Abstract: A structure of an electrical tool is disclosed. The electrical tool comprises a housing mounted with a driving device for coupling with a tool connector, and having a control switch for controlling the switching of the driving device, characterized in that a compartment for containing a power source device is provided to the housing, and one side of the housing is positioned with a battery cover for easy replacement of the power source device, and one side of the housing is a protruded button for slidably mounting onto a belt clip, and the driving device is a gear module with a motor to drive the gear module, and one side of the gear module is provided with a tool mount extended beyond the external of the housing for the coupling of the tool connector, and the tool connector is secured with a positioning gear and the housing is mounted with a positioning block for engagement with the positioning gear, and one end of the positioning block is protruded at the external side of the housing.

Abstract: A sample and tool displaying board is disclosed, and comprises (a) a board body having a plurality of engaging slots thereon; (b) a plurality of fastening clips, having a top clipping member and a pair of engaging posts, having a spherical body at the top end thereof, being mounted at the bottom thereof, and said fastening clips being mounted onto said board body; (c) a securing strap being formed between two fastening clips and being secured by the clipping member, and said engaging posts being mounted within said engaging slots, thereby a sample or a tool is secured onto the displaying board by said securing strap. The engaging slot has a round hole at one end of the slot, and an elongated slot extension from one end to the round hole such that the engaging posts can be inserted into the engaging slots and secured thereon. The present displaying board provides easy and convenient displaying for samples and tools, or arrangement of the displayed samples and tools.

Abstract: A palm-top fabric leading edge detector adapted to be incorporated in a high temperature or regular temperature, L-configured or U-configured dyeing machine includes a detector body which is releasably connected to a sensor mounted in the dyeing machine via a cable to receive a fabric leading edge detection signal from the sensor when the leading edge of a fabric that is moved through the dyeing machine for dyeing passes through the sensor. The detector processes the fabric leading edge detection signal and provides the detection result on a display on the detector body. The detector is driven by an internal power source which may be primary cells or secondary cells rechargeable by means of external power source. Visual indicator and audio signal generation device are provided to indicate the detection of the fabric leading edge in a visual and audio manner.
