[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-8 This utility model provides a technical solution:

[0030] A type of landscaping trimmer with a non-slip handle includes a blade 1 and a handle assembly 2. A handle assembly 3 is mounted on the outside of the handle assembly 2. The handle assembly 2 includes a handle body 21. An air groove 22 is formed on the inner side of the handle body 21. Guide grooves 23 are formed at both the upper and lower ends of the handle body 21. A threaded hole 24 is formed at the right end of the handle body 21. A double-column groove 25 and a connecting air port 26 are formed on the inner side of the handle body 21. A spring 27 is fixedly connected to one side of the double-column groove 25. A plug rod 28 is fixedly connected to one end of the spring 27. A first sealing ring 29 is fixedly connected to the outside of the plug rod 28. The handle assembly 3 includes a rubber sleeve 31. A handle body 32 is fixedly connected to the inner side of the rubber sleeve 31. A slot 38 is formed on the inner side of the handle body 32. A rail 39 is fixedly connected to the inner side of the handle body 32. The inner side of the air groove 22 fits against the outer side of the second sealing ring 37. An outward expansion post 36 is inserted into the air groove 22.

[0031] As a further implementation of this solution, the threaded hole 24 is connected to the air groove 22, and the double-column groove 25 is formed by two cylinders of different diameters. The double-column groove 25 is connected to the connecting air port 26, and the connecting air port 26 is connected to the air groove 22. Through the above settings, the internal gas flow can be effectively guided, and the functions of rapid sealing and reset can be realized, thereby improving the stability and reliability of the device and simplifying the installation process.

[0032] As a further implementation of this solution, the outer side of the first sealing ring 29 fits against the inner side of the double-column groove 25, and the shape of the insertion rod 28 is two cylinders of different diameters. The insertion rod 28 is inserted into the inner side of the slot 38. Through the above arrangement, after being subjected to air thrust, the insertion rod 28 is inserted into the inside of the slot 38, thereby realizing the function of limiting the position between the handle body 32 and the knife handle body 21, and improving the stability during use.

[0033] As a further implementation of this solution, the outer side of the expansion column 36 is rotatably connected to the inner side of the limiting shaft hole 35. The limiting shaft hole 35 is opened at the left end of the external threaded rotating rod 34. The right side of the external threaded rotating rod 34 is fixedly connected to the baffle 33. The outer side of the external threaded rotating rod 34 is provided with threads. The external threaded rotating rod 34 is installed inside the threaded hole 24 by a threaded screw. The left side of the baffle 33 fits against the right side of the tool holder body 21. Through the above settings, the friction between the parts is reduced, the efficiency of installation and disassembly is improved, and the replacement and maintenance of the handle is facilitated, thus reducing the cost of use.

[0034] As a further implementation of this solution, the limiting shaft hole 35 penetrates the left end of the external threaded rotating rod 34. The shape of the outer expansion column 36 is a cylinder with three different diameters. The opening diameter of the threaded hole 24 is larger than the opening diameter of the air groove 22. With the above settings, when the outer expansion column 36 is installed inside the air groove 22, a gap is left between the external threaded rotating rod 34 and the threaded hole 24, avoiding friction with the threaded hole 24 that could cause the second sealing ring 37 to fail to seal. The rail 39 slides on the inner side of the guide groove 23. The number of rails 39 is the same as the number of guide grooves 23. The left side of the handle body 32 fits against the left side of the guide groove 23. With the above settings, precise alignment and stable connection between components are ensured, improving the assembly accuracy and reliability of the device. At the same time, it prevents the handle body 32 from twisting with the tool holder body 21, ensuring safety during use.

[0035] Workflow: During installation, align the rail 39 fixed to the handle body 32 with the guide groove 23. Place the handle body 32 onto the outside of the tool holder body 21, allowing the rail 39 to slide on the outside of the guide groove 23. When the left side of the handle body 32 is in contact with the left side of the guide groove 23, the double-column groove 25 and the slot 38 are vertically aligned. Then, hold the stop plate 33 and align the outward-expanding post 36 with the inside of the air groove 22. The diameter of the outward-expanding post 36 is smaller than the diameter of the threaded hole 24 to prevent secondary... Friction between the sealing ring 37 and the threaded hole 24 causes the second sealing ring 37 to fail. When the outward expanding post 36 moves into the air groove 22, it pushes the gas inside the air groove 22. At this time, the gas inside the air groove 22 can squeeze the insert rod 28, causing the insert rod 28 to move outward from the tool holder body 21. The first sealing ring 29 seals the insert rod 28 and the tool holder body 21. When the insert rod 28 moves, it squeezes the spring 27. The elastic force of the spring 27 can restore the insert rod 28. Positioned inside the double-column groove 25, one end of the insertion rod 28 slides into the slot 38. Through the action of the insertion rod 28 and the handle body 32, the stability of the connection between the handle body 32 and the knife handle body 21 can be improved, preventing the external threaded rod 34 from loosening due to left and right movement of the handle body 32, thus improving safety during use. After the external threaded rod 34 is in contact with the threaded hole 24, the external threaded rod 34 is rotated by the baffle 33, so that the external threaded rod 34 is spirally installed into the inside of the threaded hole 24. Through the setting of the limiting shaft hole 35 and the outer expansion post 36, the friction between the second sealing ring 37 and the knife handle body 21 can be reduced when the baffle 33 is rotated. At this time, the installation is completed. This installed device avoids the traditional structure where the handle and knife handle are integrated, making it convenient to replace the rubber sleeve 31 and the handle body 32 later. At the same time, this device can prevent the handle from falling off the knife handle due to insufficient friction caused by aging or wear after long-term use, ensuring the safety of the operator.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
