Abstract: An automatic-alignment load-detection apparatus includes: a drawing die, an adapter ring, a tapered spacer and a force sensor. An automatic-alignment load-detection method includes steps of: providing an automatic-alignment load-detection apparatus used for a wire drawing machine, and applying a pulling force, to enable a wire to pass through the drawing die, the adapter ring, the tapered spacer and the force sensor. At the same time when the wire is being pulled, the wire can pass through the drawing die and rub against the drawing die, to enable the drawing die to apply a force on the adapter ring, the tapered spacer, and the force sensor, so as to further enable the force sensor to detect an axial-direction load, so that a wear degree of the drawing die can be detected in real time by using the axial-direction load, and the quality of a wire can be determined in real time.

Abstract: A resistance feedback laryngoscope contains a pushing grip, a trigger pad, a rotary shaft, a first transmitting rod, a second transmitting rod, and a two-step levering blade. The pushing grip includes a curved front side connecting with the two-step levering blade. The two-step levering blade includes a first movable blade, a second movable blade, and a fixed blade. The first transmitting rod and the second transmitting rod connect with the rotary shaft fixed on a drive post with a resilient element. The resilient element has a first foot butting against a locking peg proximate to the drive post and has a second foot being biased against a side piece of the rotary shaft. The trigger pad contacts with the pushing grip and curves upward slightly, and the trigger pad includes an arcuate groove formed therein, a bottom end of the arcuate groove contacts with the side piece of the rotary shaft.
