[0028] Reference Figure 1-4 This utility model provides an embodiment of a multi-functional operating handle for a micro-tiller, comprising a handle body 1, a connecting block A4 connected to one end of the handle body 1, a connecting block B5 connected to one end of the connecting block A4, and a mounting bracket 2 connected to one end of the connecting block B5. The mounting bracket 2 has a threaded groove 6 and a mounting slot 7 on its surface. A fixing pin 8 is connected to the upper end of the connecting block A4. A handle 9 and a rubber sleeve 10 are connected to the other end of the handle body 1. A hook 3 is provided at the bottom. A fixed column 11 is connected to the bottom of the handrail body 1. A movable column 12 is installed below the fixed column 11. A self-locking caster wheel 13 is connected to the bottom of the movable column 12. A pin hole 14 and a movable pin 15 are provided inside the fixed column 11 and the movable column 12. A protrusion 17 and a pin hole 18 are connected to one end of the connecting block B5. A support spring 16 is installed inside the movable column 12. A clamping block 19 and a damping spring 20 are provided inside the rubber sleeve 10.
[0029] In this invention, the connecting block A4 is integrally connected to one end of the handrail frame body 1, and the connecting block B5 is integrally connected to one end of the mounting bracket 2. Connecting block A4 and connecting block B5 are of the same size. A protruding block 17 is fixedly connected to one end of connecting block B5, and the size of the protruding block 17 is smaller than that of connecting block B5. A pin hole 18 is formed inside the protruding block 17, which is inserted into the connecting block A4. A fixing pin 8 passes through and connects connecting block A4, protruding block 17, and pin hole 18. There are several fixing pins 8. This design makes the connection between connecting block A4 and connecting block B5 more stable and less prone to loosening. Simultaneously, because the size of the protruding block 17 is smaller than that of connecting block B5, and the protruding block 17 is inserted into the connecting block A4, this design increases the tightness of the connection and improves the overall structural stability. The number of fixing pins 8 is several, which further enhances the firmness of the connection, making the connection between the main body 1 of the handrail frame and the mounting frame 2 more reliable, and able to withstand greater external forces and impacts, thereby extending the service life of the handrail frame and improving the operational stability and safety of the micro-tiller.
[0030] Furthermore, the mounting bracket 2 is fixedly connected to one end of the handrail frame body 1 by a fixing pin 8. Several threaded grooves 6 are formed on the surface of the mounting bracket 2, and the mounting slot 7 is located at the center of the mounting bracket 2. This design makes the connection between the mounting bracket 2 and the handrail frame body 1 more secure and less prone to detachment. The number of threaded grooves 6 allows users to install different accessories or tools as needed, improving the multifunctionality and practicality of the handrail frame. The mounting slot 7 provides users with a convenient installation space, making the installation of accessories or tools simpler and faster, further enhancing the user's operating experience.
[0031] Furthermore, the handle 9 is fixedly connected to one end of the armrest frame body 1, and there are two handles 9. The rubber sleeve 10 is fixedly connected to the outside of the handle 9, the clamping block 19 is fixedly connected to the inner wall of the rubber sleeve 10, and the damping spring 20 is fixedly connected to one end of the clamping block 19. There are several clamping blocks 19. This design allows the user to grip the handle 9 more comfortably during operation, improving the convenience and stability of operation. The rubber sleeve 10 not only increases the friction coefficient of the handle 9 to prevent hand slippage but also improves the user's grip comfort. The cooperation of the clamping block 19 and the damping spring 20 ensures that the user's hand remains comfortable during long-term operation of the micro-tiller, reducing hand fatigue.
[0032] Specifically, the design of multiple clamping blocks 19 further enhances the structural stability of the handle 9, making the entire handrail frame more durable. Overall, this design not only improves the user experience but also enhances the functionality and practicality of the handrail frame.
[0033] Furthermore, two fixed posts 11 are fixedly connected to the bottom of the handrail body 1. A movable post 12 is movably connected below the fixed posts 11, and the movable post 12 is larger than the fixed post 11. Several pin holes 14 are formed inside the fixed posts 11 and the movable post 12. A movable pin 15 is movably connected inside the pin holes 14. This design allows the height of the handrail to be flexibly adjusted according to the height and operating needs of different users. The movable post 12 can slide below the fixed posts 11. By adjusting the position of the movable pin 15 in the pin holes 14, the movable post 12 can be fixed, thus achieving fine-tuning of the handrail height. This height-adjustable design not only meets the needs of different users but also improves operational flexibility and adaptability.
[0034] Furthermore, the self-locking casters 13 are rotatably connected to the bottom of the movable column 12. There are two self-locking casters 13. The hook 3 is fixedly connected to the bottom of the handrail body 1. The top of the support spring 16 is fixedly connected to the fixed column 11, and the bottom of the support spring 16 is fixedly connected to the movable column 12. This design further enhances the functionality and user experience of the handrail. The introduction of the self-locking casters 13 allows the handrail to move and turn easily, facilitating flexible switching between different work areas. Simultaneously, the self-locking function ensures that the handrail can be stably stopped in a designated position when needed, preventing accidental slippage and improving operational safety.
[0035] Specifically, the hook 3 provides users with a convenient hanging point for storing tools or other small items, making operation more convenient and efficient. Furthermore, the addition of the support spring 16 not only acts as a buffer, reducing vibration during movement, but also enhances the overall stability of the handrail. When adjusting the handrail height, the support spring 16 assists in the smooth sliding of the movable column 12, making the adjustment process smoother and further improving the user experience.
[0036] Working principle and usage process: When in use, the operator can push the main body 1 of the handrail frame through the handle 9 to move it. The rubber sleeve 10 increases the comfort of the operator's hands. At the same time, the combination of the clamping block 19 and the damping spring 20 can achieve the function of shock absorption and buffering.
[0037] During installation, the operator can rotate the movable pin 15 to move it out of the pin hole 14, thereby adjusting the movable column 12 up and down to meet the needs of operators of different heights. After adjustment, the movable pin 15 is rotated back into the corresponding pin hole 14 to fix the movable column 12.
[0038] When it is necessary to fix the handrail frame body 1, the operator can rotate the self-locking caster 13 to activate its internal self-locking mechanism, thereby fixing the handrail frame body 1 and preventing it from moving. The hook 3 makes it convenient for the operator to hang items. The support spring 16 can buffer the movable column 12, preventing the movable column 12 from colliding with the fixed column 11 during movement, thus increasing the service life of the handrail frame body 1.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
