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] like figure 1 and figure 2 As shown, the electric pruning shears 10 comprise a casing 1, which is composed of two half casings. exist figure 2 , in which half of the casing is removed, which clearly shows the internal structure of the pruning shears 10 . The casing 1 houses a battery 2, a motor 3, and a transmission. The transmission device includes a reduction gear box 41 and a bevel gear transmission mechanism, and the bevel gear transmission mechanism includes a driving gear 42 and a driven gear 43, and the driven gear 43 is fan-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 arrow D under the drive of the motor 3 to realize the closing and opening of the blade 60 .

Abstract

The invention discloses a pair of electric pruning shears which comprises an enclosure, a motor positioned in the enclosure, a transmission gear connected with the motor, a pair of blade groups, and a trigger arranged on the enclosure and used for controlling the motor, wherein the pair of blades comprise a fixed blade and a movable blade, and the movable blade is driven by the motor to conduct reciprocating swing. The pair of electric pruning shears is characterized by also comprising a stroke switch arranged on the enclosure, wherein the stroke switch at least comprises two states, when the stroke switch is in the first state, the movable blade has a first stroke, and when the stroke switch is in the second state, the movable blade has a second stroke which is different from the first stroke. The pair of electric pruning shears effectively overcomes the defects of waste of time and power when a pair of conventional pruning shears is used for shearing twigs.

Description

technical field [0001] The invention relates to an electric pruning shear, in particular to an electric pruning shear with various 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 comprise a pair of blades protruding from the casing, wherein one blade 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 closing the blade; when the trigger is released, the motor reverses, driving the movable blade to swing away from the fixed blade, and the blade opens . [0003] The movable blade of the existing electric pruning shears has only one stroke, that is, it can only swing within an angle range, and it is either clos...
