Technical Field
[0001] The utility model relates to the field of pencil sharpeners, in particular to a double-hole electric pencil sharpener capable of changing the diameter of the pencil. Background Art
[0002] Pencil sharpeners are very popular stationery because pencils are the stationery that most people like to use. Although automatic pencils are very convenient, their refills are of certain specifications after all. In some occasions, such as when thicker or thinner pencils are required, they are not suitable for use. In addition, the price of automatic pencils is much higher than that of ordinary pencils. Therefore, ordinary pencils that need to be sharpened are still used very frequently, and pencil sharpeners have become an indispensable tool.
[0003] However, the current pencil sharpeners all have a common problem, that is, a socket is provided on the housing of the pencil sharpener. When the pencil needs to be cut, the pencil is inserted into the pencil sharpener from the socket for cutting. Although the structure of such a pencil sharpener is simple, it can only cut pencil leads of fixed shape and thickness. Since the pencil leads used by art sketchers have different thicknesses, after cutting with the pencil sharpener, the sizes of pencil leads of different models will be the same. In particular, some large-sized pencils are very easy to break during use due to their relatively soft texture, which is inconvenient for users to use, and thus cannot meet the needs of such people, reducing the adaptability of the device.
[0004] Therefore, it is necessary to provide a double-hole electric pencil sharpener with variable diameter for sketching to solve the above-mentioned technical problems. Utility Model Content

[0031] A fourth transmission gear 4, the fourth transmission gear 4 is meshed with the other side of the driving gear 21, a fifth transmission gear 41 is meshed on one side of the fourth transmission gear 4, a sixth transmission gear 42 is meshed on one side of the fifth transmission gear 41, a second pencil sharpener assembly 47 is clamped on the top of the sixth transmission gear 42, an adjustment block 46 is provided on the inner side of the second pencil sharpener assembly 47, an adjustment rod 44 is provided at the bottom of the adjustment block 46, the adjustment rod 44 passes through the interior of the sixth transmission gear 42 and extends to the bottom, a third adjustment member 43 is provided at the bottom of the adjustment rod 44, a second spring 45 is provided on the top of the third adjustment member 43, and the second spring 45 is provided at the bottom of the sixth transmission gear 42.
[0032] The top of the first spring 36 is rotatably connected to the bottom of the third transmission gear 32 .
[0033] A bottom cover 11 is disposed at the bottom of the driving gear 21 , and the bottom cover 11 is disposed at the bottom of the housing 1 .
[0034] The third transmission gear 32 , the second transmission gear 31 , the first transmission gear 3 , the fourth transmission gear 4 , the fifth transmission gear 41 and the sixth transmission gear 42 are all disposed on the top of the bottom cover 11 .
[0035] A top cover 12 is disposed on the top of the housing 1 , and the tops of the first pencil sharpener assembly 35 and the second pencil sharpener assembly 47 are both disposed on the bottom of the top cover 12 .
[0036] A power interface 5 is provided on the front of the housing 1 , and the power interface 5 is connected to the driving motor 2 via a power line.
[0037] The second adjusting member 34 is provided with a limit structure on both sides, which cooperates with the structure of the inner side surface of the housing 1 when in use, so that the second adjusting member 34 can only move up and down. The inner side surface of the second adjusting member 34 is conical and cooperates with the bottom of the outer side surface of the first pencil sharpener assembly 35;
[0038] When using the pencil, the user rotates the third adjusting member 43 so that the top of the third adjusting member 43 supports the top of the adjusting rod 44, so that the adjusting rod 44 moves upward, and then the top of the adjusting rod 44 pushes up the bottom of the adjusting block 46, so as to adjust the thickness of the pencil.
[0039] The top of the third adjusting member 43 is provided with three convex surfaces of different heights, so that the top of the adjusting rod 44 can be adjusted to different heights.
[0040] The lead of a sketch pencil has a larger diameter as the B number increases. Therefore, the pencil sharpener is provided with a double hole and the first pencil sharpener assembly 35 for sharpening a wooden handle with a variable diameter is designed to meet the needs of the thickness of the lead. The diameter is increased to sharpen a thick lead type pen, and the diameter is reduced to sharpen a thin lead type pen. This increases the adaptability of the pencil sharpener. After the wooden handle is sharpened, the lead is inserted into the other hole, and the lead is sharpened by the second pencil sharpener assembly 47. The two are operated separately, which is more convenient for users to use.
[0041] The working principle of the double-hole electric pencil sharpener with variable diameter provided by the utility model is as follows:
[0042] When using the pencil, the user puts the pencil into the first pencil sharpener assembly 35, and then starts the driving motor 2, which drives the first transmission gear 3 to rotate through the driving gear 21, and then drives the first transmission gear 3 to rotate through the second transmission gear 31, and then drives the third transmission gear 32 to rotate, and then drives the first pencil sharpener assembly 35 to rotate, so as to cut the wood chips of the pencil;
[0043] When pencil leads of different thicknesses need to be used, the user can rotate the first adjusting member 33, and the inclined surface at the top of the first adjusting member 33 cooperates with the inclined surface at the bottom of the second adjusting member 34, so as to adjust the height of the second adjusting member 34. When the second adjusting member 34 moves downward, the activity space at the bottom of the first pencil sharpener assembly 35 becomes larger, and the first clamping member 351 and the second clamping member 352 can open the bottom around the top connection to cut the wooden handle of the pencil, so that pencil leads of different thicknesses can be used.
[0044] Then the user puts the pencil into the second pencil sharpener assembly 47, and makes one end of the pencil lead rest on the adjusting block 46. Then the user drives the motor 2 to drive the fourth transmission gear 4 through the driving gear 21, and then the fourth transmission 4 drives the sixth transmission gear 42 to rotate through the fifth transmission gear 41, and then the sixth transmission gear 42 drives the second pencil sharpener assembly 47 to rotate, and then the second pencil sharpener assembly 47 sharpens the pencil lead.
[0045] Compared with the related art, the double-hole variable diameter sketch electric pencil sharpener provided by the utility model has the following beneficial effects:
[0046] By matching the inclined surface at the top of the first adjusting member 33 with the inclined surface at the bottom of the second adjusting member 34, when the first adjusting member 33 is rotated, the second adjusting member 34 can be moved up and down, so that the opening distance of the bottom of the first pencil sharpener assembly 35 can be adjusted, thereby changing the caliber of the pencil to be cut, so as to meet the needs of cutting pencils with different types of thick and thin lead cores, thereby increasing the adaptability of the device.

The difference is that, in the double-hole electric pencil sharpener with adjustable diameter, a protective cover 6 is provided on the outer side surface of the shell 1.
[0049] The protective sleeve 6 is made of rubber material and has a certain elasticity.
[0050] The working principle of the double-hole electric pencil sharpener with variable diameter provided by the utility model is as follows:
[0051] When in use, the user can put the protective cover 6 on the outer side of the shell 1 to protect the shell 1.
[0052] Compared with the related art, the double-hole variable diameter sketch electric pencil sharpener provided by the utility model has the following beneficial effects:
