Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary shock-absorbing handles, in particular to a shock-absorbing handle of an electric tool. Background Art

[0002] At present, most electric tools, such as impact hammers, electric picks, electric drills, angle grinders, polishers, etc. are equipped with auxiliary handles. Especially during the operation of electric hammers and electric picks with high impact performance requirements, the vibration system designed by the machine itself will produce severe vibrations, and the vibrations generated by the interaction between the tool and the working medium will be transmitted to the operator through the handle. If the handle cannot play a shock-absorbing role, the operator will feel uncomfortable such as arm numbness, fatigue, etc. after long-term work, and the work efficiency will be reduced. Therefore, a handle with shock-absorbing and shock-absorbing functions is particularly important for the operator.

[0003] The shock-absorbing handle currently on the market consists of a handle body and a connector for connecting the power tool. The connector is usually installed in the mounting hole of the handle body and fixedly connected to the handle body. The shape of the connector is basically cylindrical. In order to make the connector and the mounting hole fit better, the mounting hole on the handle body is also cylindrical. Since the top of the connector is connected to the power tool, the connector will vibrate when the power tool starts working. Since the bottom end of the connector is farthest from the top end of the connector, the vibration angle of the bottom end of the connector will be larger at this time, thereby making the vibration force generated by the bottom end of the connector larger. However, since the shape of the mounting hole is cylindrical, the contact part between the handle body and the bottom end of the connector is not thickened, thereby reducing the shock-absorbing effect of the shock-absorbing handle, and failing to offset the vibration generated when the power tool is working to the greatest extent, which is not conducive to the operator's use. Summary of the invention
