Starting buffer mechanism of gasoline chain saw

The utility model discloses a starting buffer mechanism of a gasoline chain saw. The starting buffer mechanism comprises a starting rope wheel (2) arranged on a gasoline chain saw starting housing (1), a starting rope (6) winding the starting rope wheel (2) and a starting handle (3). An elastic damping rubber sleeve (4) is arranged in the starting handle (3). The starting rope (6) penetrates through the elastic damping rubber sleeve (4), an upper limiting sleeve (5) and a lower limiting sleeve (7) are fixed to the starting rope (6), the upper limiting sleeve (5) is matched with the upper portion of the elastic damping rubber sleeve (4) for locating, and the lower limiting sleeve (7) is matched with the lower portion of the elastic damping rubber sleeve (4) for locating; the starting rope (6) is bent between the upper limiting sleeve (5) and the lower limiting sleeve (7), and the bent length allowance is the same as the lengthened length of the elastic damping rubber sleeve (4) when an engine is started.
