wherein, the extension power cord electrically connects to a power unit which converts a supply power to an output power for outputting to the USB jack, and the main body has an accommodating section for receiving the USB jack.
2. A detachable electrical power receptacle, comprising:
a main body, having an electrical power plug for connecting a power supply source and having at least one electrical outlet assembly;
at least one extension socket; and
at least one extension power cord, electrically connected to the extension socket;
wherein, the extension power cord electrically connects to a power unit which converts a supply power to an output power for outputting to the extension socket, and the main body has an accommodating section for receiving the extension socket.
3. A detachable electrical power receptacle, comprising:
a main body, having an electrical power plug for connecting a power supply source and having at least one electrical outlet assembly;
at least one extension socket; and
at least one extension power cord, connected between the extension socket and the main body;
wherein, the main body outputs an output power to the extension socket by ways of the extension power cord and the extension socket is either disengaged from the main body or engaged to a potion of the main body.
4. The detachable electrical power receptacle according to claim 3, wherein the main body further includes:
a first housing member; and
a second housing member, being coupled to the first housing member to form the main body and disposing an outlet hole on the first housing member or the second housing member.
5. The detachable electrical power receptacle according to claim 3, further including a coil reel, being disposed inside the main body for winding the extension power cord so as to manage a distance between the main body and the extension socket as the extension socket is in an exposed mode.
6. The detachable electrical power receptacle according to claim 3, further including a coil reel, being configured between the extension socket and the main body for winding the extension power cord so as to manage a distance between the main body and the extension socket as the extension socket is in an exposed mode.
7. The detachable electrical power receptacle according to claim 3, wherein the extension power cord is exposed out of the main body and the extension socket.
8. The detachable electrical power receptacle according to claim 3, wherein the extension power cord electrically connects to a power unit which converts a supply power to the output power for outputting to the extension socket.
9. The detachable electrical power receptacle according to claim 3, further including a charging cradle, having a binding section which is coupled to the extension socket.
10. The detachable electrical power receptacle according to claim 7, wherein the charging cradle is formed by a bendable thin plastic sheet or a bendable thick paper.
11. The detachable electrical power receptacle according to claim 3, wherein the main body further includes an accommodating section which is designed for receiving the extension socket.
12. The detachable electrical power receptacle according to claim 3, wherein the main body further includes:
a power switch, for controlling a supply power outputting to the main body; and
an indicator, for representing the power supply source is in a conduction mode or in a cutoff mode.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A grinding machine for grinding material, comprising a grinding head having an axial bore defining an upstream end and a downstream end, wherein the axial bore has a plurality of flutes extending between the upstream end and the downstream end, wherein each flute defines a spiral groove extending in the upstream-downstream direction, and wherein a dimension of at least some of the flutes is variable along the length of the flute, wherein the variably dimensioned flutes are configured to define an increase in the width of the spiral groove in the upstream-downstream direction to define a divergent flow path for the material as it is advanced within the bore toward the downstream end of the bore.
2. The machine of claim 1, wherein the flutes are cast into the head.
3. The machine of claim 1, wherein the flutes are dimensioned such that the spiral groove generally increases in overall height in the upstream-downstream direction.
4. The machine of claim 1, wherein the grinding head has an increased diameter bell portion at the downstream end of the axial bore, and wherein the spiral grooves defined by the flutes extend from the bore into the increased diameter bell portion of the grinding head.
5. The machine of claim 4, wherein the spiral grooves defined by the flutes are dimensioned to generally increase in transverse width across the increased diameter bell portion of the grinding head.
