Abstract

An impact block for a power impact tool, a carrier member (30) mating the impact block (10) and the power impact tool (1) are disclosed. The impact block (10) includes an annular body (12) including an outer race (13), an inner race (14), a positioning portion (16) provided with the outer race (13) for bump fit and extending in the axial direction of the annular body (12) and one or multiple impact portion (18) provided with the inner race (14). By using the impact tool (1) composed of the above impact block (10) and the matching carrier member (30), the vibration generated by the striking process can be reduced, the striking efficiency is improved, the service life is increased, the component composition is simplified, the assembly procedure is quick and simple.

Description

technical field [0001] The present invention relates to a power tool, in particular to an impact block used in a power tool impact assembly, a retainer matched therewith, and a power tool impact assembly. Background technique [0002] In order to allow pneumatic tools or electric tools to have greater torque and impact, impact power tools with impact components installed on simple power tools have become common repair tools. [0003] There are many types of impact assemblies used in power tools, one of which is the Twin Hammer impact assembly (Twin Hammer) composed of two ring-shaped impact blocks and a rotating shaft. Due to its greater impact force and structural strength, Therefore, it is widely used in various forms of pneumatic tools. [0004] For example, US Pat. No. 6,491,111 discloses a pneumatic tool with a double-hammer impact assembly, wherein two impact blocks 40 are pivotally mounted on the holder 20 by two pins passing through the channels 38 of the holder 20 ...
