Abstract: An interproximal squirt brush includes a squeezable bottle having a solution cavity for containing a washing solution and a nozzle head having an opening, and a brush head including a brush arm and a brush member. The brush arm has a brush portion and a resilient portion slidably inserted into the opening of the squeezable bottle for providing an urging force against an inner wall of the nozzle head, wherein a dispensing channel is formed between the resilient portion of the brush arm and the inner wall of the nozzle head for allowing the washing solution to pass therethrough. The brush member is provided at the brush portion of the brush arm. Therefore, when a squeezing force is applied on the squeezable bottle, the washing solution is released to the brush member through the dispensing channel of the nozzle head.

Abstract: A charger with a replaceable signal for a car includes a casing and a circuit board. The casing is provided with a current taking plug at a lateral side thereof. The circuit board is disposed in the casing and electrically connected to the current taking plug for rectifying and transformed an input power. It is characterized in that the casing at a proper position thereof is provided with a signal socket to electrically connect with the circuit board and a stopper being located therein; a signal line at an end thereof has a signal plug being detachably inserted into the signal socket and the stopper has an engaging piece for engaging with the signal plug and allowing the signal line fixedly joined to the casing laterally and the signal line at a another end thereof has a connector. Once the connector of the signal line is connected to an output/input port of a personal electric product and the current taking plug is inserted to a lighter device in a car, a recharging circuit can be performed.

Abstract: A cylindrical terminal rivet integrally made of metal comprises a base plate, a cylinder, and an elongated plate. The base plate provides a central hole and the cylinder with a closed upper end extends upright from the base plate and communicates with the central hole. The elongated plate extends outward from a lateral side of the base plate and provide at least a wing piece at two opposite edges thereof respectively. The cylinder is arranged to pass through a work piece and pressed to form a pancake like solid body so as to urge the work piece tightly and to block the central hole. Furthermore, a battery snap can be composed of two cylindrical terminal rivets, an insulation piece, a male engaging post, a female engaging post and a covering band.

The elongated plate extends outwardly from a lateral side of the base plate and has at least a wing piece at two opposite edges. The cylinder is arranged to pass through a work piece and pressed to form a flattened solid body so as to clamp the work piece tightly and to block the central hole. Furthermore, a battery snap can be composed of two cylindrical terminal rivets, an insulation piece, a male engaging post, a female engaging post and a covering band.
