Reason is, it is only necessary to when boring a kind of diametric hole, the drilling of the first drilling layer is directly controlled, if necessary to the smaller hole of drill straight diameter,
The stretching of the first cylinder is controlled, drives the second drilling layer to protrude from the second drilling layer and can drill out the hole of smaller diameter and similarly passes through
Controlling the second cylinder drives third drilling layer to stretch out, and can bore smaller hole.
The utility model drilling tooth is hinged on the first drilling layer, the second drilling layer and third drilling layer, the first drilling layer,
Tooth socket is provided on second drilling layer and third drilling layer, tooth socket can accommodate drilling tooth, and drilling tooth can rotate radially,
It cannot rotate in the axial direction, tooth socket is disposed radially.The hinged advantage of drilling tooth is, does not need the drilling layer of larger diameter
When, drilling tooth can be pressed in tooth socket, prevent drilling tooth from getting on timber, damage timber.
It is equipped with the first sliding rail in the first linking arm of the utility model, the second sliding rail is equipped in second linking arm,
Second linking arm is connected in the first sliding rail, and third linking arm is connected in the second sliding rail, the first sliding rail and the second sliding rail
Section be it is T-shaped, the second linking arm and third linking arm are stuck in the second sliding rail in the first sliding rail by T shape protrusion cards
It is interior.Linking arm is connected in sliding rail, electric drill can drive all electric drill layers to rotate, while can connect to the second linking arm and third
