Abstract
The present invention relates to a portable power tool () arranged for driving a rotatable cutting tool (). The power tool () comprises a motor () and a transmission part () that is arranged to transfer power from the motor () to a tool holder (), and comprises a first arm part (') and a second arm part (′). The first arm part (′) comprises a first belt pulley () and the second arm part comprises a second belt pulley (), the arm parts () being slidably connected to each other. The belt pulleys () are spaced apart by a certain distance (d-i, d). The transmission part () further comprises a tensioning device () with a rod (), a pre-tensioned resilient device (), a linkage arrangement () and a rotatable part (). The rotatable part () is rotatable between a first, released, state where the belt pulleys () are spaced apart by a first distance (d-i), and a second, tightened, state where the belt pulleys () are spaced apart by a second distance (d) that exceeds the first distance (d-i), the resilient device () being more compressed in the second state than in the first state.
