The magnetic repulsion force between the magnetic elements 72 can drive the latch 68 to move back to the position shown in FIG. It will interfere with the latch 68 . Moreover, after the reset member 78 connected to the hook 64 is separated from the fourth hole 641 of the hook 64 after the latch 68 is separated, the hook 64 is driven on the guide post 62 in a direction opposite to the first direction (- Y direction) slide and withdraw from the first hole 581 of the first housing 58, the fifth hole 661 of the fixing member 66, and the third hole 601 of the second housing 60 for retracting into the second housing 60, In this way, the hook 64 can be protected from being damaged by impact and the aesthetic appearance of the overall appearance can be maintained. And the reset element 78 can be a spring, which means that when the hook 64 slides in the first direction (+Y direction), the reset element 78 is stretched, and when the latch 68 is separated from the fourth hole 641 of the hook 64 The restoring element 78 originally stretched in the first direction (+Y direction) will provide an elastic restoring force to the hook 64 for driving the hook 64 to slide in the -Y direction and return to the original position. The reset element 78 can be an optional configuration, that is, when the latch 68 is separated from the fourth hole 641 of the hook 64, the hook 64 can also slide in the -Y direction by its own gravity to return to the original position. , depending on the actual design requirements.

In addition, in order to realize the mechanism design of the double-sided latch host 52 and the screen 54, the first housing 58 is formed with a second hole 583 on the other side opposite to the first hole 581, and the fixing member 66 is opposite to the fifth The other side of the hole 661 is formed with a sixth hole 663, so that after the screen 52 is turned 180 degrees relative to the host 52, the hook 64 can pass through the third hole 601 of the second housing 60 and the first hole of the fixing member 66. The six holes 663 and the second hole 583 of the first housing 58 allow the end of the latch 68 to be inserted into the fourth hole 641 of the hook 64 for fixing the relative positions of the screen 52 and the host 54 . As shown in FIG. 10 , FIG. 10 is a schematic view of the internal structure of the latch member 68 latched on the other side of the hook 64 according to a preferred embodiment of the present invention. Same as the above-mentioned working principle, when the screen 52 is turned 180 degrees relative to the host 52 and the screen 54 gradually pivots to approach the host 52, the second housing 60 can be attracted by the first magnetic element 70 inside the first housing 58 The hook 64 inside, so that the hook 64 slides in the first direction (+Y direction) on the guide column 62, and passes through the third hole 601 of the second housing 60 and the sixth hole of the fixing member 66 663, and the second hole 583 of the first housing 58 are accommodated in the first housing 58, at the same time the first magnetic element 70 can drive the latch 68 close to the hook 64 and opposite to the second direction (+X direction), so that the end of the latch 68 is inserted into the fourth hole 641 of the hook 64 for fixing the relative position of the screen 54 and the host 52, and its working principle is the same as that of the previous embodiment , so it will not be described in detail here.
