After the force applied to the control member 351 is removed, the control member 351 is driven by the pushing spring 353 to reset, so that the magnetic attraction effect between the control member 351 and the pushing member 355 is released, and the pushing member 355 is pushed by the pushing spring 353 to push against the external part again. Therefore, the clamping or releasing effect between the sleeve 100 and the external component can be simply and directly achieved by applying force to the control member 351, so as to facilitate the taking and placing of the calibration platform and the adjustment of the orientation angle.

In some embodiments, referring to FIG. 5, a threaded portion 330 is disposed within the sleeve 310, the threaded portion 330 being threadably coupled to an end of the cannula 100.
