Detailed Description

As shown in fig. 1 to 6: the multifunctional pencil sharpener tool rest consists of a tool rest base 1, a pencil containing body 2, a hob 3, a hob shaft pin 4, a hob shaft 5, an over-sharpening preventing screw 6 and a pencil point conical included angle adjusting screw 7; an inner gear ring is arranged at the left end of a tool rest base (1), the inner gear ring is combined with the tool rest base (1) into a whole, a gear of a hob (3) is meshed with the inner gear ring of the tool rest base (1), an anti-over-cutting screw (6) is arranged at the central axis of the right end of a pen containing body (2), a nib cone included angle adjusting screw (7) is arranged in the radial direction, the upper end of the nib cone included angle adjusting screw (7) is connected with the right end of a hob shaft (5), the left end of the hob shaft (5) is fixed on one side of the pen containing body (2) through a hob shaft pin (4), the gear of the hob (3) is arranged at the left end of the hob (3) and is combined with the hob shaft screw into a whole, the anti-over-cutting shaft screw (6) at the central axis of the right end of the pen containing body (2) is rotated clockwise, the anti-over-cutting shaft screw (6) can be integrally moved left and right, the cone included angle adjusting screw (7) at the radial position of the right end of the pen containing body (2) can be rotated, and the included angle between the central axis of the hob shaft (5) and the central axis of the pen containing body (2) can be changed.

When the pen holder 2 rotates around the central axis thereof, the gear of the hob 3 engaged with the annular gear of the fixed tool rest base 1 rotates around the hob shaft 5 and also revolves around the central axis of the pen holder 2, because the hob 3 and the gear thereof are integrated, the hob 3 and the gear thereof rotate coaxially, in the same direction and synchronously, and in the same way, the hob 3 rotates around the hob shaft 5 and also revolves around the central axis of the pen holder 2, thereby realizing the cutting of the pen point cone.

The thickness of the pen point is realized by rotating the over-cutting prevention screw 6 at the central axis of the right end of the pen containing body 2 clockwise before the cutting process, moving the over-cutting prevention screw 6 to the leftmost side integrally, then rotating the pen point conical included angle adjusting screw 7 at the radial position of the right end of the pen containing body 2, dragging the roller shaft 5 to swing up and down around the roller shaft pin 4 by the pen point conical included angle adjusting screw 7, changing the radial distance between the right end of the roller shaft 5 and the central axis of the pen containing body 2, namely changing the included angle between the central axis of the hob 3 and the central axis of the pen containing body 2 (double included angle, namely pen point conical included angle), and when the pen points enter the same depth in the pen containing body 2 (in this case, 22 mm), the pen point is thinner when the included angle between the central axis of the hob 3 and the central axis of the pen containing body 2 is larger (clockwise rotating the conical included angle adjusting screw 7), otherwise, the pen point is thicker.

Before the cutting process, the over-cutting prevention screw 6 at the central axis of the right end of the pen containing body 2 is rotated anticlockwise, the over-cutting prevention screw 6 is integrally moved right to a required pen core cylinder length position (which can be adjusted between 0 mm and 20 mm in the present case), then the pen point conical included angle adjusting screw 7 at the radial position of the right end of the pen containing body 2 is rotated, the pen point conical included angle adjusting screw 7 drags the hob shaft 5 to swing up and down around the hob shaft pin 4, the radial distance between the right end of the hob shaft 5 and the central axis of the pen containing body 2 is changed, namely, the included angle (double included angle, namely pen point conical included angle) between the central axis of the hob 3 and the central axis of the pen containing body 2 is changed, and the pen point conical included angle adjusting screw 7 is rotated anticlockwise, so that the radial distance between the right end of the hob shaft 5 and the central axis of the pen containing body 2 is maximized, and the diameter of the cut pen point pen core cylinder is also maximized (which is 4 mm in the present case); the pen point pen cores with different cylinder diameters and lengths can be cut by combining and adjusting the over-cutting prevention screw 6 and the pen point conical included angle adjusting screw 7.

The above description is only for the purpose of illustrating embodiments of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents and improvements made within the spirit and scope of the present invention should be included in the claims.
