Abstract
The utility model relates to an electric pencil sharpener which comprises a miniature motor, a transmission device and a pencil sharpener device. The electric pencil sharpener is electrically connected with a USB plug; after being electrically connected with a USB socket, the USB plug supplies power for the miniature motor, so as to drive the transmission device and the pencil sharpener to rotate. When in use, the electric pencil sharpener is economic, convenient and environment-friendly.
Description
Technical field
The utility model relates to a kind of pencil sharpener, particularly can be from the electronic pencil sharpener of the USB interface power taking of computer.
Background technology
Along with the development of digital product, nearly all equipment can use USB interface, and it is fast that reason is that USB interface transmits data, the more important thing is can support hot plug and can not burn out equipment.Existing electronic pencil sharpener need be plugged the work to take power of common power ability, can not use with " suiting measures to local conditions ".Under the background of the utility model just because of digital product extensive use USB interface, power taking for convenience and propose the invention.
The utility model content
The purpose of this utility model is in order to overcome the deficiency that above-mentioned technology exists, a kind of electronic pencil sharpener that makes things convenient for power taking to be provided.
In order to achieve the above object, the utility model mainly adopts this technical scheme:
A kind of electronic pencil sharpener, comprise the electronic pencil sharpener body that constitutes by micromachine, transmission device and penknife device, electronic pencil sharpener body is electrically connected with USB plug, and to power to micromachine, drive transmission and penknife turn round behind the USB plug electrical connection USB socket.
The DC socket of pencil sharpener is electrically connected with the USB line, and an end of described USB line is a DC plug, and the other end is the USB plug that can be electrically connected with USB socket.
Compared with prior art, the utility model can directly be electrically connected with the USB socket of digital equipment by USB plug and obtain power supply, thereby drives electronic pencil sharpener work.More economical, convenient, environmental protection in the use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with most preferred embodiment and accompanying drawing, the utility model is described in further detail.
Electronic pencil sharpener body 1 is made up of micromachine 6, transmission device 7 and penknife device 8.Micromachine 6 is connected common power, micromachine 6 drive transmissions 7, thus the penknife of transmission penknife device 8 rotates, and pencil is peeled.
In order to obtain power supply from digital product more easily, on the basis of original electronic pencil sharpener body 1, connect a general USB line 2, as shown in Figure 1.USB line 2 one ends are USB plugs 5, and the other end is a DC plug 4.Concrete practical technique scheme is: the DC socket 3 of electronic pencil sharpener body 1 connects the DC plug 4 of USB line 2, the USB plug 5 of USB line 2 connects the USB socket of computer, under the situation of computer operate as normal, the micromachine 6 of electronic pencil sharpener body 1 is obtained power work.
Electronic pencil sharpener only needs a very cheap USB line, the problem of just can save the action of packed battery, frequently changing battery and need not consider the battery pollution aspect, perhaps need not bulky expensive again external transformer, can reduce this machine cost and use cost greatly.
Claims (2)
1. electronic pencil sharpener, comprise the electronic pencil sharpener body that constitutes by micromachine, transmission device and penknife device, it is characterized in that: electronic pencil sharpener body is electrically connected with USB plug, to power to micromachine, drive transmission and penknife turn round behind the USB plug electrical connection USB socket.
2. electronic pencil sharpener according to claim 1 is characterized in that, the DC socket of pencil sharpener is electrically connected with the USB line, and an end of described USB line is a DC plug, and the other end is the USB plug that can be electrically connected with USB socket.
