Abstract
A holding mechanism includes a stand, a frame, a first mechanism and a second mechanism. The frame is slidably disposed on the stand and has an engaging portion. The first mechanism is installed on a side of the stand and provides the frame with a first force. The second mechanism is installed on another side of the stand and opposite to the first mechanism, and the second mechanism is capable of switching between an engaging status and a released status. The second mechanism engages with the first mechanism as being in the engaging status, so as to be connected to the frame and provide the frame with a second force. The second mechanism separates from the first mechanism as being in the released status, so as not to be connected to the frame and not provide the frame with the second force.
