Ring is located at housing top, and the inner hole of the housing is made of the threaded hole on top and the cone mouth of lower part, the big end of cone mouth downward, institute
It states threaded hole, internal screw thread locating snap ring to be attached with shank upper portion side wall by internal and external threads, shank lower part right side wall
It is equipped with one of container, container top slot bottom is equipped with the counterbore of wall surface on the left of connection shank, and counterbore is equipped with compression screw,
It is fixed with spring in compression screw, knife handle is equipped with inside the container, is hinged on the inner wall of container two sides in the middle part of knife handle, institute
It states knife handle bottom and is fixed with grooving cutter, knife handle top right side is equipped with the tip of protrusion, and tip relies in cone mouth, the knife handle top
Connecting spring on the left of portion, the shank lower end are equipped with a guide head, and guide head is upper shield structure, the periphery of guide head and
The cooperation of the hole to be slotted.
In order to further perfect, the guide head central upper portion is equipped with shrinkage pool, and the boss on shrinkage pool and shank lower end carries out
Cooperation, guide head lower central connect boss by sunk screw.
Further perfect, the grooving cutter is fixed on knife handle bottom by two screws, and grooving cutter is arranged perpendicular to knife handle.
Further perfect, the receiving trench bottom is equipped with chip removal inclined-plane, between chip removal inclined-plane and knife handle bottom exist centainly
Gap.
Further perfect, the periphery diameter of the guide head is greater than the diameter of shank lower part.
The utility model has the advantages that: 1, the utility model reduces the requirement of cross-notching equipment, common driller,
Device to hole internal recessing is realized on center lathe or disk machine；2, the utility model has lever by the way that one is arranged inside container
The mode of the knife handle of structure, improves working depth of the slot in hole, and practicability is good；3, knife handle bottom is fixed with grooving cutter, adds
The distance that working hour knife handle stretches out is small, and rigidity is good, it is not easy to cause to shake, grooving cutter is not easy to fracture in processing.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: a kind of hole internal recessing tool in the present embodiment, including shank 7 and grooving cutter 6,7 top of shank
It is used to the internal screw thread locating snap ring 4 of fixed jacket 3 equipped with a housing 3 and one, the internal screw thread locating snap ring 4 is located on housing 3
The inner hole on side, the housing 3 is made of the threaded hole 301 on top and the cone mouth 302 of lower part, and the big end of cone mouth 302 is downward, described
Threaded hole 301, internal screw thread locating snap ring equal 4 are attached with 7 upper portion side wall of shank by internal and external threads, 7 lower right of shank
Side wall is equipped with one of container 8, and 8 top slot bottom of container is equipped with the counterbore 9 of connection 7 left side wall surface of shank, and counterbore 9 is equipped with
