It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1-7, the preferred embodiment of the present application is:

the utility model provides a pencil sharpener frame, includes main part 1 and sets up first blade 2 and second blade 3 in main part 1, is equipped with on the main part 1 and supplies the 5 male pencil holes 11 of advancing of pencil, and first blade 2 and second blade 3 set up around advancing pencil holes 11 axial, and just first blade 2 sets up at the rear end, is suitable for the wood part of cutting 5, and second blade 3 sets up at the front end, is suitable for the pencil lead part of cutting 5.

As shown in fig. 2, in actual use, a user needs to insert the pen 5 into the pen hole 11 and rotate the pen to roll the pen.

And a brand-new pencil needs to be cut into a state that can be used for writing as shown in fig. 2, two steps of cutting external wood and internal lead are needed, but in the conventional technical scheme, the wood and the lead are cut by the same blade, but the wood is more worn by the blade relative to the lead, so that the wood is cut very easily to be blunt, and the pencil sharpener holder cannot smoothly complete pencil sharpening and has short service life.

Therefore, as an improvement, the inventor of the present application divides the blade into two parts, namely a first blade 2 and a second blade 3, the strength of the two parts is different, the strength of the first blade 2 is greater than that of the second blade 3, and the two parts are arranged along the axial direction of the pencil feeding hole 11 in a front-back manner, because in practical use, the pencil 5 automatically advances when the pencil is rolled up, once the wood part outside the pencil 5 is cut off, the pencil 5 advances after the pencil lead part is exposed, and the pencil lead part is sent to the second blade 3, so that the first blade 2 with high strength is only used for cutting the wood, the second blade 3 with lower strength is only used for cutting the pencil lead, division is realized, and the strength of the two blades is within a reasonable recognition range for completing respective cutting work, and is not easy to damage, and the service life is long.

It is worth mentioning that the present application divides the blade into two parts, rather than replacing the entire blade with a high strength blade, because if the entire blade is replaced with a high strength blade, the blade in the lead core cutting part does not need such a high strength material at all, thereby causing unnecessary waste of material and an increase in manufacturing cost.

Also, in order to ensure that the cut pen 5 can be in the same state as that shown in fig. 2, in the present embodiment, both the first blade 2 and the second blade 3 are obliquely arranged so as to be adapted to roll the front end of the pen 5 inserted into the holder of the pencil sharpener into a cone structure with a small front and a large rear. The above-described structure is common knowledge to a person skilled in the art as in conventional solutions, and therefore the specific structure of the inclined arrangement is not described in detail.

In addition, in the embodiment, the first blade 2 is installed on the front surface of the main body 1, the second blade 3 is installed on the back surface of the main body 1, the front surface is the surface shown in fig. 3, the back surface is the surface shown in fig. 5, and the first blade 2 and the second blade 3 are arranged on the front surface and the back surface, so that on one hand, the internal space of the main body 1 can be more reasonably utilized, the structure is more compact, on the other hand, the first blade 2 and the second blade 3 can form a clamping effect on the pen 5, and the stability of the pen sharpening work is improved.

Further, as shown in fig. 4 and 7, in the present embodiment, the first blade 2 and the second blade 3 are each fixed to the main body 1 by bolting. The structure is simple and stable, and the installation is convenient. Of course, other connection methods such as welding, bonding, etc. may be used.

However, the second blade 3 is used for cutting lead, which is relatively fragile and easily broken, and therefore, the second blade 3 is required to have higher stability. In the present embodiment, the main body 1 is provided with a mounting groove 12 where the second blade 3 is mounted, the second blade 3 is adapted to be inserted into the mounting groove 12, and the mounting groove 12 is adapted to the shape of the second blade 3. Above-mentioned structure can effectively guarantee to be difficult to after the embedding of second blade 3 left and right sides rotation and horizontal migration to guarantee second blade 3's stability.

As shown in fig. 6, in this embodiment, in order to further improve the stability of the second blade 3, a reinforcing block 13 is further disposed on the sidewall of the mounting groove 12, and a horizontal extension 131 is disposed on the reinforcing block 13, and the horizontal extension 131 is adapted to press the second blade 3.

In addition, in the embodiment, in order to ensure that the pen 5 can contact the first blade 2 and the second blade 3 after being inserted into the pen sharpener holder, the rear end inside the main body 1 is provided with the pen container 4, the pen container 4 is provided with the notch 41, and the blade part of the first blade 2 is suitable for being inserted into the notch 41 and contacting with the pen 5 inserted into the pen container 4, so that the pen container 4 can play a limiting role on the pen 5 inserted into the pen sharpener holder, the pen 5 advances according to the internal channel of the pen container 4, the side edge of the pen container 4 starts to form the notch 41, and the blade part of the first blade 2 is inserted into the notch 41, so that the normal cutting work of the first blade 2 can be effectively ensured.

And the blade part of the second blade 3 is arranged at the outlet of the pen holding container 4 and is suitable for contacting with the pens 5 which penetrate out of the pen holding container 4, so that the pens can contact with the second blade 3 after passing through the pen holding container 4 after cutting wood by the first blade 2, and then the lead is cut.

Further, in the embodiment, the pen container 4 is in a cone structure with a small front part and a large rear part, and the inclination degree of the outer surface of the cone structure is matched with the inclination degree of the first blade 2 and the second blade 3. In actual use, the inclination degree of the outer surface of the cone structure is generally the same as the inclination degree of the first blade 2 and the second blade 3, and in the embodiment, only one of the two blades is arranged on the front side and inclined towards the back side, and the other blade is arranged on the back side and inclined towards the front side, so that the normal work of the first blade 2 and the second blade 3 is ensured, and the cut pen 5 can write normally.

It should be noted that the specific inclination angles and the specific positions of the first blade 2 and the second blade 3 are similar to those of the conventional technical solutions, and only after the pen 5 is inserted into the pen sharpener holder, the first blade 2 and the second blade 3 can both contact with the pen 5 and perform normal cutting operation.

In addition, in the present embodiment, the first blade 2 and the second blade 3 are both made of steel, because steel has advantages of high strength and good workability. Of course, other materials may be used.

Further, the first blade 2 can be made of high carbon steel or tungsten steel, and has the advantages of high hardness, wear resistance and high strength, so that the first blade 2 can cut wood for a long time without excessive wear after the first blade is made of the materials. Of course, other high hardness and high strength steels may be used for the first blade 2.

Since the lead core is made of a soft material, there is no excessive requirement for the second blade 3, and therefore, the second blade 3 may be made of a general steel material.

It is worth mentioning that the pencil sharpener rack can be used as a knife rack structure in a common pencil sharpener, and can also be independently manufactured into a simple pencil sharpener for sharpening pencils.

The foregoing has described the general principles, essential features, and advantages of the application.
