Abstract
A wire loop adapted to be slung around a tooth to be rotated has two end portions which respectively extend through and are guided by two juxtaposed spaced apart through holes formed in a body. Polygonal roller means are rotatably mounted in said body between said holes and have radially outer edge portions. Said holes are laterally open toward said roller means to expose said wire end portions in said holes to said radially outer edge portions, which bite into the sides of said wire end portions in said holes. Said roller means are rotatable to move said wire end portions in said holes by means of said radially outer edge portions biting into said wire end portions.
