Abstract
The invention relates to a stabilizing and locating mechanism which comprises a base unit, a group frame unit, a stabilizing unit and a locating unit. The group frame unit is arranged on the base unit and stretches out and draws back between a containing position and a working position, the group frame unit comprises a pushing against part, the stabilizing unit is arranged on the base unit and comprises a movable carrying platform, and the movable carrying platform is provided with a locating part opposite to the group frame unit. The locating unit comprises a locating body arranged on the base unit, and the locating body is changed between a pressing against position and a releasing position relative to the movable carrying platform and constantly bears elastic restoring force towards the releasing position. When the group frame unit is arranged on the containing position, the pushing against part pushes against the locating body to the pressing against position to press against the locating part of the movable carrying platform. When the group frame unit is arranged on the working position, the locating body elastically resets to the releasing position to release the movable carrying platform, the mechanism is truly simplified, and noise is prevented.
