[0034] Working principle: we support the support leg 1 to fix the support plate on the highway, and then hold the rotating plate 3 to rotate around the opening plate 2. When the concave plate 4 is close to the ground after the rotating plate 3 rotates, the nail column 5 can be adjusted by rotating the concave plate 4. Then the whole nail column 5 is mixed into the soil. Then slide the sliding rod 6 downward to push the connecting rod 11 to slide, and then push the fan-shaped plate 12 to slide. At this time, the anti-falling plate 13, the fan-shaped plate 12 and the trapezoidal plate 14 are rotated and limited, which makes the anti-falling plate 13 rotate when the fan-shaped plate 12 slides downward, so as to push the trapezoidal plate 14 to slide outward and insert into the soil. When the sliding rod 6 cannot slide, the nut 8 is screwed on the outer part of the sliding rod 6, and the pressing plate 9 is pushed to rotate the nut 8. As the nut 8 moves to the middle of the sliding rod 6, it is clamped in the inner part of the nail column 5 when it cannot rotate, thereby completing the clamping and fixing of the trapezoidal plate 14 and transmitting the support force to the support leg 1, thereby improving the stability of the support leg 1 and improving the overall protection performance, reducing the security risk;
[0035] And when the vehicle hits the impact plate 28, the impact plate 28 will push the two dampers 18 and the plurality of square plates 27, at this time the square plates 27 will push the rotating plate 25 to slide, and the square plates 27 will push the rotating plate 25 to slide in the process of sliding, and the rotating plate 25 will be limited in the threaded openings 20 opened on both sides of the fixed cylinder 19 by the rotating column 26, at this time the rotating plate 25 will rotate and drive the rotating column 26 and the inside of the fixed cylinder 19 to generate friction, and then the rotating plate 25 will push the connecting plate 24 to slide, thereby pushing the abutment plate 23 to slide, and then pushing the circular plate 22 to slide and extruding the strong spring 21, so that the strong spring 21 can store elastic potential energy, and then the force in the opposite direction is transmitted to the square plate 27, and the friction generated by the rotating plate 25 driving the rotating column 26 to rotate and the damper 18 cooperate with each other, so that they can give the impact plate 28 to reduce the impact force of the vehicle, so as to reduce the damage of the guardrail and the vehicle, thereby reducing the replacement cost.
[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
