[0025] According to the present specific embodiment, the mounting seat 102 is fixedly connected to the top of the micro-tillage machine body 101, and is used to install the power assembly and the rotating shaft 104. The power assembly is located on one side of the mounting seat 102, and the rotating shaft 104 is rotatably connected to the top of the mounting seat 102. The rotating frame 105 is fixedly connected to the surface of the rotating shaft 104. The stretching frame 106 is slidably connected to the rotating frame 105 and is located on the side away from the micro-tillage machine body 101. The fixing assembly is located on one side of the stretching frame 106. Before using the micro-tillage machine, the fixing assembly is opened and the stretching frame 106 is pulled to adjust the height of the stretching frame 106. The power assembly is started, and the rotating shaft 104 starts to rotate, driving the rotating frame 105 to rotate, thereby driving the stretching frame 106 to rotate to adjust the angle of the stretching frame 106. After the angle and height of the stretching frame 106 are appropriate, the power assembly is closed, and the stretching frame 106 is fixed using the fixing assembly, and the position adjustment of the stretching frame 106 is completed.

[0026] The rotating frame 105 is provided with a plurality of height holes 114, and each of the height holes 114 on the inner wall of the rotating frame 105 is provided with a fixing groove 115. The fixing cylinder 107 is fixedly connected to one side of the stretching frame 106 and communicated with the stretching frame 106. The fixing shaft 108 is slidably connected to the rotating frame 105 and passes through the fixing cylinder 107. The spring 109 is fixedly connected to the fixing cylinder 107 and the fixing shaft 108 and is located in the fixing cylinder 107. When fixing the stretching frame 106, the fixing cylinder 107 needs to be aligned with one of the fixing holes 114 and moved to the stretching frame 106. The fixed shaft 108 is pressed downward to make the lower end of the fixed shaft 108 enter the rotating frame 105, and then the fixed shaft 108 is rotated to align the lower end of the fixed shaft 108 with the fixing groove 115, and then the fixed shaft 108 is released, and the spring 109 is reset to push the fixed shaft 108 upward to make the lower end of the fixed shaft 108 stuck in the fixing groove 115, and the rotating frame 105 and the stretching frame 106 are tightened, and stuck in the fixing hole 114 and the fixing cylinder 107 at the same time, so that the stretching frame 106 cannot slide, and the height of the stretching frame 106 is fixed.

[0027] Secondly, the rotating base includes a fixed seat 110 and a connecting seat 103, which are used to enable the electric telescopic rod 111 to rotate relative to the micro-tillage machine body 101 and the rotating frame 105. The connecting seat 103 is rotatably connected to the fixed seat 110, and two connecting seats 103 are respectively fixedly connected to the bottom and output end of the electric telescopic rod 111. One fixed seat 110 is fixedly connected to the top of the micro-tillage machine body 101, and the other fixed seat 110 is fixedly connected to the bottom of the rotating frame 105. When adjusting the inclination angle of the rotating frame 105, the electric telescopic rod 111 is started, and the electric telescopic rod 111 is telescoped, so that the two connecting seats 103 rotate relative to the two fixed seats 110. At the same time, the length of the electric telescopic rod 111 changes, so that the angle between the rotating frame 105 and the micro-tillage machine body 101 changes. After the angle of the rotating frame 105 is appropriate, the electric telescopic rod 111 is closed, and the angle adjustment of the micro-tillage machine frame is completed.

[0028] At the same time, the torsion plate 112 is fixedly connected to the fixed shaft 108 and is located on the side away from the spring 109. The grabbing sleeve 113 is fixedly connected to the stretching frame 106 and has a mesh-like depression on its surface. When the fixed shaft 108 is used, the torsion plate 112 can make the pressing and twisting of the fixed shaft 108 easier; when the stretching frame 106 is used to push and pull the micro-tillage machine, the grabbing sleeve 113 can make the operator's grip more stable, prevent slipping, and improve the use efficiency of the micro-tillage machine.

[0029] Before using the micro-tillage machine, press and rotate the torsion plate 112, and release it after the lower end of the fixed shaft 108 is aligned with the fixing hole 114, so that the spring 109 brings the fixed shaft 108 out of the rotating frame 105, pulls the stretching frame 106, adjusts the height of the stretching frame 106, and starts the electric telescopic rod 111 at the same time. The electric telescopic rod 111 is telescoped to make the two connecting seats 103 rotate relative to the two fixing seats 110. At the same time, under the action of the rotating shaft 104, the change in the length of the electric telescopic rod 111 will change the angle between the rotating frame 105 and the micro-tillage machine body 101, thereby adjusting the angle of the micro-tillage machine frame. After the angle of the rotating frame 105 is appropriate, close the electric telescopic rod 111; at the same time, the fixing cylinder 107 can be aligned with the fixing hole 114 at a suitable position, and the torsion plate 112 is pressed downward. The fixed shaft 1 08 moves downward, and at the same time, the spring 109 is squeezed, so that the lower end of the fixed shaft 108 enters the rotating frame 105, and then the fixed shaft 108 is rotated to align the lower end of the fixed shaft 108 with the fixing groove 115, and then the fixed shaft 108 is released, and the squeezed spring 109 is reset, and the fixed shaft 108 is pushed upward, so that the lower end of the fixed shaft 108 is stuck in the fixing groove 115, and the rotating frame 105 and the stretching frame 106 are tightened, and stuck in the fixing hole 114 and the fixing cylinder 107, so that the stretching frame 106 cannot slide, and the height of the stretching frame 106 is fixed. At this time, the height and inclination of the micro-tillage machine frame are adjusted, avoiding the problem that the prior art cannot adjust the height of the micro-tillage machine frame, cannot adapt to users of different heights, and has poor practicality, and obtains the effect of adjusting the frame height and angle to improve work efficiency.
