Abstract

一种冲击机构(104)，包括：锤击管(10)，其壁上设有至少一个通气孔(11)；离合部件(20)，其被配置成与锤击管(10)一起旋转；驱动齿轮(30)，其被配置成旋转地驱动锤击管(10)；滑套(40)，其被配置成沿锤击管(10)滑动；其中，滑套(40)、离合部件(20)和驱动齿轮(30)被配置成围绕锤击管(10)的外侧布置；且滑套(40)被进一步配置成能够在第一位置和第二位置之间移动，使得在第一位置时，滑套(40)致使锤击管(10)的至少一个通气孔(11)与周围大气连通，且在第二位置时，滑套(40)封闭锤击管(10)的至少一个通气孔(11)。还提供一种冲击式工具机(100)。该冲击机构(104)和冲击式工具机(100)结构紧凑、可避免空载冲击且易于实现更大的冲击能量。
