As the first substrate unit 22 rotates upward, the first outer guide group 35 slides as described above, causing the first clamping block 472 to compress the first elastic members 473 to allow the first clamping The end portion 4724 can move to the first outer guide plane portion 3581, and move along the first outer guide plane portion 3581 to the first outer rear guide slope portion 3582B in the folded state, when the first card When the control end 4724 abuts against the first outer rear guide inclined surface 3582B, the user must also overcome the frictional force provided by the first outer rear guide inclined surface 3582B to the first clamping end 4724 and the Only after the elastic force of the first elastic member 473 can the first substrate unit 22 be moved back to the flat state. In contrast, the operation of the second locking unit 48 is the same as that of the first locking unit 47, so it will not be elaborated one by one.

Of course, the number of the first inner guides 31 and the second inner guides 32 can be adjusted according to the stability of the actual sliding of the first moving member 33 and the second moving member 34, but, A first inner guide member 31 and a second inner guide member 32 can also be sleeved on the first movable member 33 and the second movable member 34, respectively, so that the first movable member 33 and the first movable member 33 The second moving member 34 slips.
