Embodiment Construction
[0082] In the present invention, an electric screwdriver is selected as the best implementation mode of the hand-held tool. There are also DC and AC electric screwdrivers. In this embodiment, a DC electric screwdriver is used as an example for specific description.
[0083] The best implementation of the hand-held tool in the present invention is not limited to electric screwdrivers, such as electric drills, electric wrenches and other rotary hand-held tools with planetary transmission are within the scope of the present invention.
[0084] refer to figure 1 As shown, it is a cross-sectional view of the hand-held tool in the preferred first embodiment of the hand-held tool of the present invention. In the figure, the hand-held tool is an electric screwdriver, which mainly includes a casing 1, a handle 11, a motor 2, a planetary gear train 3, and an output shaft 4 and trigger 5. Wherein, the handle 11 is arranged at an angle to the casing 1 on one side of the axis of the outpu...

The invention relates to a hand-held tool, comprising: a casing; a motor accommodated in the casing; a transmission mechanism connected to the motor; an output shaft connected to the transmission mechanism; a trigger arranged on the casing for controlling The motor is started; the transmission mechanism includes a planetary gear train, and the planetary gear train includes at least one planet carrier; the hand-held tool also includes a locking element that can move between a first position and a second position, and in the first position, the locking element and At least one planet carrier cooperates to limit the rotation of the at least one planet carrier; in the second position, the locking element is separated from the at least one planet carrier to release the rotation restriction on the at least one planet carrier; the trigger is operatively driven The locking element is movable from the first position to the second position. The main shaft locking structure disclosed in the present invention can occupy little or no axial dimension of the hand-held tool body, thereby making the hand-held tool body small and compact.
Description
technical field [0001] The invention relates to a hand-held tool and its operating method, in particular to a hand-held tool with a main shaft locking structure and its operating method. Background technique [0002] With the development and progress of science and technology, electric tools have become a household name and have gradually replaced manual tools, such as electric wrenches and electric screwdrivers. Labor-saving and convenience are the benefits that electric tools bring to people, but when encountering some situations where there is no power supply or insufficient power supply, such as AC tools when the power is cut off, or DC tools when the power is insufficient, people still need to find manual tools. tools to get the job done. Therefore, power tools with manual tool operation modes will undoubtedly have a wider market. [0003] The main technology to realize that the electric tool has the operation mode of the manual tool at the same time is to lock the sp...
