Embodiment approach

[0040] refer to Figure 8 As shown, it is the second embodiment of the electric tool of the present invention as the emergency lighting lamp. The control circuit E' is similar to the previous embodiment, the difference is that the control switch K1 of the emergency lamp L in the control circuit E' A control switch K2 is connected in parallel at the place, and other identical components are indicated by the same label, which will not be repeated here; in the control circuit E', due to the setting of the control switch K2, the electric screwdriver is inserted into the charging device 11 before, It is not necessary to turn the rotary sleeve 8 to make the lighting control mechanism 40 in the closed state, but to close the emergency light L by controlling the switch K1, so as to achieve the same emergency lighting effect when encountering a power failure during the charging process, and at the same time make the The operation becomes simpler and more convenient.

Abstract

The invention relates to an automatic screw driver with lighting function that comprises the body of the tool, charging device connected with the tool body which has the motor, battery, working element rotated by the said motor, lighting device connected to the said battery, control circuit in coordination with the lighting device that can be used independently. When the tool body is charging, the control circuit control lighting element will not illuminate, when the charging device is cut off, it will beam for emergency lightening.

Description

technical field [0001] The invention relates to an electric tool, in particular to an electric screwdriver with an illuminating device. Background technique [0002] Usually, existing electric tools such as electric screwdrivers, household electric vacuum cleaners, etc. only have a small light source as a very weak auxiliary lighting during work, or an indicator light is set on the tool to indicate the working condition of the electric tool. Such auxiliary lighting lamps or indicator lights only have auxiliary functions for electric tools, and do not have independent functions. [0003] As disclosed in U.S. Republished Patent No. 38729, an electric screwdriver is equipped with a combined tool with an auxiliary lighting device, including a handle and a cylinder connected to the handle, wherein a battery is arranged in the handle, and the end of the cylinder is rotatably connected An output shaft, a switch electrically connected between the battery and the output shaft for co...
