[0028] In this embodiment: the fixing unit comprises a support seat 101, on which four placement seats 102 are evenly arranged, and the placement seats 102 on the support seat 101 are used to place the pen holder;

[0029] In this embodiment: the pushing unit includes a pushing seat 201, a support plate 202 is arranged behind the pushing seat 201, an electric push rod 203 is installed on the top of the support plate 202, a push plate 204 is arranged at the extended end of the electric push rod 203, four pushing rods 205 are evenly arranged on the push plate 204, two limit rods 206 are symmetrically arranged on both sides of the electric push rod 203, the support plate 202 is welded to the pushing seat 201, and the support plate 202 is L-shaped. The pushing seat 201 supports the electric push rod 203 to extend through the support plate 202, driving the pushing rod 205 on the pushing plate 204 to move forward along the limit rod 206, and pushing the pen core in front of it into the pen holder;

[0030] In this embodiment, the unloading unit includes a refill bin 301, a guide tube 302 is installed below the refill bin 301, four adjustment plates 303 are slidably installed in the guide tube 302, two connecting rods 304 are symmetrically arranged on the front and rear sides of the four adjustment plates 303, a slider 305 is arranged in the middle of the connecting rod 304, a screw rod 306 is arranged on the slider 305, a synchronous wheel 308 is arranged at one end of the screw rod 306, a synchronous belt 309 is installed between the two synchronous wheels 308, a knob 307 is arranged at the end of the screw rod 306 away from the synchronous wheel 308, and a friction pattern is arranged on the surface of the knob 307. The pen core is placed in the pen core bin 301, and the pen holder is placed in the placement seat 102 on the support seat 101. The pen core at the bottom of the pen core bin 301 is dropped through the gap between the guide tube 302 and the adjustment plate 303. When the size of the pen core changes, the knob 307 is rotated to rotate the front screw rod 306, which drives the rear screw rod 306 to rotate synchronously through the synchronous wheel 308 and the synchronous belt 309, and pushes the slider 305 to drive the connecting rod 304 to synchronously drive the four adjustment plates 303 to move along the screw rod 306 from the front and rear sides, so as to change the gap between the adjustment plate 303 and the guide tube 302 to meet the needs of pen cores of different sizes.

[0031] In this embodiment: the limiting unit includes a limiting seat 401, four limiting blocks 402 are slidably installed in the limiting seat 401, and an adjusting rod 403 is arranged under the four limiting blocks 402.
