Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1: a but height-adjusting's sedan-chair top guardrail structure in this embodiment installs on the sedan-chair top, its characterized in that: comprises a fixed rod 1, a movable rod 2, a first rail 3 arranged on the fixed rod 1 and a second rail 4 arranged on the movable rod 2; the fixed rod 1 is installed on the top of the car, the movable rod 2 is arranged in the fixed rod 1, the movable rod 2 can stretch out and draw back in the fixed rod 1, and the height of the guardrail on the top of the car can be adjusted by adjusting the position of the movable rod 2 in the fixed rod 1.
