In the present embodiment, each first limiting distance is smaller than a first combining length of each first screw 412. Each second spacing distance is less than the second coupling length of each second screw 422. In detail, when the housing 51 is combined with the panel 1, a distance between each limiting convex pillar 52 corresponding to each first screw head 411 and each corresponding first screw head 411 in the housing 51 is the first limiting distance, and a distance between each limiting convex pillar 52 corresponding to each second screw head 421 and each corresponding second screw head 421 is the second limiting distance. If each first screw 412 is influenced by external factors to move in a direction away from the corresponding first locking hole 121 and to link the corresponding first screw 412 to move in a direction away from the corresponding first locking hole 121, and when each first screw 411 abuts against the corresponding limiting convex column 52 while moving the first limiting distance, each first screw 411 cannot move continuously in a direction away from the corresponding first locking hole 121, and at this time, since each first limiting distance is smaller than the first coupling length of each first screw 412, the length of each first screw 412 locked in the corresponding first locking hole 121 is ensured to exceed the first coupling length, and each first screw 412 is effectively ensured not to be separated from the corresponding first locking hole 121.

And when each second screw 422 is affected by external factors, each second screw 422 moves in a direction away from the corresponding second locking hole 231, and when each second screw 421 abuts against the corresponding limiting convex pillar 52, each second screw 421 cannot move continuously in a direction away from the corresponding second locking hole 231, at this time, the length of each second screw 422 locked into the corresponding second locking hole 231 is greater than the second combination length, thereby effectively ensuring that each second screw 42 cannot be separated from the corresponding second locking hole 231.
In addition, in the embodiment, the first combination length of each first screw 412 is greater than one third of the length of each first screw 412, which is to say simply that each first screw 412 does not disengage from the corresponding first locking hole 121 when the length of each first screw 412 combined into the corresponding first locking hole 121 is greater than one third of the length of each first screw 412, but not limited thereto, and each first combination length required by practical considerations may be considered, but generally, the first combination length of each first screw 412 is at least greater than one third of the length of each first screw 412 and is less than one half of the length of each first screw 412, so as to ensure that each first screw 412 does not disengage from the corresponding first locking hole 121. The second coupling length of each second screw 422 is greater than one third of the length of each second screw 422, and in short, each second screw 422 will not disengage from the corresponding second locking hole 231 as long as the length of each second screw 422 coupled into the corresponding second locking hole 231 is greater than one third of the length of each second screw 422, but not limited thereto, and the required second coupling length can be considered according to practical situations, but generally, the second coupling length of each second screw 422 is at least greater than one third of the length of each second screw 422 and is less than one half of the length of each second screw 422, so as to ensure that each second screw 422 will not disengage from the corresponding second locking hole 231.
In summary, the electronic device for preventing the screw from loosening of the present invention is designed by extending the position-limiting protruding column 52 of the back cover 5 toward the corresponding first screw head 411 and toward the corresponding second screw head 421, and matching the position-limiting protruding column 52 of the corresponding first screw head 411 and the corresponding first screw head 411 to be away from the first position-limiting distance, and the position-limiting protruding column 52 of the corresponding second screw head 421 and the corresponding second screw head 421 to be away from the second position-limiting distance, and the first position-limiting distance is smaller than the first combination length of the first screw rod 412 and the second position-limiting distance is smaller than the second combination length of the second screw rod 422, so as to effectively ensure that the length of the corresponding first locking hole 121 into which the first screw rod 412 is locked is longer than the first combination length, and the first screw 41 will not be separated from the corresponding first locking hole 121, and the length of each second screw 422 locked into the corresponding second locking hole 231 is greater than the second combination length, so that each second screw 42 is not separated from the corresponding second locking hole 231.
