Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a telescopic fence according to the present invention, and fig. 2 is a right side view of the telescopic fence shown in fig. 1. In a specific embodiment, the utility model provides a telescopic guardrail's structure includes: the device comprises a main frame 100 and a secondary frame 200, wherein a plurality of cross connecting rods 300 are connected between the main frame 100 and the secondary frame 200 in a hinged manner, and universal wheels 400 are arranged at the lower end of the main frame 100; the two ends of the telescopic guardrail are respectively provided with the main frame 100; between the two ends of the telescopic fence, the main frame 100 and the sub-frame 200 are arranged at intervals.
