摘要： A telescopic rod includes a hollow handle having a longitudinal slit formed in the handle, an alignment coupler slidably engageable in said hollow handle having a truncated tube section formed in the coupler having an upper inclined surface formed on the tube section, and a reel pole secured with a display sheet such as a flag cloth having a lower portion of the pole rotatably held in the coupler having a lower inclined surface tapered downwardly and tangentially engageable with the upper inclined surface of the coupler, so that upon a depression of the pole and sheet, the pole will be rotated for a tangential engagement of the two inclined surfaces to align the display sheet with the slit of the handle for a quicker retraction of the sheet into the handle.
