The invention relates to a hand-held electric tool. The hand-held electric tool comprises an enclosure, a motor arranged in the enclosure and used for outputting a rotating power, an output shaft provided with an axially-arranged holding hole for holding a work head, a transmission mechanism arranged between the motor and the output shaft and capable of transmitting the rotating power output by the motor to the output shaft, a work head support mechanism arranged in the enclosure and provided with a plurality of parallel holding spaces used for supporting the work head, and a connection shaft arranged in the enclosure and capable of locating the work head at a work position in the holding hole or locating the work head at a holding position of the work head support mechanism, wherein the work head comprises at least one driver bit and at least one drilling bit. The hand-held electric tool further comprises an operating mechanism used for selectively driving the connection shaft so as to locate the drilling bit at a holding position and locate the driver bit at a work position or locate the driver bit at the holding position and locate the drilling bit at the work position. The invention further relates to an operating method of the hand-held electric tool.
Description
technical field [0001] The invention relates to a hand-held electric tool and an operation method for the hand-held electric tool, in particular to a gun drill type hand-held electric tool capable of realizing the storage and quick replacement of the working head and the gun drill type hand-held power tool. How to operate the power tool. Background technique [0002] Among the existing gun drill type hand-held electric tools, electric drills, electric drills and impact drills are usually included. [0003] The electric drill is used to drill holes on the workpiece. During the operation, the drill shaft continuously rotates. An electric drill is a common power tool used to tighten screws into workpieces. Usually, the user needs to drill the hole first and then screw the screw when performing the operation. In this way, it will be very troublesome for the user to prepare two different types of power tools and to constantly replace them for operation. [0004] Of course, th...
