A sliding-type electronic apparatus with a strengthening force structure includes a body served as a system terminal and an upper cover disposed on the body and having a surface configured with a touch screen. A sliding and cover-lifting member constituted by a sliding rail, a sliding member and a pivot shaft device is at least disposed between the body and the upper cover. In a normal state, a supporting device, together with the sliding and cover-lifting member, is horizontally and supportively placed in a preset concave chamber space of the body. The auxiliary supporting devices can be formed as an inclined auxiliary support structure on the rear surface of the upper cover when the upper cover is lifted, thereby effectively increasing the screen touch resistance to inhibit screen wobble in an operation process and to promote the support effect and operation stability of the screen.
