Impact tool

Abstract

The application discloses an impact tool, comprising: a casing; a cylinder installed in the casing, a peripheral wall of the cylinder being provided with a gas hole; a cylinder sleeve slidingly fitted on the outer periphery of the cylinder and being driven to move to close or open the gas hole; a fixing seat fixed in the casing and abutting against the end of the cylinder; a driving pin slidingly fitted with the fixing seat; a buffer assembly slidingly fitted in the casing, two ends of the driving pin abutting against the buffer assembly and the cylinder sleeve respectively; an impact assembly comprising an impact sub and an impact hammer, the impact sub being located at the end of the fixing seat away from the cylinder, and the impact hammer being arranged in the cylinder to impact the impact sub. When the impact tool is in operation, the driving pin can drive the cylinder sleeve to move, so as to adjust the opening and closing state of the gas hole, and finally the impact hammer impacts the impact sub to complete the impact work. The fixing seat can abut against and support the cylinder seat, and the buffer assembly can abut against and buffer the driving pin, so that the reliability of the gas exchange structure and the normal use of the electric tool can be ensured.
