Since pencils have different thicknesses, the pencil sharpener feed module needs to be optimized and designed to adapt to pencils of different thicknesses. There are currently two main solutions. One is to make the pen feed wheel softer, so as to use the deformation of the pen feed wheel to adapt to pencils of different thicknesses; the second is to install the pen feed wheel axially slidably on the clamping shaft, and then set a spring on the clamping shaft, and use the truncated cone body to slide the pen feed wheel to adapt to pencils of different thicknesses, such as the technical solution recorded in the Chinese utility model patent with publication number CN211764569U.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0039] See also Figure 1-Figure 2 The pencil sharpener feed module of this embodiment includes a jacket 130 , a bottom shell 110 , and an upper cover 120 . The jacket 130 is sleeved outside the bottom shell 110 , and the upper cover 120 is installed on the bottom shell 110 .

[0040] Specifically, see Figure 1-Figure 13 The bottom shell 110 is provided with a snap groove 111, a lower anti-rotation groove 112, and a lower anti-rotation protrusion 113, and the upper cover 120 is provided with a snap piece 121, an upper anti-rotation protrusion 122, and an upper anti-rotation groove 123. A snap platform 1111 is provided inside the snap groove 111, and a snap protrusion 1211 is provided on the snap piece 121, and the snap piece 121 is elastic.

[0041] The snap-on piece 121 is inserted into the snap-on groove 111, and the snap-on protrusion 1211 passes through the snap-on platform 1111 and is clamped with the snap-on platform 1111 to realize the assembly of the upper cover 120 and the lower shell 110, and the lower anti-rotation protrusion 113 is inserted into the upper anti-rotation groove 123, and the upper anti-rotation protrusion 122 is inserted into the lower anti-rotation groove 112, so that the upper cover 120 and the lower shell 110 cannot rotate.

[0042] Preferably, the bottom shell 110 is further provided with a plug hole 115, and the plug hole 115 is plugged and assembled with the plug post 124, and the plug post 124 is installed on the upper cover 120. This design is mainly to ensure the positioning and assembly between the upper cover 120 and the lower shell 110.

[0043] See also Figure 1-Figure 15 The lower shell 110 is provided with a spring slot 101, a slider seat 114, an offset seat 150, and an axle seat 140. The slider seat 114 has a through-slider slot 1141 inside, and the slider slot 1141 is connected to the corresponding spring slot 101;

[0044] The offset seat 150 is provided with an offset groove 151, and the shaft seat 140 is provided with a shaft groove 141. The shaft groove 141 is assembled with one end of the corresponding clamping shaft 310. The other end of the clamping shaft 310 is inserted into the corresponding offset groove 151 and is pressed by one end of the slider 220. The other end of the slider 220 is assembled or pressed with one end of the elastic member 210. The other end of the elastic member 210 is pressed against the inner side of the outer sleeve 130. The slider 220 is engaged and slidably installed in the slider groove 1141. The elastic member 210 applies an elastic force to the slider 220 to press the clamping shaft 310. There are three offset seats 150 and three shaft seats 140, respectively, and they correspond to three clamping shafts 310 respectively.

[0045] A deflection portion 142 is provided on the shaft groove 141 , and the deflection portion 142 is used to provide a clearance space when the corresponding clamping shaft 310 is located at one end of the offset groove 151 and deflects, thereby ensuring that the clamping shaft 310 can be effectively deflected.

[0046] The pen-feeding wheel 410, the worm wheel 420, and the shaft sleeve 320 are respectively mounted or arranged on the clamping shaft 310. The pen-feeding wheel 410 and the worm wheel 420 cannot rotate in a circular manner relative to the clamping shaft 310, and the shaft sleeve 320 cannot move axially relative to the clamping shaft 310, thereby limiting the positions of the pen-feeding wheel 410 and the worm wheel 420 in the axial direction of the clamping shaft 310. At the same time, it also prevents the pen-feeding wheel 410 from moving toward the corresponding offset groove 151, which affects the cooperation between the slider 220 and the clamping shaft 310.

[0047] The pen feeding wheel 410 is made of elastic material, such as rubber or silicone, and this arrangement is mainly to ensure that the three pen feeding wheels 410 are respectively pressed against the side walls of the pencil during use, thereby maintaining effective clamping and conveying. The outer wall of the pen feeding wheel 410 is provided with a concave-convex surface 411, which is mainly to increase friction and ensure that the pencil can be effectively conveyed when the pen feeding wheel 410 rotates.

[0048] The worm wheel 420 is meshed with the worm part 431 for transmission. The worm part 431 is arranged on the transmission member 430. The transmission member 430 is also provided with a gear part 432. The three gear parts 432 are respectively meshed with the transmission teeth 440 for transmission. The transmission teeth 440 are rotatably mounted on the bottom shell 110. The upper cover 120 is provided with an upper cover shaft hole 103. The bottom shell 110 is provided with a bottom shell shaft hole 102. The two ends of the transmission member 430 are respectively installed in the corresponding upper cover shaft hole 103 and the bottom shell shaft hole 102 and can be assembled rotatably. When in use, only one of the transmission members 430 needs to be driven to rotate or the transmission teeth 440 needs to be driven to rotate to make the three transmission members 430 rotate synchronously, so that the three pen feeding wheels 410 rotate synchronously to stably transport pencils. After the pencil is sharpened, the pencil can be directly pulled out, because the pencil feed wheel 410 is elastic and the three pencil feed wheels can swing relative to the pencil, so the pencil is not fixed or stuck, but has a certain friction force, so as long as the force of pulling out the pencil is greater than the friction force, the pencil can be pulled out. The specific use process can refer to the Chinese utility model patent with publication number CN211764569U.

