Problems solved by technology

[0003] During use, the fixed blade is mainly responsible for supporting, and the movable blade is responsible for cutting, and the cutting edge angle of the movable blade is small and the thickness is thin, so the movable blade is relatively easy to wear, and the blunt wear of the movable blade will affect the cutting efficiency and cutting efficiency. effect, so often need to be replaced
Most of the electric pruning shears currently on the market need to disassemble the casing when replacing the movable blade, which is very troublesome to replace. The bolts for the movable blade and the fixed blade, the steps of replacing the blade are still relatively cumbersome

Embodiment Construction

[0016] figure 1 It is a perspective view of electric pruning shears according to a preferred embodiment of the present invention. Such as figure 1 As shown, the electric pruning shears 10 includes a casing 1, which contains a motor 14, a transmission mechanism 3, a built-in battery (not shown in the figure), and a switch trigger 11 and a safety switch are installed below the casing 1. The switch 12 is used to control the opening and closing of the motor 14 . The rear of the cabinet 1 forms a grip portion 13 . Movable blade 21 and fixed blade 22 extend from the front end of casing 1, and fixed blade 22 is fixedly installed in casing 1 by screw or other means, and movable blade 21 is rotatably connected to fixed blade 22 by shaft (4), In this embodiment, the shaft (4) is embodied as a bolt.

[0017] Such as figure 2 Shown, have groove 23 on the movable blade 22, and this groove 23 comprises the first groove 24 and the second groove 25 that pass through each other, and the ...

Abstract

The invention provides electric pruning shears. The pruning shears comprise a case, a motor and a transmission mechanism, wherein the motor is contained in the case; a movable blade and a fixed blade extend out from the front end of the case; the fixed blade is fixedly installed on the case; the movable blade is driven by the motor and is rotatablely connected on the fixed blade by a shaft; a slot is arranged on the movable blade and comprises a first slot and a second slot which are communicated with each other; the dimension of the first slot is greater than that of the second slot; the shaft comprises a first matching part and a second matching part; the shaft can move between a first position and a second position; in the first position, the first matching part is matched with the first slot and the movable blade is locked; and in the second position, the second matching part is matched with the first slot and the movable blade is loosened. Therefore, the movable blade can be replaced very simply and conveniently.

Description

technical field [0001] The invention relates to an electric pruning scissors, in particular to a quick blade replacement structure of the electric pruning scissors. Background technique [0002] As a garden tool, electric pruning shears are small in appearance and easy to carry, and are a commonly used tool in gardening pruning. This type of electric pruning shears includes a movable blade and a fixed blade, the fixed blade is fixedly installed on the casing, the movable blade is rotatably connected to the fixed blade, and the movable blade is driven by the motor through the transmission mechanism to reciprocate and swing, thereby implementing shear action. [0003] During use, the fixed blade is mainly responsible for supporting, and the movable blade is responsible for cutting, and the cutting edge angle of the movable blade is small and the thickness is thin, so the movable blade is relatively easy to wear, and the blunt wear of the movable blade will affect the cutting ...
