Patent ID: 8459091

Claim:
Test device for screwers, comprising a transducer ( 11 ) having a body and a head ( 28 ) with a seat ( 19 ) for receiving the coupling end ( 13 ) of an adapter or joint simulator ( 12 , 12 ′), said adapter or joint simulator ( 12 , 12 ′) having at an end opposite to said coupling end ( 13 ) of said adapter or joint simulator ( 12 , 12 ′) a working end ( 14 ) intended for coupling with a screwer to be tested, characterized in that said coupling end ( 13 ) is made with side wall ( 21 , 21 ′) polygonally-fashioned in order to be received in said seat ( 19 ), which has a complementary polygonal shape to said coupling end ( 13 ) of the adaptor or joint simulator ( 12 , 12 ′), said head ( 28 ) being adapted to be tightenable as a clamp in order to releasably lock, said coupling end ( 13 ) of the adapter or joint simulator in said seat ( 19 ) wherein said coupling end ( 13 ) has a cylindrical part ( 26 or 26 ′) that axially projects from said adapter or joint simulator ( 12 , 12 ′) which is adapted to be inserted in a complementary seat ( 27 ) on the bottom of said seat ( 19 ) of the transducer ( 11 ) in order to align said transducer ( 11 ) and said adapter or joint simulator ( 12 , 12 ′).
