Abstract: An adjustable flashlight including a lamp housing having a lower cover and an upper cover adapted to engage with the lower cover, a battery chamber having a lower portion, an upper portion adapted to engage with the lower portion to form a container, and a cap sealably engaged with an end of the container, and a connecting member having an outer tube, an inner tube fitted within the outer tube, and a flexible rod arranged within the inner tube, whereby the adjustable flashlight can be bent to form any desired shape, limited only by the elasticity of the material of the connecting member.

Abstract: This invention relates to a liquid dispensing controller and in particular to one which mainly includes a controlling unit and a press device whereby the liquid will not flow out of a bottle even if the bottle is overturned and may be controlled in flow rate.

Abstract: This invention relates to an improved portable air pump and in particular to one that utilizes a compressing rod, a cylinder and a base to pump air in the object that requires air. By pressing the compressing rod down, air will be forced to flow through a one way valve into an air duct and blow out of an air outlet. The spring will return the compressing rod to its original position because of its elastic force. A force block shall cause the cylinder to move forward so that a squeezer may squeeze a rubber fixture to eliminate an air gap so that air will not flow toward other directions but air nozzle as desired.
