Abstract: A folding tool stand includes a platform connected to a base frame. The platform is pivotally and slidingly connected at a first side thereof to the base frame and is pivotally connected at a second side thereof to links that are pivotally connected to the base frame. A leg support is pivotally connected to the base frame. A locking device is provided to maintain the platform in an extended position. In the collapsed position, the platform is guided by the links to be positioned along the base frame. In the extended position, the links guide and support the platform in a position spaced from the base frame. In an alternate embodiment, a driving device is used to provide support to the second side of the platform during expanding and collapsing of the folding tool stand.

Abstract: A positioning device for a turnable table of a saw machine having a pivot shaft that pivotally connects a pair of clamping units. A pressing member with an attachment portion for attaching to a coupling unit may be formed on each clamping unit. By manipulating a trigger of the coupling unit, the pair of clamping units can be driven to rotate a pair of corresponding clench members for selectively clamping or unclamping a base of the saw machine. Thereby, the turnable table can be secured in place upon adjustment.

Abstract: An adjustment device for an auxiliary fence includes a support frame, an auxiliary fence, a guiding unit and an adjusting unit. The guiding unit guides the auxiliary fence along a longitudinal direction such that the auxiliary fence is selectively slidable relative to the support frame. The adjusting unit allows the auxiliary fence to be adjusted relative to the support frame and securely positioned. The adjusting unit includes a driving member, a securing member installed on the driving member, and an elastomeric element. When the driving member is operated, the securing member becomes disengaged from the support frame which allows the position of the auxiliary fence to be adjusted by sliding it relative to the support frame.
