Switch through power driven tools anchor so that moveable anchor is aligned with work anchor hole location, rotation is convenient, and can 360 ° of rotations.
The technical scheme to solve the above technical problems is that a kind of tool anchor device of adjustable hole location, including
Moveable anchor disk ontology, steel ball and cover board；The edge of the moveable anchor disk ontology is equipped with multiple through-holes, edge in each through-hole
The direction that the through-hole extends is equipped with two steel balls to contact with each other, the edge of the rear end face of the moveable anchor disk ontology
It is equipped with a circle cover board, the limit rolled close to the steel ball of the rear end face of the moveable anchor disk ontology by the cover board
In the rear end of the through-hole, the moveable anchor disk ontology is mounted in jack by pressure ring assembly for position, and close to the work
The steel ball rolling for having the front end face of anchor disk ontology limits in the front end of the through-hole and contacts the inner wall of the jack.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the pressure ring assembly includes lower pressure ring, middle pressure ring and connection bolt, the lower pressure ring and medium pressure ring
It is linked together by connection bolt superposition, when installation, the moveable anchor disk ontology is limited in institute by the pressure ring assembly
State in jack, and the lower pressure ring pushes down the cover board, the pushing ring surface is equipped with arc groove, the arc groove with it is described
Steel ball contact.
Further, the pressure ring assembly further includes connecting rod and upper press ring, and one end of the connecting rod is fixed in described
On pressure ring, the other end of the connecting rod stretches out the jack and connect with the upper press ring, and the upper press ring is embedded in institute
It states in the rear end face of jack.
The beneficial effects of the present invention are: the present invention is that multiple through-holes are beaten on the edge of moveable anchor disk ontology, each through-hole
Two steel balls are placed, and are directly installed on above moveable anchor disk ontology with cover board by screw, steel ball is just limited in by cover board logical
Kong Zhong；Moveable anchor disk ontology will be installed to be put into inside jack, then with pressure ring assembly be limited in moveable anchor disk ontology very heavy
Top the inside carries out axial restraint, steel ball end thereof contacts jack in moveable anchor disk ontology, and the other end is contacted with lower pressure ring, pushes
Ring surface has arc groove, and steel ball just moves in arc groove；Due to there is steel ball on moveable anchor disk ontology, just by script planar friction
Become rolling friction, rotated in jack convenient for moveable anchor disk ontology in this way and can be rotated with 360 °, facilitates moveable anchor and work
Make the alignment of anchor hole position.
