Dual-purpose grinder for seasoning

A dual-purpose grinder for seasoning, comprising

• two grinding mechanisms;
• each grinding mechanism including a shaft, an inner grinding wheel securely connected to the shaft, and an outer grinding wheel around the inner grinding wheel;
• two transmission mechanisms;
• two containing parts joined together at first ends thereof;
• each containing part holding a respective grinding mechanism in a second end thereof;
• each containing part holding a respective transmission mechanism in the first end thereof;
• the outer grinding wheels of the grinding mechanisms being secured in the respective containing parts;
• each containing part having a holding room between the grinding mechanism and the transmission mechanism for holding seasoning therein;
• each transmission mechanism including:
• (a) a single-directional ratchet securely connected to a corresponding shaft of the grinding mechanisms;
• (b) a separating unit securely held in a respective containing part;
• the separating unit having a hole thereon;
• the single-directional ratchet being tumably connected to the separating unit;
• (c) an actuating pinion passed through the hole of the separating unit;
• the actuating pinion being engaged with the single-directional ratchet at a first end thereof;
• and
• (d) a linearly displaceable member;
• the linearly displaceable member having a rack portion engaging a second end of the actuating pinion;
• the linearly displaceable member projecting out from a respective containing part at a second end thereof;
• the linearly displaceable member having a pressing portion;
• a separating member;
• the separating member being positioned between the linearly displaceable members of both of the transmission-mechanisms;
• the separating member being securely connected to the separating units of both of the transmission mechanisms;
• the actuating pinions of both the transmission mechanisms being tumably connected to the separating member at the second ends thereof;
• the separating member having a holding tunnel holding an elastic element therein;
• the separating member having two slots communicating with the holding tunnel and facing opposite directions;
• the linearly displaceable members being passed into first and second ends of the holding tunnel of the separating member respectively at the pressing portions thereof so as to touch two ends of the elastic element at the pressing portions;
• and
• two lateral pressed members;
• the lateral pressed members being connected to the coupled containing parts and facing in opposite directions;
• the lateral pressed members being connected to the second ends of the linearly displaceable members respectively at inward sides thereof.
