Abstract
The utility model relates to a novel adjustable pencil sharpener. A cylindrical guide hole is arranged after a conical guide hole, an upper blade which is longer than the conical guide hole and a lower blade which is longer than the conical guide are respectively arranged on the upper end of the conical guide hole and the lower end of the conical guide hole, and a triangular adjusting piece is arranged in the included angle on the front end of two blades. Thus, a pencil can be rotated in the guide hole stably without damaging the lead core. The cross angle of the two blades can be changed through the adjusting piece to cut the point of the lead with different thickness. Compared with the traditional pencil sharpener, the speed of cutting the pencil can be improved by one time.
Description
The utility model relates to a kind of pencil sharpener, particularly a kind of adjustable pencil sharpener.
The basic structure of pencil sharpener is at present, has a side of the fixture of taper guide hole to have a long permeable slot at one, fixes a blade in the outside of long permeable slot.Because the guide hole of such pencil sharpener is too short, and has only a blade, and is very unstable when pencil is rotated in guide hole, disconnected to lead for retractable pencil is coughed up by blade in the guide hole of being everlasting.
Purpose of design of the present utility model is to provide a kind of novel adjustable pencil sharpener to society.It has overcome the defective of traditional pencil sharpener, and in use pencil can very stably rotate in guide hole, can not damage lead for retractable pencil, and by regulating the plumbous point that can also cut out different thicknesses, the speed of cutting pen simultaneously is also fast again than traditional pencil sharpener.
The utility model is to be realized by following technical scheme.One cylindrical section shape guide hole is arranged in the back of taper guide hole.On the inclined-plane of two relative positions two long permeable slots are arranged about the taper guide hole, be fixed with two blades up and down in the outside of two long permeable slots respectively.Because the length of two blades all grows the length of taper guide hole, so two blades intersect to form an angle relative with the taper guide hole before the taper guide hole.The wide part that goes out of all oriented blade one side of the front end of two blades.A leg-of-mutton regulating part is arranged in the angle of two blade front ends.
Describe the utility model in detail below in conjunction with accompanying drawing and embodiment.As shown in the figure, Fig. 2 is a cutaway view, and Fig. 1 is a upward view, and Fig. 3 is a vertical view.Structure of the present utility model comprises a mount body 1, cutter 2, bottom knife 3, triangle regulating part 4 and adjusting knob 18.A taper guide hole 5 is arranged in mount body 1, and the rear portion of taper guide hole 5 is cylindrical shape guide holes 6.On the inclined-plane of two relative positions up and down of taper guide hole 5, have two long permeable slots---go up long permeable slot 7 and following long permeable slot 8(as shown in Figure 2).Outer inclined-plane along taper guide hole 5 on last long permeable slot 7 right sides is fixed with cutter 2, and the outer inclined-plane along taper guide hole 5 below the left side of following long permeable slot 8 is fixed with bottom knife 3.The length of cutter 2 and bottom knife 3 all grows the length of taper guide hole 5, and intersects before taper guide hole 5, forms an angle relative with taper guide hole 5, (as shown in Figure 2).The wide part 10 that goes out of oriented blade 9 one sides of cutter 2 front ends has a small gap 11 thereafter.The wide part 13 that goes out of oriented blade 12 1 sides of the front end of bottom knife 3 has a small gap 14 thereafter, (shown in Fig. 1,3).In the formed angle of front end of the front end of cutter 2 and bottom knife 3, a leg-of-mutton regulating part 4 is arranged, a screwed hole 15 is arranged on its front end face.On the main body 1 relative an open-work 16 is arranged with screwed hole 15.An adjusting knob 18 that has bolt 17 is arranged in the outside of open-work 16.Adjusting knob 18 passes open-work 16 and matches with screwed hole 15 on the regulating part 4.A fastener 19 that prevents that adjusting knob 18 from deviating from, (as shown in Figure 2) are arranged in the inboard of open-work 16.
In order to make penholder rotation more stably in guide hole, the inwall of cylindrical shape guide hole 6 can be made thread-shaped.
20,21 is hold-down screw.
Operating position of the present utility model is as follows.Pencil is inserted clockwise direction rotation in the guide hole 6, and cutter 2 and bottom knife 3 can cut pencil simultaneously.If desired pencil-lead is cut carefully slightly, can counterclockwise rotate adjusting knob 18, regulating part 4 is moved backward under the effect of screwed hole 15, at this moment, small gap 11 on the cutter 2 and the gap smaller between the small gap 14 on the bottom knife 3, the lead for retractable pencil of cutting out is just thinner.If opposite spin adjusting knob 18 can make regulating part 4 move forward, this moment, small gap 11 became big with the gap of small gap 14, can cut out thicker lead for retractable pencil.
As mentioned above, the utility model has reached purpose of design.
