A telescopic type collision energy absorption device includes a first tube, a second tube telescoped within the first tube, and a telescopic mechanism connected with the second tube by passing through the first tube, the first tube being mounted with a cutting mechanism for cutting an outer wall of the second tube, when the device is in a non-operating state, the telescopic mechanism pulls the second tube to retract into the first tube; in a state prior to the collision of a vehicle, the telescopic mechanism under an effect of high-pressure air pushes the second tube to eject outwards, the cutting mechanism is pressed against locating slots of the second tube under an effect of a spring force, the cutting mechanism cuts the second tube and absorbs energy when the second tube is subjected to an external force and retracts towards interior of the first tube.
