Abstract: The disclosure discloses a clip-on desk lamp, including a holder including a first clamping part which has a first clamping fixed end and a second clamping part which has a second clamping fixed end, wherein the first clamping part and the second clamping part are hinged by torsional spring so as to make the first clamping fixed end and the second clamping fixed end generate opposite clamping forces; a first adjusting plate arranged between the first clamping fixed end and the second clamping fixed end, and mounted to the first clamping fixed end rotatably; a lamp body mounted on a side of the second clamping part departing from the first clamping part.

Abstract: A smart wearable device and a charger thereof includes the smart wearable device and a charging base configured to charge the smart wearable device. The charging base comprises an elastic case. An open slot for inserting the smart wearable device is formed in the elastic case. A power supply portion is disposed on the charging base. The power supply portion provides the smart wearable device with electrical energy for charging. The smart wearable device is fixed to the charging base by way of a close fit between slot walls on two sides of the open slot and an outer surface of the smart wearable device.

Abstract: A universal serial bus (USB) cover connecting structure of an electronic product is provided, including a USB cover, covering a USB port of the electronic product, and disposed on a case of the electronic product. A first extending part and a second extending part are disposed on opposite ends of the USB cover, and a first gap and a second gap are formed between the first extending part, the second extending part, and sidewalls of the USB cover, so that while one of first and second extending parts is pressed, the other one of the first and second extending parts will be lifted, thereby forming a digging position for a finger to easily pull the USB cover out. Costs of molds and production are reduced due to removal of a groove.
