Description

Technical Field

[0001] The utility model relates to the technical field of electric scissors, in particular to a pair of anti-slip gardening electric scissors. Background Art

[0002] Gardening shears are a kind of gardening tool used to prune the branches of flowers and trees and prune diseased and insect-infested branches to keep the trees beautiful and make the flowers and trees grow according to the grower's wishes. The gardening shears widely used on the market are similar to ordinary scissors. They are made of two scissors blades connected to the handle with a cross-axis connection. Since pruning shears cut through tough wood materials, with the development of greening, pruning shears will become an indispensable greening tool.

[0003] Electric gardening shears will generate high-frequency vibrations when in use, and workers often wear canvas gloves when in direct contact with the shears. The canvas gloves will reduce the friction between the electric shears and the shears. The high-frequency vibrations can easily cause the electric shears to slip, posing a safety hazard to the workers. The existing device can also increase the friction between the user and the electric shears body through an anti-slip rubber sleeve. Although the friction between the worker's hand and the shears handle is increased, the electric gardening shears will generate high-frequency vibrations when in use, which can easily cause fatigue in the hands of the people. If the hands and the shears handle fall off, it will cause harm to the workers. Therefore, a pair of anti-slip gardening electric shears is proposed to address the above problems.
