High-strength anti-falling POS machine shell

The utility model discloses a high-strength anti-falling POS machine shell, relates to the technical field of POS machine shells, and aims to solve the problems that in an existing POS machine, an internal circuit board is directly, rigidly and fixedly connected to the interior of a machine shell through screws, and after the POS machine falls, impact force is directly transmitted to the internal circuit board through the machine shell and the screws; and the internal circuit board is damaged due to strong impact. A circuit board is arranged in the POS machine outer shell; the POS machine further comprises connecting plates which are fixedly arranged at the four corners of the circuit board, the lower ends of the connecting plates are fixedly connected to the upper ends of spring damping shock absorbers, the lower ends of the spring damping shock absorbers are fixedly connected to positioning blocks, and the positioning blocks are fixedly connected to the inner surface of an outer shell of the POS machine.
