Mechanical locking and rotating device also known as twister, consisting of three elements coaxially connected one inside the other, by means of plugs and interpenetrating screws in slots formed on the cylindrical surfaces of the elements, in which a first upper element is used to maneuver the device, a second central element used to rotate the lining tube and a third element deputy to the connection of the end of the lining tube. 1. Locking and rotating device also known as twister , for tubular casing elements , in particular lining pipes , consisting of a completely mechanical locking and rotating structure with automatic and I or manual operation and characterized in that it is made in three cylindrical components with a circular section , coaxial in one another , and in which:{'b': 1', '2', '3', '4', '5', '6', '7', '3', '4', '5', '10', '9', '1, 'a) the upper cylindrical element () is provided on its circumferential surface with circular holes () and below with a collar () on which four seats covered by a flange () are formed within which are go to insert themself the pins () each conformed with a polygonal section with rounded corners and a circular head (), held in place by screws (); the collar () is provided with two other seats (′), and within each of which, in the same way, is goes to insert itself a pin (′), until to intercept the slot (), with a quadrangular opening, of the cylindrical element () when it is placed inside and coaxial with the element ();'}{'b': 9', '8', '10', '15', '16', '17', '17', '18', '19', '9, 'b) the central cylindrical element (), has four rectangular slots () and two quadrangular slots () on its circumferential surface, and inferiorly a collar (), with four seats () for pins (); the endeds of pins () intercept and fit into the circumferential channel (), located on the lower cylindrical element (), when it is inside and coaxial with the cylindrical element ();'}{'b': 19', '21', '22', '23', '23', '5', '18', '35', '24', '25', '26', ...
