This arrangement enables the gripping block 215 to be dialed during the rotation of the second rotating member 213, so that the gripping block 215 can slide in the radial direction of the first rotating shaft. Optionally, the sliding groove 2131 is disposed on the second rotating member 213, and the sliding block is disposed on the clamping block 215. This arrangement effectively reduces the volume of the clamp block 215, and the slide groove 2131 is provided in the second rotor 213, thereby effectively utilizing the structure of the second rotor 213.

In this embodiment, taking the view shown in fig. 2 as an example, when the first rotating shaft rotates counterclockwise from top to bottom, the clamping block 215 clamps the pen barrel 100.

Specifically, three clamping blocks 215 are arranged, and are arranged in the axial direction of the first rotating shaft at intervals, and each clamping block 215 is provided with a sliding block; three slide grooves 2131 are also provided. Of course, in other embodiments, the number of the clamping blocks 215 and the sliding grooves 2131 may be 4, 5, 6, 10, or other numbers. The number of the sliding grooves 2131 is equal to or greater than the number of the clamping blocks 215.

In addition, in this embodiment, the sliding groove 2131 may be linear, and this arrangement makes the design and manufacturing process simple and low in cost. In other embodiments, the sliding slot 2131 may also be an arc, and the arc structure can control the sliding speed of the clamping block 215 during the uniform rotation of the second rotating member 213.

Furthermore, the sliding block is provided with rolling wheels, and the rolling wheels can roll along the inner wall of the sliding groove 2131. This arrangement reduces friction and increases the speed of the reaction of the clamping blocks 215.

Wherein a coupling is provided between the second docking portion 2175 and the second driver 23. This arrangement is such that when the barrel clamping assembly 21 is rotated above the second driving member 23 during rotation of the rotary table 12, the lifting driving member 2174 drives the lifting portion 2173 to move from the second position to the first position so that the second docking portion 2175 and the first docking portion 2171 are docked, thereby enabling the second driving member 23 to drive the first rotary shaft to rotate. This arrangement reduces the number of second driving members 23, reducing the cost of the apparatus.
