Description

technical field [0001] The present invention relates to a clutch device, more specifically a clutch device used on an electric hammer. Background technique [0002] The clutch device installed on the electric hammer can prevent the large torque reaction force from being transmitted to the user due to the sticking of the drill bit during use, which is a kind of safety protection for the user. Moreover, this mechanism can also be used in the functional shifting of the mechanism to achieve the effect of effectively protecting the gears during shifting. The safety and reliability of the clutch device used on the electric hammer in the prior art needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clutch device installed on an electric hammer to improve safety and reliability. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical so...
