When the adapter shaft 61 rotationally moves downward linearly, the outer wall of the adapter shaft 61 abuts against the end of the locking member 64 to compress the elastic member 66, so that the locking member 64 contracts along the radial direction of the adapter shaft 61 to avoid, so that the adapter shaft 61 moves downward continuously, until the end of the limiting member 63 slides to the closed end of the first straight groove 611a when the adapter shaft 61 moves, the locking part 61b of the adapter shaft 61 just rotates to be opposite to the locking member 64, and the locking member 64 is clamped in the locking part 61b under the restoring force of the elastic member 66, so that the adapter shaft 61 is fixed from both ends to be not moved and rotated, and the pressing member 20 is kept in the state of abutting against the pen cap 203. When the adapter shaft 61 is driven by the pushing member 30 to rotate and move linearly upward, since the locking member 64 has an arc-shaped engaging end and the corresponding locking portion 61b also has a certain curvature, the elastic member 66 is compressed under the action of the pushing force, the locking member 64 can be disengaged from the engaging with the locking portion 61b, until the adapter shaft 61 moves to the closed end of the second straight groove 612a when the end of the limiting member 63 slides to the closed end of the second straight groove 612a, the pressing member 20 releases the pressing force on the cap 203 to reset, and the locking member 64 also moves outward to reset under the restoring force of the elastic member 66.

Further, an elastic member 67 may be disposed between the adapting shaft 61 and the mounting base 10 or between the adapting shaft 61 and the fixing member 62, and the elastic member 67 constantly drives the adapting shaft 61 to move linearly toward the direction of engaging with the locking member 64.
