The keyboard element 3 and the keyboard protective cover 4 are respectively limited and fitted on the keyboard carrier plate 20 and the product protective shell partial carrier plate 22 through the contoured grooves. It can be seen that the keyboard carrier plate 20 supports and fixes the keyboard limit blocks 200 and the keyboard adjustable positioning blocks 201. The keyboard limit blocks 200 and the keyboard adjustable positioning blocks 201 are both hard limits, forming contoured grooves to limit the keyboard element 3. The keyboard adjustable positioning block 201 has an adjustable position, which can avoid processing errors that cause a gap between the keyboard and the limit or inability to insert.

[0018] like Figure 7As shown, in this embodiment, the propulsion structure 23 includes a first mounting block 230, a push handle block 231, and a second mounting block 232. The first mounting block 230 is limitedly matched on the rotating arm module 21. A pair of guide shafts 233 are arranged between the first mounting block 230 and the second mounting block 232. A linear bearing 234 is arranged on the push handle block 231. The push handle block 231 slides with the guide shaft 233 through the linear bearing 234.
