Detailed description of the invention
The utility model is further described by specific embodiment below in conjunction with accompanying drawing.
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,
