Description
The utility model is the adjustable pencil with wound cutter of using for pencil user roll cutting pencils such as student or engineers and technicians.
Through the interrelated data retrieval, also there be not the adjustable pencil with wound cutter identical at present with the utility model structure.The method that the pencil user sharpens a pencil has pencil with wound cutter volume to cut or cut with pocket knife is manual.At present used pencil with wound cutter all is fixed pencil with wound cutter, the pen core tubbiness that its volume is cut, and anti-writing and cause having the weak point of frequent volume pen not, hand-held pocket knife cutting pencil, though can cut pen core length arbitrarily, unsatisfactory aspect quality, speed and health.
The purpose of this utility model is to overcome the weak point that present fixed pencil with wound cutter volume is cut and hand-held pocket knife cuts pencil, provides a kind of volume to cut the length-adjustable adjustable pencil with wound cutter of pen core.
The purpose of this utility model is achieved through the following technical solutions.Adjustable pencil with wound cutter is by tool rest, blade, hold-down screw, eccentric wheel is formed, one bellmouth that links to each other with cylindrical hole is arranged on the tool rest, blade is fixed on the tool rest with the locating hole that hold-down screw passes on the blade, eccentric wheel is contained in the below of blade front end, eccentric wheel is contained on the camshaft, the center of camshaft and the edge of a knife of blade are perpendicular, eccentric wheel rim and blade contact, the edge of a knife of blade and the conical surface of bellmouth are tangent, locating hole is partially after the middle-end of blade is inclined to one side on the blade, one blade locating slot is arranged on the tool rest, have on the vertical direction of blade locating slot one with blade on the corresponding screwed hole of locating slot.
Facts have proved that the utility model integrates the advantage of hand-held pocket knife cutting pencil and fixed pencil with wound cutter roll cutting pencil, it is fast to have pen core adjustable length, quality height, speed that volume cuts out, advantages such as sanitation and hygiene.
Accompanying drawing is a structural representation of the present utility model, and Fig. 1 is a front view, and Fig. 2 is the A-A cutaway view, among the figure: the 1-tool rest; The 2-blade; The 3-hold-down screw; Bellmouth on the 4-tool rest; Cylindrical hole on the 5-tool rest; The 6-eccentric wheel; The 7-camshaft; 8-eccentric wheel axle head knob.
Below in conjunction with description of drawings operating position of the present utility model, pencil put forth one's strength from bellmouth push and Propelling pencil with sharpener in cap or adjustable pencil with wound cutter, the pen core of cutting is a little long if desired, then rotate eccentric wheel axle head knob, eccentric wheel is contacted away from the wheel rim and the blade of core wheel, it is the longest then to roll up the pen core of cutting out, if eccentric wheel is contacted near the wheel rim and the blade of core wheel, it is the shortest then to roll up the pen core of cutting out, because the eccentric wheel wheel rim changes from the distance of core wheel, so when rotating eccentric wheel axle head knob, the variable-angle of blade perk, thereby roll up the adjustable length of cutting out pen core, its adjustable extent is best in 5-10 millimeter scope.When making the utility model, tool rest with moulding for well.
