Problems solved by technology

[0002] There are two structures of the traditional pencil sharpener's pen inlet, one is the pen inlet that can only put a standard size pencil in a single specification; the other is the turntable pen inlet that can insert pencils of various sizes Turntables with round holes with different inner diameters are suitable for inserting pencils of different specifications. When sharpening pencils, you need to turn the turntable to select the corresponding inner holes, which is laborious, time-consuming, and inefficient.

Embodiment 1

[0025] Example 1: from figure 1 and figure 2 It can be clearly seen that the pencil inlet of the pencil sharpener that is suitable for pencils of different specifications includes a pencil inlet base composed of a pen inlet slider mounting base 1 and a seat cover 2, and the pen inlet slider is installed The seat 1 and the seat cover 2 are connected as a whole by screws (not shown in the figure).

[0026] The pen entry slider mounting base 1 and the seat cover 2 are provided with a corresponding central through hole 3, and the pen entry slider mounting base 1 around the central through hole 3 is equally provided with three elastic sliders for installation. The first groove rail 41, the second groove rail 42, and the third groove rail 43, the first groove rail 41, the second groove rail 42, and the third groove rail 43 are respectively provided with elastic sliders, and the top switch slider 7 And switch 8 is installed in the pen inlet base 1 of the outer end of the first gro...

Embodiment 2

[0032] Example 2: from Figure 5 , Figure 6 It can be clearly seen that the basic structure of the pencil sharpener pen inlet of this embodiment adapted to pencils of different specifications is the same as that of Embodiment 1, the only difference being that the elastic slider is as follows: Figure 7 As shown, one end of the slider 5 is provided with a straight surface 19 that forms a triangular writing opening 20 after closing. When the pencil is inserted into the flat surface 19 at the ends of the three sliders 5 to form a triangular pen opening 20, the inserted pencil forces the three sliders 5 to compress the spring 6 to expand the triangular pen opening 20, which satisfies the smooth insertion of the pencil for cutting. clamping requirements.

Abstract

A pencil sharpener pencil inlet matched with different specifications of pencils comprises a jacking switch sliding block and a switch, and is characterized in that the pencil sharpener pencil inlet further comprises a pencil inlet base composed of a pencil inlet sliding block mounting seat and a seat cover plate, and a center through hole is formed in the pencil inlet base; and at least three groove rails used for mounting of elastic sliding blocks are arranged in the pencil inlet sliding block mounting seat around the center through hole in an even division manner, and the elastic sliding blocks capable of forming the pencil inlet after being closed are arranged on the groove rails. By means of telescopic structures formed by the elastic sliding blocks in the pencil inlet base, the pencil inlet can be enlarged or shrunk along with inserted pencil thickness. The pencil sharpener pencil inlet is suitable for mounting of an existing pencil sharpener, during use, pencils of different specifications or different shapes can be inserted into the pencil sharpener pencil inlet without adjusting, the application range of the pencil sharpener is greatly widened, time is saved, operation isconvenient and easy, and work efficiency can be improved.

Description

technical field [0001] The invention relates to a pencil sharpener, in particular to a pencil inlet for a pencil sharpener adapted to pencils of different specifications. Background technique [0002] There are two structures of the traditional pencil sharpener's pen inlet, one is the pen inlet that can only put a standard size pencil in a single specification; the other is the turntable pen inlet that can insert pencils of various sizes Turntables with round holes with different inner diameters are suitable for inserting pencils of different specifications. When sharpening pencils, you need to turn the turntable to select the corresponding inner holes, which is laborious, time-consuming, and inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to make up for the above-mentioned defects of the prior art, and to provide a pencil sharpening machine adaptable to pencils of different specifications. [0004] The techni...
