Abstract
The utility model relates to a rotary pencil grinding sharpener for sharpening and grinding the wood rod pencils. The existing common pencil sharpeners have the defects that the pencil lead is easy to be broken off or split; the hand rolling machinery pencil sharpeners have the defects of large size, high price and carrying inconvenience. The utility model is characterized in that only the wood rod of the pencil is cut, and then the pencil is rotated in the inner friction surface of a taper ring in which a piece of abrasive paper or grinding sand is adhered thus the pencil lead is sharpened with a uniform circumference; the integration is the structure of a case; the case contains the pencil sharpener, the taper ring and the friction surface thereof; the scraps of pencils are stored in the case. The utility model has the advantages that rolling sharpening and grinding is convenient; the pencil lead is not cracked or broken; the sanitation and the cleanness of the environment can be kept; the carrying is convenient.
Description
The utility model relates to new stationery cutter, is used to roll up the ground wood rod pencil.Existing common pencil sharpener is easy to splitting and pinch off lead for retractable pencil, and hand mechanical pencil sharpener body is long-pending greatly, price is high, carry inconvenience.The purpose of this utility model be make when sharpening a pencil do not split, continuous lead for retractable pencil, and prolong life-span of pencil-knife, be easy to carry favourable health simultaneously.
The purpose of this utility model realizes in the following manner: the most advanced and sophisticated place of pencil sharpener taper hole blade is shortened, and the lead for retractable pencil sidepiece does not have blade, and volume is only cut rod when cutting.Hold pencil then and rub a few with the even sharpening of lead for retractable pencil circumference along a circular cone ring internal friction face revolution.
Principal character of the present utility model and implementation method are: the most advanced and sophisticated lead for retractable pencil sidepiece of the pencil sharpener taper hole of manufacturing does not have blade, makes the feasible volume of edge length and only cuts rod when cutting and do not cut lead for retractable pencil.Pencil sharpener is fixed in the lid inboard of establishing screw-socket, manufactures the cylinder box, screw-socket is established in cylinder box rear end, links to each other with the screw-socket lid, and pencil sharpener enters in the box.Cylinder box front inner wall is established circular cone anchor ring internal friction face, and fixedly sand paper or directly sticking abrasive sand is used for the sharpening lead for retractable pencil on the face.For making the lead for retractable pencil cleaning that grinds, also can be at circular cone ring internal friction face along establishing the flour milling of removing contamination in the circular cone ring that can wipe the lead for retractable pencil powder, material be plastics, rubber, cloth, paper one of them.The flute profile bayonet socket is established in the cylinder box front end outside, link to each other with the bayonet socket lid, the bayonet socket lid can rotate along the cylinder box, the bayonet socket lid center of circle is established volume and is cut the hole, so that pencil inserts the pencil sharpener in the box, establish the lead for retractable pencil hole of going round and round a millstone with circular cone ring internal friction face corresponding section on the bayonet socket lid, establish the grinding out of removing contamination with the flour milling corresponding section of removing contamination in the circular cone ring.As storage bits box, the box body profile can be according to appearance, the decoration of requiring attractive in appearance simultaneously for the cylinder box.The box body interior diameter reaches and can hold pencil sharpener, and lead for retractable pencil can be gone round and round a millstone effectively along circular cone ring internal friction face.The circular cone ring internal friction face and the flour milling of removing contamination can wash by water.Also can remove contamination in cylinder box two ends are established circular cone ring internal friction face, circular cone ring simultaneously flour milling and screw-socket, bayonet socket uses the flour milling at two ends respectively so that front and rear covers exchanges.
Accompanying drawing 1 is a perspective view of the present utility model, and accompanying drawing 2 is an internal structure detail drawing of the present utility model, and concrete device of the present utility model is shown in accompanying drawing 1,2: pencil sharpener ［ 1 ］, short angle of throat sheet ［ 2 ］, cylinder box body ［ 3 ］, pencil ［ 4 ］, bayonet socket lid ［ 5 ］, volume is cut hole ［ 6 ］, the lead for retractable pencil hole ［ 7 ］ of going round and round a millstone, the grinding out ［ 8 ］ of removing contamination, conical ring internal friction face ［ 9 ］, the flour milling of removing contamination ［ 10 ］, screw-socket lid ［ 11 ］, storage bits box ［ 12 ］, flute profile bayonet socket ［ 13 ］.
The utility model can be realized under the prior art condition.Its advantage is light for volume mill, do not split, continuous lead for retractable pencil, and sanitation and hygiene, easy to carry.
