Problems solved by technology
When the user is working at heights or at an inconvenient angle, it is often difficult to activate the striking device, and the user cannot be given timely feedback, because the user cannot be reminded that the electric tool has started the striking action, and the user may inertially press it multiple times to start the electric tool. Safety performance It is not high, and the operation is not convenient enough. From the above point of view, the opening control method and related structure of traditional electric tools still need to be improved.

Abstract
The invention discloses an electric tool. The electric tool comprises a hitting shaft used for outputting hitting force, an impact block used for outputting impact force to the hitting shaft, and a case for supporting the hitting shaft and the impact block, wherein the hitting shaft can move to the first position and the second position along the first axis relative to the case; when the hitting shaft moves to the first position, the impact block is disengaged from the hitting shaft; and when the hitting shaft moves to the second position, the impact block can make contact with the hitting shaft to output the impact force. The electric tool further comprises a keeping device, the keeping device can generate keeping force for driving the hitting shaft to be kept at the first position, and when the hitting shaft is located at the second position, the keeping device generates second keeping force. The electric tool can effectively feed operation of a user back, and operation is convenientand fast.
Description
technical field [0001] The present invention relates to power tools. Background technique [0002] When electric tools such as electric hammers and electric hammers are used to drive fasteners into the base material, such as nails into the base material, in one control mode, the motor is started by pressing the wrench first, and the nail is loaded into the tool connection The striker can be activated by pressing the bottom and pressing, causing the striking device to strike the nail back and forth to drive the nail into the substrate. When the user is working at heights or at an inconvenient angle, it is often difficult to activate the striking device, and the user cannot be given timely feedback, because the user cannot be reminded that the electric tool has started the striking action, and the user may inertially press it multiple times to start the electric tool. Safety performance It is not high, and the operation is not convenient enough. From the above point of view, ...
