Abstract: A tool box includes two first bodies and each first body has two first connection portions on the first end thereof. Two connectors are respectively connected to the first connection portions and each connectors has a second pivotal portion and a third pivotal portion. The second pivotal portion is a tubular portion with a C-shaped cross section which includes an elongate opening defined axially therethrough. The width of the elongate opening is smaller than the inner diameter of the second pivotal portion. The third pivotal portion is a rod which shares a common axis with the second pivotal portion. The diameter of the third pivotal portion is equal to or smaller than the inner diameter of the second pivotal portion. The third pivotal portions on one of the two first bodies are pivotably connected to the second pivotal portions on the other one of the two first bodies to pivotably connect the two first bodies.

Abstract: A low-power high-intensity lighting apparatus includes a lamp base, a lamp housing, and a lamp unit. The lamp base includes a parabolic reflector. The lamp housing is mounted on the lamp base, and includes a surrounding wall and an optical condenser. The surrounding wall has a first open end, and a second open end opposite to the first open end. The optical condenser is mounted on the lamp housing at the second open end. The lamp unit is mounted on the lamp base, extends into the lamp housing through the first open end of the surrounding wall, and generates light that propagates toward the parabolic reflector and that is reflected by the parabolic reflector toward the optical condenser.
