Screw rod-type nut sheller

螺杆式坚果开壳器

Abstract

The utility model relates to a screw rod-type nut sheller. The nut sheller comprises a base body, a screw nut and a screw rod , wherein the base body is used for placing a nut; the base body and the screw nut are fixed in a opposite manner and arranged with in such a manner that a proper distance is formed between the base body and the screw nut; the screw rod is arranged in the screw nut; an internal threaded belt and a first non-threaded belt that extend in the axial direction are arranged on the internal cylindrical surface of the screw nut; an external threaded belt and a second non-threaded belt that extend in the axial direction are arranged on the external cylindrical surface of the screw rod; the width of the external threaded belt can be matched with that of the first non-threaded belt; the external threaded belt can be meshed with the internal threaded belt; the large diameter of the threads on the external threaded belt is smaller than the internal diameter of the first non-threaded belt; the width of the second non-threaded belt is matched with that of the internal threaded belt; and the external diameter of the second non-threaded belt is smaller than the small diameter of the threads on the internal threaded belt. When the screw rod rotates relative to the screw nut to a proper position, the screw rod and the screw nut are not meshed with each other, that is to say, the screw rod can be moved fast in the axial direction so as to be propped against the nut or moved away from the nut.
本实用新型涉及一种螺杆式坚果开壳器,包括用于放置坚果的座体、与座体相对固定且相距适当距离设置的螺母及设于螺母中的螺杆,螺母内柱面上设有均沿轴向延伸的内螺纹带及第一非螺纹带,而螺杆外柱面上设有均沿轴向延伸的外螺纹带及第二非螺纹带,外螺纹带宽度与第一非螺纹带相匹配并能与内螺纹带啮合且外螺纹带上的螺纹大径小于第一非螺纹带的内径,而第二非螺纹带的宽度与内螺纹带相匹配且第二非螺纹带的外径小于内螺纹带上的螺纹小径。本实用新型在当将螺杆相对螺母旋转至适当位置时,螺杆和螺母之间并无啮合关系,即可沿轴向快速移动螺杆,而更快地抵压住坚果或从坚果上移开。
