Embodiment Construction
[0062] In the preferred embodiment of the electric tool of the present invention, the electric tool is a hand-held multifunctional electric drill capable of realizing the functions of a drill and a screwdriver. There are also DC and AC in the electric drill. This embodiment preferably takes the DC multifunctional electric drill as an example for specific illustrate.
[0063] refer to figure 1 and figure 2 As shown, the DC multifunctional electric drill includes a casing 1, a motor 2, a battery 6, a transmission mechanism 3a, a connecting piece 51, a working head support mechanism and an output shaft 4a. The casing 1 is composed of two symmetrical half shells assembled by screws (not shown). It has a horizontal part and a handle 11 part which is set at an obtuse angle with the horizontal part. The preferred angle of the present invention is 100 degrees to 130 degrees. Between degrees, it will be more comfortable when holding the handle 11 for operation. A button switch 7 is...

The invention relates to an electric tool which comprises a machine shell, a motor, an output shaft, a transmission mechanism, a working head supporting mechanism, a connecting member, and a switching device. The motor is arranged in the machine shell and outputs rotating power, the output shaft is provided with an axially-arranged containing hole for containing a working head, the transmission mechanism is arranged between the motor and the output shaft and transmits the rotating power output by the motor to the output shaft, the working head supporting mechanism is provided with a plurality of containing spaces arranged parallelly and used for supporting the working head, and can be adjusted to positions, axially corresponding to the containing hole, in different containing spaces, the connecting member is arranged in the machine shell and can enable the working head to be positioned at a working position in the containing hole and to be positioned a containing position of the working head supporting mechanism, the working head supporting mechanism can be operated to move from a position, axially corresponding to the containing hole, in one containing space to a position, axially corresponding to the containing hole, in another containing space, and switching device changes rotating speed output by the output shaft.
Description
technical field [0001] The present invention relates to an electric tool and an operating method for the 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 electric tool How to do it. 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, the operator can prepare two...
