Driller retaining device able to be positioned with well horizontality and verticality

Abstract

A driller retaining device able to be positioned with well horizontality and verticality includes a hollow outer sleeve having two end, one is a working end and the other being an assembly end; an inner wall of the assembly end being formed with a plurality of axial sliding tracks; an inner hollow cylinder arranged within the sleeve; two ends of the inner hollow cylinder being an machine end and an assembly end; an outer wall of the inner hollow cylinder having at least one sliding block which is arranged corresponding to the axial sliding groove. In in assembly, the inner hollow cylinder is combined to the driller; then the assembly end of the inner hollow cylinder is assembled to the assembly end of the outer sleeve; and at the same time, the sliding block of the inner hollow cylinder is assembled into the axial sliding groove of the outer sleeve.

What is claimed is: 
     
         1 . A driller retaining device able to be positioned with well horizontality and verticality; comprising:
 a hollow outer sleeve having two end, one being a working end and the other being an assembly end; an inner wall of the assembly end being formed with a plurality of axial sliding tracks;   an inner hollow cylinder arranged within the sleeve; two ends of the inner hollow cylinder being an machine end and an assembly end; an outer wall of the inner hollow cylinder having at least one sliding block which is arranged corresponding to the axial sliding groove of the outer sleeve;   wherein in assembly, the inner hollow cylinder is combined to the driller; then the assembly end of the inner hollow cylinder is assembled to the assembly end of the outer sleeve; and at the same time, the sliding block of the inner hollow cylinder is assembled into the axial sliding groove of the outer sleeve.   
     
     
         2 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein the inner hollow cylinder has a retaining unit for retaining a driller inserting to an inner space of the inner hollow cylinder so as to combine the driller to the inner hollow cylinder; the driller retaining unit includes a locking screw and a rubber friction end for retaining the inner hollow cylinder to the driller; the locking screw penetrates through a screw hole of the inner hollow cylinder, while the screw head exposed out of the inner hollow cylinder and the friction end is within the inner hollow cylinder. 
     
     
         3 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein the outer sleeve has at least one adjusting hole which axially penetrates through the wall of the outer sleeve; each adjusting hole is installed with an adjusting screw; a head of the screw is at the end of the assembly end of the outer sleeve and a distal end of the screw exposes out of the working end; in working, the working end of the outer sleeve resists against a working surface. 
     
     
         4 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein the outer sleeve is made of transparent material or partially transparent material. 
     
     
         5 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein a rubber ring is installed at the working end of the outer sleeve so that the working end of the outer sleeve can be tightly adhered to the working surface. 
     
     
         6 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein an outer wall of the outer sleeve is installed with a level meter. 
     
     
         7 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 1 , wherein an outer wall of the outer sleeve is installed with two level meters which are perpendicular to one another so that the outer sleeve can be installed at a horizontal direction or a vertical direction. 
     
     
         8 . The driller retaining device able to be positioned with well horizontality and verticality as claimed in  claim 3 , wherein a distal end of the adjusting screw is enclosed by a rubber so as to provide a desired friction.
