[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0030] Example 1
[0031] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a hamster pencil sharpener with a ratchet, the hamster pencil sharpener with a ratchet comprises a main shell 1, a garbage compartment 2 is arranged on the inner side of the main shell 1, a cutting assembly 3 is arranged on the inner side of the garbage compartment 2, a bionic component 4 is arranged on the outer side of the cutting assembly 3, the cutting assembly 3 comprises a first cutting component 31 and a second cutting component 32, the first cutting component 31 comprises a large-hole ratchet 311, the outer side of the large-hole ratchet 311 is provided with ratchet upper teeth 312 arranged equidistantly, and the ratchet upper teeth 312 are distributed in a ring array around the large-hole ratchet 311, one side of the large-hole ratchet 311 is also arranged with a clamping claw, a ratchet convex shaft 313 is fixedly installed on the side of the large-hole ratchet 311 away from the clamping claw, and the large-hole The ratchet 311 and the ratchet cam 313 are an integrally formed structure. The first cutting member 31 also includes a large-hole fixing seat 314. Elastic foot guards 315 are distributed on both sides of the large-hole fixing seat 314. The large-hole fixing seat 314 engages or disengages with the large-hole ratchet 311 through the elastic foot guards 315. One side of the teeth 312 on a single ratchet is steeper and the other side is gentler. When rotating in the positive direction, the gentle side can easily slide on the elastic foot guard 315 and cannot transmit power, so that the pencil can complete the cutting. When the large-hole ratchet 311 rotates in the reverse direction, the steep side will firmly bite the elastic foot guard 315, driving the pencil in the clamp in the large-hole ratchet 311 to rotate synchronously with it, and producing a "cl icclic" sound in the process, which is more technological, making consumers feel both labor-saving and comfortable when using it.
[0032] A large-hole knife core 316 is provided on the side of the large-hole ratchet 311 away from the large-hole fixing seat 314. The large-hole knife core 316 is formed into a whole with the large-hole ratchet 311 through an ultrasonic welding process. The large-hole knife core 316 always keeps synchronous rotation with the large-hole ratchet 311, so that when the pencil reaches the maximum moving distance in the forward rotation, the large-hole knife core 316 rotates synchronously with the large-hole ratchet 311 when the pencil is reversed, so there is no need to release the hand.
[0033] The large hole knife core 316 is installed with a blade 317 by means of a screw, and the ratchet cam 313 is distributed on the outside of the large hole knife core 316. When the pencil rotates, the blade 317 can cut the pencil through the contact between the blade 317 and the pencil. The ratchet cam 313 rotates on the outside of the large hole knife core 316 and in the garbage compartment 2 to remove the pencil waste around the large hole knife core 316 and reduce blockage.
[0034] The second cutting member 32 includes a large-hole sheath 321 and a small-hole sheath 322. The diameter of the small-hole sheath 322 is smaller than that of the large-hole sheath 321 and the materials are the same. The large-hole sheath 321 and the small-hole sheath 322 are respectively installed at the two ends of the main shell 1 through the clamps 323. The clamps 323 are distributed at both ends of the main shell 1 to facilitate consumers to use it with both hands. The large-hole sheath 321 and the small-hole sheath 322 can make the pencil inserted into the pencil hole stable and accurately positioned through their own shrinkage, and the pencil is very unlikely to break when cutting.
[0035] The second cutting piece 32 also includes a small hole fixing seat 324 and a small hole ratchet 325. The small hole fixing seat 324 is arranged at one end of the main shell body 1 away from the large hole fixing seat 314. An elastic foot guard 315 is also arranged on the outer side of the small hole fixing seat 324. The small hole fixing seat 324 engages or disengages with the small hole ratchet 325 correspondingly through the elastic foot guard 315. The small hole fixing seat 324 and the small hole ratchet 325 have the same operating principle and composition structure as the large hole fixing seat 314 and the large hole ratchet 311 respectively, and the difference lies in the installation position and model.
[0036] The bionic part 4 includes a front cover 41, which is installed on the outside of the garbage compartment 2 and connected to the main shell 1. A chip ejection port 42 is provided on the side of the main shell 1 away from the front cover 41. The chip ejection port 42 is communicated with the inside of the garbage compartment 2. A garbage cover 43 is installed on the inner side of the chip ejection port 42. The front cover 41 is a transparent structure for easy observation of the cutting status. The garbage compartment 2 can collect the cut pencil waste and discharge it from the chip ejection port 42 through the garbage cover 43 to ensure the cleanliness of the device.
[0037] The main shell 1 and the front cover 41 adopt a hamster bionic design. After the main shell 1 and the front cover 41 are spliced together, different colors are used for the front and back hollows to make the product lively and bony, which can make consumers happy physically and mentally.
[0038] When in use, first install the large-hole ratchet 311 and the large-hole knife core 316 and the small-hole ratchet 325 and the small-hole knife core 326 which are ultrasonically welded together on the inner side of the garbage compartment 2, and then assemble the large-hole ratchet 311 and the corresponding large-hole fixing seat 314 and the small-hole ratchet 325 and the corresponding small-hole fixing seat 324 on the clamps 323 at both ends of the main shell 1 respectively. Since the small-hole fixing seat 324 and the small-hole ratchet 325 have the same operating principles and composition structures as the large-hole fixing seat 314 and the large-hole ratchet 311 respectively, the difference lies in the installation position and model, which will not be elaborated one by one. Taking the large-hole ratchet 311 as an example, when a pencil is inserted into the clamp 323 and rotated, since one side of the teeth 312 on the single ratchet is steeper and the other side is gentler, when rotating in the positive direction, the gentle side is easy to The large hole ratchet 311 rotates in the opposite direction, and the steep side will firmly bite the elastic foot 315, driving the large hole ratchet 311 and the connected large hole knife core 316 to rotate synchronously, so that the relative position of the blade 317 on the large hole knife core 316 for cutting the pencil does not change, and the ratchet convex shaft 313 rotates on the outside of the large hole knife core 316 to remove the pencil waste outside the large hole knife core 316 and in the garbage compartment 2. Similarly, the small hole fixing seat 324 and the small hole ratchet 325 cooperate as above, so that the pencil sharpener can be used to cut the pencil without loosening the hands, and the pencil can be rotated continuously, which is very labor-saving. At the same time, the "cliccl The sound of "ic" has a more technological sense, making consumers feel both labor-saving and comfortable when using it, and the large-hole sheath 321 and the small-hole sheath 322 respectively installed in the clamps 323 at both ends of the main shell 1 can adapt to pencils of different shapes through their own shrinkage, with accurate positioning and less lead breakage, and can also be convenient for consumers to use with both hands, and the cute and attractive hamster bionic design that conforms to ergonomics after the main shell 1 and the front cover 41 are assembled, and the different colors of the front and back hollows make the product lively and full of bone feeling, which makes consumers happy physically and mentally, and can also effectively collect pencil waste generated during the cutting process to ensure the cleanliness of the device.
[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
