The invention discloses an integrated and optimized device containing structure. The integrated and optimized device containing structure comprises left and right side plates, left and right supporting parts are arranged on the left and right side plates, a containing device is arranged between the left and right supporting parts and comprises front, middle and rear cross rod telescopic assemblies, front, middle and rear
moving parts are transversely and movably arranged on the front, middle and rear cross rod telescopic assemblies correspondingly, upper connecting rods are detachably arranged on the upper portions of the front, middle and rear
moving parts, notch parts are formed in the lower portions of the front, middle and rear
moving parts correspondingly, in addition, lower connecting rods are detachably arranged on the lower portions of the front, middle and rear moving parts through the notch parts in a penetrating mode correspondingly, the middle cross rod telescopic
assembly and the middle moving part synchronously and longitudinally slides between the front and rear cross rod telescopic assemblies through the cooperation of the upper and lower connecting rods, at least one containing area capable of containing devices and capable of adjusting the longitudinal and / or transverse size is formed between the front, middle and rear cross rod telescopic assemblies and the front, middle and rear moving parts in the moving process, the devices are placed on the containing areas, the bottoms of the devices are positioned and supported on the lower connecting rods in a bearing mode, and the side portions of the devices act on the upper connecting rods and / or the front and rear cross rod telescopic assemblies and / or the middle cross rod telescopic
assembly in a front-back and / or left-right positioning mode.
