Abstract: A working tool including a tool body with a distal end at which a first engagement structure is disposed and an interchangeable working member including a mounting base and a working portion connected to a distal end of the mounting base. The mounting base includes a second engagement structure disposed at a proximal end of the mounting base and configured to engage with the first engagement structure. The working member is configured to be electrically connected with the tool body upon attachment to the tool body. The working tool is configured to allow the working member to be detached from the tool body and allow another working member with the second engagement structure to be attached to the tool body.

Abstract: A striking tool, comprising a striking head for performing a striking task and a handle connected to the striking head. The handle extends in a direction substantially transverse to a striking direction of the striking head, and comprises a rigid segment having a first rigidity and a flexible segment having a second rigidity sequentially in a direction away from the striking head, the second rigidity being less than the first rigidity. The handle is provided with a gripping part at a position corresponding to an end of the rigid segment that is connected to the flexible segment. The gripping part for a user to grip on the handle thereof is arranged at the end of the rigid segment that is connected to the flexible segment, so as to correspond to one the nodes of vibration formed on the handle during striking.
