The use method of the portable fruit picker comprises the steps that when the portable fruit picker is used, an iron wire 1-3 penetrates through an iron wire guide rail 1-2, and the lower end of the iron wire 1-3 is wound and knotted and fixed on a positioning pin on the inner wall of a handle fixing ring 5; then the handle 13 is rotated to separate the compression roller 11 from the compression groove 3-2, the buffering cylinder 3-1 is pulled out from the picking cylinder 1-1 (before being used, the buffering cylinder 3-1 is defaulted to be sleeved inside the picking cylinder 1-1), the picking clamp 2 is in a closed state (see figure 6) when no force is applied, when picking is required, the handle 6 is pulled downwards by hand, the handle fixing ring 5 drives the iron wire 1-3 to move downwards along with the handle 6 (because the handle fixing ring 5 is fixed with the guide ring 7, the inner wall of the guide ring 7 is matched with the balls arranged on the ball retainer, so when the handle fixing ring 5 and the guide ring 7 move downwards, the balls 9 move downwards along with the handle fixing ring 5, the balls 9 are contacted with the outer wall of the picking cylinder 1-1, the formed rolling friction force is smaller, and the resistance generated in the process of pulling the iron wire 1-3 is smaller, the picking process is easier, the guide ring 7 is limited by the positioning retainer ring 10 in the moving process of the handle fixing ring 5 and the guide ring 7), the spring 2-2 is elastically deformed, so that the four picking petals 2-1 on the picking clamp 2 are relatively rotated and opened around the fixing ring 1-4 through the hollow rotating shaft 1-5, the four picking petals 2-1 wrap fruits in the picking clamp 2, at the moment, the handle 6 is loosened by hands, the picking clamp 2 is restored to be closed under the condition of not applying force, the tops of the four picking petals 2-1 are all sharp heads, so that after the picking clamp is closed, the sharp heads at the tops of the four picking petals 2-1 cut stem rods connected with the fruits (if the picking clamp is directly cut at one time, the picking barrel 1-1 can be held by hands to integrally rotate, the stem rods connected with the fruits are twisted off), a plastic bubble protective layer can be adhered on the inner wall of the picking barrel 1-1, can avoid scratching the fruit. When the fruits fall down, the fruits touch the buffering elastic sheets 3-3 to perform certain buffering, so that the damage to the fruits is reduced, and the fruits finally fall into the containing bag 4 after falling; after the fruit falls, the buffering elastic sheet 3-3 is restored to the original state under the action of the spring hinge 3-4, the gravity impact of the falling fruit is slowed down due to repeated left-right staggering, the falling quality is guaranteed, and the operation is very convenient.

Through the mode, the novel fruit picker can solve the problems that the picking is not good due to too high fruit height and the picking is not good due to too much fruit and the top of the picker is too heavy and the picking is not handheld.
