The invention relates to the technical field of Internet of Things, and discloses an intelligent stripping device capable of stripping cables of different sizes. The device comprises a base. a fixed plate, a cutting knife, a moving block and a limiting plate are matched for use, cables with different thicknesses can be stripped, a new peeling device does not need to be replaced, the cable can be peeled more conveniently, work efficiency is improved. A first sliding block, a limiting block, a fixing rod, a special-shaped rod and a clamping plate are matched for use. Therefore, cables with different diameters can be clamped; more stable cable stripping is ensured. Therefore, the cable is ensured to be located at the center of the cutting knife during stripping. Through the cooperation of themovable block, a first connecting rod, a sleeve rod, a limiting plate and a cross rod, when a large-size cable is clamped, the cutting thickness can be automatically adjusted, the linkage performanceof the whole device is improved, and the operation is simpler.
