[0024] The effect achieved by the entire embodiment 1 is that when it is necessary to adjust the assisting force of the assisting device, firstly rotate the fixing device 8 so that it no longer fixes the adjusting column 7 and the threaded rod 10, and then, under the action of the connecting device 6, the adjusting column 7 is rotated to make the threaded rod 10 rotate inside the movable groove 9, so as to adjust the tension of the assisting spring 11. When the assisting force is adjusted to an appropriate value, the fixing device 8 is rotated again to fix the adjusting column 7 and the threaded rod 10 again. Through the above structure and method, the strength of the assisting device can be adjusted according to the habits of different drivers, thereby greatly improving the use effect of the assisting device.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, two support frames 14 are fixedly installed on the outer wall of the adjusting rod 4, and an insertion groove 15 is provided on one side of the outer wall of the two support frames 14. Limit rods 16 are movably inserted on the inner walls of the two insertion grooves 15, and two compression springs 17 are fixedly installed on one side of the outer wall of the two limit rods 16. A square groove 18 is provided on one side of the outer wall of the adjusting rod 4, and a pedal body 19 is movably inserted on the inner wall of the square groove 18. Two groups of limit grooves 20 are provided on the outer wall of the pedal body 19, and two installation grooves 21 are provided on one side of the outer wall of the outer shell 1, and a hydraulic device 22 is movably inserted between the inner walls of the two installation grooves 21.

At the same time, the limit rod 16 can be moved toward the middle in the insertion slot 15 under the action of the compression spring 17 and limit the pedal body 19 under the action of the limit slot 20, thereby improving its practicality. When the power assisting force of the power assisting device needs to be adjusted, first, the fixing device 8 is rotated so that it no longer fixes the adjusting column 7 and the threaded rod 10, and then the connecting device 6 is used to fix the adjusting column 7 and the threaded rod 10. The threaded rod 10 is rotated in the movable groove 9 by rotating the adjusting column 7, so as to adjust the tension of the assisting spring 11. When the assisting force is adjusted to a suitable value, the fixing device 8 is rotated to fix the adjusting column 7 and the threaded rod 10 again, so as to complete the adjustment of the assisting force. When the clutch pedal is assisted, the hydraulic oil enters the hydraulic device 22 through the filtering device 24 and the oil pipe 23 and can also assist the clutch pedal under the action of the mounting block 26. At the same time, the hydraulic oil can be filtered under the action of the filtering device 24 to avoid impurities in the hydraulic oil, so as to achieve the effect of uniform assisting the clutch pedal.
