Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.
As shown in Figure 2, described penknife, comprise an inside and be cavity and without the cylindrical housings 1 of upper surface, the inner ring of cylindrical housings 1 is provided with teeth groove 11, the bottom surface central authorities being positioned at described cylindrical housings 1 are also provided with a pillar 2 perpendicular to bottom surface, the bottom of described cylindrical housings 1 is provided with a lower carriage 3, lower carriage is divided into lower sheathed end 31 and lower external part 32, described lower sheathed end 31 is set on pillar 3, described lower external part 32 stretches out to the edge of cylindrical housings 1, the top of described cylindrical housings 1 is provided with a upper bracket 4, upper bracket is divided into sheathed end 41 and upper external part 42, described sheathed end 41 to be set on pillar 3 and to match with lower sheathed end 31, described upper external part 42 stretches out to the edge of cylindrical housings 1 and corresponding with lower external part 32, the end opens of described upper external part 42 has a through hole 421 matched with pencil holder, the adz block 5 of a band planing tool 6 is provided with between described upper external part 42 and lower external part 32, the two ends of described adz block 5 are movably arranged on external part 42 and lower external part 32 respectively, described adz block 5 be provided with penholder guiding taper hole and penholder guiding taper hole to enter the tip of the brushstyle of a writing or painting corresponding with the through hole 421 on upper external part 42, described planing tool 6 is arranged on the conical surface of penholder guiding taper hole, the blade of described planing tool 6 is parallel with the conical surface and embed penholder and lead in taper hole, as shown in Figure 3, a gear 7 matched with the teeth groove 11 on cylindrical housings 1 inner ring is also provided with between external part 42 with lower external part 32 on described, described gear 7 and adz block 5 synchronous axial system,
Lower carriage 3 of the present invention is also provided with side external part 33, described side external part 33 stretches out to an other lateral edges of cylindrical housings 1, described side external part 33 and lower external part 32 are located along the same line and side external part 33 are provided with balancing weight 8, add the balance of lower carriage 3 when rotating;
The bottom surface of cylindrical housings 1 of the present invention is provided with a circle concentric and protrude from the sliver 12 of bottom surface with its phase, correspond, the bottom of described lower external part 32 offers the guide-track groove 321 matched with sliver 12, described sliver 12 is positioned at guide-track groove 321, the bottom of described side external part 33 offers the guide-track groove (not shown in FIG.) matched with sliver 12 equally, described sliver 12 is positioned at its guide-track groove, this serves a spacing effect to lower carriage 3 when rotating, and also enhances stability when lower carriage 3 rotates simultaneously.
During use, one holds cylindrical housings 1, another holds pencil and it is inserted in penholder guiding taper hole from through hole 421, while pencil is exerted a force downwards, while the inner ring of gear 7 around cylindrical housings 1 is rotated, inner ring due to cylindrical housings 1 is provided with teeth groove 11 and adz block 5 and gear 7 synchronous axial system, so gear 7 rotates a circle around the inner ring of cylindrical housings 1, gear 7 self can rotate some weeks, namely adz block 5 self can rotate some weeks, so the chip efficiency of adz block 5 pairs of pencils increases greatly.
The structure of structural design imitation planetary gear of the present invention makes chip efficiency obtain to be increased greatly, and operation is quite simple, and cost is also lower.
