The invention discloses a vertical axis wind turbine with blades capable of being adjusted in a self-adaptive telescopic mode. The vertical axis wind turbine comprises an upper end plate, a lower end plate, a wind facing bent shaft, a sleeve rotating disc and the telescopic blades. An upper end plate limiting barrier strip and a lower end plate limiting barrier strip are arranged on the inner side of the upper end plate and the inner side of the lower end plate respectively, telescopic blades are arranged on the sleeve rotating disc, and arc-shaped metal elastic pieces are arranged in the telescopic blades. The positions of the upper end plate limiting barrier strip and the lower end plate limiting barrier strip are positioned by automatically and oppositely adjusting the wind bending shaft and matching with the real-time wind direction, and the telescopic blades are adaptively adjusted, so that the telescopic blades are in a complete stretching state when the concave surfaces face the wind in the rotating pr
