Abstract: A foldable stand includes two lower parts and two upper parts, the two lower parts are respectively and pivotably connected to the two upper parts by two plates located between the two lower parts. Each plate has two stops on two sides thereof so as to maintain the two lower parts at an angle. Each of the two upper parts has two protrusions which can be respectively in contact with the two lower parts to maintain the angle between the two upper parts. The two lower parts can be pivoted toward each other and the two upper parts can be pivoted and positioned on two outsides of the two lower parts.

Abstract: A structural improvement handy mixer includes a base having a pair of rear rollers, a pair of front pads, a pair of vertical bars on rear end connected to a transverse bar and pivoted to a pair of longitudinal bars which have their free end connected to a pair of hollow interior rectangular posts, a U-shaped rail slidably connected to the top of the posts with an adjustment device engaged therebetween, an operational mechanism on the rear portion of the base to operate a stirring bar at front side, a mixing barrel on the front portion of the base protected by a pair of guard railings and a sensor nearby a lid to control the operation of the operational mechanism.

Abstract: A saw blade angular adjustment device for a metal and wood cutting machine includes a rectangular working platform having a pair of symmetrically arranged triangular support arms on lateral sides each including a screw hole in the top engaged with an arcuate slit in the middle portion of a pair of pillow shaped pivotal plates which is rotatably secured to the arms by bolt, a pair of sliding bars parallel secured to the top of the pivotal plates, a saw blade angular adjustment assembly slidably engaged onto the sliding bars including a seat and a guarded saw bladed which is operated by a motor inside the seat a pair of first and second clamping plate parallel disposed on the front portion of the platform and a pair of U-shaped rods respectively inserted into the front and rear end of the platform.
