Utility model content
In view of this, the utility model is directed to a kind of deep thread hole screw tap and its extension rod, to facilitate body threaded hole
Processing.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of deep thread hole screw tap, including ontology, top is provided with blind hole along axial direction, and the bottom hole of blind hole is provided with torque
Slot.
Morse shank is extended in a kind of extension rod of deep thread screw tap, including the body of rod, described body of rod one end, and the other end is along axial
A plurality of claw is extended outward, and there are expansion gap between every two adjacent claws, two adjacent claws can be located remotely from each other.
Further, the post extends downwardly and outwardly out horn mouth, and expansion gap is upwardly extended horn mouth point
For more valves；Tensioner ring is arranged on the body of rod, the one end of the tensioner ring extends the branch opposite with horn mouth inwardly
Support platform.
Further, the body of rod side extends outward screw thread platform, and one end far from supporting table is set on the tensioner ring
There is internal screw thread.
Further, there are expansive spaces between the tensioner ring and horn mouth.
Further, the supporting table side opposite with horn mouth is equipped with inclined-plane.
Further, the claw bottom end is equipped with multiple fins.
Compared with the existing technology, a kind of deep thread hole screw tap and its extension rod described in the utility model have following excellent
Gesture:
The utility model is used in screw tap top drilling, and the mode that extension rod is inserted makes to extend to your diameter
Less than the diameter of screw tap, facilitate the processing of deep hole thread.
