DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0026] like Figure 1-3As shown, a sapling protection net cover tie mouth structure includes: a support frame 10, including two semicircular tubes 11, two Z-shaped tubes 12, and a tube 13. The tube 13 and the semicircular tube 11 have an opening in the middle. The first end of the Z-shaped tube 12 is inserted into the middle opening of the semicircular tube 11 and can be movably connected. The second end is inserted into the opening of the tube 13 and is fixedly connected. The spacing between the lower ends of the two Z-shaped tubes 12 is greater than the spacing between the upper ends. Therefore, in a free state, the two Z-shaped tubes 1 2, the lower end of the rotary button 20 is slightly expanded outward to form an "eight"-shaped structure; the rotary button 20 includes an outer cover 21, an inner cover 22, an inner-toothed ratchet 23, a baffle 24, a pull ring 25, a pull rod 26, a pull ring outer cover 27, a rotating shaft 28 and a torsion spring 29, the outer cover 21 and the inner-toothed ratchet 23 are fixedly connected by a second key 231, the inner-toothed ratchet 23 and the pull rod outer cover 27 are fixedly connected by a third key 232, the inner-toothed ratchet 23 is arranged in the outer cover 21, and the baffle 24 is arranged In the inner cover 22, the outer cover 21 and the inner cover 22 are combined and placed on the round tube 13; the net bag 30 is put on the semicircular tube 11, and the inside is supported by the Z-shaped round tube 12; the ring formed by the semicircular tubes 11 below can support the opening of the net bag 30, making it more convenient to put the seedlings in without breaking the branches and leaves of the seedlings. The internal Z-shaped round tube 12 support can prevent the net bag 30 from fluttering in the wind and play a fixing role; the drawstring 40 has two sections The two sections of drawstrings 40, wherein the first drawstring 41 is connected and bypasses the first semicircular tube 111, extends out through the opening of the second semicircular tube 112, and is fixedly connected to the pull rod outer cover 27 through the second Z-shaped tube 122 and the left opening of the tube 13; the second drawstring 42 is connected and bypasses the second semicircular tube 112, passes through the opening of the first semicircular tube 111, and is fixedly connected to the other end of the pull rod outer cover 27 through the first Z-shaped tube 121 and the right opening of the tube 13. The two semicircular tubes 11 in the support frame 10 have different radius sizes. The two ports of the first semicircular tube 111 can be inserted into the port of the second semicircular tube 112. The diameter of the ring formed after the semicircular tubes 11 are meshed is larger than the diameter of the tube 13. A double ratchet 14 is set at the connection between the semicircular tube 11 and the Z-shaped tube 12. The first key 413 is fixedly connected to the semicircular tube 11. When the Z-shaped tube 12 rotates 90° clockwise, the inner ratchet 142 is locked, and the outer ratchet 141 drives the inner ratchet 142 to rotate clockwise together; when the Z-shaped tube 12 rotates 90° counterclockwise, the outer ratchet 141 is locked, and the inner ratchet 142 rotates counterclockwise. In this way, the double ratchet 14 can realize the switching between forward and reverse motion. The first end of the Z-shaped circular tube 12 is inserted into the middle opening of the semicircular tube 11 and can be movably connected. The first end of the Z-shaped circular tube 12 can rotate around the double ratchet 14, which is convenient for the staff to fold, collect and reuse. The second end is inserted into the opening of the circular tube 13 and is fixedly connected to carry the rotating button 20, so that the rotating button 20 is fixed and not easily moved by the wind or squeezed downward by its own gravity on the seedlings, thereby protecting the seedlings from being squeezed and damaged by the rotating button 20.

[0027] like Figure 4-6 As shown, the rotary button 20 includes an outer cover 21, an inner cover 22, an inner toothed ratchet 23, a baffle 24, a pull ring 25, a pull rod 26, a pull ring outer cover 27, a rotating shaft 28 and a torsion spring 29. The outer cover 21 is fixedly connected to the inner toothed ratchet 23 through a second key 231, and the inner toothed ratchet 23 is fixedly connected to the pull rod outer cover 27 through a third key 232. The inner toothed ratchet 23 is arranged in the outer cover 21, the baffle 24 is arranged in the inner cover 22, and the outer cover 21 and the inner cover 2 2 are combined and placed on the round tube 13; the two sections of drawstrings 40, wherein the first drawstring 41 is connected and bypassed around the first semicircular tube 111, passes through the opening of the second semicircular tube 112, passes through the second Z-shaped round tube 122 and is fixedly connected to the pull rod outer cover 27 with the left opening of the round tube 13, and the second drawstring 42 is connected and bypassed around the second semicircular tube 112, passes through the opening of the first semicircular tube 111, passes through the first Z-shaped round tube 121 and is fixedly connected to the right opening of the round tube 13 on the pull rod outer cover 27. At the other end of the rod cover 27, the baffle 24 is fixedly connected to the center of the inner tooth ratchet 23. After the rotary button is rotated 20, the drawstring 40 can be rotated around the pull ring cover 27 for collection. The baffle 24 can prevent the drawstring 40 from being wrapped around the pull ring cover 27 and not falling off. At this time, under the action of the drawstring 40, the first semicircular tube 111 and the second semicircular tube 112 are pulled inward to achieve the tightening function of the drawstring 40; the pull ring 25 is fixedly connected to the pull rod 26, and the pull rod 26 is below The fixed belt is provided with a square piece 261, and the square piece 261 is connected to the baffle plate 24 by a rotating shaft 28, and the rotating shaft 28 is provided with a torsion spring 29. When the pull ring 25 is pulled, the pull rod 26 moves upward. At this time, since the baffle plate 24 is blocked on the outside by the pull ring outer cover 27, the baffle plate 24 will rotate downward around the rotating shaft 28 to compress the torsion spring 29. When the baffle plate 24 and the pull rod 26 are in the same vertical direction, the drawstring 40 wrapped around the baffle plate 24 will fall off, thereby loosening the drawstring 40. The working principle of the sapling protection net cover is as follows: first, the sapling protection net cover cover structure is put on the sapling, the outer cover 21 of the rotary button 20 is adjusted, the outer cover 21 and the inner toothed ratchet 23 are fixedly connected by the second key 231, and the inner toothed ratchet and the pull rod outer cover 27 are fixedly connected by the third key 232. Under the action of the inner toothed ratchet 23, the draw rope 40 is wound around the pull rod outer cover 27. At this time, the draw rope 40 drives the first semicircular tube 111 and the second semicircular tube 112 to be relatively close to the draw rope. When the net bag 30 needs to be removed from the seedlings, the pull ring 25 is pulled, and the pull ring 25 drives the pull rod 26 to move upward. At this time, since the baffle 24 is blocked on the outside by the pull ring outer cover 27, the baffle 24 will rotate downward around the rotating shaft 28 and then compress the torsion spring 29. When the baffle 24 and the pull rod 26 are in the same vertical direction, the drawstring 40 wrapped around the baffle 24 will fall off, so that the drawstring 40 is relaxed.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
