EMBODIMENT
[0037] Please refer to Figures 1-6 A double-hole electric pencil sharpener, comprising: a double-hole electric pencil sharpener main body 1;
[0038] The holding structure 2 is arranged on one side of the double-hole electric pencil sharpener body 1 for hand holding, and is composed of an upper member 201 and a lower member 202, and the upper member 201 and the lower member 202 are connected through an adjusting structure.
[0039] The anti-skid sleeve 3 is wrapped outside the holding structure 2 for protection.
[0040] The double-hole electric pencil sharpener of the present application is mainly composed of a double-hole electric pencil sharpener body 1, a holding structure 2, an upper member 201, a lower member 202, and an anti-skid sleeve 3, and the following is the detailed structure and working principle.
[0041] I. The installation of the double-hole electric pencil sharpener body 1 as a whole:
[0042] Firstly, place the double-hole electric pencil sharpener body 1 on a suitable workbench, and ensure that the stable bottom 6 at the bottom thereof is in good contact with the workbench surface. The sleeve frame 601 connected to the inner periphery of the stable bottom 6 is sleeved outside the double-hole electric pencil sharpener body 1, which can increase the stability of the body and prevent it from moving easily due to vibration caused by the operation of the electric components during use.
[0043] Fix one end of the assembly plate 5 to the connecting piece 4. Then, align the one end of the assembly plate 5 with the connecting piece 4 with the side recess 101 on the side of the double-hole electric pencil sharpener body 1, so that the side recess 101 is clamped therein. Then, use several fastening bolts 501 to lock the assembly plate 5 and the double-hole electric pencil sharpener body 1, to ensure that the connecting piece 4 is stably installed on one side of the double-hole electric pencil sharpener body 1.
[0044] The holding structure 2 is composed of an upper member 201 and a lower member 202. First, install the adjusting rotating rod 2021 on the top of the lower member 202, to ensure that the adjusting rotating rod 2021 can rotate smoothly. Then, align the groove at the bottom of the upper member 201 with the adjusting rotating rod 2021, and connect the upper member 201 and the lower member 202 by means of threaded rotation connection. At this time, the first protruding ring 2023 between the upper member 201 and the lower member 202 is clamped in the groove at the bottom of the upper member 201, and the other end is in a state of mutual extrusion with the top of the lower member 202, which can increase the stability of the connection between the upper member 201 and the lower member 202.
[0045] Then, install the outer sleeve 401 on the outer periphery of the end of the upper member 201 facing the connecting piece 4, and then threadedly rotate the other end of the outer sleeve 401 to the inner part of the connecting piece 4, until the open end of the outer sleeve 401 abuts against the assembly plate 5, to complete the connection and installation of the holding structure 2 and the double-hole electric pencil sharpener body 1. Meanwhile, the second protruding ring 403 is glued to the side of the outer sleeve 401 in contact with the connecting piece 4, which can further improve the stability of the connection.
[0046] Finally, the protruding rods 2022 are evenly installed around the bottom of the lower component 202. The protruding design can provide support points for the hands when holding, preventing slipping.
[0047] The anti-slip sleeve 3 is composed of a supporting inner cylinder 301 and anti-slip protrusions 302. The supporting inner cylinder 301 is movably sleeved on the outside of the upper component 201 and the lower component 202 that have been assembled, ensuring that the supporting inner cylinder 301 can smoothly move on the holding structure 2. Then, the anti-slip protrusions 302 are evenly glued to the outer surface of the supporting inner cylinder 301. The anti-slip protrusions 302 are made of rubber material, which can enhance the holding feeling and reduce the possibility of the double-hole electric pencil sharpener body 1 slipping from the hand during use.
[0048] II. Working principle
[0049] The holding structure 2 is composed of the upper component 201 and the lower component 202, which are connected through the adjusting structure. The key component in the adjusting structure is the adjusting rotating rod 2021 installed at the top of the lower component 202, which is connected with the groove at the bottom of the upper component 201 through threaded rotation. When the user rotates the lower component 202, the adjusting rotating rod 2021 will drive the lower component 202 to move along the axial direction of the upper component 201 under the action of the thread. For example, rotating the lower component 202 clockwise will make the lower component 202 approach the upper component 201, and the overall length of the holding structure 2 will be shortened; rotating the lower component 202 counterclockwise will make the lower component 202 move away from the upper component 201, and the overall length of the holding structure 2 will be lengthened. This adjustability allows the user to flexibly adjust the length of the holding structure 2 according to their own hand size and use habits, and find the most comfortable and stable holding posture.
[0050] A first protruding ring 2023 is arranged between the upper component 201 and the lower component 202. One end of the first protruding ring 2023 is clamped in the groove at the bottom of the upper component 201, and the other end is pressed against the top of the lower component 202. During the adjusting process, the first protruding ring 2023 plays a role in limiting and increasing friction. When the user adjusts the length of the holding structure 2, the first protruding ring 2023 can prevent the upper component 201 and the lower component 202 from being excessively loose or shaking, ensuring the stability of the holding structure 2 at different lengths, and also buffering the impact force caused by adjusting to a certain extent, protecting the connection parts of the holding structure 2.
