecting block 7 is fixedly connected to one side of the outside of the scissors handle 2, and a hanging ring 8 is fixedly connected to the other side of the connecting block 7.

[0022] When in use, the user only needs to put two fingers into the ingeniously designed finger holes 3 inside the scissors handle 1 and the scissors handle 2 respectively. The two scissors handles are provided with anti-skid pads 22, which are made of anti-skid material and can effectively enhance the friction between the fingers and the scissors. Even in a wet hand or sweaty environment, the user's grip stability can be ensured to prevent the scissors from accidentally slipping. During the shearing process of the scissor blades 1 5 and 6, the two uniquely designed protrusions 12 will squeeze each other. When the protrusions 12 are subjected to such pressure, they will move toward the inside of the fixed block 10. This process will also exert pressure on the built-in buffer spring 11. The buffer spring 11 will generate a reaction force when squeezed, thereby achieving a buffering effect, effectively absorbing the impact force generated during shearing, significantly reducing the vibration of the hand when using the scissors, and helping to protect the user's hand health. In addition, a connecting block 7 is fixedly connected to one side of the outer side of the scissors handle 2, and a hanging ring 8 is fixed to the other side of the connecting block 7. The hanging ring 8 is not only convenient for the user to hang the scissors on a workbench or a coat hook to save space, but also allows the scissors to be easily hung up when not in use, thereby avoiding potential safety hazards caused by randomly placing the scissors.

[0023] The working principle of the utility model is as follows: when using the scissors, the user puts two fingers into the finger holes 3 inside the scissor handle 1 and the scissor handle 2 respectively, and under the action of the anti-skid pad 22, the scissors can be held more stably. When using the scissor blade 1 5 and the scissor blade 2 6, the two protrusions 12 squeeze each other, and the protrusion 12 is squeezed and moves toward the inside of the fixed block 10. When the protrusion 12 moves, it squeezes the buffer spring 11, thereby achieving effective buffering of the scissors, reducing the vibration of the hand when using the scissors, and reducing the fatigue of the hand muscles after long-term use. When the scissors are used, the handle 16 is pulled first, so that the handle 16 drives the pull rod 17 to move, and the pull rod 17 moves When the handle 1 is moved, the movable plate 18 is driven to move, and the movable plate 18 is pressed against the reset spring 20 when it moves. Under the elasticity of the reset spring 20, the movable plate 18 drives the insertion rod 19 to move. Then, the insertion block 13 outside the scissors handle 1 is inserted into the inside of the scissors handle 2, and the handle 16 is released. Under the action of the reset spring 20, the movable plate 18 drives the insertion rod 19 to be restored and inserted into the insertion hole 14 inside the insertion block 13, thereby fixing the scissors handle 1 and the scissors handle 2, thereby facilitating the engagement of the scissors handle 1 and the scissors handle 2, preventing the scissors from being accidentally opened during use or carrying, preventing the scissors blade from contacting other objects during carrying, reducing the risk of injury, and improving the safety of use.
