description The invention discloses a telescopic control valve, a multi-oil-cylinder sequential telescopic control mechanism and a multi-oil-cylinder driving device. The multi-oil-cylinder driving device comprises a first-stage oil cylinder and a second-stage oil cylinder, a mechanical touch switch is installed on the first-stage oil cylinder, and an adjustable touch pin is installed on the second-stage oil cylinder; and when the piston rod of the second-stage oil cylinder extends to a set position, the adjustable touch pin touches the mechanical touch switch, and the mechanical touch switch cuts off hydraulic oil of a rodless cavity of the first-stage oil cylinder. The multi-oil-cylinder sequential telescopic control mechanism has the advantages that the structure is reasonable, the reliability of atelescopic arm is effectively improved, and the machining difficulty of an arm frame and the oil cylinder is not required to be increased. 本发明公开了种伸缩控制阀、多油缸循序伸缩控制机构及多油缸驱动装置,多油缸驱动装置,包括第1级油缸和第2级油缸,所述第1级油缸上安装有机械式触碰开关,所述第2级油缸上安装有可
