Abstract: A self-adjusting level for determining the leveling between two distant points is disclosed. It mainly contains a main body and a light beam indicator. The main body contains a flame having two oppositely disposed supporting arms, a disc-like base disposed below said main body, and a 360-degree rotatable graduated angle-measuring disc disposed between said base and said frame. The light beam indicator includes: (a) an outer ring rotatably connected to and between said two supporting arms of said frame of said main body via two outer ring shafts so that said outer ring is allowed to freely rotate about said outer ring shafts, (b) an inner shaft being rotatably connected at both ends thereof to said outer ring and extending along a diameter of said outer ring so as to rotate in a direction normal to a rotating direction of said outer ring, (c) at least one light beam generator disposed inside said inner shaft for generating at least one light beam which emits from at least one end of said inner shaft, and (d) a plummet hanging from a central recess formed on said inner shaft. The plummet is provided with a battery means in an internal portion thereof to supply power to said light beam generator without affecting a motion of either of said inner shaft or said outer ring.

Abstract: An improvement in a drawer lock of a cabinet includes a cylinder, a trigger bar, a fixing block, a sliding block, a latch hook, a first elastic member and a latch mechanism. The latch mechanism has a clutch pivotally engaged with a latch bar. A second elastic member keeps the clutch to be engaged with the latch bar at a preset angle. The latch hook of a closing drawer can wedge the latch bar to turn an angle smoothly while the clutch and the sliding block remain stationary, so as to prevent causing any damage to the latch hook even when the cabinet is in a locked position.

Abstract: A vibration and noise reducing workbench structure is disclosed. The workbench is a multiplayer structure comprising a metal board, a cushioning layer and a wooden layer stacked upon each other. The metal board is disposed at the top, and the cushioning layer is sandwiched between the metal board and the wooden layer. The presence of a cushioning layer can effectively absorb the vibration and accompanying noise transmitted from the top-layer metal board. As such, lightweight and thinner metal board can be used to lower the production cost and the weight of the entire workbench structure, and the handling of workbench is made easier with the use of less manpower, thereby reducing industrial accidents and costs.
