DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1-5 As shown, a grafting knife for forestry fruit cultivation includes a shell body 1, a mounting plate 2 is fixedly connected to the front side of the shell body 1, the function of the mounting plate 2 is to limit the components inside it, a push rod 4 is slidably connected inside the mounting plate 2, a blocking block 5 is fixedly connected to the front side of the push rod 4, and a first pressure spring 6 is fixedly connected to the right side of the blocking block 5. The blocking block 5 is driven to slide by pushing the push rod 4, and the first pressure spring 6 is squeezed, and the first pressure spring 6 is reset by the elastic force generated by the squeezing of the first pressure spring 6, so that the push rod 4 is more convenient to use. A cover plate 7 is rotatably connected to the left side of the shell body 1, and the function of the cover plate 7 is to cover the grafting film roll. A fixing component is arranged inside the cover plate 7, and a fixing component is arranged inside the cover plate 7. The assembly is convenient for fixing the cover plate 7. A plurality of placement grooves 12 are provided on the left side of the cover plate 7. The placement grooves 12 are provided to facilitate holding the cover plate 7. A blade 11 is slidably connected to the front side of the shell 1. The function of the blade 11 is to graft forestry fruit tree cultivation. A connecting plate 13 is fixedly connected to the rear side of the blade 11. The connecting plate 13 is provided with an adjustment assembly. Two brushes 21 are provided inside the mounting plate 2. The brush 21 fits the blade 11. By arranging the brush 21 inside the mounting plate 2, when the blade 11 is stored after use, the surface of the blade 11 is cleaned by the brush 21 to prevent the impurities remaining in the blade 11 from contaminating the forestry fruit when it is used next time.

[0032] The fixing assembly comprises a clamping rod 8 , the outer side of the clamping rod 8 is slidably connected to the front side of the cover plate 7 , the rear side of the clamping rod 8 is fixedly connected to a limiting block 9 , and the rear side of the limiting block 9 is fixedly connected to a second pressure spring 10 .

[0033] When the card rod 8 slides, it will drive the limit block 9 to slide and squeeze the second pressure spring 10. When the second pressure spring 10 is squeezed, it will reset, thereby pushing the limit block 9 to slide and driving the card rod 8 to slide, and further fixing the cover plate 7 through the card rod 8.

[0034] The clamping rod 8 passes through the mounting plate 2 and engages with the push rod 4. The side of the first pressure spring 6 away from the blocking block 5 is fixedly connected to the inner wall of the mounting plate 2. The side of the second pressure spring 10 away from the limiting block 9 is fixedly connected to the inner wall of the cover plate 7.

[0035] By engaging the locking rod 8 and the push rod 4, the cover plate 7 can be effectively fixed. By fixing the first pressure spring 6 and the second pressure spring 10, the damage to the first pressure spring 6 and the second pressure spring 10 during use due to not being fixed can be reduced, thereby increasing the service life of the device.

[0036] A groove 3 is provided on the left side of the mounting plate 2 , and the front side of the clamping rod 8 is slidably connected inside the groove 3 .

[0037] By providing the groove 3, the latch rod 8 can contact the inner wall of the groove 3 when the cover plate 7 rotates, thereby preventing the latch rod 8 from being unable to slide into the inside of the cover plate 7 when the cover plate 7 rotates, thereby preventing resistance from being generated and interfering with the rotation of the cover plate 7.

[0038] The adjustment assembly includes a hexagon socket bolt 14, the outer side of the hexagon socket bolt 14 is threadedly connected to the middle of the connecting plate 13, a gasket 15 is sleeved on the outer side of the hexagon socket bolt 14, a nut 16 is threadedly connected to the bottom of the hexagon socket bolt 14, a slider 17 is fixedly connected to the bottom of the nut 16, and the left and right sides of the slider 17 are fixedly connected to limit plates 18.

[0039] By rotating the hexagon socket bolt 14 to move it upward, the pressure of the hexagon socket bolt 14 on the gasket 15 can be reduced, and the nut 16 can be moved to adjust the length of the nut 16. When the blade 11 is damaged, the hexagon socket bolt 14 can be disengaged from the nut 16 by rotating the hexagon socket bolt 14, and then the blade 11 can be taken out and replaced.

[0040] Two first sliding grooves 19 are formed on the inner wall of the housing 1 . The outer side of the limiting plate 18 is slidably connected to the inside of the first sliding groove 19 , and the outer side of the sliding block 17 is slidably connected to the inner wall of the housing 1 .

[0041] By opening two first slide grooves 19 on the inner wall of the shell 1 and sliding the limit plate 18 inside the first slide groove 19, the blade 11 can be moved more conveniently when the length of the blade 11 is adjusted, and when the blade 11 is replaced, the nut 16 will not be separated from the shell 1, making the device unusable.

[0042] A second slide groove 20 is provided on the upper side of the housing 1 , and the outer side of the hexagon socket bolt 14 is slidably connected to the inside of the second slide groove 20 . The diameter of the gasket 15 is larger than the diameter of the second slide groove 20 .

[0043] The second slide groove 20 is provided to facilitate the sliding of the hexagon socket bolt 14, and the diameter of the gasket 15 is set to be larger than the diameter of the second slide groove 20, so that the hexagon socket bolt 14 will not fall into the second slide groove 20 when the gasket 15 is squeezed, and the blade 11 cannot be fixed through the contact between the second slide groove 20 and the shell 1.

[0044] It should be noted that the utility model is a grafting knife for forestry fruit cultivation. First, the hexagon socket bolt 14 is rotated to move the hexagon socket bolt 14 upward. The upward movement of the hexagon socket bolt 14 reduces the squeezing of the gasket 15. At this time, the length of the blade 11 can be adjusted so that the blade 11 can better graft forestry fruit cultivation. After the blade 11 is adjusted, the hexagon socket bolt 14 is reversed to squeeze the gasket 15 and threadedly connected with the nut 16 until the hexagon socket bolt 14 cannot be rotated, thereby fixing the blade 11. When the blade 11 is damaged and needs to be replaced, the hexagon socket bolt 14 can be rotated and taken out to release the fixation of the hexagon socket bolt 14 to the blade 11, and the blade 11 can be replaced. When the film roll is grafted when it is in use and not needed, the grafting can be removed by rotating the cover plate 7. The grafting film roll is blocked. When the cover plate 7 rotates, the clamping rod 8 will contact the inner wall of the groove 3, causing the clamping rod 8 to slide and drive the limit block 9 to slide, squeezing the second pressure spring 10. When the clamping rod 8 slides to the specified position, the second pressure spring 10 will be reset due to the squeezing, and then push the limit block 9 to slide, and push the clamping rod 8 to slide, so that the clamping rod 8 is engaged with the push rod 4 to fix the cover plate 7. When the grafting film roll is needed, the push rod 4 is pressed to slide, and the sliding of the push rod 4 drives the blocking block 5 to slide and squeezes the first pressure spring 6. At the same time, the sliding of the push rod 4 will also squeeze the clamping rod 8 due to the action of the outer wall. When the clamping rod 8 is squeezed to the inner wall of the groove 3, the cover plate 7 can be rotated, so that the grafting film roll can be taken out for use. The whole device has a simple structure and is suitable for use in forestry fruit cultivation.
