LETii Electric Screwdriver Design Description: LETii Household Electric Screwdriver effectively solves the pain point that batch head and screws are difficult to store and use, and innovatively designs the screw storage method of pressing pop-up batch head storage and bottom arc arch magnetic suction. At the same time, the operation buttons on the product can adjust the steering, adjust the torque, adjust the speed, and prompt through multiple LED lights. The operation is simpler, the holding is more labor-saving, and the storage is lighter. Positive and negative 2 kinds of rotary steering, 5 kinds of torque modes, 5 kinds of fast and slow speeds, 5 categories, 17 S2 steel precision batch heads are tough and durable. Material technology: the shell is made of ABS PA GF material, some TPU soft rubber material and UV baking varnish treatment. The internal components are made of aluminum alloy, CNC machining and anodizing. The grip is delicate and comfortable, the pressing is labor-saving, and the control is excellent. Core innovation points: 1. Unconscious button: The switch adopts the indicator button of a simple icon, which can easily control the steering torque and speed, etc., expand the versatility of the product, and achieve the most comfortable and labor-saving state to improve work efficiency. 2. Roman column texture: through man-machine test, a variety of conventional grasping methods are considered to enhance the sense of control, so that users can flexibly and efficiently complete work from different angles in a variety of holding methods. 3. Torque speed adjustment: The user can rotate the top position of the fine torque adjustment, and the LED indicator lights on the top of the product and the hand can better prompt the power and working information during work. 4. Press and pop-up magnetic attraction: Press the pop-up batch head storage and the screw storage of the bottom arc arch magnetic attraction to make up for the shortcomings of the existing products and make the operation truly efficient and simple.
