The operator attaches the wiring box 4 to the pillar 900 by operating the operating portion 21 (trigger switch 314 ) of the power tool 1 and tightening the fixing screw 901 . The tightening torque of the fixing screw 901 at this time is measured by the measurement unit 23 . The control unit 10 stores the measurement result (tightening torque) of the measurement unit 23 in the storage unit 12 as one piece of construction information. Further, the acquisition unit 16 acquires position information when the operator operates the operation unit 21 of the power tool 1 . The control unit 10 stores the position information acquired by the acquisition unit 16 in the storage unit 12 as one piece of construction information.

In addition, the worker uses the external device 100 to input construction information such as the date of construction, the model number/ID of the power tool 1 used for construction, and the information of the operator to the input unit 15 . The control unit 10 stores the construction information input to the input unit 15 in the storage unit 12 .

The operator brings the power supply coil 111 of the power tool 1 closer to the power reception coil 811 of the wiring box 4 . As a result, power is supplied from the power supply unit 11 of the power tool 1 to the power receiving unit 81 of the wiring box 4 in a non-contact manner. In the wiring box 4 , when power is supplied from the power supply section 805 , the transmission section 802 transmits a radio signal including the material information pre-stored in the storage section 803 to the reception section 131 of the power tool 1 .

The operator searches for the wiring box 4 on the rear surface 92 side of the construction material 90 using the power tool 1 . Specifically, the operator moves the power tool 1 along the surface 91 of the construction material 90 . When the feeding coil 111 of the power tool 1 approaches the receiving coil 811 of the wiring box 4 , power is supplied from the feeding coil 111 to the receiving coil 811 . As a result, a radio signal is transmitted from the transmission section 802 of the wiring box 4, and the reception section 131 of the power tool 1 receives the radio signal, thereby causing the notification section 14 to generate a notification. This notification enables the operator to specify the position of the wiring box 4 . In other words, the power tool 1 also functions as a sensor for detecting the wiring box 4 arranged on the rear surface 92 side of the construction material 90 . Also, the receiver 131 of the power tool 1 receives the radio signal containing the material information, so that the operator can know the serial number, manufacturing number, product number, etc. of the detected wiring box 4 .

The worker forms a hole 93 (see FIG. 5B) corresponding to the opening 52 of the box body 50 of the wiring box 4 using an electric tool (for example, an electric cutter) different from the electric tool 1 . Then, the operator attaches the mounting frame 500 to the wiring box 4 by operating the operating portion 21 (trigger switch 314 ) of the power tool 1 to tighten the box mounting screws 550 . Construction information (second construction information) for attaching the mounting frame 500 to the wiring box 4 is stored in the storage unit 12 in association with the material information. Further, when the operator brings the power tool 1 closer to the wiring box 4, a wireless signal including the second construction information is transmitted from the transmitter 132 to the receiver 801, and the second construction information and the material information are stored in the storage unit 803. are linked and stored. Then, the worker attaches the wiring device 60 to which the electric wire 71 is connected and the plate 601 to the attachment frame 500 .

In the power tool 1 , the control unit 10 causes the output unit 17 to output the construction information (the first construction information and the second construction information) and the material information stored in the storage unit 12 to the external device 100 . Thereby, in the external device 100, it becomes possible to manage information in which construction information and material information are linked as management information.

In the second or third aspect, the power tool 1 according to the fourth aspect receives the wireless signal including the construction information stored in the storage unit 12 (second storage unit) in the receiving unit 801 (second 1 receiver) is preferably provided.

With the configuration described above, the power tool 1 can store construction information in the electrical facility material 40 . In addition, it is possible to collect material information and construction information stored in the storage unit 803 of the electrical facility material 40 even if the electrical tool is different from the electric tool 1 used for construction of the electrical facility material 40. . Note that the transmission unit 132 is not an essential component and may be omitted.

The embodiment described above is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiments, and various modifications can be made in accordance with the design, etc., as long as they do not deviate from the technical idea of the present invention. Of course, changes are possible.
