Detailed Description
The utility model provides a pencil point thickness adjusting device of pencil sharpener, includes rotates the hand crank 1 of installing on the pencil sharpener, the rotation seat 101 of hand crank 1 in the middle of seted up interior, outside both sides link up pencil perforation 102, the sliding tray 103 that the outside of rotation seat 101 was seted up, sliding tray 103 sliding connection has nib thickness to adjust slider 2, be equipped with on the nib thickness adjust slider 2 and adjust ladder 201, adjust ladder 201 towards pencil perforation 102 setting, adjust ladder 201 and include a plurality of step faces, a plurality of step faces are different from pencil perforation 102's distance, a plurality of step faces are arranged according to the distance order of distance from pencil perforation 102.
As shown in fig. 1 and 2, the nib thickness adjusting apparatus of the pencil sharpener of the present utility model is mounted on the pencil sharpener, and is the same as the original pencil sharpener in that: the pencil is inserted into the pencil hole of the pencil sharpener, the pen point end of the pencil can extend into the pencil through hole 102, the hand crank handle 1 is rotated by hand, and the hand crank handle 1 drives the blade in the pencil sharpener to cut the pen point of the pencil.
During the pencil sharpening process, the top end of the pencil point is pressed onto the step surface of the adjusting step 201.
When the thickness is regulated, the regulating slide block 2 is only required to slide up and down, and when the step surfaces at different positions of the regulating step 201 in the regulating slide block 2 are aligned with the pencil through holes 102, the thicknesses of the pen points of the pencils cut out are different.
Because the step surfaces at different positions are different in distance from the pencil through hole 102, when the distance is short, the length of the pencil which can extend into the pencil sharpener is short, and the thicker the pencil point of the sharpened pencil is; conversely, the farther the distance, the longer the pencil can extend into the sharpener, and the thinner the sharpened tip of the pencil.
The sliding groove 103 passes over the pencil through hole 102.
The outer side of the rotating seat 101 is clamped with a seat cover 3, and the adjusting slide block 2 is arranged between the seat cover 3 and the rotating seat 101 in a sliding manner.
One end of the adjusting slide block 2 is provided with a push-pull head 202 for driving the adjusting slide block 2, and the push-pull head 202 is exposed to the outside of the seat cover 3. Facilitating the sliding of the adjusting slide 2 by the push-pull head 202.
The rotating seat 101 is provided with a clamping groove 104 for clamping the seat cover 3, and the seat cover 3 is provided with a buckle 301 which is clamped into the clamping groove 104. The assembly of the seat cover 3 is facilitated. The edge of the seat cover 3 is also provided with a groove for avoiding the push-pull head 202.
The step surface edge of the adjusting step 201 is provided with a flange 203. The flange 203 prevents the tip of the pencil from accidentally sliding onto the adjacent step surface.
The inner side of the rotating seat 101 is matched with the cutter core assembly 4, and the cutter core assembly 4 is internally and movably provided with a push rod 5 extending into the pencil perforation 102.
The push rod 5 is sleeved with a spring 6, one end of the spring 6 is propped against the push rod 5, and the other end is propped against the cutter core assembly 4.
As shown in fig. 3 and fig. 4, the pencil lead assembly 4 in this scheme is similar to the prior art, when the pencil to be sharpened stretches into the pencil lead assembly 4, the front end of the pencil is pushed onto the push rod 5, the push rod 5 is pushed to one side of the adjusting slide block 2, and as mentioned above, when the thickness is adjusted, the adjusting slide block 2 only needs to slide up and down, and when the step surfaces in different positions of the adjusting step 201 in the adjusting slide block 2 are aligned with the pencil perforation 102, the depth of the push rod 5 stretching into the pencil perforation 102 is different, and the thicknesses of the pen points of the sharpened pencil are also different, so that the purpose of adjusting the thicknesses of the pen points can be achieved.
