Detailed Description

As shown in fig. 1-8, the rotating self-sharpening pencil holder comprises a cylindrical inner barrel 1, wherein the inner diameter of the inner barrel 1 is slightly larger than the diameter of a pencil, the end part of the pencil can be inserted into the inner barrel 1, a rotating cap 11 is fixed at the top end of the inner barrel 1, and an annular protrusion 12 playing a clamping role is arranged at the bottom end of the rotating cap 11. Set up two bar holes 14 that set up along 1 length direction symmetry of inner tube on the inner tube 1, be equipped with the centre gripping lid 2 that can reciprocate in the inner tube 1, be fixed with the supporting shoe 21 that the symmetry set up on the lateral wall of centre gripping lid 2, two supporting shoe 21 sliding connection are in the bar hole 14 that corresponds, and bar hole 14 all extends to two supporting shoes 21, and the surface of supporting shoe 21 all is equipped with the screw thread. The lower extreme of centre gripping lid 2 is equipped with the opening, is equipped with a plurality of evenly distributed's the grip block 22 that is used for fixed pencil in the opening, the quantity of grip block 22 is four at least, encloses into the space of placing of fixed wooden pencil tip between each grip block 22, and grip block 22 adopts the rubber material that all has flexible function, and the upper end of wooden pencil injects the inner tube 1 during the use in, and the upper end of wooden pencil is pegged graft in placing the space, and under the effect of grip block 22 elasticity, wooden pencil is fixed. The outside of inner tube 1 is equipped with urceolus 3, and the annular groove 31 of mutually supporting with annular bulge is seted up to the upper end of urceolus 3, urceolus 3 and rotatory cap 11 rotatable coupling, and seted up the internal thread on the inside wall of urceolus 3, two supporting shoes 21 respectively with 3 threaded connection of urceolus, rotate rotatory cap 11, supporting shoe 21 moves up and down along strip shape hole, centre gripping lid 2 drives wooden pencil and shifts out inner tube 1. The lower extreme of urceolus 3 is equipped with utensil screwed connector 32, and connector 32 plays the connection effect, threaded connection has nib 4 on the connector 32, and the bottom of nib 4 is equipped with the lead and detains hole 41, is equipped with the blade 42 that is used for selling the pencil in the nib 4, is close to blade 42 and goes out to offer and be used for supplying saw-dust exhaust to go out bits hole 43.

Preferably, the outer cylinder 3 has an inner diameter greater than an outer diameter of the inner cylinder 1, the inner cylinder 1 being rotatable relative to the outer cylinder 3.

The rotating cap 11 is provided with anti-skid lines for friction.

Preferably, the nib 4 is funnel-shaped, the blade 42 is obliquely arranged downwards, the chip discharging hole 43 is strip-shaped and parallel to the blade 42, so that wood of the wooden pencil can be conveniently chipped off to leak out the pencil lead, and the chip discharging hole 43 is strip-shaped so that chipped wood chips can be conveniently discharged from the nib 4.
