The present invention relates to the technical field of concrete 3D equipment printing, and in particular discloses a telescopic cantilever structure and a 3D printing device. The telescopic cantilever structure comprises a fixed frame, a telescopic frame, a balancing component, a sensor and a control component. The telescopic frame is connected to a sliding cavity of the fixed frame by a sliding connection, so that the telescopic frame can move freely in the sliding cavity. When the telescopic frame extends outward to a certain length relative to the fixed frame, the sensor arranged between the fixed frame and the external supporting structure senses the pressure change and sends a signal to the control component. The control component instructs the driving component to drive the balancing component to move according to the received signal to offset the downward pressure generated by the telescopic frame. Through this balancing mechanism, the contact force between the fixed frame and the external supporting structure is stabilized, thereby ensuring the stability of the entire telescopic cantilever structure, while reducing the weight of the fixed frame body, so as to facilitate the transportation of the telescopic cantilever structure.
