[0002] Lawn mowers are commonly used and essential tools in lawn maintenance. Titanium-plated blades, as the core component directly performing the cutting task, are made using a titanium plating process, resulting in high hardness and wear resistance. Their sharp blades can easily cut various grass stems, helping to efficiently complete lawn mowing tasks. Due to frequent contact with the lawn, they wear out quickly and need to be replaced regularly to ensure the best mowing results. Replacing lawn mower blades primarily relies on manual operation.
[0003] The traditional replacement process for titanium-coated blades mainly involves operators wearing gloves holding the blade to position it and prevent it from loosening, while simultaneously tightening the bolts with an electric screwdriver to complete the installation. This traditional replacement method has significant drawbacks. The blades themselves are very sharp, and during manual positioning, even a slight mistake can easily cut the operator's hand, posing a serious threat to their personal safety. Manual positioning also makes it difficult to accurately control the blade's position, resulting in insufficient installation precision. Therefore, a titanium-coated blade is proposed. Summary of the Invention

[0026] Example
[0027] In existing technologies, the replacement process for titanium-plated blades mainly involves an operator wearing gloves holding the blade to position it and prevent it from loosening, while simultaneously tightening the bolts with an electric screwdriver to complete the installation. This traditional replacement method has significant drawbacks. The blade itself is very sharp, and during manual positioning, even a slight mistake can easily cut the operator's hand, posing a serious threat to the operator's personal safety. Manual positioning also makes it difficult to accurately control the blade's position, resulting in insufficient installation precision.
[0028] Please refer to Figures 1-6. This utility model provides a technical solution: a titanium-plated blade, including two blades 1, a straight cylinder 2, and a housing 3. The two blades 1 are fixedly connected to both sides of the straight cylinder 2. An adjustment component 6 is provided on the outer side of the straight cylinder 2, and a positioning component 5 is provided inside the straight cylinder 2. The straight cylinder 2 is connected to the housing 3 through the positioning component 5. A cylinder body 4 is fixedly connected to the inner bottom wall of the housing 3. A washer 7 and a cover plate 8 are sequentially sleeved through the top of the cylinder body 4 through the straight cylinder 2. Bolts are threaded inside the straight cylinder 2, and the straight cylinder 2 with blades 1, the washer 7, and the cover plate 8 are sequentially fixed inside the housing 3 by the bolts.
[0029] The positioning component 5 includes two movable rods 51. One end of each movable rod 51 is movably inserted into the straight cylinder 2 and fixedly connected to a first spring plate 53. The other end of the movable rod 51, away from the first spring plate 53, passes through the straight cylinder 2 and is fixedly connected to a second spring plate 54. A spring 52 is sleeved on the outer side of each movable rod 51. A through hole 55, adapted to the movable rod 51, is opened on the outer side of the straight cylinder 2. The movable rod 51 moves through the through hole 55. The spring 52 is located between the straight cylinder 2 and the second spring plate 54. When the spring 52 loses its external spring plate 54, it will move through the through hole 55. When the force is applied, the second spring 54 is pushed to reset. The inner wall of the straight cylinder 2 is provided with a groove 56 that matches the first spring 53. The groove 56 is connected to the through hole 55. When the second spring 54 is reset, the first spring 53 is pulled back into the groove 56 by the moving rod 51, so that the straight cylinder 2 can quickly detach from the cylinder 4. Two slots 57 that match the first spring 53 are provided on the outer side of the cylinder 4. The first spring 53 is movably inserted into the slot 57.
[0030] The adjusting assembly 6 includes a first sleeve 61 and a second sleeve 66. A conical cover 62 is integrally formed between the first sleeve 61 and the second sleeve 66. Two sliders 64 are fixedly connected to the inner wall of the first sleeve 61. Two spiral grooves 65 adapted to the sliders 64 are opened on the outer wall of the straight cylinder 2. When the sliders 64 move inside the spiral grooves 65, they drive the first sleeve 61 to rotate and move downward around the outer side of the straight cylinder 2. Both the first sleeve 61 and the second sleeve 66 are movably sleeved on the outer side of the straight cylinder 2. The inner wall of the conical cover 62 is connected to the first sleeve 61. The outer sides of the two springs 54 abut against each other, and the inner wall of the second sleeve 66 is fixedly connected with a sealing ring 63. The inner wall of the sealing ring 63 abuts tightly against the outer wall of the straight cylinder 2. The sealing ring 63 is to prevent impurities from entering the conical cover 62 along the second sleeve 66 and blocking the conical cover 62. The inner bottom wall of the straight cylinder 2 is provided with a conical notch 58. When the straight cylinder 2 is sleeved on the outside of the cylinder 4, the conical notch 58 plays a guiding role. The outer side of the first sleeve 61 is provided with anti-slip texture, which increases the friction between the hand and the first sleeve 61.
[0031] The working principle or structural principle is as follows: Hold the straight cylinder 2 containing the blade 1 and place it on the outside of the inner cylinder 4 of the housing 3. After the cylinder 4 passes through the straight cylinder 2, hold the first sleeve 61 on the outside of the straight cylinder 2 and rotate it. The first sleeve 61 drives the conical cover 62 to rotate downward. The slider 64 slides in the spiral groove 65. As the conical cover 62 moves downward, it pushes the two second spring pieces 54 inside to move closer to each other. The second spring pieces 54 drive the two first spring pieces 53 to move closer to each other through the moving rod 51. The two first spring pieces 53 disengage from the groove 56 and insert into the slots 57 on both sides of the cylinder 4. Because the first spring pieces 53 and the second spring pieces 54 are elastic, they can adapt to slots 57 of different sizes, thereby quickly positioning the straight cylinder 2 at the center position of the housing 3. Then, the washer 7 and the cover plate 8 are successively placed on the outside of the cylinder 4. The straight cylinder 2, washer 7 and cover plate 8 are fixed to the outside of the cylinder 4 with bolts, and the blade 1 is quickly installed inside the housing 3. When the first sleeve 61 rotates to its lowest position, as shown in Figure 1, the spiral groove 65 is wrapped by the first sleeve 61 and will not be exposed to the outside, and will not be blocked by impurities. The sealing ring 63 is also to prevent impurities from entering the conical cover 62 and blocking the conical cover 62.
[0032] In summary, by holding the straight cylinder 2 and placing it on the outside of the cylinder body 4, with the cylinder body 4 passing through the straight cylinder 2, and then rotating the first sleeve 61, the first sleeve 61 causes the conical cover 62 to rotate downwards, pushing the two internal second spring pieces 54 to move closer to each other. The second spring pieces 54, through the moving rod 51, cause the two first spring pieces 53 to move closer to each other and insert into the slots 57 on both sides of the cylinder body 4, quickly positioning the straight cylinder 2 at the center of the shell 3. Bolts then fix the straight cylinder 2, washer 7, and cover plate 8 to the outside of the cylinder body 4, and the blade 1 is quickly installed inside the shell 3. This rapid positioning is achieved through the positioning component 5. Compared to the traditional handheld blade 1 positioning and installation method, this method is safer, faster, and more precise, improving the installation accuracy of the blade 1. The spring 52, first spring pieces 53, second spring pieces 54, sealing ring 63, and washer 7 require regular inspection, maintenance, and replacement.
