[0002] Cypress grafting is a common plant propagation technique used to combine the excellent varieties of cypress with the favorable characteristics of another cypress to obtain better growth, disease resistance and other characteristics. When grafting, it is usually necessary to use a grafting device to fix the Thuja plicata.

[0003] As disclosed in a tree grafting auxiliary device with the authorization announcement number CN219182161U, it includes a first fixing ring and a third fixing ring. A second fixing ring is provided on one side of the first fixing ring, and a fourth fixing ring is provided on one side of the third fixing ring. A fixing mechanism is fixedly connected to the outside of the first fixing ring. The fixing mechanism includes upper fixing seats on both sides, and the two upper fixing seats are respectively fixed on the outside of the first fixing ring and the second fixing ring. After adopting the above technical solution, the beneficial effect of the utility model is: it can meet the grafting of branches and trunks at different angles, and can also adjust the fixing length, making the device applicable and facilitating the replacement of tree grafting.

[0004] Although the above patent can meet the grafting of branches and trunks at different angles and can also adjust the fixing length, it uses a bolt assembly for fixing, making the operation more cumbersome during grafting. And when fixing, since the two semi-circular fixing rings cannot rotate relatively at a horizontal angle, multiple people are needed to assist in the operation during fixing. Therefore, when using the above device to batch graft Thuja plicata, the efficiency is low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for Thuja plicata grafting to solve the problems put forward in the above background technique.

Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-5 shown, a technical solution provided by the present utility model:

[0027] A device for cypress grafting includes a threaded barrel 1. Two fixing members 2 are movably installed inside the threaded barrel 1 through a rotating shaft. One ends of the outer sides of the two fixing members 2 are both provided with clamping jaws 3. A tightening mechanism is arranged between the outside of the threaded barrel 1 and the clamping jaws 3. The tightening mechanism includes a movable ring 5. The movable ring 5 is threadedly connected to the outside of the threaded barrel 1. A first retaining ring 6 is arranged on the outer wall of one end of the threaded barrel 1 away from the clamping jaws 3. Further, convex blocks 7 are arranged on the outer sides of one ends of the two clamping jaws 3 close to the threaded barrel 1. Inner grooves 16 are arranged on the inner walls of one ends of the two clamping jaws 3 close to the threaded barrel 1. A spring 17 is arranged between the two inner grooves 16;

[0028] In this embodiment, when fixing, the two clamping jaws 3 are clamped on the cypress tree branches for grafting, and then the movable ring 5 outside the threaded barrel 1 is rotated. When the movable ring 5 rotates along the outside of the threaded barrel 1, it moves towards the side of the clamping jaws 3 and pushes the convex blocks 7 on the outside of the two clamping jaws 3. When the convex blocks 7 are pushed, they move outwards and drive the clamping jaws 3 to clamp the cypress tree branches. In this way, during fixing, it can be operated by one person, and the operation is simple and faster.

[0029] As Figure 1 and Figure 4As shown in the figure, there is a connecting rod 4. The connecting rod 4 is arranged outside one end of the threaded cylinder 1 away from the clamping jaw 3. An adjusting mechanism is vertically arranged at the other end of the connecting rod 4. The adjusting mechanism includes a fixed block 8. A screw rod 9 is movably installed in the middle of the fixed block 8. The bottom end of the screw rod 9 passes through the fixed block 8 and is fixedly installed with a knob 10. A movable sleeve 11 is movably installed outside the screw rod 9. A clamp 12 is arranged outside one side of the movable sleeve 11. The adjusting mechanism further includes a first connecting rod 13. The first connecting rod 13 is movably installed at one end of the movable sleeve 11 away from the clamp 12. A second connecting rod 14 is arranged at one end of the fixed block 8 close to the first connecting rod 13. The same-direction ends of the second connecting rod 14 and the first connecting rod 13 are movably connected through a rotating shaft. A second retaining ring 15 is arranged outside the top end of the screw rod 9;

[0030] In this embodiment, after the device is fixed, turn the knob 10 below the fixed block 8. After the knob 10 rotates, it drives the screw rod 9 to rotate. When the screw rod 9 rotates, since the movable sleeve 11 and the outside of the fixed block 8 are movably connected through the first connecting rod 13 and the second connecting rod 14, the screw rod 9 can drive the movable sleeve 11 to move up and down linearly until the clamp 12 on the other side of the movable sleeve 11 moves to the specified height and then stops. Then insert the cypress seedlings to be grafted into the clamp 12 for fixation. In this way, during grafting, it is convenient to adjust the height, and the adjustment method is more convenient and practical.

[0031] Working principle: When fixing, clamp the two clamping jaws 3 on the cypress tree branches for grafting. Then rotate the movable ring 5 outside the threaded cylinder 1. When the movable ring 5 rotates along the outside of the threaded cylinder 1, it moves towards one side of the clamping jaw 3 and pushes the convex blocks 7 outside the two clamping jaws 3. When the convex blocks 7 are pushed, they move outward and drive the clamping jaws 3 to clamp the cypress tree branches. After the device is fixed, turn the knob 10 below the fixed block 8. After the knob 10 rotates, it drives the screw rod 9 to rotate. When the screw rod 9 rotates, since the movable sleeve 11 and the outside of the fixed block 8 are movably connected through the first connecting rod 13 and the second connecting rod 14, the screw rod 9 can drive the movable sleeve 11 to move up and down linearly until the clamp 12 on the other side of the movable sleeve 11 moves to the specified height and then stops. Then insert the cypress seedlings to be grafted into the clamp 12 for fixation.
