[0004]

The main purpose of this creation is to provide an electric screwdriver with a pressure sensor.

[0005]

In order to achieve the above object, the present invention provides an electric screwdriver including a grip, a rotating collet, and a pressure sensor. The rotary chuck is disposed at one end of the grip and is rotatable relative to the grip, and the pressure sensor is disposed on the outer surface of the grip.

[0006]

Preferably, the aforementioned electric screwdriver further accommodates a drive motor disposed within the grip, and the drive motor is coupled to the rotary chuck and drives the rotary chuck to rotate. The aforementioned electric screwdriver may further comprise a coating covering the outer surface of the grip and covering the pressure sensor.

【0007】

Preferably, the aforementioned electric screwdriver further comprises a monitoring module disposed on the electric switch and electrically connected to the pressure sensor. The monitoring module can include a light emitting element and a control unit electrically connected to the pressure sensor and the light emitting element. The monitoring module can also include a sounding element and a control unit that electrically connects the pressure sensor and the sounding element. The monitoring module can also include a display and a control unit electrically connected to the pressure sensor and the display

[0008]

The electric screwdriver of the present invention can measure the gripping force applied by the user to the grip by the pressure sensor provided on the grip, thereby adjusting the gripping force of the user for reference.

[0013]

Referring to FIG. 1 and FIG. 2 , a first embodiment of the present invention provides an electric screwdriver including a grip 100 , a rotating collet 200 , a driving motor 300 , a pressure sensor 400 , a monitoring module 5000 , and A cladding layer 600.

[0014]

The grip 100 is preferably a cylindrical hard hollow rod. In the present embodiment, the grip 100 is preferably cylindrical, but it is also an L-shaped hollow rod. . The grip 100 can be made of plastic or metal. The creation does not limit the shape and material of the grip 100.

[0015]

The rotary chuck 200 is disposed at one end of the grip 100 and is rotatable along the axial direction of the grip 100 for holding a drill tail or a sub-head 10 together.

[0016]

The drive motor 300 is housed within the grip 100 and is secured to the grip 100 that connects the rotary collet 200 and drives the rotary collet 200 to rotate relative to the grip 100.

[0017]

The pressure sensor 400 is disposed on an outer surface of the grip 100. The monitoring module 5000 is disposed on the grip 100. In this embodiment, the monitoring module 5000 includes a control unit 510 and a light emitting component 520. The light-emitting element 520 is exposed on the outer surface of the handle 100, and is electrically connected to the control unit 510 and can be driven by the control unit 510 to emit light. In this embodiment, the light-emitting element 520 can be a light-emitting diode, but the present invention does not This is limited. The control unit 510 is electrically connected to the pressure sensor 400 for receiving the pressure data measured by the pressure sensor 400.

[0018]

In this embodiment, the cover layer 600 is preferably a soft sheet, which may be made of silicone or rubber. The present invention is not limited thereto. The cover layer 600 is preferably attached to the outer surface of the grip 100 and covers the pressure sensor 400. The cover layer 600 can also be formed in a cylindrical shape and sleeved on the grip 100 and cover the pressure sensor 400, but Creation is not limited to this.

[0019]

When the user holds the electric screwdriver operating the creation, the grip force of the user presses the pressure sensor 400, and the pressure sensor 400 measures the pressure data of the user's grip. The control unit 510 has a predetermined pressure interval. When the pressure data received by the control unit 510 reaches a predetermined pressure interval, the control unit 510 drives the illumination unit to emit light, thereby informing the user that a better grip force has been applied.

[0020]
