The number of the pen rotating bosses 1081 of the pen rotating mechanism 10 is matched with the number of the installation cavities.

The supporting seat 20 is matched with the pen rotating mechanism 10, the supporting seat 20 comprises a second connecting part 201 matched with the first connecting part 107, the second connecting part 201 is a vertically arranged connecting mechanism, a groove 2011 for accommodating a first connecting arm 1072 is arranged on one side of the second connecting part 201, the inner surface of the groove 1072 is matched with the outer surface of the first connecting arm in shape, and a circular curved surface is selected in the embodiment. Since the first connecting arm 1072 is engaged in the groove 2011, the pen-changing mechanism 10 rotates relatively to the supporting base, thereby completing the lifting and dropping actions of the pen-changing mechanism 10.

Since the working platform of the pen replacing mechanism may have a plane error when the pen is lifted or dropped, the first adjusting mechanism 30 is provided to eliminate a problem that the pen replacing mechanism 10 encounters a rugged working platform, and can achieve a small position adjustment of the pen replacing mechanism, specifically, the first adjusting mechanism 30 includes a connecting shaft 301 provided on both sides of the first connecting arm 1072 and a long groove 302 provided on the second connecting portion 201 and used for mounting the connecting shaft, both ends of the long groove are arc-shaped (in this embodiment, long circular), and the distribution direction of the long groove 302 is vertically distributed.

similarly, when the pen needs to be dropped, the first shell rotates relative to the second shell under the driving of the power device to drive the pen-changing boss fixed at the top end of the first shell to rotate, at the moment, the rotating bearing is driven to rotate simultaneously when the pen-changing boss rotates, the pen-changing groove adjacent to the pen-changing boss is abutted against the rotating bearing, so that the distance from the pen core to the working platform is reduced, and the first connecting arm of the pen-changing mechanism rotates relative to the groove on the second connecting part to realize the pen-dropping of the pen-changing mechanism;

when the color of the pen core does not need to be changed during the work of the pen changing mechanism, the power mechanism drives the first shell to rotate, and when the pen lifting action is completed, the power mechanism rotates, so that the same pen rotating groove continuously abuts against the rotating bearing, and the pen falling is completed;

when the pen changing mechanism works without selecting the colors of the pen cores, the pen cores with the same or different colors can be arranged in the mounting cavity, and the power mechanism drives the first shell to rotate, so that the pen changing groove and the pen changing boss continuously rotate in a certain direction, and the pen cores can be changed simultaneously by lifting one pen and dropping one pen, and the changed pen cores can be in the same color or different colors.
