The invention relates to a pipe fitting telescoping mechanism and a baby carriage. The pipe fitting telescoping mechanism comprises an outer pipe; the inner pipe is sleeved in the outer pipe in an axial moving manner; the locking device comprises a locking piece and a traction piece which are arranged in the inner pipe, and the locking piece is operably connected with the traction piece; the locking piece has a locking state for limiting the axial movement of the inner pipe relative to the outer pipe and an unlocking state for allowing the axial movement of the inner pipe; when the traction piece moves under the action of traction force, the locking piece is driven to be switched from the locking state to the unlocking state; and when the traction force is withdrawn, the locking piece has a trend of returning to the locking state from the unlocking state.
