The grip portion 311 must descend only until the lower end portion of the grip portion 311 is positioned at the upper end of the mounting groove 14. This is because when the grip portion 311 descends over the mounting groove 14 excessively, It is possible to unnecessarily press the snap ring R mounted on the groove 14 and fixed in position to cause breakage and deformation of the snap ring R. [

However, since the present invention includes the control algorithm of the second driving unit 330 and the second driving unit 330 of the control unit 106, not only can the snap ring R be mounted accurately in the mounting groove 14, It is possible to prevent the snap ring R from being damaged or deformed due to the excessive fall of the roller 311.

Furthermore, the grip portion 311 or the lifting head portion 310 may further include a second sensing portion 104.
