Multi-rod support device with an enlarged carrying surface

A multi-rod support device, comprising:

• a pivot seat unit having a through hole which defines a central axis;
• a support unit pivotably connected with said pivot seat unit, and including a first rod and two second rods, each of said first rod and said second rods having an upper end portion and a lower end portion opposite to said upper end portion, said upper end portions and said lower end portions being turnable relative to said pivot seat unit between a folded state, where said upper end portions and said lower end portions are close to the central axis, and an unfolded state where said upper end portions and said lower end portions are remote from the central axis;
• and
• a carrying unit including a central plate which is pivotably connected with said first rod, two lateral plates which are respectively and pivotably connected with two lateral edges of said central plate, and two extension plates which are respectively and movably connected with said two lateral plates, each of said extension plates being movable relative to a corresponding one of said lateral plates between a retreat state and an extend state, wherein, during turning of said upper end portions and said lower end portions from the folded state to the unfolded state, said extension plates are moved relative to said lateral plates and are shifted from the retreat state to the extend state, where said upper end portions of said two second rods abut against a bottom portion of said carrying unit.
