Abstract: A power hand tool includes a housing that houses a motor, a transmission gear set, a torque control mechanism and an impact mechanism. The torque control mechanism has an adjustment device that is movable between a first position and a second position inside the housing by a rotation action to set a predetermined output torque of the power hand tool. The output torque of the power hand tool is at the minimum condition and the adjustment device stops the impact mechanism from working to prevent destruction to the torque setting of the power hand tool when the adjustment device is in the second position.

Abstract: A flashlight includes a main member having top, a bottom, a front and a rear. The main member has a base a head and battery pack, wherein the head is pivoted on the base via a pivot to be flexed to the front. A first light source and a second light source are mounted on the head, wherein the second light source projects light that is substantially to that of the first light source. A hook is provided in a tunnel in the base to be drawn out or pushed into. The first and second light sources and the flexion of the head provide a greater illumination range and a function of adjusting the illuminating direction when it is hung.

Abstract: A saw blade clamping mechanism includes a holder connectable to a reciprocating shaft of a power sawing tool. The holder has a sliding way, a receiving slot for insertion of a saw blade, and a through hole in communication between the sliding way and the receiving slot. A steel ball is movably installed in the through hole. A sliding block is mounted in the sliding way and moveable between a first position for receiving the steel ball for removal of the saw blade out of the receiving slot and a second position to force the steel ball into the receiving slot to lock the saw blade. A spring member supports the sliding block in the second position. A control knob is connected to the sliding block for operation by the user to move the sliding block from the second position to the first position.

Abstract: An adapter for an electric/pneumatic impact rotary tool includes a first body and a second body. The first and second bodies are cylindrical and coaxial with each other. The first body has a square coupling hole for coupling a cuboid output end of the impact rotary tool. The second body has a screw hole and an external thread, which is located on an outer periphery of the second body and is converse in direction to a thread of the screw hole, for coupling a tool.

Abstract: A dual-sectional monitor signal transmission module for Wireless Tire Pressure Monitoring Systems. On one side of this monitor signal transmission module, an air tap is designed, which can be assembled and fixed in the hole of the tire rim. This Monitor Signal Transmission Module and the air-tap are a dual-sectional combination to allow the air-tap to be fittingly snapped into the hole on the tire rim. Moreover, a mounting seat is designed on the Monitor Signal Transmission Module at the end where the air-tap is to be positioned so that the air-tap and the outer-end of the mounting seat can be connected in a counter-screw setup. The Monitor Signal Transmission Module can be easily detached with just a simple step of unscrewing the air-tap when replacing tires.

Abstract: A power hand tool includes a housing, a chuck mounted in one end of the housing for holding a tool bit, a driving device mounted in the housing and coupled to the chuck for rotating the tool bit, and a light projector mounted in the housing for projecting a plane of light toward the extending direction of the tool bit to form a line of light on a working surface to be processed by the power hand tool.

Abstract: An adapter for connecting between an output head of an impact rotary tool and a tool bit includes a body, which has a first end wall, a second end wall opposite to the first end wall, a square hole axially extending from the first end wall toward the second end wall for coupling to the output head of the impact rotary tool, and a hexagonal hole axially extending from the second end wall toward the first end wall in alignment with the square hole for holding the tool bit, and a magnet mounted inside the body adjacent to the hexagonal hole for securing the tool bit in the hexagonal hole by magnetic attraction.

Abstract: A shell structure for Wireless Tire Pressure Transmission Devices. The internal part of this shell is a space provided for installation of a Wireless Tire Pressure Transmission Device and the bottom part of the shell is a fixture dimension which enables attachment of the Wireless Tire Pressure Transmission Device onto the surface of the tire-rim. On the two ends of the shell, wire-holes are designed to provide for wire-fixing. The fixture dimension on the bottom of the shell, viewed from the cross-section, is designed in a slanting dimension. Or, the wire-holes of the shell can be designed to form a slanting angle to replace the above-stated slanting dimension of the shell-fixing surface.
