Folding-type crawling body builder with linkage mechanisms

The invention discloses a folding-type crawling body builder with linkage mechanisms. The crawling body builder is provided with a front track and a rear track, wherein the front track and the rear track are movably connected together. The front track is provided with an upper limb sliding body connected with the front linkage mechanism, the rear track is provided with a lower limb sliding body connected with the rear linkage mechanism, the front linkage mechanism is movably connected with the rear linkage mechanism, and the upper limb sliding body and the lower limb sliding body are provided with linkage cables and/or flexible belts. Being foldable, the folding-type crawling body builder with the linkage mechanisms occupies a small storage space; the linkage function is kept, and the crawling body builder is simple in structure and convenient to operate and can improve body building effect.
