[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-3 As shown, this utility model is a dual-axis multi-functional operating lever, including a handle housing assembly 10, which includes a left housing 15 and a right housing 16, which are fixedly connected by bolts. An operating panel assembly 11 is embedded in the top of both the left and right housings, and a control switch 12 is embedded in their rear ends. A base 13 is also included, with a main operating lever 14 positioned between the base 13 and the handle housing assembly 10. The bottom ends of the left and right housings 15 and 16 are movably engaged with the main operating lever 14. The handle housing assembly 10, as a core supporting structure, provides physical support for human-machine interaction and protects internal precision components. The separate design of the left and right housings 15 and 16 facilitates assembly and maintenance. The base 13 provides a fixed foundation for the equipment and houses a built-in signal processing module. The control switch 12 is typically an emergency stop or main power switch, with a rear-mounted layout to prevent accidental activation. The operating panel assembly 11 integrates secondary control functions for easy operation.

[0027] It is worth noting that the base 13 and the main operating lever 14 are the main control inputs for the operating lever. The operating levers of the base 13 and the main operating lever 14 in the prior art (announcement number: CN222653321U) have been disclosed, and will not be described in detail here.

[0028] like Figure 4As shown, the control panel assembly 11 includes a control panel body 17, function buttons 19, and a second shaft 18 operating component. The control panel body 17 is snapped between the left outer shell 15 and the right outer shell 16. A sealing strip is fitted onto the outer circumferential surface of the control panel body 17. Multiple sets of function buttons 19 are embedded in one side of the top of the control panel body 17. By fitting a sealing strip onto the outer circumferential surface of the control panel body 17, the environmental adaptability of the device is improved, making it suitable for humid and dusty environments. The centralized layout of the function buttons 19 reduces blind spots and improves human-machine interaction efficiency.

[0029] like Figure 5 As shown, the second shaft 18 operating assembly includes a second shaft 18 and an operating box 21. A mounting groove is provided through the top of the operating panel body 17, and a limit frame 20 is fixedly installed within the mounting groove. The limit frame 20 constrains the physical travel of the second shaft 18 to prevent overload. The second shaft 18 is located above the limit frame 20, and its bottom end movably passes through the limit frame 20 and is fixedly connected to the moving block 25. This direct connection between the second shaft 18 and the moving block 25 reduces transmission backlash and improves control accuracy.

[0030] like Figure 6 As shown, the operating box 21 contains a control unit 22 and a potentiometer 23. A gear 24 is fixedly connected to the top of the potentiometer 23 for adjustment and rotation. The control unit 22 includes a moving block 25, a connecting block 28, and a rack 29. The rack 29 meshes with the gear 24. A fixing rod 26 is fixedly installed inside the operating box 21, passing through the moving block 25. Two sets of compression springs 27 are sleeved on the outer wall of the fixing rod 26, located on both sides of the moving block 25. The connecting block 28 is L-shaped and fixedly installed at the bottom of the moving block 25. The rack 29 is fixedly installed at the bottom of the connecting block 28, and the rack 29 is on the same plane as the gear 24. The potentiometer 23 is fixedly installed inside the operating box 21. During operation, pushing the second shaft 18 moves the moving block 25. The bottom end of the moving block 25 is fixedly connected to the connecting block 28, and the other end of the connecting block 28 is fixedly connected to the rack 29. The rack 29 is fixedly connected to the gear 24 at the top of the potentiometer 23. The potentiometer 23 converts the rotation of the gear 24 into an analog voltage signal. The gear 24 and the rack 29 cooperate to convert the mechanical displacement into an electrical signal, reducing linear error. A fixed rod 26 is set to move through the moving block 25. Two sets of compression springs 27 are sleeved on the outer wall of the fixed rod 26. The two sets of compression springs 27 are located on both sides of the moving block 25, which play a reset role for the connecting block 28 and the second shaft 18, taking into account both the operating feel and durability. The potentiometer 23, function button 19, and control switch 12 are all connected to the base 13 for signal transmission.

[0031] The implementation principle of this utility model of a dual-axis multi-functional operating lever is as follows:

[0032] During operation, the user can deflect the main operating lever 14 inside the cavities of the left and right outer shells 15 and 16 by holding the handle housing assembly 10. By setting up the operation panel assembly 11, the user can press the function button 19 on the operation panel body 17 to use the corresponding function. The centralized layout of the function buttons 19 reduces blind spots and improves human-computer interaction efficiency. The second shaft 18 is pushed to move, and the second shaft 18 drives the moving block 25 to move. The bottom end of the moving block 25 is fixedly connected to the connecting block 28, and the other end of the connecting block 28 is fixedly connected to the rack 29. The rack 29 is fixedly connected to the gear 24 at the top of the potentiometer 23. The potentiometer 23 converts the rotation of the gear 24 into an analog voltage signal. The gear 24 and the rack 29 cooperate to convert the mechanical displacement into an electrical signal, reducing linear error. A fixed rod 26 is set to move through the moving block 25. Two sets of compression springs 27 are sleeved on the outer wall of the fixed rod 26. The two sets of compression springs 27 are located on both sides of the moving block 25, which play a reset role for the connecting block 28 and the second shaft 18, taking into account both the operating feel and durability.
