Fruit peeling machine

A fruit peeling machine comprising:

• a base;
• a transmission rod mounted rotatably and slidably on said base such that said transmission rod can be actuated by an external force to displace along the direction of a longitudinal axis of said transmission rod, said transmission rod provided with a first spiral slot and a second spiral slot different in guide range from said first spiral slot so as to form on said transmission rod a meeting place and a separating place which is separated from said meeting place by a distance;
• an engagement device mounted on said base and comprising a first engaging member having two engaging teeth which are engageable with said first spiral slot, and a second engaging member having two engaging teeth which are engageable with said second spiral slot;
• a fruit fastening member fastened with one end of said transmission rod for holding securely a fruit to be peeled;
• and
• a peeling tool mounted on said base for peeling the fruit held by said fruit fastening member;
• wherein said transmission rod is actuated by the external force to rotate such that said transmission rod displaces along the direction of the longitudinal axis thereof to actuate the fruit held by said fruit fastening member to move linearly and rotate, at the time when said first engaging member is engaged with said first spiral slot, or when said second engaging member is engaged with said second spiral slot;
• and
• wherein a ratio is formed by a quantity of an axial displacement of said transmission rod and a number of rotation of said transmission rod at such time when said first engaging member is engaged with said first spiral slot, said ratio being different from a ratio formed by a quantity of an axial displacement of said transmission rod and a number of rotation of said transmission rod at such time when said second engaging member is engaged with said second spiral slot.
