Problems solved by technology

[0004] 1) In the existing handle-type structure, because the internal space of the handle is relatively small, and the handle is not easy to be too long, it is impossible to install the power indicator light and LED lighting at the same time
[0005] 2) To install LED lighting, parts such as step-down boards are required, and the space required is too large
[0006] 3) If the power indicator and L

Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, it is a schematic diagram of a power tool with lighting and power indicating devices. The power tool preferably takes an impact wrench 100 as an example, including a main body 20, and the main body 20 includes a hammer-shaped box 26 and a housing 27, wherein the hammer-shaped The case 26 forms the front end portion of the main body, and the housing 27 is connected to the hammer case 26 and forms the rear of the main body 20, and a motor serving as a driving source is accommodated in the housing 27, and includes, for example, a reduction mechanism for transmitting the torque of the motor. (not shown). A terminal output unit (not shown) including an impact mechanism is accommodated in the hammer case 26, which is drivably connected to the motor, and a tool holder 28 is supported at the fr...

Abstract

The invention provides a power tool, which comprises a motor, a body, a handle and an illuminating and power indicating device. The motor serves as a driving power source, the body for containing the motor is provided with a terminal output unit, the terminal output unit drives a terminal tool clamped by a tool holder at the front end of the body, the handle and the body are approximately in T-shaped arrangement, the illuminating and power indicating device is provided with an illuminating light outlet and a power indicating light outlet which penetrate through a shell of the handle, the illuminating light outlet is positioned on the front side of the handle, and the power indicating light outlet is positioned on another side of the handle except for the front side of the handle. The power tool is simultaneously provided with an LED illuminating lamp and a power indicating lamp, and can function in both illumination and power indication. Moreover, the LED illuminating lamp and the power indicating lamp are arranged in the same local space positioned at the tail end of the handle, mounting space is saved, and the power tool has the advantages of easiness in carrying and operation and the like without lengthening the handle.

Description

technical field [0001] The invention relates to a power tool, in particular to a power tool with lighting and power indicating devices. Background technique [0002] In the prior art, electric tools are widely used in various fields, especially impact wrenches, impact electric drills, etc., which are widely used. During operation, the tools are often required to be equipped with a certain lighting function, which is convenient for illuminating work in places where the light is not clear. At the same time, it is better to be equipped with a power indicator light to remind the operator of the power supply status of the tool, while the ordinary AC impact wrench only has the function of a power indicator light, and there is no existing power indicator light, and it also has an LED AC impact wrench with illuminated features. [0003] The patent US06206538 discloses a structure with a lighting lamp at the bottom of the handle of an electric tool, but there are still some technica...
