[0028] Reference Figures 1-4 This utility model provides a technical solution: a gearbox control mechanism, including a coupling box 1, a control lever 2, and a control adjustment mechanism 4. The control lever 2 is installed in the inner cavity of the coupling box 1 and extends to the top of the coupling box 1. A control handle 3 is installed on the top of the control lever 2, which allows the control adjustment mechanism 4 to drive the control handle 3 to move upward when the control adjustment mechanism 4 is rotated, thereby facilitating the adjustment of the height of the control handle 3. This makes it easier to improve the operator's comfort and control feel.
[0029] Reference Figures 1-2In a preferred embodiment, an adjustment mechanism 4 is provided, comprising a threaded groove 41, a movable sleeve 42, and a rotating ring 43. The threaded groove 41 is formed on the surface of the control lever 2, the movable sleeve 42 is fitted onto the surface of the control lever 2 and is connected to the control handle 3, and the rotating ring 43 is threaded onto the surface of the control lever 2. The rotating ring 43 can be installed after the threaded groove 41 is formed, so that when the rotating ring 43 is rotated, it drives the movable sleeve 42 to move up or down, thereby adjusting the height of the control handle 3. A limit block 5 is installed on the top of the rotating ring 43, and a limit groove 6 is formed on the bottom of the movable sleeve 42. The limit groove 6 is annular and the limit block 5 slides in the limit groove 6. When the rotating ring 43 is rotated, it moves up or down, causing the limit block 5 to slide in the limit groove 6, thereby driving the movable sleeve 42 to move, thus facilitating the adjustment of the height of the control handle 3.
[0030] Reference Figures 1-3 In a preferred embodiment, a connecting block 7 is inserted into the top of the control lever 2, and the top of the control lever 2 is slidably connected to the connecting block 7 via a mounting ring. A pressing block 8 is movably mounted on the top of the control handle 3, and a mounting cylinder 9 is mounted on the bottom of the pressing block 8. A connecting rod 10 is mounted on the bottom of the mounting cylinder 9. The connecting rod 10 is connected to the connecting block 7, enabling the pressing block 8 to be installed on the mounting cylinder 9 after installation, so that the connecting rod 10 is installed in the mounting cylinder 9. The inner cavity of the connecting block 7 has a movable groove 15. A pressing rod 16 is mounted on the top of the inner cavity of the mounting cylinder 9. The pressing rod 16 passes through the connecting rod 10 and extends into the inner cavity of the movable groove 15. A first spring 17 is installed in the inner cavity of the mounting cylinder 9 and sleeved on the surface of the pressing rod 16. When the pressing block 8 is installed, the pressing block 8 can drive the pressing rod 16 to move through the mounting cylinder 9. The first spring 17 installed in the inner cavity of the mounting cylinder 9 can support the mounting cylinder 9, so that the mounting cylinder 9 can drive the pressing rod 16 and the pressing block 8 to return to their original position.
[0031] Reference Figures 1-4In a preferred embodiment, a fixed plate 11 is installed in the inner cavity of the operating handle 3, and a movable plate 12 is installed at the bottom of the fixed plate 11. A movable groove 13 is formed at the bottom of the fixed plate 11, and a movable block 14 is installed at the top of the movable plate 12. The movable block 14 slides in cooperation with the movable groove 13, so that the movable groove 13 is formed after the fixed plate 11 is installed, and the movable block 14 slides in cooperation with the movable groove 13, which facilitates the stable movement of the movable plate 12. A pressing plate 18 is installed at the bottom of the pressing rod 16, and the pressing plate 18 slides in the inner cavity of the movable groove 15. A movable plate 18 is installed at the top of the pressing plate 18. There is a plug-in block 19, and the top of the movable plate 12 is provided with a plug-in groove 20. The plug-in block 19 and the plug-in groove 20 are plugged into each other, so that when the extrusion plate 18 is extruded and moved downward, the plug-in block 19 is moved, thereby separating the plug-in block 19 from the plug-in groove 20. At the same time, a first tension spring 21 is installed on the left side of the movable plate 12, and the left end of the first tension spring 21 is connected to the inner cavity of the operating handle 3. After the plug-in block 19 is separated from the plug-in groove 20, the first tension spring 21 pulls the movable plate 12, which separates the movable plate 12 from the connecting block 7, thereby facilitating the downward adjustment of the operating handle 3.
[0032] Reference Figures 1-4 In a preferred embodiment, an extension plate 22 is installed on the left side of the movable plate 12, and the extension plate 22 extends to the left side of the operating handle 3. A connecting frame 23 is installed at the bottom of the extension plate 22, which can drive the extension plate 22 to move when the connecting frame 23 is moved to the right, so that the extension plate 22 can push the movable plate 12 and insert the movable plate 12 into the connecting block 7.
[0033] Specifically, the working process or working principle of this gearbox control mechanism is as follows: When adjusting the height of the control lever 3, the pressing block 8 is first pressed down, so that the pressing block 8 presses the pressing rod 16 through the mounting cylinder 9, causing the pressing rod 16 to move downward. This allows the pressing rod 16 to drive the insertion block 19 downward through the pressing plate 18, thereby separating the insertion block 19 from the insertion groove 20. After the insertion block 19 separates from the insertion groove 20, the first tension spring 21 can be pulled by the moving plate 12, causing the moving plate 12 to move and separate from the connecting block 7. Then, the rotating ring 43 is rotated, which allows the rotating ring 43 to drive the moving sleeve 42 upward or upward through the limiting block 5, thereby allowing the moving sleeve to move upward or upward. 42 drives the operating handle 3 to move, so as to adjust the height of the operating handle 3. After the height of the operating handle 3 is adjusted, the pressing block 8 is pressed down again and the connecting frame 23 is pushed, so that the connecting frame 23 drives the moving plate 12 to move through the extension plate 22, so that the moving plate 12 is inserted into the connecting block 7 and the insertion groove 20 is located at the top of the insertion block 19. Then the pressing block 8 is released, so that the first spring 17 supports the mounting cylinder 9, so that the mounting cylinder 9 drives the pressing rod 16 to move upward. When the pressing rod 16 moves upward, it drives the pressing plate 18 and the insertion block 19 to move, and then inserts the insertion block 19 into the insertion groove 20, so that the moving plate 12 limits the connection block 7.
