Benefits of technology
The invention is a collapsible stand that has a simple structure, is easy to operate, and is highly safe and stable. The stand can be effortlessly collapsed by using a pedal, and it ensures a steady mounting of a processing tool when extended.
Problems solved by technology
This foldable worktable is functional; however, it is still not convenient for use because the legs of this foldable worktable are not equipped with rollers for convenient movement with the machine tool when the foldable worktable is folded up.
However, when in use, the stand must be converted to a position perpendicular to the floor in order to collapse the support legs; where due to the weight of the machine tool supported thereon it is much heavier than the stand itself.
Therefore, when biasing the stand, it is likely to be dangerous to the operator.

Embodiment Construction
[0018]Referring to the annexed drawings in detail, a collapsible stand 1 in accordance with the present invention is shown. For convenience of explanation, the following embodiment uses the rear end of the first stand leg 11 at which the rollers 17 are located as a directional reference (as shown in FIG. 1). As illustrated, the collapsible stand 1 comprises a support 10, a positioning unit 20, and a control unit 30.
[0019]Referring to FIG. 1 and FIG. 2, the support unit 10 comprises a first stand leg 11, a second stand leg 13 and a support arm set 15. The first stand leg 11 and the second stand leg 13 are crossed and pivotally connected with each other so that the first stand leg 11 and the second stand leg 13 are movable between an extended position and a folded position. The first stand leg 11 comprises a left leg shaft 111, a right leg shaft 112, and a front transverse bar 113 and a rear transverse bar 114 respectively and transversely connected between opposite front and rear end...

A collapsible stand mainly includes a support unit including two stand legs pivotally connected together in a crossed manner and a support arm set pivotally connected to one stand leg, a positioning unit including an abutment member and a bearing member respectively mounted at one stand leg and the support art set and so configured that when the collapsible is extended out or collapsed, the abutment member is engaged with a different part of the bearing member, and a control unit mounted at one stand leg and operable to bias the abutment member, moving the abutment member into engagement or away from the bearing member. Thus, the collapsible stand has a simple structure, facilitates operation and ensures a high level of operational safety and structural stability.
Description
BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to cutting tool stands, and more particularly to a collapsible stand.2. Description of the Related Art[0002]In order to facilitate delivery between different workplaces, machine tool stands for regular small-scale machine tools commonly have a folding design so that the stands can be alternatively set between an extended position and a folded position.[0003]Various machine tool stands are known. For example, Taiwan Patent I289101 teaches the use of a pedal to move four links, where these four links are forced to carry one respective wheel seat when lifting the base from the floor. The wheel seats must have enough structural strength so that the expected effects can be achieved. Further, U.S. Pat. No. 6,607,015 discloses a foldable worktable. This foldable worktable is functional; however, it is still not convenient for use because the legs of this foldable worktable are not equipped with rollers ...
