Abstract: A drug injection device contains a needle holder, an ejector, a needle member, and an actuation assembly. The needle holder defines a drug delivery direction extending toward the injection end. The ejector contains a fixing segment that is fixed to the needle holder and located in the drug delivery direction, and the abutting segment extending toward the injection end and protruding beyond the needle holder. The needle member is movably arranged relative to the needle holder and contains a needle shaft connected to a needle hub coaxially arranged with the ejector for the abutting segment inserting into the needle shaft. The actuator assembly connects the needle holder and the needle shaft for driving the needle member between a first position and a second position with respect to the needle holder.

Abstract: A lamp shade structure refers to a design of a multi-layer shade. A top and a bottom end of the shade is provided respectively with a positioning ring, at least one layer of rigid member in a shape of mesh grids wraps around between the two positioning rings, and the positioning ring at the bottom end is connected inward with an assembly board to assemble a lamp. Each spaced mesh grid on the rigid member in the shape of mesh grids is enclosed by an enclosing member. When the shade is sheathed on the lamp, light released from a bulb will be transmitted out through the mesh grids that are spaced on the shade, thereby constituting an effect of explicit light scales.
