Abstract: A processing tool includes a long cutting portion with a connecting surface and at least one clamped portion which is fixed to the connecting surface. The long cutting portion extends along a longitudinal direction. Each of two sides of the long cutting portion along the longitudinal direction is an abutted end. A bottom portion of each of the abutted ends is connected to the connecting surface, and a top portion of each of the abutted end is away from the connecting surface. A first length is defined between the top portions of the abutted ends, and a second length is defined between the bottom portions of the abutted ends, wherein the first length is smaller than the second length. A processing tool assembly is provided as well. With such design, the processing tool thereof could be changed easily. Multiple workpieces could be simultaneously cut, and the accuracy thereof could be enhanced.

Abstract: A positioning system includes an image capturing device and a light-emitting microphone. When the microphone is working, a light emitting portion of the microphone emits light. The image capturing device captures an image of an area to include the light-emitting portion with an unadjusted capturing angle and focal distance and can adjusts the capturing angle and the focal distance to obtain an adjusted image. The light-emitting portion is to be located at a preset coordinated position in the target image before adjustments are made. The image capturing device captures images including a speaker at the microphone, applying an adjusting capturing angle and an adjusted focal distance. A positioning system is also disclosed.
