[0023] The specific implementation process of the utility model is as follows: During construction, it is necessary to place a guardrail outside the construction site. The patent sets a guardrail with adjustable length. When the guardrail is used, if the guardrail protection length needs to be adjusted, first fix the first fence post 1 at the specified position, and then the operator pulls the second fence post 2, and pulls the second fence post 2 to the side away from the first fence post 1, and drives the sliding rod 5 and the pull rod 7 to move together with the second fence post 2. The block 10 set on the pull rod 7 squeezes the inclined surface on the stopper 14 through the inclined surface, and the stopper 14 drives the connecting rod 13 to retract downward at the same time. After the degree adjustment is completed, the second fence post 2 is no longer pulled. At this time, the two springs 11 set on the connecting rod 13 push the connecting rod 13 and the plurality of blocks 14 to reset. At this time, the block 14 is inserted into the middle of the plurality of blocks 10 to form a limit to prevent the second fence post 2 from sliding and shrinking. When it needs to be retracted and reset after use, an operator needs to step on the pedal 8 with his foot, and at the same time drive the connecting rod 13 and the block 14 to move downward together through the support 9. At this time, the block 14 no longer forms a limiting effect on the block 10, and then another staff member pushes the second fence post 2 towards the first fence post 1.
