Abstract:
1. A mobile tool stand comprising: a base frame unit having a first end part, a second end part opposed to the first end part, and a middle part positioned therebetween; a support unit connected to the base frame unit and adapted for supporting the base frame unit; and a carrier unit mounted on the base frame unit and having a carrier plate, a pair of fixed-length links pivotally connected to two corners of a first lateral side of the carrier plate and to the middle part of the base frame unit, and a pair of coupling rods pivotally connected to two corners of a second lateral side of the carrier plate, and telescopically coupled to the second end part of the base frame unit such that the second lateral side of the carrier plate is both freely pivotable and axially slidable relative to the base frame unit; wherein each link includes a first end pivotally connected to the base frame unit at the middle part thereof, and a second end opposed to the first end and pivotally connected to two corners of the first lateral side of the carrier plate, and the second ends of the links are movable between a collapsed position, where the second ends of the links are maintained in proximity to the base frame unit, and an extended position, where the second ends of the links are spaced from the base frame unit, and the coupling rods are moved relative to the second end part of the base frame unit when the links are moved between the collapsed position and the extended position; wherein when the mobile tool stand is collapsed, the links are forced to move the carrier plate toward the base frame unit and the carrier plate is forced to move the coupling rods axially relative to the base frame unit in order to lower the center of gravity of the mobile tool stand, and then the support unit can be set in a collapsed position.
