Double-stretching stroke-type shears for branches and leaves in garden

Abstract

The invention relates to double-stretching stroke-type shears for branches and leaves in a garden. The shears comprise a handheld housing, a low-load elastic tool, a heavy-load elastic tool and a shearing device; the handheld housing includes a rectangular rod and a rectangular inner cavity; the low-load elastic tool includes a first mother cylinder, a first child cylinder, an upper inner threadedpipe, an upper outer threaded pipe and first compressed springs; the heavy-load elastic tool includes a second mother cylinder, a second child cylinder, a lower inner threaded pipe, a lower outer threaded pipe and second compressed springs; the shearing device comprises a fixing transverse arm, an adjusting round bar and a movable transverse arm. According to the double-stretching stroke-type shears for the branches and leaves in the garden, the branches are cut through a cutting disc in advance, and then the adjusting round bar is pulled down to drive the movable transverse arm to move downuntil the branches are sheared off. The downward stroke of the adjusting round bar is divided into two steps in order to better adapt to realization of the function of shearing off the branches.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-stretching stroke-type leaf scissors 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. [0004] Therefore...
