Description

Technical Field

[0001] The utility model relates to the technical field of girdling pliers, in particular to a pair of girdling pliers for fruit trees. Background Art

[0002] Ring barking is a method of peeling the bark in a ring shape. After peeling off a circle of bark from the trunk, the nutrients on the trunk will not flow back to the roots in autumn and winter. In spring, the grass and trees sprout, and the nutrients from the roots are transported upward. When the wound peeled last year is healed, the flowers on the tree have bloomed and the young fruits have formed. It is a method to increase fruit yield. When ring barking fruit trees, the bark needs to be ringed with ring barking pliers.

[0003] The utility model patent for fruit tree ring-barking pliers with patent number CN220755649U includes a handle, an adjustment component is provided on the handle, two mounting arms are provided on the adjustment component, and two pulleys are provided on the opposite surfaces of the two mounting arms. A mounting frame component is provided at the end of the handle close to the pulley, and a blade is provided at the movable end of the mounting frame component so that the blade is close to the surface of the fruit tree. Regardless of the diameter of the fruit tree, the user only needs to push the handle to complete the ring-barking of the fruit tree.

[0004] Although the above scheme can adapt to the sizes of different fruit trees to a certain extent, it has great limitations in actual use. After each ring-barking of a fruit tree, the two mounting arms need to be opened through the adjustment component, and then put on the branches of the next fruit tree and the distance between the two mounting arms is adjusted through the adjustment component. In addition, the position of the blade needs to be continuously adjusted through the mounting frame component according to the size of the fruit tree. The operation is complicated and greatly reduces the work efficiency. In addition, the depth of the ring-barking cannot be controlled during the ring-barking. If the ring-barking is too deep, it is very easy to damage the wood of the fruit tree. Utility Model Content
