' *定(2) For the locked state of the second casing, please refer to the third _ time reference (4) - Fig.), the schematic diagram of the casing fixing device in the second casing is locked, and the above state is continued. The lower button device 1G=pieces=1b the first protruding end 13 is pushed into the lower casing 70=the second holding in the groove 16 of the extending arms 14, 15 is pushed away from the first The recess 31' maintains the second fixing piece 5A at a distance from the first U 40 to form an untwisted state.疋片(3) For the unlocking state of the first casing, please refer to (4), (5) Time (4) and 1), which is the schematic diagram of the casing fixing device of the embodiment in the unlocking state of the first casing, following the above action, pressing the button device The moment of the ig circle ^ button 11, while rotating the rotating device 2G counterclockwise, - the second locking flange 51 of the fixing piece 50 is separated from the first concave type = lock, and the protruding portion of the flange 51 will be fixed against The mechanism buckles: the fixing piece 50 is maintained at a distance from the fixing mechanism 3, and the circular button button 1G of the following button device 1G is in a state of being pressed without being applied with force, and at the same time, the rotating skirt is placed 2〇^ In the unlocked state, when the rotating device 2G can be rotated in winter alone = the twisting device 20, the first fixing piece 4 and the second fixing body can be rotated until the positioning flange 42 of the first fixing piece 40 touches the small ^ The second stop portion 34 of the mechanism 3 or the drop-shaped rotary button 21 has its large end facing upward, and the circular button U depressed at this time has not yet bounced back. 13 1268132 (4) The second casing unlocking state, please refer to the fifth figure (see also the first figure), which is a schematic diagram of the relevant components of the casing fixing device of the preferred embodiment of the present invention in the unlocking state of the second casing, and continues In this case, the second lock-and-flange 51 of the second fixing piece 50 is rebounded into the second groove-32 by the elastic force of the button spring 12, so that the second fixing piece 50 is in close contact with the first fixing piece 40. At the same time, the circular button 11 of the button device 10 is ejected, and the first locking flange 41 is offset from the blocking piece 60, and at this time, the casing is unlocked. • When the casing fixing device 1 is in the unlocked state of the second casing, returning to the original first casing locked state in a reverse operation manner, first pressing the circular button 11 of the button device 10, the first protruding The end 13 is pushed into the lower casing 70, and the strap pushes the second fixing piece 50 of the groove 16 clamped on the extending arms 14 and 15 out of the second recess 32, so that the second fixing piece is 50 and the second A fixing piece 40 is maintained at a distance to form an unwrapped state, and the rotating device 20 is rotated clockwise until the positioning flange 42 of the first fixing piece 40 touches the first stopping portion 33 of the fixing mechanism 30, and the second fixing piece The second locking flange 51 of the 50 spring is rebounded into the first recess 31 by the elastic force of the button spring 12, so that the second fixing piece 50 is in close contact with the first fixing piece 40, and the circular button 11 of the button device 10 When the first locking flange 41 is blocked, the blocking piece 60 is blocked, and the first casing is locked back. In summary, the design of the present invention utilizes a casing button rotation fixing mechanism to lock and unlock the casing generated by the double operation of the button and the rotary button, thereby achieving a manner of fixing the casing by using a screw. And the horizontal dial type fixing method can provide a kind of casing locking and fixing device which is simple, inexpensive and stable without the need of screws in the case of computer assembly 1268132 test, general debugging repair or hardware replacement. The case can be modified by people who are familiar with the technology, but they are all protected by the scope of the patent application.
