Description

Technical Field

[0001] The utility model belongs to the technical field of electric wrenches, and particularly relates to a wrench with an illumination function. Background Art

[0002] An electric wrench is a commonly used mechanical maintenance tool for disassembling and assembling screws. For some products, the mechanical structure is relatively complex, and the screws are installed in relatively deep grooves or corners where natural light is not easily transmitted, resulting in darker light in the grooves or corners, making it difficult to clearly see the specific position of the screws. Generally, existing electric wrenches often do not have an illumination function. Especially when working and detecting in the wild at night, in case of mechanical failures, timely repairs are often required. Due to the dark environment, maintenance personnel usually hold a flashlight in one hand and an electric wrench in the other hand for operation, which is very inconvenient and unsafe during the operation process. Therefore, it is necessary to design a wrench with an illumination function to overcome the above difficulties. Summary of the Invention

[0003] In view of the problems existing in the prior art, the utility model designs a wrench with an illumination function. The utility model is provided with a light-emitting illumination component and an electronic control module in the frame body. When the motor works, the electronic control module controls the light-emitting illumination component to emit light, which is convenient to use and safe and reliable.

[0005] Preferably, the electronic control module includes a main control circuit board, a key panel and a power socket; the key panel electrically connected with the main control circuit board is arranged above the main control circuit board, and the key panel is snap-connected with the frame body; the power socket electrically connected with the main control circuit board is arranged below the main control circuit board, and the power socket is snap-connected with the frame body; the power socket and the battery pack are mutually snap-connected, and when the battery pack is in contact with the power socket, the main control circuit board is in a powered-on state.

[0006] The main control circuit board is powered by the battery pack, and the main control circuit board can drive the motor to rotate when receiving an electrical signal. Different electrical signals can be sent to the main control circuit board through the key panel, so that the light-emitting illumination component emits light with different brightnesses.

[0007] Preferably, the button panel is provided with adjustment buttons which are symmetrically distributed on the button panel. By pressing the adjustment buttons, different electrical signals are received by the main control circuit board, and the voltage between the main control circuit board and the lighting component changes, so that the brightness of the lighting component changes, thus facilitating the adjustment of the brightness of the lighting component.

[0008] Preferably, the main control circuit board is electrically connected to the lighting component, the main control circuit board is electrically connected to the button switch, and the main control circuit board is also electrically connected to the motor; when the button switch sends an electrical signal to the main control circuit board, the motor rotates and the lighting component lights up synchronously; the lighting component is an LED lamp. When the button switch is pressed, it sends an electrical signal to the main control circuit board, so that the main control circuit board drives the motor to rotate. At the same time, the circuit between the main control circuit board and the lighting component is turned on and the lighting component emits light. Here, a delay circuit is provided between the lighting component and the main control circuit board. When the button switch is released, the motor stops rotating, and at this time, the circuit between the main control circuit board and the lighting component does not immediately disconnect; 20 seconds after the motor stops rotating, the lighting component automatically turns off.

[0011] Preferably, a strip-shaped protrusion is provided at the output end of the frame body. The strip-shaped protrusion is arranged below the columnar protrusion; the edge of the lighting component abuts against the strip-shaped protrusion; a first groove is provided at the bottom of the protective cover, and the strip-shaped protrusion is stuck in the first groove. The contours of the first groove and the strip-shaped protrusion are adapted to each other.

[0012] By providing the strip-shaped protrusion, it is convenient to limit the edge of the lighting component; at the same time, the strip-shaped protrusion is arranged in the first groove, so that the whole protective cover covers the lighting component and the protective cover cannot rotate relative to the frame body; secondly, the edge of the first groove fits with the edge of the strip-shaped protrusion, and the edge protrusion of the lighting component is also stuck in the first groove, so that the lighting component cannot rotate relative to the frame body either, and the lighting component is installed more firmly.

[0013] Preferably, both the protective cover and the illuminating member are disc-shaped and coaxially arranged, and the protective cover is transparent.

[0014] Compared with the prior art, the utility model has the following beneficial effects: 1. A detachable illuminating member is arranged at the output end of the main body of the frame and fixed by the protective cover, with good lighting effect and safe and reliable use. 2. The illuminating member is electrically connected to the electronic control module, and the illuminating member and the electronic control module are connected through ports, which is convenient to replace and does not affect the output of the wrench. 3. The brightness of the illuminating member can be conveniently adjusted through the adjustment button on the electronic control module, with good versatility. 4. The electronic control module can control the illuminating member to automatically cut off the power, with a longer service life. Description of the Drawings
