In the utility model, the second isolation exhibition fence is slid to the right on the sliding rod to expand to the required length, and is fixed with a fixing bolt to facilitate the length adjustment, and the wheels are extended to contact the ground through the rod body of the second micro electric telescopic rod, so as to facilitate the movement and transportation of the guardrail.
[0003] The existing guardrails have poor flexibility. Generally, the length of guardrails is produced according to customer needs. Once produced, the length is difficult to adjust and cannot be flexibly adjusted according to usage, which reduces practicality and applicability. In addition, the existing guardrails are fixed in length, which is inconvenient to store and occupies a large space when stored, increasing the cost of storage and transportation. They are inconvenient to use and cannot be adjusted in height. Generally, the height of guardrails is fixed. During use, it is necessary to select guardrails of different heights according to usage. Generally, the entire guardrail is replaced, which is not only troublesome, but also increases the cost of use and reduces practicality and applicability.
