Fig. 1 is a schematic structural view of a multifunctional pencil sharpener according to embodiment 1;

FIG. 2 is a front view of the multifunctional pencil sharpener of embodiment 1;

fig. 3 is a side view of the multifunctional pencil sharpener according to embodiment 1.

Detailed Description

Example 1

As shown in fig. 1 and 2, a multifunctional pencil sharpener with a capsule-shaped structure is provided, which includes a blade 1, a conical winding drum 2 for feeding a pencil, and a sleeve 3 for accommodating the blade and the conical winding drum, the conical winding drum 2 is designed with reference to the conical winding drum of the pencil sharpener in the prior art, in order to control the position of the blade 1, a first baffle 41 for fitting the surface of the blade is arranged in the sleeve 3, the edge of the blade is higher than the top of the baffle and corresponds to the side opening of the conical winding drum (with reference to the structural design of the pencil sharpener in the prior art), so that the edge of the blade can provide a pencil sharpening function for a pencil extending into the conical winding drum, and the tail end of the conical winding drum has a space 5 for letting out the same pencil scraps as the pencil sharpener in the prior art. The head end of the blade is close to the conical winding drum, the surface of the tail end of the blade is vertically connected with a pull rod 6, the pull rod 6 extends out of the sleeve 3, a linear track notch 31 which can be pushed out of the sleeve along a straight line by driving the blade through operating the pull rod is formed in the sleeve 3, and the sleeve 3 is provided with an outlet 32 at the position corresponding to the head end of the blade to allow the blade 1 to extend out.

In order to ensure the operation stability of the blade during pencil sharpening, linear sliding extension and use as an art knife, a second baffle 42 parallel to the first baffle 41 is arranged in the sleeve 3 to clamp the blade, the two baffles limit the degree of freedom of the blade in the direction perpendicular to the surface of the blade, the blade cannot slide in the direction due to the pressure of a pencil during pencil sharpening, and the blade cannot swing during sliding and use as an art knife. The first baffle and the second baffle are fixed on the inner wall of the sleeve.

Further, in order to prevent the blade from retreating backwards during operation, a limiting plate 43 is further connected between the first baffle 41 and the second baffle 42 at the corresponding position of the back of the blade, the back of the blade 1 is attached to the limiting plate 43, at the moment, the blade only slides along the length direction of the blade possibly, and the operational reliability of the blade can be completely ensured.

In this embodiment,

blade

1 and 3 axis parallel arrangement of sleeve, it is regular along the axis direction to stretch out when the blade stretches out the sleeve to be convenient for, prevents to stretch out the problem that is unfavorable for the operation because of the slant. Of course, with this arrangement of the blade, the tapered roller needs to be disposed at a slightly more inclined angle than the tapered roller of the prior art sharpener.

In order to facilitate the user to operate the pull rod quickly and regularly, the pull rod 6 extends out of the end part of the sleeve and is provided with the sliding button 7, the size of the sliding button 7 is larger than that of the track gap 31, the sliding button 7 is in contact with the surface of the sleeve 3 in a fitting mode, and the user only needs to push the sliding button to control the forward movement and the backward movement (namely the extension and the retraction of the blade) of the pull rod.

The lengths of the first baffle and the second baffle in the sleeve are determined according to actual conditions, and the blade is limited by the first baffle and the second baffle in the processes of sharpening the pencil and sliding to have swinging freedom along the vertical direction.

The sleeve afterbody still is connected with closing cap 8, the closing cap is used for receiving the sweeps, as shown in fig. 3, the closing cap is the step structure, the sleeve afterbody has the concave recess with the step structure adaptation of closing cap, see from a certain view direction, the closing cap is the zigzag with telescopic combination department connecting wire, this step design has increased the whole aesthetic feeling of pencil sharpener on the one hand, on the other hand also does benefit to the step department of reserving the sweeps at the closing cap, the user is when the sweeps need to be abandoned, can steadily take out the closing cap under the horizontal state that the pencil sharpener kept the posture of cutting, and need not earlier catch up the sweeps to closing cap department with the vertical placing of pencil sharpener and take out the closing cap again.

The functions of the pencil sharpener and the art designing knife are integrated on one blade, and when the blade is arranged in the pencil sharpener, the pencil sharpener capable of collecting pencil scraps and inserting a pencil is used; when the pull rod is pushed to enable the blade to extend out of the sleeve, the exposed part of the blade can be used as an art designing knife, the utilization rate of the blade is increased, and the multifunctional function of the pencil sharpener is realized.

The utility model discloses not limit to foretell specific structure or connected mode, as long as have the pencil sharpener that will cut a pencil and art designer's sword function integration together just fall within the protection scope of the utility model.
