At the same time, when the locking component 10 exits the aforementioned engaging hole 302 along the second direction X, the slider 11 can provide a thrust along the first direction Z to the driving component 30 through the guide part 111, so that the driving component 30 rises for the next installation.

[0076] Please refer to Figure 7 The slider 11 also has a first surface 113 and a second surface 114 opposite to each other in a third direction Y, the guide portion 111 is arranged on the first surface 113, and / or the guide portion 111 is arranged on the second surface 114, and / or the guide portion 111 is arranged between the first surface 113 and the second surface 114, and the third direction Y intersects with both the first direction Z and the second direction X.

The elastic member 13 is suitable for elastic deformation in the second direction X. When the insertion rod 12 penetrates the positioning hole 411, the elastic member 13 is in a compressed state, so that when the second box body 300 moves away from the first box body 200, the second box body 300 begins to stop providing pressure to the driving component 30, and at the same time, the insertion rod 12 withdraws from the aforementioned clamping hole 302 under the push of the elastic member 13, and the locking effect of the locking component 10 on the second box body 300 is released, so that the second box body 300 can be detached from the first box body 200, and the disassembly is simple.
