The invention relates to a speed wrench for wire binding. The speed wrench comprises a wire binding plate and an operation rod; the wire binding plate is oval, a wire feeding groove is formed in the direction perpendicular to the major semi axis of the oval, and an ovate wire binding hole is formed in the middle portion of the wire binding plate, wherein the ovate is a shape like an egg outline, one side is small, the other side is large, and the ovate approximates to an oval; and the wire feeding groove (11) is communicated with the wire binding hole, a first connecting pipe is fixedly arranged above the wire binding plate, a second connecting pipe is fixedly arranged above the wire binding plate, a curve face, located at the small head of the ovoid, of the wire binding hole is provided with canine teeth in a boring manner, and one end of the operation rod can be inserted into a pipe cavity of the first connecting pipe or a pipe cavity of the second connecting pipe. Compared with the prior art, the speed wrench is small in size, light and convenient to carry, and the operation rod is detachable; and as the wire binding hole is ovoid, and the curve face, located at the small head of the ovoid, of the wire binding hole is provided with the canine teeth in the boring manner, the wire binding winding forces generated when the operation rod is inserted into the first connecting pipe or the second connecting pipe are different, and convenience is brought to selection according to using conditions.
