Abstract

The invention relates to an adjusting method suitable for a double-stretching stroke type branch and leaf shear of a garden. The double-stretching stroke type branch and leaf shear of the garden is used for the garden and comprises a handhold shell, a low-load elastic tool, a heavy-load elastic tool and a shearing device. The pre-adjusting method includes the following steps that 1, the extreme retraction stroke of the low-load elastic tool is adjusted; 2, the extreme retraction stroke of the heavy-load elastic tool is adjusted. According to the adjusting method, the descending process of an adjusting round rod is divided into two steps to better adapt to realizing tree branch shearing. Through resistance mutation of pulling of the adjusting round rod, it is known in advance that a cuttingwheel disc will cut tree branches, and therefore it is avoided that the cutting wheel disc rapidly cuts into the tree branches and gets blocked because the adjusting round rod and a movable transverse arm are rapidly pulled downwards; with large resistance, the speed of downward pulling can be decreased to a certain degree for a user, and is just suitable for slow descending rhythm needed when the cutting wheel disc cuts the tree branches at this moment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustment method for a double-stretch type leaf shears suitable for gardens. Background technique [0002] During landscaping construction, the branches and leaves of trees need to be pruned. Traditional branch and leaf shears simply cut through the shear stress of two hinged scissor arms, but this method is time-consuming, laborious and inefficient. [0003] The existing technical scheme has carried out automatic improvement to the traditional scissors structure, and a cutting wheel or a chain saw are set on any scissors arm to assist in cutting. But in the cutting process, because the cutting speed of the two scissor arms is not easy to control, the cutting wheel or the chain saw often do not cut the branches and leaves in advance, but the scissor arms cut quickly, causing the cutting wheel or the chain saw to jam. live and cannot perform effective cutting.
