The invention relates to the electric power line maintaining tool technology and provides an aluminum wrapping tape winder. The aluminum wrapping tape winder includes a winder body, wherein the winderbody includes a first baffle plate and a second baffle plate, the middle of the first baffle plate is provided with a rotation shaft in a penetration mode, a side surface of a first end of the rotation shaft is provided with a connection portion, and the connection portion is used for connecting with one end of an aluminum wrapping tape when the first end of the rotation shaft is inserted betweenthe first baffle plate and the second baffle plate. The aluminum wrapping tape winder is advantaged in that during use, the connection portion is connected with one end of the aluminum wrapping tape,when the rotation shaft rotates, the aluminum wrapping tape is wound on the rotation shaft, after being wound, the rotation shaft or the second baffle plate is pulled to move, the rotation shaft is made to move along the horizontal direction relative to the first baffle plate, the wound aluminum wrapping tape is driven through a side surface of the first baffle plate to separate from the rotationshaft, the aluminum wrapping tape is taken out, the winder body is reset, operation is simple, the winding speed is fast, the winding effect is good, winding is not influenced by proficiency of workers, and the aluminum wrapping tape winder is simple in structure, is convenient to manufacture, is low in cost and has strong practicality.
