Abstract
Description
Technical Field
[0001] The present application relates to the field of agricultural picking, and particularly to a portable picking shear. Background Art
[0002] In agricultural production, the picking of fruits and other crops is a crucial link. With the continuous development of agricultural modernization, the demand for efficient and convenient picking tools is increasing day by day. In the traditional manual picking method, fruits are mainly picked directly by hand. This method is not only inefficient but also easily damages the fruits and fruit trees, consuming a great deal of human labor. In order to improve the picking efficiency and reduce the labor intensity, picking shears are usually used for picking at present.
[0003] In the prior art, the existing picking shears on the market have improved the picking efficiency and labor intensity to a certain extent. For example, a strawberry picking shear with the publication number CN109952862A drives the scissors to cut the strawberry stalk by pressing the trigger. However, this device still needs to press the trigger forcefully to provide sufficient shearing force, cannot operate continuously for a long time, and is large in size and inconvenient to carry. Another example is a sawing shear-type fruit picking tool with the publication number CN208972031U, which drives the tool assembly to cut through an electric motor. However, the shearing force of this device is insufficient, the shearing effect is unstable, it cannot shear fruit stalks or branches with a diameter greater than 4 mm, and when picking fruits, since the holding direction is parallel to the shearing direction, the wrist needs to be twisted when picking fruits, which is not suitable for long-term fruit picking operations.
