Anchor rod locator relates to a anchor rod locator. In the actual construction, the easy center deviation of stock, the reliability is not strong, and the concrete fills the in -process moreover, collides easily, turns over, and stability is not strong. The utility model discloses a fixing device, positioner, fixing device include many positioning bolt, and a plurality of cylindrical mound and themound that will shear of shearing that positioner includes locating ring, located the circular ring below in location is connected to the bolt that shears on the locating ring, a plurality of first screws that match with positioning bolt are seted up to locating ring's side, positioning bolt and locating ring's first screw threaded connection, and positioning bolt's tail end can be overhanging inlocating ring's inner circle in order to offset with the stock. This technical scheme makes simply, and is with low costs, light in weight, and the size is little, portable, convenient operation is swift, and it can through positioning adjustment screw length, locating ring diameter size, the mound that shears distribution, realize that the stock of different apertures, different stock diametersis fixed according to actual construction situation.
