Title:
RECIPROCATING SAW
Document Type and Number:
WIPO Patent Application WO/2021/093514
Kind Code:
A1
Abstract:
Disclosed is a reciprocating saw, comprising a housing (100); an electric motor (200); a transmission mechanism (300), the transmission mechanism being driven by the electric motor to drive a saw blade to move in a reciprocating manner; an object for detection (400) arranged on the transmission mechanism and capable of moving to a first position along with the transmission mechanism, wherein when the object for detection moves to the first position, the reciprocating saw is in a working stroke state or an idle stroke state; a first detector (500) for detecting the object for detection and arranged opposite the first position; and a control circuit board (600), which is electrically connected to the first detector and the electric motor and adjusts the rotation speed of the electric motor when the first detector detects the object for detection. The reciprocating saw can effectively control the rotation speed of the electric motor according to stroke requirements, thereby preventing a cutting speed from being reduced while reducing vibration of the saw blade.
