Fit tolerance grade between bottom surface and penholder, so that casing can only be displaced from bottom to top.It is further preferred that the casing of falling triangular platform
Three outer surfaces respectively there is a hole 71, index finger finger pulp, thumb finger pulp and the middle finger finger pulp side through hole of user are held
Handle penholder or casing.Preferably as another step, it is provided in three outer surfaces of the casing of falling triangular platform vertical anti-skidding
Striped.By the way that above-mentioned cannula structure is arranged, on the one hand, so that the gripping stability of pencil is enhanced；On the other hand, with beginning to write
Bar is gradually cut short in use, periodically slightly imposes external force by user, casing is from bottom to top periodically along penholder
Displacement, is conducive to when penholder use to smaller length, manpower can not usually be held, and can act on and continue by the extension of casing
It uses, so that pencil is able to the use of maximum length, reduces waste, economize on resources.
As also a kind of preferred embodiment, as shown in fig. 6, the pencil of the utility model also can be used the second casing 8 to replace
First sleeve 7, second casing 8 the difference is that only that three of them outer surface is not provided with hole with aforementioned first sleeve 7,
But respectively there is an outside finger ring, respectively index finger finger ring 81, middle finger finger ring 82 in three outer surfaces of the second casing 8
With thumb finger ring 83.Wherein, the index finger cover of user enters in index finger finger ring 81, and middle finger is inserted in middle finger finger ring 82, and thumb is inserted in
In thumb finger ring 83, penholder or casing are handled by the fixing clamp of finger ring.Wherein, index finger finger ring 81 is parallel with middle finger finger ring 82
Or it is roughly parallel to the setting of pencil cross section, thumb finger ring 83 is vertical or to be approximately perpendicular to pencil cross section vertically arranged, above-mentioned
The entrance and force that can guarantee grasping person's finger section are set.By the way that above-mentioned cannula structure is arranged, especially by three finger rings
Structure designs the constraint, it can be achieved that the finger that holds a pen, and corrects bad posture, enables the children just to learn to write with correct
The posture that holds a pen realizes stable gripping.
Three sides of the non-equilateral triangle cross section pencil of the utility model can be indent camber line, as shown in Figure 7.Or
Three sides of person, the non-equilateral triangle cross section pencil of the utility model can be evagination camber line, as shown in Figure 8.Or
It is evagination camber line that three sides of the non-equilateral triangle cross section pencil of the utility model, which can be both sides, is on one side imploded arcs
Line；It can also be on one side evagination camber line using both sides as indent camber line, it is preferable that evagination camber line is set by third side 3, correspondingly,
Lateral surface where third side is outer convex globoidal, may be implemented to better contact with the hand tiger's jaw of user, as shown in Figure 9.
Rubber layer is provided with outside three sides of the non-equilateral triangle cross section pencil of the utility model.The rubber layer can play anti-skidding
Purpose, can be used for erasing pencil writing.
