The fruit presser prevents the fruits from coming up and the elastic part prevents penducles from excessive pulling by the chucks.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bag-removal stalk-cutting device for packaged fruits with stalks, which cuts off the stalks of packaged fruits with stalks and removes the bag. .

When cultivating fruits such as pears and apples, cover the fruit with a paper bag during cultivation and close the opening of the bag to prevent the fruit from being attacked by pests and diseases, or to protect it from wind, rain, and sunburn. It is fixed and supported on the peduncle by tightening with a fastener such as wire.

When harvesting fruit, the fruit is separated from the fruit tree in its bag as a packaged fruit with stalks, and then the packaged fruit with stalks is cut off again using a bag removal stalk cutting device 1, and the bag is removed. It is common to remove it.
