Abstract

A hand-held tool system comprises a hand-held tool and a positioning device matching the hand-held tool. The hand-held tool comprises an output shaft and a working head coupled to the output shaft. The positioning device comprises a detecting module configured to detect a positional feature and/or a movement feature of the positioning device and output a parameter indicative of the positional feature and/or the movement feature, the detecting module and the working head having a preset distance therebetween; a storage module configured at least to record reference position information about the working head; a control module configured to acquire real-time position information about the working head based on the parameter, the preset distance and the reference position information; and an output module configured to output the real-time position information in a way that can be perceived.

First claim

What is claimed is:

1. A hand-held tool system, comprising:
a hand-held tool;
and a positioning device couple to the hand-held tool;
wherein the hand-held tool comprises an output shaft and a working head coupled to the output shaft; and the positioning device comprises:
a detecting module configured to detect a position feature and/or a movement feature of the positioning device and output a parameter indicative of the position feature and/or the movement feature, the detecting module and the working head having a preset distance therebetween;
a storage module configured at least to record reference position information about the working head;
a control module configured to acquire real-time position information about the working head based on the parameter, the preset distance, and the reference position information; and
an output module configured to output the real-time position information in a sensible manner.

2. The hand-held tool system according to claim 1 , wherein the hand-held tool comprises a main body portion and a holding portion arranged at an angle to the main body portion, wherein the positioning device is disposed in the main body portion.

3. The hand-held tool system according to claim 2 , wherein the positioning device further comprises an input unit configured to input predetermined position information.

4. The hand-held tool system according to claim 3 , wherein the input unit is configured to be a key or a touch screen, and wherein the input unit is arranged on a tail end face of the main body portion which is opposite to the working head.

5. The hand-held tool system according to claim 2 , wherein the positioning device further comprises an actuating unit for actuating to record information of a determined reference position, wherein the actuating unit is disposed in the holding portion and adjacent to a switch trigger.

6. The hand-held tool system according to claim 2 , wherein the output module comprises a display screen for displaying position information of the working head in a digital manner.

7. The hand-held tool system according to 6, wherein the display screen is arranged on a tail end face of the main body portion which is opposite to the working head.

8. The hand-held tool system according to claim 1 , wherein the positioning device further comprises a mode selection unit configured to operably select the positioning device to be in a predetermined working mode, wherein the control module is configured to match an operation interface corresponding to the predetermined working mode.

9. The hand-held tool system according to claim 1 , wherein the output module comprises a reminding device, wherein the reminding device is controlled to send out an indication when the control module determines that the positioning portion is moved to a preset area adjacent to the predetermined position.

10. The hand-held tool system according to claim 9 , wherein the reminding device is controlled to send out an in-place indication when the control module determines that the positioning portion is reached to the predetermined position.

11. The hand-held tool system according to claim 1 , wherein the positioning device is provided with a DC power supply for supplying electric energy.

12. The hand-held tool system according to claim 1 , wherein the detecting module comprises an inertial detection unit for detecting an attitude angle of the positioning device, wherein the inertial detection unit is arranged parallel with or perpendicular to an axis of the output shaft of the hand-held tool.

13. The hand-held tool system according to claim 12 , wherein the inertial detection unit comprises an acceleration sensor and an angular velocity sensor, wherein the acceleration sensor is configured as a three-axis accelerometer and the angular velocity sensor is configured as a three-axis gyroscope.

14. The hand-held tool system according to claim 12 , wherein the detecting module further comprises an image sensing unit configured to detect a displacement of the positioning device, wherein the image sensing unit comprises a laser camera and a laser transmitter.

15. The hand-held tool system according to claim 1 , wherein the detecting module further comprises a laser ranging unit configured to detect a linear distance between the positioning device and a reference plane, wherein the laser ranging unit comprises a laser transmitter and a laser sensor.

16. The hand-held tool system according to claim 15 , wherein the laser ranging unit comprises a first laser unit and a second laser unit that are arranged perpendicular to each other.

17. The hand-held tool system according to claim 16 , wherein axis of the first laser unit and that of the second laser unit define a plane perpendicular to the axis of the output shaft of the hand-held tool.

18. The hand-held tool system according to claim 15 , wherein the laser ranging unit is rotatable about an axis.

19. The hand-held tool system according to claim 1 , wherein the hand-held tool comprises an interlock control circuit configured to initiate the hand-held tool or the positioning device working alternatively.

20. The hand-held tool system according to claim 1 , wherein the control module comprises a processing module configured to reset the reference position information.

21. A hand-held tool system, comprising a hand-held tool and a positioning device couple to the hand-held tool, wherein the hand-held tool comprises an output shaft and a working head coupled to the output shaft; and the positioning device comprises:
a detecting module configured to detect a position feature and/or a movement feature of the positioning device and output a parameter indicative of the position feature and/or the movement feature, the detecting module and the working head having a preset distance therebetween;
a communication module configured to communicate with an intelligent apparatus so as to obtain a predetermined position information from the intelligent apparatus;
a storage module configured at least to record reference position information about the working head;
a control module configured to acquire real-time position information about the working head based on the parameter, the preset distance, and the reference position information; and
an output module configured to give an indication based on the real-time position information and the predetermined position information.

22. The hand-held tool system according to claim 21 , wherein communication is performed between the communication module and the intelligent apparatus at least by means of one of Wi-Fi, Bluetooth, infrared, and NFC.

23. The hand-held tool system according to claim 22 , wherein communication information at least comprises one of position information, size information, image information, control instruction information, state monitoring information, and voice information.
