The bottom of the gas spring 22 is provided with a gas spring valve 23. A first end of the pedal arm 26 is connected to the pedal 25, and a second end of the pedal arm 26 is pivotally connected to the gas spring connecting bracket 24. One end of a tension spring 27 is connected with the frame column 1, and the other end of the tension spring 27 is connected with the middle part of the pedal arm 26. When the pedal 25 is stepped on, the second end of the pedal arm 26 presses the gas spring valve 23 upward, so that the gas spring 22 is opened. Preferably, the second end of the pedal arm 26 is provided with a ramp 261 that slopes outwardly and downwardly, the ramp 261 contacting the gas spring valve 23 upwardly and triggering the gas spring valve 23 when the pedal 25 is depressed. After the gas spring valve 23 is triggered, the gas spring 22 is opened, the steering gear can be adjusted to a required angle, then the pedal 25 is released, the pedal arm 26 returns to the initial position under the pulling of the tension spring 27, the gas spring 22 is closed, and the steering gear angle is fixed.
As shown in fig. 1 and 2, the upper part of the frame column 1 is further provided with a height adjusting mechanism, and the height adjusting mechanism comprises a spline housing 35, a spline shaft 32, a mandrel 31 and an eccentric wheel 34. The spline housing 35 is arranged inside the rack pipe column 1 and rotatably mounted with the rack pipe column 1 through the bearing 5, the spline housing 35 can rotate around the axis of the spline housing 35 under the support of the bearing 5, and the bottom of the spline housing 35 is used for being connected with a steering gear. The lower portion of spline shaft 32 extends into spline housing 35 and is in splined connection with spline housing 35, spline shaft 32 can slide axially in spline housing 35, the upper end of spline shaft 32 is used for being fixedly connected with steering wheel 6 of the steering gear, and rotation of the steering wheel can drive spline shaft 32 and spline housing 35 to rotate relative to frame tubular column 1.
