<p>PURPOSE: To lock and unlock an application mechanism by moving a lock in the longitudinal direction, rotating two semi-cylindrical pieces due to the slide of a projecting passing through the groove of a connection lever, and determining the fixation and release between two concentric bodies. CONSTITUTION: Each lock-locking point consists of a semi-cylindrical piece 2 for locking and a complementary semi-cylindrical piece 3 that complement each other, and they are accommodated in a corresponding hole 4 that is provided between an outer concentric body 5 and an inner concentric body 6 that can be combined to the fixed and movable parts of an application mechanism. The complementary semi-cylindrical piece 3 is independently free, and the semi- cylindrical piece 2 for locking can cooperate with a connection lever 1, can move a corresponding lock 8 in the longitudinal direction, and can be rotated by the slide of a projection 9 of the lock 8 passing through a spiral groove 7 of the connection lever 1. Then, the rotary attitude of the set of the two semi-cylindrical pieces 2 and 3 determines the fixation and release between the two concentric bodies 5 and 6, thus locking or releasing the application mechanism.</p> |
