摘要：
The present invention relates to a support for a pole and footrest of a stool. The support comprises: a lower body and an upper body, wherein the lower body comprises a lower portion and an upper portion with a recess for inserting the pole and mortises in the side walls for coupling supporting spokes of a footrest; and the upper body comprises side walls and has a through-opening passing through same and a recess aligned with the recess for inserting the pole, wherein the side walls comprise mortises that complement the mortises comprised in the upper portion.
技术问题语段：
The technical problem addressed in this patent is the inefficient and unoptimized packaging of stools due to the one-piece or large parts welded together, which prevents the packing and packaging from being optimized for transportation. The invention provides a support for the pole and footrest of a stool that is made up of parts with a small volume and high robustness, allowing for optimal and practical packaging. The support is easy to assemble and does not require tools.
