Claim 0:
1. A quick measurement module, comprising:
a stationary seat having a stationary seat body and a first reference plane and a second reference plane provided individually on the stationary seat body and extending linearly along a virtual shifting axis, the first reference plane and the second reference plane being spaced apart by an included angle;
a movable seat capable of linear displacement along the axial direction of the shifting axis within the extension range of the first reference plane and the second reference plane;
a first distance sensing unit secured to the movable seat and having a first sensing direction oriented towards the first reference plane, configured to sense the distance from the first reference plane, the first distance sensing unit has a photosensor, the photosensor is a laser locator;
a second distance sensing unit secured to the movable seat and having a second sensing direction oriented towards the second reference plane, configured to sense the distance from the second reference plane;
a position sensing unit configured to sense the position of the movable seat during its movement along the shifting axis; and
a rectification mechanism bridged between the stationary seat body and the movable seat, configured to ensure stability of the movable seat during movement;
whereby when the movable seat is moved linearly along the shifting axis, the first distance sensing unit and the second distance sensing unit sense respectively the distances of the movable seat from the first reference plane and second reference plane during its displacement so as to acquire the linearity accuracy of the movable seat in movement and have it combined with the position information provided by the position sensing units so as to acquire the repetition accuracy of the movable seat;
wherein the first distance sensing unit, the second distance sensing unit, and the rectification mechanism are connected to the moveable seat.
