Preferably, the door 4 is transparent or translucent to facilitate the user's observation of the dust collecting condition in the first chamber 101, the pencil sharpening condition, and the state of the pencil sharpener 400. It is further preferred that the hatch 4 is attached to the side of the housing 100 by a snap-in structure.
Preferably, the housing 100 further comprises a second chamber 102 for housing the motor 201, the first chamber 101 for mounting the pencil sharpener 400 and the second chamber 102 for housing the motor 201 being laterally juxtaposed, the first chamber 101 and the second chamber 102 being separated by a longitudinal partition 2.
And, a third chamber 103 for accommodating the gear assembly 202 is further arranged below the first chamber 101 and the second chamber 102, the third chamber 103 is separated from the first chamber 101 by a transverse partition plate 3, the transverse partition plate 3 is provided with a through hole T, and the pencil sharpener 400 is abutted with the output shaft 203 through the through hole T.
Because the pencil sharpener 400 is easily worn during use, this affects the use of the entire electric pencil sharpener. In the present embodiment, there is provided a pencil sharpener 400 mounting structure that is easy to replace. Through this mounting structure, the user can replace the pencil sharpener 400, thereby utilizing the original host machine to continue to use the electric pencil sharpener, thereby saving the cost and realizing the maximum utilization of resources.
As shown in fig. 2, 3, 7-9, the pencil sharpener mounting structure for easy replacement includes a pencil sharpener 400, a movable sleeve 600 and a supporting plate 700 having a pencil insertion hole 1. The output shaft of the drive assembly is located below the support plate 700. The pencil sharpener 400 is located between the support plate 700 and the drive assembly. Wherein the pencil sharpener 400 includes a blade holder 10 and a blade 9 mounted on the blade holder 10, the blade 9 being mounted on the blade holder 10 by a screw, and the blade 9 being located at a middle section of the blade holder 10.
The movable cover 600 may be movably installed under the support plate 700 up and down with respect to the support plate 700. The bottom end of the knife rest 10 of the pencil sharpener 400 is provided with a connector 11 so as to be detachably connected with a driving assembly; the pen inlet end 12 of the upper end of the tool rest 10 is sleeved with the movable sleeve 600.

As shown in fig. 2 and 8, an elastic member 800 is provided between the movable sleeve 600 and the support plate 700. When no external force is applied, the elastic member 800 is moderately compressed, thereby having a downward force on the movable housing 600, securing the pencil sharpener 400 between the movable housing 600 and the driving assembly. When the user moves the movable sleeve 600 toward the support plate 700 and further compresses the elastic member 800, the movable sleeve 600 is away from the pen end 12 of the holder 10, so that the pen end 12 of the holder 10 can be separated from the movable sleeve 600. The upper end of the blade holder 10 is now free and is not limited in position, so that the user can remove the pencil sharpener 400 from the housing 100 after the detachable connection of the blade holder 10 to the drive assembly is released.
In contrast, when the pencil sharpener 400 is mounted on the housing 100, the movable sleeve 600 is moved toward the supporting plate 700, the compression amount of the elastic member 800 is increased to store energy, and then the bottom end of the knife rest 10 is connected to the driving assembly. Then, the movable sleeve 600 is released, the compressed amount of the compressed elastic member 800 is reduced, and the movable sleeve 600 is driven to move downwards, so that the movable sleeve 600 is sleeved with the pen inlet end 12 of the cutter holder 10.
Preferably, the fixing sleeve 900 is mounted on the support plate 700, the fixing sleeve 900 extends downwards from the bottom of the support plate 700, and one end of the movable sleeve 600 extends into the fixing sleeve 900, so that the fixing sleeve and the movable sleeve can be movably connected.
Preferably, as shown in fig. 7, 8, and 9, the fixing sleeve 900 is assembled to the support plate 700 by a snap structure. The fastening structure comprises a fastening hook 8 positioned at the upper end of the fixing sleeve 900 and a fastening hole 7 positioned on the supporting plate 700, wherein the fastening hook 8 penetrates through the fastening hole 7 from bottom to top and is hooked on the upper surface of the supporting plate 700, so that the fixing sleeve 900 is connected with the supporting plate 700. Such an arrangement facilitates assembly between the pencil sharpener 400, the movable sleeve 600, the elastic member 800 and the fixed sleeve 900. In the assembling process, the pencil sharpener 400, the movable sleeve 600, the elastic member 800 and the fixed sleeve 900 are assembled together according to the connection relationship, and then the fixed sleeve 900 is buckled on the supporting plate 700.
Meanwhile, a limiting structure for limiting the limiting movement of the movable sleeve 600 is arranged between the fixed sleeve 900 and the movable sleeve 600. The lowest position of the movable sleeve 600 moving downwards can be controlled by the limiting structure so as to ensure that the movable sleeve 600 keeps reasonable acting force on the tool rest 10.
More specifically, the limiting structure includes a first retainer ring 901 at the lower end of the fixed sleeve 900 and a second retainer ring 601 at the middle of the movable sleeve 600, and the second retainer ring 601 is located inside the first retainer ring 901 to limit the movable sleeve 600 from being separated from the fixed sleeve 900.
In addition, during the moving process of the movable sleeve 600, the insertion part C at the upper end of the movable sleeve 600 always extends into the pen inlet channel 500, the outer surface of the peripheral side part of the movable sleeve 600, the inner surface of the peripheral side part of the fixed sleeve 900, the lower surface of the support plate 700 and the upper surface of the second retainer ring 601 of the movable sleeve 600 are enclosed together to form a accommodating chamber K with a variable height, the elastic member 800 is installed in the accommodating chamber K, and the two ends of the elastic member 800 are propped between the support plate 700 and the second retainer ring 601. Preferably, the elastic member 800 is a spring, and the spring is coaxially sleeved outside the movable sleeve 600.
Thus, the second retainer 601 of the movable sleeve 600 may move up and down within the first retainer 901 and the support plate 700 or restricted area, the distance of which is limited by the maximum compression of the elastic member 800. And, the elastic member 800 generates a downward force on the movable housing 600 through the second retainer ring 601.
As shown in fig. 8 and 9, the pencil end 12 of the holder 10 preferably comprises a planar end wall P, the middle of which is provided with an upwardly projecting connecting wall Y. Preferably, the connecting wall Y is a wall of the pen hole of the tool holder 10, and its outer contour is adapted to the inner cavity of the movable sleeve 600.
The lower end of the movable sleeve 600 is provided with a concave cavity into which the connecting wall Y is inserted, and the lower end of the movable sleeve 600 is tightly contacted with the planar end wall P under the action of the elastic member 800.
Further preferably, a bottom plate D is arranged at the bottom end of the knife rest 10, a shaft hole R is arranged in the center of the bottom plate D, and the output shaft 203 of the driving assembly extends out of the through hole of the transverse partition plate 3 and is spliced with the shaft hole, so that the detachable connection between the knife rest 10 of the pencil sharpener 400 and the driving assembly is realized.
