Problems solved by technology

In the past, the structure of high-branch shears, such as the case of Taiwan Patent Certificate No. M393982, mostly used mechanical structures such as springs, swing arms, and drawstrings to drive the blades, so it was laborious and inconvenient to use, and it could not produce strong shearing. In addition, because the branches are thin and thick, and the size of the opening that can be opened by general high-branch shears is fixed, it is impossible to cut too thick branches during use, so the applicability is poor. needs to be improved

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] refer to figure 1 , figure 2 and image 3 , a preferred embodiment of the high-branch shears of the present invention includes a housing unit 1 , a scissors unit 2 , an electronically controlled driving unit 3 , and a mode switching unit 4 .

[0023] The shell base unit 1 includes several shell pieces 11 that are correspondingly matched and interlocked. The shell pieces 11 together define a receiving space 12 and an opening 13 connected to one side from the receiving space 12 . The housing unit 1 further includes a mounting seat 14 installed in the receiving space 12 and adjacent to the opening 13 .

[0024] The scissors unit 2 is installed on the mounting base 14 of the housing unit 1, and protrudes outward from the opening 13, and includes a fixed blade 21 fixed on the mounting base 14, and a blade that can rotate relative to the fixed bl...

Abstract

The invention discloses a tree pruner capable of controlling a pruning wound. The tree pruner comprises a shell base unit, a shear unit and an electric control driving unit, wherein the shear unit comprises a fixed blade and a rotary blade; the electric control driving unit is arranged in the shell base unit, and comprises a swinging arm for driving the rotary blade, and a power source for driving the swinging arm; and the swinging arm is driven to drive the rotary blade to move between a closing position close to the fixed blade and an opening position deviated from the fixed blade relative to the fixed blade. Due to the adoption of the design, the effects of electrically controlling the shear unit to open and close and being used conveniently in a more labor-saving way can be achieved.

Description

technical field [0001] The invention relates to a high-branch shears, in particular to a high-branch shears with a controllable notch for cutting branches. Background technique [0002] In order to prevent the branches and leaves of trees from spreading and extending at will, it is necessary to trim them in time to avoid falling branches and hurting people, or blocking the line of sight and hindering the cityscape. It is more convenient for tall branch shears to cut by cutting. In the past, the structure of high-branch shears, such as the case of Taiwan Patent Certificate No. M393982, mostly used mechanical structures such as springs, swing arms, and drawstrings to drive the blades, so it was laborious and inconvenient to use, and it could not produce strong shearing. In addition, because the branches are thin and thick, and the size of the opening that can be opened by general high-branch shears is fixed, it is impossible to cut too thick branches during use, so the applic...
