A touch trigger probe is used to determine whether contacts with a workpiece and contains a sleeve, a sensing segment and a transmitting segment. The sleeve extends along an axial direction and includes a first chamber and a second chamber communicating with the first chamber. The sensing segment includes a sensing end extending out of the sleeve and a driving end far from the sensing end. The transmitting segment is pushed by the driving end to move in the second chamber to a triggering position from an original position relative to the sleeve, and includes a driven end protruded axially and capable of contacting with the driving end. Thereby, as the touch trigger probe of the invention has a swing sensing travel for lateral contact and an elevation sensing travel for longitudinal contact, excessive sensing elements can be avoided to lower production costs and obtain positioning precision.
