Abstract: Method and down-hole tool for use inside a well, the down-hole tool including a housing; an anchoring arm rotatably attached to the housing and configured to move between an open position and a closed position; a spring block configured to have a central part that moves along a longitudinal axis (X) of the housing which results in the movement of the anchoring arm between the open or closed positions; and an actuating mechanism connected to the central part and configured to move the central part along the longitudinal axis. The spring block is detachably attached to the housing.
