In traffic accidents, the handle cannot be pulled open, and the rescue is delayed. Therefore, the semi-concealed handle not only has low cost, but also does not delay the rescue. The unlocking mechanism is also arranged on the semi-concealed handle. The handle body is pulled, and the thumb is pressed on the unlocking button of the handle body, so that the door can be pulled open. According to the Chinese utility model patent with application No. 2021207943581, the micro-motion button is arranged on the upward handle, and the micro-motion switch is arranged on the fixed handle seat. In the normal state, the micro-motion button is separated from the micro-motion switch. When the micro-motion button is pressed, the micro-motion button presses the contact of the micro-motion switch, and the unlocking or locking of the door is realized. Compared with the unlocking mechanism with only the micro-motion switch, the above-mentioned handle has a micro-motion button. The micro-motion button is connected to the upward handle in a compression spring structure. When the micro-motion button is pressed, the torsional spring is compressed. When the micro-motion button is released, the torsional spring restores the micro-motion button to the original position. The micro-motion switch is arranged on the handle seat. The handle body needs to be swung, and the distance between the micro-motion button and the contact of the micro-motion switch needs to be controlled. The product precision is high, and the micro-motion switch is easily damaged or misused after long-term use. CONTENT OF THE UTILITY MODEL
