The column member for an elevating device has a body, a channel, an opening and an internal thread. The channel is formed through the body. The opening is formed in a front surface of the body and is in communication with the channel. The width of the opening is shorter than the diameter of the channel. The internal thread is formed on an inner surface of the channel. A rotating member is located in the channel and meshes the internal thread of the channel. The diameter of the rotating member is longer than the width of the opening to prevent the rotating member from coming off the column member via the opening. The column member easily holds the rotating member without any sliding elements, and the combination of the column member and the rotating member is safe.
