An umbrella supporting mount can be easily and quickly secured to a flat surface of a table or roof of a vehicle in a stable and firm manner without shaking at all. The supporting mount has an integrally punched metal lid of proper height and is equipped with a plurality of vent holes and a pair of symmetric mounting holes on the vertical periphery thereof so as to permit a cranked driving control shaft having a handle at one end to be located in a hollow interior of the lid. A driven unit integrally made of hard plastics consists of a circular base board and a vertically extended block having a driving hole disposed at the center thereof. The circular base board of the driven unit is partially wrapped around by a sucking attachment which is made of flexible rubber and has a peripheral skirt defined at the bottom edge thereof. So, a cranked section of the cranked driving control shaft can be engaged with the driving hole of the driven unit and the activation of the driving control shaft results in the lift up of the driven unit to force air in the skirted area of the sucking attachment out of the lid via the vent holes so as to produce a vacuum effect for firmly fix the supporting mount to a flat surface.
