A device is provided to apply fastening means (C) each provided at least with one almost flat head (H) having a central pass through hole (P) were two opposed sides (S) of said head have respective protrusions (J) at least approximately perpendicular in respect to the head (H) and forming shoulders (S).The remaining opposed sides of the head have respective tongues (L) jutting out of the head (H). Said device (1) comprises a first magazine (3) for nails (N) each assigned to block a fastening means (C) and it comprises a shooting means (5) assigned to shoot the nails (N) in a shooting direction for blocking the respective fastening means (C) through said hole (P). Said device (1) comprises a second magazine (9) having slide guide means (11) assigned house in a sliding manner a set of fastening means (C) with the tongues (L) oriented in the forward sliding direction (A) and the shoulders (S) being oriented transversally and toward the sliding direction provided to the fastening means (C) by pushing means (13) of the second magazine (9) towards an outlet end (15) of the second magazine (9). Said outlet end (15) has a pair of jaw means (17) hinged to respective first rotation pins (23) perpendicular oriented in respect to said sliding direction (A), said jaw means (17) are mutually faced and their front portions, in respect to the sliding direction (A), are elastically and mutually approached by means of respective elastic elements (21). Said front portions of the jaw means (17) fully protrude from the second store (9) toward said sliding direction (A), each of said jaw means (17) has at least a tooth (19) shaped in form of shoulder oriented towards the second magazine (9) and said tooth (19) is assigned to elastically match at least with a shoulder (S) of a fastening means (C) interposed between the jaw means (17). Said teeth (19) elastically and detachably hold the fastening means (C) in a position of alignment of the respective pass through hole (P) with the shooting direction of the shooting means (5). |
