Abstract:
A universal setting tool for use in connection with the insertion and fixation of different anchors within bores preformed within a substrate, comprising:a collet housing defining an axis around which said collet housing is capable of being rotated; a shaft integrally fixed upon a first end of said collet housing for insertion within a chuck mechanism of a rotary drive tool such that when said shaft is fixedly secured within the chuck mechanism of the rotary tool, and the chuck mechanism of the rotary tool is rotated, said collet housing will be rotated around said axis; a first bore extending axially inwardly from a second end of said collet housing and defined by means of an inner peripheral wall wherein said first bore comprises an open space across its diametrical extent; and radially expansible and contractible means disposed within said open space of said first bore of said collet housing so as to be free to contract radially inwardly in a substantially unrestricted manner to variable extents within said open space of said first bore of said collet housing so as to render said setting tool capable of gripping different anchors having different diametrical extents when an anchor is inserted into said first bore of said collet housing and said collet housing is rotated in a first direction around said axis of said collet housing, and for expanding radially outwardly within said open space of said first bore of said collet housing when said collet housing is rotated in a second opposite direction around said axis of said collet housing so as to be capable of releasing an anchor previously inserted into said first bore of said collet housing and fixedly gripped by said radially expansible and contractible means as a result of said radially expansible and contractible means having been radially contracted in response to said collet housing having been rotated in said first direction around said axis of said collet housing.
