A rapidly collapsible stand includes a base frame, a pair of pivot members pivotally connected to a first side of the base frame, a first supporting frame connected to the pivot members, a first supporting unit pivotally connected between the base frame and the first supporting frame, a second supporting frame pivotally connected to the first supporting frame and a second supporting unit pivotally connected between the base frame and the second supporting frame. When operating the base frame, the second supporting frame is able to be extended away from the first supporting frame to an extended position by utilizing the linkage of the first supporting unit and the second supporting unit; or the second supporting frame is able to be received toward the first supporting frame to a received position by lifting up a handle portion of the first supporting frame. |

1. A rapidly collapsible stand comprising:
a base frame adapted for supporting a machine tool, the base frame having a first lateral portion and a second lateral portion respectively located on opposite sides of the base frame; first and second pivot members pivotally disposed on the first lateral portion; a first supporting frame including first and second first legs pivotally engaging with the first and second pivot members, respectively, and a bottom bracket disposed between the two first legs; a first supporting unit pivotally disposed between the second lateral portion of the base frame and the first supporting frame; a second supporting frame including first and second second legs pivotally coupled to the first and second first legs, respectively, each of the second legs defining an end section oppositely positioned relative to the bottom bracket of the first supporting frame; and a second supporting unit for positioning the second supporting frame relative to the first supporting frame and pivotally coupled to said pivot members and said second legs; wherein, in an extended configuration, the first supporting frame and the second supporting frame are positioned outwardly away from each other such that the bottom bracket of the first supporting frame and the end sections of the second supporting frame are generally located at their farthest distance apart, the second supporting unit securely positioning the second supporting frame relative to the first supporting frame; wherein, in a folding configuration, the first supporting frame and the second supporting frame are oriented substantially parallel toward each other, the base frame is arranged substantially upright such that the second lateral portion of the base frame is located adjacent to the first supporting frame. |
