Summary:The invention provides a telescopic device with a buffering function. The telescopic device comprises a device base. The main structure of the upper end of the device base is a first-stage sleeve. A second-stage sleeve is embedded in the first-stage sleeve. A third-stage sleeve is embedded in the second-stage sleeve. A gear lead screw shaft in the middle can make a lead screw nut drive the second-stage sleeve to move under the driving of a driving motor set; the driving motor set drives an inhaul cable take-up and pay-off wheel to take up and pay off an inhaul cable at the same time, so that the inhaul cable and a stretching compression spring between the second-stage sleeve and the third-stage sleeve are combined to make the third-stage sleeve move; the stretching compression spring has the buffering function when in a stretching-out state. According to the telescopic device with the buffering function, under the conditions of a small layout space and a narrow weight range, a capturing device installed at th
