The present invention discloses an elasticity detecting probe, the elasticity detecting probe comprises a probe body and a control switch for controlling on/off of the probe body, wherein the probe body and the control switch are separately arranged and the probe body and the control switch are coupled to each other electrically or wirelessly. The separate arrangement of the probe body and the control switch, allows that an operator can operate the control switch to turn on/off the probe body by using other body parts rather than the two hands, thereby preventing the offset of the probe body while turning on the control switch, and improving the detection accuracy.
