[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to supplement the specific locking method when the device housing 101 and the mounting back plate 201 are closed to each other in the first embodiment, and the specific unfolding method when the device housing 101 and the mounting back plate 201 are unlocked.

[0032] like Figure 2-4 As shown, in this embodiment, a mainboard mounting seat 105 is fixedly installed at the four corners of the device housing 101, and the mainboard mounting seat 105 and the four corners of the device mainboard 106 are mutually clamped, and fastening bolts 107 are inserted and installed at the four corners of the device mainboard 106; the upper edges of both sides of the mounting back plate 201 are fixedly installed with mounting screws 203 by bolts, and the mounting screws 203 are fixedly installed on the upper and lower sides of the No. 1 base 202, and a No. 1 connecting rod 204 is hinged on one side of the No. 1 base 202, and a No. 2 connecting rod 205 is hinged at the lower end of the No. 1 connecting rod 204, and the No. 2 connecting rod 205 is hinged at the lower end.
