Problems solved by technology

However, in the actual operation process, when pruning thinner branches, the stroke of the movable blade, that is, the swing angle, seems too large for the thin branches, and the movable blade will first swing through an angle before touching and cutting the branches. There will be one section of the trip that is essentially an empty trip, so the pruning work appears to be slower and wastes time and power

Embodiment Construction

[0035] Such as figure 1 and figure 2 As shown, the electric pruning shears 10 include a housing 1, which is composed of two halves. exist figure 2 In , half of the casing is removed, which clearly shows the internal structure of the pruning shears 10 . The casing 1 is equipped with a battery 2, a motor 3, and a transmission device. The transmission device includes a reduction gear box 41 and a bevel gear transmission mechanism. The bevel gear transmission mechanism includes a driving gear 42 and a driven gear 43. The driven gear 43 is sector-shaped. A pair of blades 5 and 6 protrude from the casing 1 , wherein the fixed blade 5 is fixedly mounted on the casing 1 by bolts, and the movable blade 6 is pivotally connected to the fixed blade 5 by bolts 7 . One end of the movable blade 6 is fixedly connected with the driven gear 43, so it can swing back and forth in the direction of the arrow D under the drive of the motor 3 to realize the closing and opening of the knife edge...

Abstract

The electric pruning shears disclosed by the present invention comprise: a casing, a motor inside the casing, a transmission device connected to the motor, a pair of blade sets, and a trigger mounted on the casing for controlling the motor. The blade includes a fixed blade and a movable blade, and the movable blade reciprocates under the drive of the motor. It is characterized in that the electric pruning shears also include a travel switch installed on the casing, and the travel switch is It includes two states. When the travel switch is in the first state, the movable blade has a first stroke; when the travel switch is in the second state, the movable blade has a second stroke different from the first stroke. The pruning shears effectively overcome the defects of wasting time and electric power when the existing pruning shears cut thin branches.

Description

technical field [0001] The invention relates to an electric pruning shear, in particular to an electric pruning shear with multiple strokes. Background technique [0002] As a garden tool, electric pruning shears are widely used because of their small size and easy portability. The electric pruning shears include a pair of blades protruding from the casing, one of which is fixedly mounted on the casing, and the other blade is pivotally connected with the fixed blade and is driven by a motor to swing back and forth. When the trigger is pulled, the motor rotates forward, driving the movable blade to swing towards the fixed blade, thereby cutting the branches, and the knife edge is closed; when the trigger is released, the motor reverses, driving the movable blade to swing in the direction away from the fixed blade, and the knife edge opens . [0003] The movable blade of the existing electric pruning shears has only one stroke, that is, it can only swing within an angle rang...
