Title:
IMPACT TOOL
Document Type and Number:
WIPO Patent Application WO/2019/158115
Kind Code:
A1
Abstract:
An impact tool having at least two operation modes: an impact mode and a non-impact mode. The impact tool comprises a housing (10), a motor (30), a cutting tool main shaft (50), an impact mechanism (40), and a transmission mechanism (20). The impact mechanism comprises a hammer (410) and a guide member (420) capable of rotating relative to each other. When rotating relative to the guide member, the hammer axially impacts the cutting tool main shaft. A mode adjustment mechanism is operable to switch between a first state and a second state. In the first state, the hammer rotates relative to the guide member, and the impact tool is in the impact mode. In the second state, the guide member is driven by the motor to rotate, and the impact tool is in the non-impact mode. The mode adjustment mechanism changes a relative motion state of the hammer and the guide member, thereby providing a mode switching solution having a simple structure.
