The first annular groove (321)is 4 A - provided therein with a first snap spring (C) abutting against 3 a fifth bearing (8), and the second annular groove (322) is provided therein with a second snap spring (D). At the same 22 time, the small output shaft (32) is provided thereon with an 5 elastic piece (10) which is hogged towards the side of the second snap spring (D) and the two ends thereof respect 33 35 ively abut against the second gear (34) and the second snap 8 -- - spring (D). The cutting machine has the following advant - ages: it can prevent the small output shaft from stretching c 351 out and drawing back, absorb manufacturing tolerances ac cumulated by each component, enable the small output shaft E- to have a pre-tightening force along the axial direction, so as to ensure the conformability of the axial positions of the two 7 shafts, enable the inner saw blade to have a limited space to slide between left and right, and ensure the two saw blades always have an appropriate relative clearance between each 3 21 1 other, so as to perform the cutting operation smoothly and R2 /Fig.2 reliably.
