[0011] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: 1. When the two meshing transmission gears rotate in the forward direction, that is, when the double fork arms are lifted, the area between the oil inlet 1 and the two transmission gears in the transmission chamber is in a low-pressure area due to the separation of the teeth of the two transmission gears. At this time, the hydraulic oil enters the transmission chamber from the oil inlet 1, and the hydraulic oil is entrained by the space formed by the transmission gear and the transmission chamber, and is brought to the side where the teeth of the two transmission gears mesh along the inner wall of the transmission chamber. On this side, due to the meshing of the teeth, the hydraulic oil between the teeth is squeezed out, forming a high-pressure area, and then the hydraulic oil is transported to the oil storage cylinder through the oil delivery adjustment component. This process can absorb and buffer vibration energy. When vehicles and other equipment pass through bumpy roads, the spring is compressed, the shock absorber piston moves downward, and the hydraulic oil enters the oil storage cylinder through the valve. This process is like a buffer. For example, when a car encounters a bump while driving, the wheel moves upward, and the main spring is compressed. The flow of hydraulic oil can reduce the compression speed of the main spring, avoid sudden sinking of the car body, and make the driving experience more comfortable. Secondly, this process can adjust the damping force.

[0012] 2. Through the adaptation of the threaded hole and the screw rod, when the screw rod rotates, the connecting block moves up and down, thereby driving a number of shock-absorbing springs fixedly connected to the connecting block to move up and down. The shock-absorbing springs move upward until their upper ends abut against the stopper and stop. At this time, the shock-absorbing springs cooperate with the main spring on the shock absorber. This arrangement makes the way of adjusting the shock absorption more diverse and the shock absorption effect better.

[0013] 2. The outer sleeve rotates to drive the straight groove to rotate, and the straight groove rotates to drive the push rod 2 to slide in the straight groove, thereby driving the push rod 1 and the turntable connected thereto to rotate. Due to the limiting effect of the polygonal slide groove on the turntable and the inclined groove on the adjusting tube, when the turntable rotates, several polygonal blocks slide toward the axis of the turntable or away from the axis, thereby making the size of the opening of the hydraulic oil through the turntable and the adjusting tube adjustable. By controlling the flow and speed of the hydraulic oil entering the oil storage cylinder, which is determined by the characteristics of the valve, the damping characteristics of the shock absorber can be changed.

At the same time, when the piston rod is pressed down, the oil quantity delivery adjustment component 22 can be adjusted according to the downward stroke of the piston rod. When the personnel feel that the suspension shock absorption effect is not good, by starting the power component 41, the power component 41 pushes the spring component 42 to move upward to cooperate with the shock absorption work of the main spring on the shock absorber 1.
