rocker rotating shaft 8, and the bottom of the rocker 7 is connected to the Y-axis spring limit 13. ;

[0036] Installation method and principle of use: install the assembly components of the X-axis spring box 4 into the base 1, and then install the Y-axis PCB box 22 on the Y-axis spring box 10, lock it with four screws, and then fix the X-axis spring box 4 on the base 1 with the elastic pin 25. The upper end of the rocker 7 is equipped with an upper end interface 9, and then assemble the rocker assembly and the remaining spring box assemblies into the base, install the top cover 2 on the base and press it, fix the top cover 2 with 4 screws, and then use screws to fix the X-axis PCB box 21 on the base 1, and finally use four screws to fix the bottom cover 2 on the base 1. The installed X-axis PCB box 21 and Y-axis PCB box 22 are located at the center of the magnetic steel on the axis. The rocker rotating shaft 8, rocker 7 and GFM-1516-03 bearing 23 are components pre-assembled in the spring box, and their function is the swinging part of the handle. Installation of the Y-axis spring box 10: During the assembly process, first install the Y-axis slider 17 in the Y-axis spring box 10, then install the Y-axis slider spring 19 into the spring fixing groove of the Y-axis slider 17, then cover the Y-axis spring box end cover 12 and the Y-axis double-axis spring box end cover 11 on both sides, and tighten the four screws on the end cover to complete the assembly of the Y-axis spring box partial structure. The assembly process of the X-axis spring box 4 is basically similar to that of the Y-axis spring box 10, and will not be repeated. It should be noted that when fixing the X-axis spring box 4 and the Y-axis spring box 10, insert the convex shaft at the lower end of the Y-axis spring limit 13 into the X-axis spring limit 6 to achieve linkage. The core components of the upper part of the rotating structure are the rocker 7, the rocker rotating shaft 8, the upper end interface 9, the GFM-1516-03 bearing 23, and the elastic pin 25. The function of these components is to serve as the driving components of the joystick. When the upper end interface 9 is connected to the upper handle, by pushing the upper handle and driving these driving components at the same time, the human action can be converted into mechanical movement. When the mechanical moving parts are driven by human operation, the lower part of the rocker 7 can be pushed to the Y-axis slider 17, and the lower end of the rocker 7 is fixed with a Y-axis spring limiter 13. After the Y-axis spring limiter 13 is driven by the rocker 7, it can push the Y-axis slider 17 to swing during the Y-axis movement. At the same time, the Y-axis slider 17 moves against the Y-axis slider spring 19. The Y-axis slider spring 19 will also have a reaction force (or reset force) on the Y-axis slider 17 and the Y-axis spring limiter 13. When the operating force of the operator is removed, the Y-axis spring limiter 13 can push the Y-axis slider 17 to the rocker / Y-axis spring limiter, so that the middle position can be stable. The Y-axis spring limiter 13 can make the rocker 7 rotate smoothly on the X-axis, and can be effectively driven by the rocker 7 to swing when the rocker 7 swings on the Y-axis. The two are fixed by the small hole of the Y-axis spring limiter in the BB section.Similarly, the lower end of the rocker 7 is located in the middle of the two X-axis sliders 16 in the X-axis spring box 4. The Y-axis spring limit 13 at the lower end of the rocker 7 has no limit effect on the rocker 7 in the X-axis. Therefore, the rocker 7 can slide freely in the X-axis, so that the rocker 7 can freely push the X-axis slider 16 to move in the X-axis spring box 4. When the X-axis slider 16 moves, it is subjected to the reaction force of the X-axis slider spring 18, that is, the reset force. When the driving force of the rocker 7 or the upper handle on the upper part of the rocker 7 is removed by human action, the X-axis slider spring 18 can enable the entire joystick to be smoothly reset to the original X-axis center position in the X-axis.

[0037] In view of the problem of the current center offset of the excavator joystick, the present invention designs a spring centering solution to have a certain pre-pressure on the center position, so that the center gap of the joystick can be as small as possible, tending to be stable; in view of the fact that the service life of the current excavator joystick cannot meet the service life of the whole machine, a stainless steel groove structure with good self-lubrication and wear resistance is used, so that the structure can wear to the minimum extent, and no mechanical breakage or failure will occur after wear; in view of the current problem of difficulty in replacing the upper handle, the present invention adopts the form of an upper end interface, which can replace the upper end more simply and conveniently while cooperating with the upper end for assembly; the overall structure is reasonable and compact, easy to install and disassemble, and thus convenient to replace the X-axis spring box 4 and the Y-axis spring box 10; the X-axis spring box 4 and the Y-axis spring box 10 have simple structures, easy to install and disassemble, and thus convenient to repair the X-axis spring box 4 and the Y-axis spring box 10.

[0038] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0039] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