[0051] The protruding rods 2022 around the bottom of the lower member 202 will contact the hand when the user holds it, providing multiple support points for the hand. When the electric pencil sharpener is working and producing vibrations, the hand can better fit the holding structure 2, and the protruding rods 2022 can disperse the vibration force received by the hand, reducing the sliding of the hand caused by vibration, thereby enhancing the stability of holding. For example, during the pencil sharpening process, even if the electric components are running at high speed and producing vibrations, the hand can maintain a relatively stable holding state through contact with the protruding rods 2022, and will not easily change the holding position or force due to vibration, thereby ensuring the accuracy of pencil sharpening and the continuity of operation.
[0052] Mechanism of the anti-slip sleeve 3
[0053] The anti-slip sleeve 3 is composed of a supporting inner cylinder 301 and anti-slip protrusions 302. The supporting inner cylinder 301 is usually made of hard materials such as plastic, etc., which provides basic shape and structural support for the entire anti-slip sleeve 3, ensuring that the anti-slip sleeve 3 can be tightly fitted on the holding structure 2 and will not easily deform or be damaged during use.
[0054] The anti-slip protrusions 302 are evenly glued to the outer surface of the supporting inner cylinder 301, usually made of rubber material. Rubber has good elasticity and friction, and its texture and softness can better fit the skin of the hand, increasing the friction between the hand and the holding structure 2. When the user holds the holding structure 2 with the anti-slip sleeve 3, the hand contacts the anti-slip protrusions 302. Because the rubber material of the anti-slip protrusions 302 has a certain elasticity, it can deform slightly according to the pressure and shape of the hand, thereby increasing the contact area with the hand and further improving the friction. When the electric pencil sharpener is working, even if the internal electric components produce vibrations, the hand will not easily slide due to the greater friction between the hand and the anti-slip protrusions 302. For example, assuming that the electric pencil sharpener produces vibrations of a certain frequency and amplitude during the pencil sharpening process, the ordinary holding structure 2 may cause the hand to gradually slide under the action of vibration, affecting the stability of holding and the accuracy of pencil sharpening. The anti-slip sleeve 3 with anti-slip protrusions 302 can effectively "fix" the hand on the holding structure 2, allowing the hand to better resist the effects of vibration, ensuring that the user can maintain a stable holding posture throughout the pencil sharpening process, improving the quality and efficiency of pencil sharpening.
[0055] Connection and stability of the overall structure
[0056] The holding structure 2 is connected with the double-hole electric pencil sharpener body 1 through a fixing structure. The fixing structure comprises a connecting piece 4 arranged on one side of the double-hole electric pencil sharpener body 1, and a connecting screw rod 402 is arranged on one end of the connecting piece 4, and the other end of the connecting screw rod 402 is threadedly connected to the inside of the connecting piece 4. This threaded connection can realize relatively tight connection, and the user can adjust the tightness of the connection between the holding structure 2 and the double-hole electric pencil sharpener body 1 by rotating the connecting screw rod 402.
[0057] The outer sleeve 401 is glued with a second protruding ring 403 on the side in contact with the connecting piece 4, and the second protruding ring 403 is usually made of rubber. During the connection process, the second protruding ring 403 plays a role in sealing and increasing friction. On the one hand, it can fill the small gap between the outer sleeve 401 and the connecting piece 4, preventing dust, debris, etc. from entering the connection part, affecting the stability and service life of the connection; on the other hand, the second protruding ring 403 made of rubber increases the friction between the outer sleeve 401 and the connecting piece 4, making the connection between the two more stable, and effectively preventing the holding structure 2 from loosening or shaking relative to the double-hole electric pencil sharpener body 1 when the electric pencil sharpener is working.
[0058] The connecting piece 4 is installed on the double-hole electric pencil sharpener body 1 through an assembly plate 5. A side edge of the double-hole electric pencil sharpener body 1 is provided with a side recess 101, one end of the assembly plate 5 is fixed on the connecting piece 4, and the other end can be inserted into the side recess 101, and the assembly plate 5 and the double-hole electric pencil sharpener body 1 are locked through a plurality of fastening bolts 501. This installation method enables the connecting piece 4 to be stably fixed on the double-hole electric pencil sharpener body 1, providing a reliable installation basis for the holding structure 2. When the electric pencil sharpener is working, even if the vibration generated by the internal electric components is transmitted to the body, due to the cooperation of the assembly plate 5 and the side recess 101 and the fastening effect of the fastening bolts 501, the connecting piece 4 can remain stable and will not easily displace or loosen, thereby ensuring that the connection between the holding structure 2 and the double-hole electric pencil sharpener body 1 is always stable, further improving the stability and reliability of the entire pencil sharpener, and also facilitating assembly or disassembly according to the use requirements.
[0059] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and drawings are only examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principle.
