Abstract:
A fastener lock apparatus comprising:a fixed base mount member (1) provided with a bearing sleeve portion (2) and a front concave portion (8), wherein said front concave portion (8) is formed in a front surface of said fixed base mount member (1), and a bearing hole (34) is formed in a central portion of a bottom surface of said front concave portion (8)to communicate with the interior of said bearing sleeve portion (2) of said fixed base mount member (1); a locking shaft (3) mounted in said bearing sleeve portion (2) of said fixed base mount member (1) in an insertion manner so as to be axially and rotatably movable therein; a handle (4) having its proximal end portion connected with a front end portion of said locking shaft (3) through a pivot pin (5); a rotation angle limiting disc (10) rotatably received in said front concave portion (8) of said fixed base mount member (1), wherein said rotation angle limiting disc (10;) is provided with an eccentric protrusion (11) which is inserted into a fan-shaped concave portion (12) formed in said front concave portion (8) of said fixed base mount member (1); a spring member (14) for biasing said handle (4) toward a front surface portion of said rotation angle limiting disc (10); and a latching plate (6) fixedly mounted on said locking shaft (3); whereby when said latching plate (6) is in its fastened locking position, said proximal end portion of said handle (4) has its first abutting surface (15) abut against said rotation angle limiting disc (10); and, when said latching plate (6) is in its unfastened relief position, said proximal end portion of said handle (4) has its second abutting surface (16) abut against said rotation angle limiting disc (10), wherein a distance between said first abutting surface (15) and said pivot pin (5) is greater than a distance between said second abutting surface (16) and said pivot pin (5); said locking shaft (3) being provided with a rotation inhibiting shaft portion (17) which is fitted in a central through-hole (13) of said rotation angle limiting disc (10) to inhibit said disc (10) from rotating relative to said locking shaft (3); and said locking shaft (3) being further provided with a rotation permitting shaft portion (18) which is fitted in said central through-hole (13) of said rotation angle limiting disc (10) to permit said disc (10) to rotate relative to said locking shaft (3), wherein said locking shaft (3) has said rotation inhibiting,shaft portion (17) disposed adjacent to said permitting shaft portion (18).
