The support rod 1001 completes the installation of the side support member 10. Then, the bottom support rod 101 is unfolded and fixed with the first locking stud 402. Next, the transverse isolation rod 201 is unfolded, and the smallest transverse isolation rod 201 is pulled out and placed in the support groove 13. The positioning stud 20 is rotated to fix it. At this time, the bottom support rod 101 and the side support rod 1001 are connected. The bottom plate support rod is pushed to move under the action of the sliding roller 801, so that the transverse isolation rod 201 can be pulled open to form a barrier.
