The first shell includes a sidewall with a first through hole. Each locking mechanism includes a chassis, a screw, a first coupling portion, and a second coupling portion. The first coupling portion defines a second through hole, the second coupling portion defines a third through hole. The first through hole can communicate with the second through hole and the third through hole. The screw passes through the third through hole and the second through hole to couple the first shell to the second shell. ## Claims ### Claim 1 An electronic device with concealed coupling member comprising: a housing comprising a first shell and a second shell, the first shell including a sidewall with a first through hole; and a coupling member comprising at least one locking mechanism; wherein the locking mechanism comprises a chassis having a first end and a second end, a screw received in the chassis, a first coupling portion positioned in the first shell and adjacent to the first end of the chassis, and a second coupling portion positioned on the second shell; the second end of the chassis is adjacent to the first through hole; the first coupling portion defines a second through hole; the second coupling portion defines a third through hole; the first through hole can communicate with the second through hole and the third through hole; the screw passes through the third through hole and the second through hole configured to couple the first shell to the second shell. ### Claim 2 (depends on 1) The electronic device with concealed coupling member as claimed in claim 1, wherein the chassis defines a receiving groove configured to receive the screw, the receiving groove corresponds to the first through hole. ### Claim 3 (depends on 2) The electronic device with concealed coupling member as claimed in claim 2, wherein the each of at least one locking mechanism further comprises a cover positioned on the chassis, the cover covers the receiving groove for prevent the screw deviating from the receiving groove. ### Claim 4 (depends on 2) The electronic device with concealed coupling member as claimed in claim 2, wherein the each of at least one locking mechanism further comprises a spring, the spring is coiled around the screw. ### Claim 5 (depends on 2) The electronic device with concealed coupling member as claimed in claim 2, wherein the spring is received in the receiving groove. ### Claim 6 (depends on 2) The electronic device with concealed coupling member as claimed in claim 2, wherein the screw comprises a rod portion, a head portion connected to the rod portion, and a groove defined on the head portion, one end of the rod portion defines a external thread. ### Claim 7 (depends on 6) The electronic device with concealed coupling member as claimed in claim 6, wherein the groove corresponds to the first through hole. ### Claim 8 (depends on 6) The electronic device with concealed coupling member as claimed in claim 6, wherein the diameter of the external thread is less than the diameter of the rod portion. ### Claim 9 (depends on 6) The electronic device with concealed coupling member as claimed in claim 6, wherein at least one of the second through hole and the third through hole defines an internal thread, the internal thread is engaged with the external thread. ### Claim 10 (depends on 1) The electronic device with concealed coupling member as claimed in claim 1, wherein the first shell further comprises a bottom plate and a flange positioned on the plurality of sidewalls. ### Claim 11 (depends on 10) The electronic device with concealed coupling member as claimed in claim 10, wherein the plurality of sidewalls are formed by extending vertically from sides of the bottom plate. ### Claim 12 (depends on 10) The electronic device with concealed coupling member as claimed in claim 10, wherein the coupling member further comprises at least one clasp and a latching mechanism, at least one clasp is engaged with the flange of the first shell. ### Claim 13 (depends on 12) The electronic device with concealed coupling member as claimed in claim 12, wherein the latching mechanism comprises a first latching member and a second latching member engaged with the first latching member. ### Claim 14 (depends on 13) The electronic device with concealed coupling member as claimed in claim 13, wherein the first latching member is positioned on at least one of the sidewalls. ### Claim 15 (depends on 13) The electronic device with concealed coupling member as claimed in claim 13, wherein the second latching member defines a latching hole, the first latching member is engaged with the latching hole.
