Title
(EN) POWER TOOL
Abstract
(EN)

The present invention relates to a power tool, including a housing, a motor, and a speed adjusting system decelerating the rotate rotation speed of said motor. The speed adjusting system comprises a includes an output, a main shaft connecting to the output, and a working shaft employed for adapting with corresponding working head during working. The main shaft is connected with a hammer that can move axially against the main shaft. The working shaft is connected with an anvil that rotates together with the working shaft. The hammer has first teeth, the anvil has second teeth, and the hammer drives the anvil on rotate direction through the cooperation between the first teeth of the hammer and the second teeth of anvil. The power tool also includes a clutch, which can move between the first position and the second position to optionally rigidly connect the hammer with at least one of the output and the main shaft.
