When it is in the locked state (as shown in Figs. 3 and 4), one end of the control lock (30) is protruded by the slide hole (24) of the rotary fastener (20), and the extension is located at the fixed position. The groove (15) is used to fix the rotating fastener (20) and the fixed shell ^ (ίο). Therefore, when the fixed casing (10) is fixedly combined with the cabinet body, the fastener (20) can be rotated ) (26) to lock the cabinet door or the cover of the cabinet, when you want to open (as shown in Figures 5 and 6), and insert the key 40 (23) with the key 40, The key (40) pushes the opening inclined surface (32) of the control lock (30) with the inclined surface (41) at the end, so that the control lock (30) projects into the end of the fixing groove (15). Push back, so that the other end protrudes from the movable groove (16), so that the rotary fastener (20) can be rotated in the movable groove (16), and at the same time, the buckle piece (26) is rotated to open at the same time, to reach the opening Purpose, and at this time, the other end of the control lock (30) is pushed back to be fixed, and at the same time, the tooth portion (42) of the key (40) will fall into the accommodation groove (30) of the control lock (30) ( 33), so the key (40) at this time has no issue key The key socket (23) is pulled out (not shown in Figures 7 and 8), and when the key (40) turns the rotary fastener (20) back to the square direction of the lock, the lock is controlled at this time The other end of (30) is at the fixed slot (15), so that the control lock (30) has space to move, so the key (40) can be pulled out, and the key court (40) is pulled out with teeth. The shape part pushes the outside of the accommodation groove (33), and closes the inclined pushing surface (34), so that the control lock (30) is pushed back to the other side, so that the key (40) has enough space to withdraw and control the lock (30) The pushed back end extends into the fixing groove (15) again, so that it can be fixed again.
