Abstract

The present disclosure provides a portable power tool. The power tool includes a tool body, a tool assembly and a gas pressure detection assembly. The tool assembly includes a tool bit furnished detachably in an end of the tool body. The gas pressure detection assembly is furnished detachably in another end of the tool body. The gas pressure detection assembly is communicatively coupled to the tool body.

Claims

1. A portable power tool, comprising:

a frame disposed at one distal end of the portable power tool, the frame internally housing a power transmission assembly comprising a motor and a reducer;

a tool assembly including a single bit detachably disposed at a distal end of the frame, the single bit coupled to the reducer; and

a gas pressure detection assembly detachably disposed at the other distal end of the portable power tool opposite the single bit, the gas pressure detection assembly communicatively coupled to the frame;

wherein, a gear set in the reducer is locked and unable to rotate while the power transmission assembly is unpowered.

2. The portable power tool of claim 1, the frame further internally housing a case and a containing space;

wherein, the power transmission assembly and the containing space are respectively disposed in an interior of the case;

wherein, one or more additional bits compatible with the reducer are stored in the containing space.

3. The portable power tool of claim 2, wherein the frame further comprising:

a first energy storage element, furnished inside the case at a position between the power transmission assembly and the containing space, the first energy storage element transmitting electricity to the power transmission assembly.

4. The portable power tool of claim 3, wherein the first energy storage element is a rechargeable battery.

5. The portable power tool of claim 3, wherein the first energy storage element receives power from an USB device when externally connected thereto.

6. The portable power tool of claim 2, further comprising:

a first control element; and

a second control element;

wherein, the first control element and the second control element are furnished respectively on the exterior of the frame for enabling the first control element and the second control element to activate the power transmission assembly to rotate accordingly and thus to drive the tool assembly to rotate clockwise or counterclockwise, respectively.

7. The portable power tool of claim 6, further comprising:

a display element, furnished on the frame proximal to the first control element and the second control element;

wherein the display element receives a detection data from the gas pressure detection assembly and displays the detection data on the display element.

8. The portable power tool of claim 7, further comprising:

a lighting element, furnished on the frame at a position next to the tool assembly; and

a third control element, furnished on the frame, for turning the lighting element on or off.

9. The portable power tool of claim 8, wherein the lighting element is a device selected from the group consisting of:

a light emitting diode (LED) device, a tungsten lamp, and a halogen lamp.

10. The portable power tool of claim 2, wherein the single bit is a bit selected from the group consisting of:

a slotted screwdriver bit, a crosshead screwdriver bit, a hex key wrench, and a star key wrench.

11. The portable power tool of claim 2, wherein the motor is coupled to the reducer while the reducer is coupled to the single bit.

12. The portable power tool of claim 2, wherein the frame is made of a material selected from the group consisting of:

a metal, a plastic, a composite material and an organic material.

13. The portable power tool of claim 1, wherein the gas pressure detection assembly is fixed to the frame by a coupling element.

14. The portable power tool of claim 1, wherein the gas pressure detection assembly further comprising:

a shell;

a gas pressure detector, furnished inside the shell;

a gas nozzle, connected to an end of the gas pressure detector;

a gas inlet element; and

a gas control element, connected to an end of the gas pressure detector such that the gas control element is spaced from the gas inlet element by a distance.

15. The portable power tool of claim 14, wherein the gas pressure detector is a device selected from the group consisting of:

an electronic pressure sensor chip and a mechanic pressure sensor device.

16. The portable power tool of claim 14, wherein the gas inlet element is connected to a gas supply by one end and the gas control element controls the amount of gas passing through the gas inlet element.

17. The portable power tool of claim 14, wherein the gas inlet element is made of a material selected from the group consisting of:

an aluminum alloy, iron, stainless steel and galvanized iron.

18. The portable power tool of claim 14, wherein the shell is made of a material selected from the group consisting of:

a metal, a plastic, and a composite material.

19. The portable power tool of claim 18, wherein the metal can be an aluminum alloy, iron, stainless steel, or cast iron;

and the plastic can be ABS, PC, PP or PS.

20. The portable power tool of claim 14, wherein the gas pressure detection assembly further comprising:

a second energy storage element, furnished inside the shell for providing power to the gas pressure detector.
