Embodiment 1
[0037] combine figure 1 , a pencil for replacing different types of refills in this embodiment, including a pen cap 16, a pen case 18, a pen tube 6 and a pen head 19, inside the pen case 18, a core storage device is provided near the end of the pen cap 16 , the core storage device inputs different lead cores 8 into the pen tube 6 by rotating; one end near the nib 19 is provided with a core-out device and a core-returning device, and the core-out device moves the lead core 8 from the pen tube 6 To the nib 19, the core returning device makes the lead 8 move back into the pen tube 6 from the nib 19. This embodiment overcomes the disadvantages that the existing pencils store the lead cores 8 together, which are easy to jam and cannot accommodate different soft and hard types of lead cores 8, and also overcome the inconvenience of manually replacing the lead cores 8 at the tip of the pen. The structural design of the core storage device, the core output device and the core return ...

The invention discloses a method for replacing different models of pencil refills, and belongs to the technical field of stationery. A pencil refill storage device is arranged at the end, close to a pencil cover, of a pencil, and the different pencil refills are input into a pencil tube by rotating the pencil refill storage device; a pencil-refill-out device and a pencil-refill-return device are arranged at the end, close to the a pencil point, of the pencil, and the pencil-refill-out device makes the pencil refills be moved out from the pencil tube towards the pencil point, and pencil-refill-out operation is finished; and the pencil-refill-return device makes the pencil refills be moved from the pencil point back into the pencil tube. According to the method for replacing the different models of pencil refills, the problem that in the prior art, the pencil refills are stored together in a pencil, jamming is prone to occurring, different hardness models of pencil refills cannot be accommodated in one pencil is solved, the defect that manual replacing of the pencil refills at the pencil point is troublesome is overcome, the task of pencil refill returning and replacing can be finished in the pencil tube, and the method has the characteristics of simple structure, one pencil with multiple pencil refills, internal pencil refill replacing and wide application range.
Description
technical field [0001] The invention relates to the technical field of stationery, and more specifically relates to a method for replacing pencil refills of different models. Background technique [0002] Pencils play a big role in daily study and work. At present, there is a pencil that can automatically core out on the market, which brings great convenience to users. However, the lead cores of this mechanical pencil are all stored in the pen tube. After the core is used up, the lead core is easy to get stuck together during the core extraction process, resulting in failure to normally extract the core. It is also possible to take out the lead core from the core storage tube and then pack it into the nib, but the operation of loading the core is inconvenient, time-consuming and laborious. [0003] At the same time, pencils are the main tools in engineering drawing and art work, and are widely used because of their variety and complete specifications. But among existing ma...
