Battery System: It usually uses a 21V lithium-ion battery pack, and some products come with dual batteries for alternate use, improving work continuity. Battery capacity ranges from 1.0Ah to 5.0Ah, affecting runtime.
Blade Mechanism: Consists of a moving blade (reciprocating) and a fixed blade (stationary). The materials are mostly high-carbon steel or chrome-vanadium steel to ensure sharpness and durability.
Drive System: The core is a brushless motor (in high-end models) or an ordinary motor. The motor drives the blades in a reciprocating motion through a gearbox + eccentric shaft-link mechanism, achieving efficient cutting.
Handle and Grip: Designed ergonomically, often equipped with non-slip soft rubber sleeves, enhancing comfort and safety, especially in wet conditions or when wearing gloves.
Extendable Pole (Optional): Some high-altitude models are equipped with an adjustable 1.3–4.5 meter extendable pole, making it easier to trim branches at height and avoiding the risk of climbing.
Additional Features: High-end models may integrate a battery level display, multiple speed settings, and an intelligent safety switch, improving operational convenience and safety.
