Description

multifunctional pencil sharpener

technical field

The utility model relates to the technical field of stationery, in particular to a multifunctional pencil sharpener.

Background technique

A pencil is a tool for writing and drawing. It includes a wooden barrel and a graphite refill. In order to facilitate writing, the head of the barrel needs to be sharpened to expose the inner refill before using the pencil. In the past, many tools such as utility knives were used to sharpen pencils. Common knives are very sharp, and pencils are not easy to control, and it is very easy to cut fingers.

In the prior art, in order to improve the safety of sharpening pencils and facilitate people to sharpen pencils, corresponding pencil sharpeners and pencil sharpeners have appeared, which can sharpen pencils by rotating the pencils. Although it is much more convenient to sharpen pencils than knives, the large amount of pencil sharpening and dust produced by sharpening pencils can easily cause pollution and need to be dealt with in time. At the same time, the blade of the pencil sharpener is exposed, which is easy to rust and has a potential safety hazard. The traditional pencil sharpener is small in size and easy to lose. In addition, due to the easy-erase nature of pencils, pencils are generally used with erasers, and during use, erasers are easily lost due to their small size, causing inconvenience. In addition, a large amount of debris will be generated during the use of the rubber, resulting in garbage, which is not easy to clean. The functions of existing pencil sharpeners and pencil sharpeners are relatively single.

In a preferred embodiment of the present invention, the storage layer 1 , the pencil roll layer 2 and the cleaning layer 3 are all cylindrical with the same bottom diameter, and the storage layer 1 and the pencil roll layer 2 are screwed together. Specifically, the groove bottom of the groove body 102 of the storage layer 1 is formed with a screwing groove (not shown in the figure), and the side wall of the screwing groove has an internal thread (not shown in the figure), and the roll The main body of the pen layer 2 is formed with a threaded portion 205 whose diameter is smaller than the diameter of the main body and is equivalent to the diameter of the threaded groove, and the outer wall of the threaded portion 205 has an external thread matching the internal thread, Thus, the two can be screwed together. Of course, in other embodiments, the storage layer 1 and the pencil roll layer 2 may also be connected together by other suitable means, such as hinged, snap-connected and the like.

In addition, in order to facilitate the user to separate the storage layer 1 from the pencil roll layer 2, a group of raised ribs 107 are arranged on the outer wall of the groove body 102 at equal intervals to increase the frictional force of the outer wall. It is convenient for the actual use of the user.

As shown in FIG. 7 , the main body of the pencil sharpening layer 2 is in the shape of a groove, and a pencil sharpener 201 is provided at the bottom of the groove of the main body. A through hole 202 communicates with the pencil sharpener 201 .

The bottom of the pencil pencil layer 2 has a connecting wall 203 with a diameter smaller than the diameter of the main body area. The connecting wall 203 has two symmetrically arranged clamping blocks 204. The block 204 is matched with the concave portion 301 , and the clamping block 204 is clamped with the concave portion 301 . Specifically, as shown in FIGS. 4 , 5 and 8 , the concave portion 301 is L-shaped, and the width of the concave portion 301 is the same as the width of the locking block 204 . The working principle is as follows: after the block 204 is vertically placed into the vertical part 3011 of the recess 301 , the cleaning layer 3 or the pencil-writing layer 2 is rotated, so that the block 204 slides into the recess 301 . Horizontal part 3012, so that the cleaning layer 3 and the pencil roller layer 2 are snapped together; when the cleaning layer 3 needs to be disassembled, reversely rotate the cleaning layer 3 or the pencil roller layer 2, so that the The blocking block 204 moves to the bottom of the vertical portion 3011, and then separates the cleaning layer 3 downward.
