Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

In the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

Further, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The use of terms such as "upper," "above," "lower," "below," and the like in describing relative spatial positions herein is for the purpose of facilitating description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly

In the present invention, unless otherwise explicitly specified or limited, the terms "disposed," "sleeved," "connected," "penetrating," "plugged," and the like are to be construed broadly, e.g., as a fixed connection, a detachable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 and 3, the pencil thickness adjusting mechanism of an electric pencil sharpener of the present invention comprises a main machine 1, a cutter holder 4, a battery 10, a pencil feeding mechanism 5, a cutter 6 mounted on the cutter holder, a power assembly for driving the cutter 6 and the pencil feeding mechanism 5 to work, and a control assembly for controlling the switch of the power assembly are arranged inside the main machine 1, the control assembly comprises a control main board 3 and a thickness adjusting dial 7 with at least two gears, a linkage is arranged at the bottom of the pencil feeding mechanism 5, an electric control box 2 is telescopically arranged at the bottom of the linkage, a hall switch 8 is arranged on the electric control box 2, the signal output end of the hall switch 8 is connected to the signal input end of the control main board 3, and the control main board 3 opens or closes the power assembly through a hall signal.

In this embodiment, as shown in fig. 2, the thickness adjustment dial 7 has two magnet mounting positions, which include a first magnet mounting position 71 and a second magnet mounting position 72, wherein magnets are mounted in both magnet mounting positions, and at least two magnets protrude from the thickness adjustment dial at different heights.

Wherein, one end of the thickness adjusting dial 7 extends out of the main machine 1, and the switching of at least two magnet installation positions is adjusted through finger operation.

As shown in fig. 2, the linkage member includes a top rod 12 and a push rod 11 mounted on the electronic control box, the bottom of the top rod 12 contacts with the upper end surface of the push rod 11, the bottom of the pencil point abuts against one side of the top rod 12, and the top rod 12 and the push rod 11 are pushed to descend by the pencil point. Because the protruding height of two magnets is different, when the nib descends, drive hall switch through the linkage piece and descend, this moment if thickness adjustment is in the magnet of high-order and is just facing hall switch on the driver plate, then hall switch senses output signal to control mainboard behind the magnet, by control mainboard control power component stop into the pen, cut the end of writing this moment, if want to obtain thinner nib, then as long as rotate the driver plate, make low-order magnet just facing hall switch, power component continues to carry the pen downwards this moment, stop work again when hall switch senses the magnet once more, consequently, the nib under this condition is thinner, with this thickness of adjusting the nib.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
