The antitheft umbrella comprises an umbrella handle (10), an umbrella shaft (20), and an umbrella stand (30). A first clip portion (31) is disposed at one end of the umbrella stand (30). The umbrella handle (10) is provided with a hollow portion. A push button (50), an umbrella stand clip block (40) and an umbrella stand clip block return elastic element (401) are sequentially disposed on the umbrella handle (10) from the top to the bottom in a manner of corresponding to the hollow portion. The push button (50) is connected to a password-type lock cylinder structure (60) used for controlling the push button (50) to be free of being pushed at will. The password-type lock cylinder structure (60) comprises a movable shaft (61) and more than one password wheel set (62) mounted on the movable shaft (61). When the umbrella needs to be opened, a correct password is obtained by means of rotations, and the password wheels (623) are linked with rotary wheels (622) to rotate until unlocking grooves (6223) thereof right face unlocking stop blocks (1202). By means of the ingenious design of the password-type lock cylinder structure (60), the password is automatically, mechanically and regularly changed after the umbrella is opened by means of the password wheel set (62), and accordingly, undesirable phenomena such as umbrella losing and theft caused by a fixed password are avoided, thereby facilitating umbrella management and maintenance. In addition, the push button slide control structure for opening and closing the umbrella is ingenious and reasonable in design, the linkage is stable, and the using reliability is good.
