Abstract
The utility model discloses a pencil sharpener with an adjustable diameter. The pencil sharpener with an adjustable diameter adopts the structure that an adjusting sleeve is arranged behind a taper hole, a pencil inlet hole on the adjusting sleeve is provide with an eccentric structure, and the utility model can adjust the position of the pencil inlet hole, so as to adjust distance between a rotary precession shaft line and an edge line when the pencil is rotatablely sharpened; therefore, the purpose of adjusting the diameter of the tip end of the pencil is realized. With the adoption of the adjusting mode, people can produce the pencil sharpener with an adjustable diameter which is suitable for pupils in low grades, and the utility model has the characteristics of lost cost and practicability.
Description
A large amount of at present general use volume gravers that use are because its edge line and pencil precession axis are the intersecting straight lines in space, so there is the uncontrollable problem of its nib diameter.
For addressing this problem, in Chinese patent 96224063.X, proposed to adopt the solution of θ angle adjusting mechanism.But this θ guiding mechanism need adopt screwdriver to adjust instrument, needs more careful operation again, and particularly lower pupil is difficult for finishing, so its practical application is restricted.
The purpose of this utility model is to provide a kind of volume to tip of a pencil to cut the path transfer pencil sharpener that diameter carries out more convenient adjustment.
The purpose of this utility model is achieved in that after knife rest is tapered the adjustment that cooperates with knife rest with cylinder puts, and the pencil hand-hole with the different axle center of cylinder is set.When rotating the adjustment cover, the pencil hand-hole is with respect to the cylinder eccentric rotary displacement of adjusting cover, the pencil precession axis that pencil hand-hole and pilot hole leading portion when pilot hole leading portion (no and taper hole) determined and the relative position of edge line are changed, the distance that is edge line and pencil precession axis is conditioned, changed the gorge circle diameter of the tip of a pencil that carries out the single leaf bilateral curved rotation surface shaping, thereby made tip of a pencil end diameter Φ adjusted.
The utility model utilizes the pencil hand-hole in the former design, on the basis that does not change guide function, increased new path transfer function, saved the part manufacturing and the structure processing of former guiding mechanism simultaneously, both reduced cost, path transfer again can be easily, and (as with a coin) realizes.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Accompanying drawing 1 is the structural representation of adjustment cover of the present utility model.
Accompanying drawing 2 is single leaf hyperbolic rotoforming face tip of a pencil schematic diagrames that the utility model rolls out.
Accompanying drawing 3 is the utility model top cross-sectional view.
The axial line (6) that accompanying drawing 1 is shown with and adjusts cover (1), adjusts groove (2), pencil hand-hole (3), cylinder (4), pencil hand-hole axial line (5), cylinder (4), and the axial line (6) of cylinder (4) and the distance (e) between the pencil hand-hole axial line (5).
Shown in the accompanying drawing 2, Φ is the end diameter with single leaf hyperbolic rotoforming face tip of a pencil.
Shown in the accompanying drawing 3, on knife rest (7), with the fixing blade (9) of blade hold-down screw (8), (θ) be the initial fixation angle of blade (9), reference column (10) on the knife rest (7) is gone up the automatic location pendulum (11) of location, taper hole (12) pilot hole leading portion (13) afterwards, and adjust cover (1).Pilot hole leading portion (13) and taper hole (12) are preferably coaxial with the cylinder of adjusting on the cover (1) (4).
Claims (1)
1. path transfer pencil sharpener.Have blade (9), blade hold-down screw (8), knife rest (7), be fixed in automatic location pendulum (11), knife rest (7) that pendulum post (10) on the knife rest (7) and pendulum post (10) go up to install and go up the end of going into of taper hole (12) and have pilot hole leading portion (13), also can not have pilot hole leading portion (13), it is characterized in that: afterwards with on cylinder (4) and the adjustment cover (1) that knife rest (7) cooperates, the pencil hand-hole (3) with the different axle center of cylinder (4) is set at the taper hole (12) of knife rest (7).
