Abstract: A shank retaining base for a screwdriver comprises a handle, a shank body, and a base mount wherein the handle has a receiving cavity disposed the center thereof for the base mount to be adapted therein, and the base mount has a polygonal sleeve hole and a round pivot hole disposed at both ends thereof for the shank body, a polygonal rod with tool heads of different sizes disposed at both ends thereof, to be sleeve joined therein. The base mount also includes a journal section with a roller bead embedded at the upper section and a flexible means covering the outer side thereof disposed at the middle section thereof. Via a circular guide facet and equidistant retaining ribs with oblique guide edges disposed at one side of the journal section thereof, the base mount is straightly guided and smoothly pushed with pressure to the receiving cavity therein, preventing the bottom side of the handle from getting cracked or broken up in assembly.

Abstract: A safety door barrier includes a barrier post, barrier body, and a barrier stopper. The barrier post has upper and lower seats at the upper and lower ends thereof respectively. The upper seat has an upper stop with an upwardly slanted bottom and a lower stop with a downwardly slanted top. The lower stop has a lower stop hole, and the lower seat has a lower seat hole. The barrier body has an upper projection and a lower projection corresponding to the lower stop and the lower seat respectively, an upper pivot and a lower pivot extending downwardly from the upper and the lower projections respectively corresponding to the lower stop hole and the lower seat hole, and a latch device composed of a latch and a spring disposed at a lateral side of the barrier body opposite to the upper projection. The barrier stopper provides a latch hole corresponding to the latch device. The barrier body can be raised up and pushed forward or backward to open.