[0049] See also Figure 4-Figure 15 In some embodiments, an upper pressure seat 125 is further provided on the upper cover 120, and the upper pressure seat 125 is pressed or fitted on the corresponding clamping shaft 310 to keep the clamping shaft 310 from being displaced in the direction of the upper cover 120 and the bottom shell 110 (axial direction of the socket 115).

[0050] In some embodiments, the offset seat 150 and the corresponding shaft seat 140 and slider seat 114 are integrally formed, so that the entire bottom shell 110 is integrally formed to facilitate manufacturing and reduce manufacturing costs.

[0051] The elastic member of this embodiment is a spring, but is certainly not limited to a spring. Theoretically, any component that can provide elastic damping to the slider will do, such as an elastic airbag, a spring sheet, a magnet (magnets of the same polarity that repel each other are installed on the bottom shell and the slider respectively), an elastic rod (a rod-shaped object with elasticity), etc.

[0052] The operation process of this embodiment is roughly as follows:

[0053] S1. First, insert a pencil between the three pen-feeding wheels 410.

[0054] S2. The outer wall of the pencil is pressed against the three pen-feeding wheels 410, thereby squeezing the pen-feeding wheels 410, and the pen-feeding wheels 410 are squeezed and swing outward, but the end of the clamping shaft 310 assembled with the shaft groove 141 can only deflect at a small angle in the shaft groove 141 and the deflection part 142 due to the limitation of the shaft groove 141, and the clamping shaft 310 is assembled with the offset groove 151. One end squeezes the slider 220, and the slider 220 squeezes the elastic member 210 and slides into the slider groove 1141, and at this time, a structure similar to a lever is formed, with the fulcrum at the assembly point of the clamping shaft 310 and the shaft groove 141, and the clamping point at the pen-feeding wheel 410, so that the pencil can be effectively kept clamped by the pen-feeding wheel 410. At the same time, since the angle of the assembly of the clamping shaft 310 and the shaft groove 141 is relatively small and the worm wheel and worm part are installed at one end close to the shaft groove 141, the worm wheel and worm part can still be kept in meshing state when the clamping shaft 310 swings, because the swing angle of the worm wheel is small. In this way, the pencil feeding wheel can be effectively driven to rotate while clamping the pencil, thereby ensuring the effective transportation of the pencil. At the same time, the design of the three pencil feeding wheels swinging on the corresponding clamping shaft 310 can effectively increase the range of pencil diameters that can be adapted, and can also ensure effective clamping without getting stuck, so as to avoid excessive effort or inability to pull out the pencil later. Embodiment 2

[0055] See also Figure 16-Figure 22 The difference between this embodiment and the first embodiment is that there is no outer cover 130, the elastic member 210 is an elastic wire instead of a spring, and the slider seat 114 is improved. The details are as follows:

[0056] The slider seat 114 is also provided with a through slot 1142, which passes through the side wall of the slider seat 114 and is connected to the slider groove 1141; the slider 220 is provided with a slider hole 221, the elastic member 210 includes a first end 211, a bent portion 212, and a second end 213, the first end 211 is pressed against the inner side of the bottom shell 110, the second end 213 passes through the through slot 1142 and is inserted into the slider hole 221 and assembled and fixed with the slider 220, the bent portion 212 is installed on the support shaft 160, the support shaft 160 is installed on the bottom shell 110 and a support platform 161 is provided on the support shaft 160, and the support platform supports the elastic member 210. The elastic member 210 is elastic, and when in use, the elastic member 210 applies an elastic force to the slider 220 to press against the clamping shaft 310, and the through slot 1142 provides a clearance space for the deformation and swing of the second end 213.

[0057] The upper cover 120 is provided with a pressing platform 126 , and the end surface of the pressing platform 126 is fitted or pressed against the elastic member 210 so as not to be displaced in the direction from the upper cover 120 to the bottom shell 110 (the axial direction of the insertion hole 115 ).

[0058] The usage of this embodiment is the same as that of the first embodiment, in that the elastic member 210 provides elastic support to the slider, and the pen feed wheel 410 can flexibly adapt to pencils of various diameters under the swing of the clamping shaft 310 . Embodiment 3

[0059] See also Figure 23-Figure 31 The difference between this embodiment and the first embodiment is that the elastic member 210 becomes an elastic ring, as follows:

[0060] An annular groove 116 is provided on the bottom shell 110, and the annular groove 116 is connected to the spring groove 101, and the spring groove 101 is connected to the slider groove 1141. An annular elastic member 210 is installed in the annular groove 116. The elastic member 210 is elastic and has a bent end 211 on one end. The bent end 211 passes through the spring groove 101 and enters the bottom shell 110 to achieve assembly with the bottom shell 110.

[0061] The two ends of the slider 220 are respectively in close contact with the elastic member 210 and the corresponding clamping shaft 310, thereby providing damping for the swing of the clamping shaft 310. When the clamping shaft 310 swings, it squeezes the elastic member 210, so that the elastic member 210 undergoes elastic deformation and provides elastic damping.

[0062] The usage of this embodiment is the same as that of the first embodiment, that is, the slider applies swing damping to the clamping shaft 310 to achieve the clamping of the pen-feeding wheel and the pencil and the rotation of the pen-feeding wheel to transport the pencil.
