TL;DR: In this article, an ultrasonic wave handle of a knife can be used by direct mount in rotatory lathe equipment such as drilling machine, milling machine, digit control machine tool, machining center.

TL;DR: In this article, a gear hobbing and pinning tool capable of efficiently machining internal gears is described. But the tool is not suitable for high inefficiency, time-saving and labor-saving.

TL;DR: In this paper, the utility model discloses an automatic change special blade holder of handle of a knife, including the blade holder mechanism of base, the actuating mechanism who sets up at the base middle part, base upper portion both sides and used for connecting the drive mechanism of actuating and blade holder mechanisms, the mechanism is including setting up the two sets of gear trains inthe actuating both sides, the gear train includes intermeshing's action wheel and follows the driving wheel, actuating mechanisms passes through electromagnetic clutch and links to each other with the action wheel, set

TL;DR: In this paper, an ultrasonic wave handle of a knife ring transducer, including casing and the oscillator mechanism of setting in the casing, was shown to be convenient firm, avoids making the wire to drop from the electrode slice, prevents to cause the damage of transducers, the life of extension transducers.

TL;DR: In this article, a gauge for detecting external cones of knife handles is presented. Butts et al. used a bottom seat plate with plain glass, a horizontal display, and threaded connection with a fixed bolt vertical to the strut.
