Embodiment 1

[0040] Example 1, see Figure 1-Figure 12 .

[0041] This embodiment provides a hand-held electric pencil sharpener, such as figure 1 As shown, this handheld electric pencil sharpener includes a housing 101 , a pencil holder 102 , a transmission mechanism 103 and a motor 104 . The casing 101 is in the shape of a strip, and the pencil holder 102 is arranged at the end of the casing 101 , and the pencil holder 102 can rotate relative to the casing 101 .

[0042] Such as figure 1 with figure 2 As shown, the housing 101 is in the shape of a strip, one end of the housing 101 is provided with an opening 105, the pencil chuck 102 is arranged at the opening 105, and the opening 105 is provided with a chuck cover 106, and the chuck cover 106 and the housing 101 are detachable connect. The casing 101 includes a bottom cover 107 , an upper cover 108 and a battery cover 109 . A motor compartment 110 and a transmission compartment 111 are formed between the bottom cover 107 and the ...

Embodiment 2

[0060] Example 2, see Figure 13 .

[0061] This embodiment provides a hand-held electric pencil sharpener. The only difference between this embodiment and Embodiment 1 is the transmission mechanism 103 . Please refer to the description of Embodiment 1 for structures not mentioned in this embodiment.

[0062] like Figure 13 As shown, the transmission mechanism 103 includes a planetary gear set 115 and an inner ring gear 116 , and the use of the planetary gear and the inner ring gear 116 as the transmission mechanism 103 can effectively reduce noise. The inner ring gear 116 is fixedly connected with the housing 101 , and the inner wall of the inner ring gear 116 has a plurality of inner teeth distributed along its circumference. The planetary gear set 115 includes a first sun gear 117 , a first planet carrier 118 and two first planet gears 119 .

[0063]The first sun gear 117 is fixedly connected to the first planet carrier 118, the first planet carrier 118 has two first pl...

Abstract

The invention relates to the field of stationery, and provides a handheld electric pencil sharpener. The handheld electric pencil sharpener comprises a shell, a pencil clamping head, a transmission mechanism, a motor gear and a motor, wherein the transmission mechanism, the motor gear and the motor are arranged in the shell; a fixing hole for clamping an end of a pencil is formed in the pencil clamping head; the pencil clamping head is rotatably arranged on the shell; the motor gear is connected with a rotating shaft of the motor; the transmission mechanism is provided with a power output part and a power input part; the power input part is connected with the motor gear; and the power output part is connected with the pencil clamping head. Structural characteristics of the traditional electric pencil sharpener are overthrown, and the pencil sharpener which is designed by reverse thinking does not have a knife rest or a garbage box, and is simple in structure and small in size. The pencil clamping head is used for fixing the tail of the pencil, the motor and the transmission mechanism drive the pencil to rotate, and the head of the pencil extends into the knife rest so that cutting of the pencil can be realized easily. The handheld electric pencil sharpener does not comprise the knife rest, so that the machining cost is reduced; and the pencil sharpener can be used with an existing knife rest.

Description

technical field [0001] The invention relates to the field of stationery, in particular to a hand-held electric pencil sharpener. Background technique [0002] Existing electric pencil sharpener is generally made up of parts such as housing, bottom cover, garbage cover, gear box, battery box, battery cover, knife rest and blade, and gear box is provided with motor, and the battery in the battery box is motor For power supply, the output shaft of the gear box is connected with the knife rest, and the knife rest is provided with blades. The tool holder is driven to rotate by the motor to perform the pencil sharpening process. The position corresponding to the tool holder on the face shell is provided with a pencil extension port, through which the end of the pencil to be sharpened can be extended into the tool holder. [0003] Due to the complex structure inside the housing of the existing electric pencil sharpener, the gear box, battery box, battery cover, knife rest and bla...
