PatPat / PatPat

Pat Pat is an unconscious hunchback correcting device. It mimics the pat on the back of the person, reminds the other person of the hunchback, and the humpback person will sit up straight. Its principle is: when a person is hunchback, it drives the instrument monitoring part to bend, connect the power supply, and the instrument produces the vibration of "taking a beat" to remind him of his hunchback. After a period of time, the hunchback man had a sense of sitting straight to rectify his hunchback.
