Abstract: Disclosed are encoding and decoding methods for 2D barcodes, and an electronic device. During the encoding, the electronic device obtains a 1D barcode, captures a horizontal image of the 1D barcode, and encodes the horizontal image, with/without a literal data, a numerical data or a combination thereof into a 2D barcode. During the decoding, the electronic device obtains the 2D barcode, and decodes the 2D barcode into a 1D barcode with/without a literal data, a numerical data or a combination thereof. Thus, more data can be written in the 2D barcode but an image data of the 2D barcode will not be too large. The electronic device can quickly transmit the 2D barcode to another electronic device without any optical device to capture the 2D barcode for decoding it into a 1D barcode with/without a literal data, a numerical data or a combination thereof.

Abstract: A power tool having a depth adjustment mechanism includes a motor housing, a support base for supporting the motor housing, and a depth adjustment member coupled to the support base and movable between two positions. The depth adjustment member in a first position contacts a surface portion of the motor housing and in a second position is distanced from the surface portion of the motor housing such that the movement of the depth adjustment member from the first position to the second position is in a direction parallel to a plane that is substantially tangent to the surface portion of the motor housing.
