Stretch bender clamp

The utility model relates to a stretch bender clamp which comprises a clamp frame, the clamp frame is provided with a bottom plate and two oppositely-arranged side plates, a sectional material is arranged in the clamp frame, the sectional material abuts against the bottom plate and one of the side plates, a clamping assembly is arranged on the sectional material, and the clamping assembly is connected with a pressing block. According to the stretch bender clamp, the clamping effect on a sectional material can be achieved through downward pressing of the pressing block, specifically, the pressing block is pressed downwards, the inclined clamping groove slides relative to the inclined clamping flange, and due to the fact that the inclined face is matched with the inclined face, inclined acting force can be generated on the fixing block; the acting force is further decomposed into the force acting on the horizontal supporting plate and the force acting on the vertical supporting plate, and therefore the effect o
