Abstract

Provided is an electric pencil sharpener. The electric pencil sharpener comprises a cover plate (1). Through holes (2) for pencils penetrating through are formed in the cover plate (1). A clamping mechanism (3) for preventing pencils from rotating circumferentially is arranged at the position of a through hole (2) on the front end surface of the cover plate (1). Compared with the prior art, due to the fact that the clamping mechanism for preventing pencils from rotating circumferentially is arranged at the position of the through hole on the front end surface of the cover plate, when pencils are inserted into the through holes, the clamping mechanism is a first place pencils need to pass through, and when pencils are inserted into a limiting position, pencils are limited in a circumferential direction under the influence of the clamping mechanism, therefore, when the electric pencil sharpener is in work, pencils can be sharpened without users holding pencils, and even if users are holding pencils, the condition that users can not hold pencils does not happen, and blister raising or skin peeling of hands of users can not be caused, and consequently the electric pencil sharpener is excellent in using safety performance.

Description

Electric pencil-sharpening unit

Technical field

The utility model belongs to the stationery field, particularly relates to a kind of electric pencil-sharpening unit.

Background technology

At present, the electric pencil-sharpening unit of prior art is when sharpening a pencil, need one of user to hold pencil, otherwise when electric pencil-sharpening unit starts, pencil will rotate together along with knife rest, can't reach the purpose of cutting pen, and electric pencil-sharpening unit is that the pupil is in usefulness mostly, and pupil's health is in the stage of development, strength on hand is less, and then the electric pencil-sharpening unit of prior art tends to occur holding the incessantly situation of pencil in use, and then cause user's hand the situation of bubbling or peeling to occur, therefore the safety in utilization of the electric pencil-sharpening unit of prior art is relatively poor.

The utility model content

The utility model provides preferably electric pencil-sharpening unit of a kind of safety in utilization for above problem.

The utility model overcomes the above problems used technical scheme: a kind of electric pencil-sharpening unit with following structure is provided, it comprises cover plate, described cover plate is provided with the through hole that passes for pen, and the position of described cover plate upper surface through hole is provided with the clamp mechanism that prevents that pen from circumferentially rotating.

After adopting above structure, compared with prior art, the utility model since on the cover board the position of end face through hole be provided with a clamp mechanism that prevents that pen from circumferentially rotating, when then penholder enters in the through hole, must pass through first clamp mechanism, when pen is inserted into spacing place, start writing by circumferentially spacing in the effect of clamp mechanism, therefore when electric pencil-sharpening unit was worked, the user need not to hold pen by hand, also can realize cutting the purpose of pen, even and the user grasps pen, the incessantly situation of pencil also can not occur holding, then also just can not occur causing user's hand the situation of bubbling or peeling to occur, therefore safety in utilization of the present utility model is better.

As improvement, described clamp mechanism comprises the clamp that two elastomeric materials make, the cross section of described clamp is " ∞ " shape, the two ends of two " ∞ " shape clamps are rotationally connected respectively on the cover board, the axis of described two clamps is on same level and parallel, described through hole is between two clamps, vertical range between described two " ∞ " shape clamp recess bottom is less than the diameter of through hole, then the clamp mechanism of this structure is simple in structure, rely on self the characteristic of strain of elastomeric material to come pen is carried out circumferentially spacing fully, and there is not unnecessary frame for movement, dependability and service life are all better, and cost is also lower.

As further improvement, the outer peripheral face of described clamp recess is provided with some the annular protrusions that increase frictional force, so that the frictional force between pen and the clamp is larger, so that pen is difficult for rotating more when actual cut, stability in use and security were better after then annular protrusion arranged.

Description of drawings

Fig. 1 is the structural representation of the utility model electric pencil-sharpening unit.

Fig. 2 is the top view of Fig. 1.

Fig. 3 is the upward view of Fig. 1.

As shown in the figure: 1, cover plate, 2, through hole, 3, clamp mechanism, 4, clamp, 5, annular protrusion.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

Such as Fig. 1, Fig. 2 and a kind of electric pencil-sharpening unit shown in Figure 3, it comprises that cover plate 1(also comprises other parts certainly, but owing to not relating to the inventive point of the invention, therefore do not repeat them here, in the accompanying drawings also for illustrating), described cover plate 1 is provided with the through hole 2 that passes for pen, and the position of described cover plate 1 upper surface through hole 2 is provided with the clamp mechanism 3 that prevents that pen from circumferentially rotating.

Described clamp mechanism 3 comprises the clamp 4 that two elastomeric materials make, general clamp 4 is made by rubber, the cross section of described clamp 4 is " ∞ " shape, also can be regarded as down " 8 " font, and the profile of clamp 4 also can be regarded as the structure of Pear-Shaped, the two ends of two " ∞ " shape clamps 4 are rotatably connected on respectively on the cover plate 1, the axis of described two clamps 4 is on same level and parallel, described through hole 2 is between two clamps 4, also can be regarded as through hole 2 at two clamps 4 between the projection on the cover plate 1, vertical range between described two " ∞ " shape clamp 4 recess bottom is less than the diameter of through hole 2, distance between the outer surface that namely two clamps 4 are relative is all less than the diameter of through hole 2, and purpose is exactly for can be with pen clip between the recess of two clamps 4.

The outer peripheral face of described clamp 4 recess is provided with some the annular protrusions 5 that increase frictional force.

Above embodiment only is preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly changes in the utility model rights to independence claimed range, all belongs to the utility model protection domain.
