Scroll saw

The utility model discloses a scroll saw which comprises a machine shell, a driving motor, a reciprocating rod and a transmission mechanism. An output shaft is arranged on the driving motor, and the transmission mechanism comprises a first gear and a second gear, wherein the first gear and the output shaft are coaxially arranged, and the second gear is meshed with the first gear. A fixed shaft is fixedly arranged on the machine shell, a bearing is arranged on the fixed shaft, and the second gear is arranged on the bearing. The fixed shaft is provided with a stepped part which extends in the axial direction and used for positioning the bearing and the second gear, and a fixing part is arranged on the second gear. A sliding assembly is arranged on the reciprocating rod, and one end of the fixing part is matched with the sliding assembly and can reciprocate on the sliding assembly. According to the scroll saw, the stepped part extends in the axial direction of the fixed shaft and can block the bearing and the second gear in the operation process of the scroll saw so that axial movement can be prevented from being generated; the speed of abrasion between the fixed shaft and the second gear is decreased, so that the service life of the scroll saw is prolonged.
