[0025] In order to deepen the understanding of the utility model, the utility model will be further described in detail below in conjunction with the drawings and examples, which are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.
[0026] Embodiment
[0027] As Figure 1 Indicated, a multipurpose drawing pen, including pen holder and a plurality of pen cartridge 2;The inside of the pen holder is detachably provided with refill 3;The pen cartridge 2 includes the inner hole 4 that the shaft center is through, the pen holder passes through the inner hole 4 and connects each pen cartridge 2, the lateral wall of the pen cartridge 2 is provided with the clamping structure that the pen cartridge 2 axial limit is arranged at both ends respectively;The pen cartridge 2 is axially distributed with a plurality of core holes 5 at the periphery of the inner hole 4, the core hole 5 is inserted with the refill 3.
[0028] The pen holder of the scheme is used as normal pen, and the pen cartridge 2 connected in series on the pen holder is used as storage spare refill 3, and the refill 3 placed in the core hole 5 of the pen cartridge 2 can be replaced with the refill 3 in the pen holder. Since the pen holder can be provided with a plurality of pen cartridges 2, and the pen cartridge 2 is provided with a plurality of core holes 5, in fact, a pen can carry a large number of refills 3, and more pens can be selected during drawing, and all refills 3 are arranged in the pen cartridge 2 and the pen holder, so that carrying and replacement are very convenient.
[0029] The pen holder includes main rod 1 and pen head 8, the front end of the main rod 1 is provided with the inner cavity for storing the refill 3, the pen head 8 is provided with the front hole for the front end of the refill 3 to pass through, and the pen head 8 is rotationally connected with the front end of the inner cavity. The refill 3 can be replaced more conveniently.
[0030] The clamping structure includes the boss arranged on the lateral wall of the front end of the pen holder and the nut pressure ring 9 threadedly matched with the rear end of the pen holder. The pen cartridge 2 can be axially limited from front to back.
[0031] The nut pressing ring 9 and the pen cartridge 2 are provided with elastic members. The elastic members can limit the pen cartridge 2 in the axial direction and provide a certain movement space for the pen cartridge 2. The pressing plate 11 is arranged between the elastic members and the pen cartridge 2 to prevent the pen core 3 from sliding out of the pen cartridge 2.
[0032] The elastic members are springs 10 which are sleeved on the pen barrel. The overall structure is more stable.
[0033] The end face of the pen cartridge 2 is provided with a plurality of positioning grooves 6 which are uniformly distributed on the same circle diameter. The other end face of the pen cartridge 2 is provided with an arc convex which corresponds to one of the positioning grooves 6. The positioning grooves 6 and the arc convex can determine the positions of the adjacent pen cartridges 2, and the arc convex and the elastic members can smoothly rotate the adjacent pen cartridges 2 when the adjacent pen cartridges 2 are forcibly rotated.
[0034] One of the positioning grooves 6 is arranged between the two adjacent core holes 5. The adjacent pen cartridges 2 are better positioned.
[0035] The pressing plate 11 is provided with an arc convex which corresponds to the positioning groove 6. The pressing plate 11 and the pen cartridge 2 can be relatively positioned.
[0036] Combining Figure 2 and Figure 3 As shown in the drawings, the side wall of the pen cartridge 2 is provided with a core taking through groove 7 which covers the position of one of the core holes 5. When the core taking through grooves 7 of all the pen cartridges 2 are aligned, all the core holes 5 are blocked by the adjacent pen cartridges 2, and the pen core 3 cannot be directly taken out. If the adjacent pen cartridges 2 are rotated to an angle, the core hole 5 of one of the pen cartridges 2 is aligned with the core taking through groove 7 of another pen cartridge 2, and then the pen core 3 in the core hole 5 can be taken out from the core taking through groove 7. Therefore, the pen core 3 can be more conveniently taken out without disassembling the pen cartridge 2 from the pen barrel.
[0037] The utility model has the advantages of:
[0038] The pen cartridge 2 can carry more pen cores 3 as replacement cores. The replacement cores can be more types of pens, such as wax crayons or colored pencils, as long as the same shape is adopted. The pen cartridge 2 can better meet the drawing needs and is suitable for occasions where it is inconvenient to carry a large number of objects. The pen cartridge 2 can be more conveniently taken out without disassembling the pen cartridge 2 from the pen barrel.
[0039] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.
[0040] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the utility model patent. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
