The invention discloses a two-point clamping type optical fiber perform clamping and suspending device. The two-point clamping type optical fiber perform clamping and suspending device comprises a base, a suspending device, an upper clamping and suspending device and a lower clamping and suspending device. The upper clamping and suspending device comprises an upper clamping ring, an upper clamping column, an upper driving device and an upper clamping head. A first installing groove for the upper end of an optical fiber perform to penetrate is formed in the first bottom face of the upper clamping head. The upper end of the optical fiber perform is located between the first installing groove and a first connecting plate. The lower clamping and suspending device comprises a lower clamping ring, a lower clamping column, a lower driving device and a lower clamping head. A second installing groove for the lower end of the optical fiber perform to penetrate is formed in the second bottom face of the lower clamping head. The lower end of the optical fiber perform is located between the second installing groove and a second connecting plate. When the upper end of the optical fiber perform is embedded in the first installing groove in the first bottom face on the upper clamping head, clamping of the optical fiber perform is achieved, the lower end of the optical fiber perform is embedded in the second installing groove in the second bottom face on the lower clamping head, and clamping of the optical fiber perform is achieved; the optical fiber perform is driven by the two driving devices to move in the direction far away from a vertical rod till the optical fiber perform falls at a preset position.
