Swollen head is stated using internal jacket axis as the multiple second deformation slots of middle line circumference uniform distribution；
And the adjusting ring with the external screw thread cooperation of the internal jacket, two adjusting rings are arranged in the two of outer expansion set
Side, two adjusting rings are contacted with the top splenium at the outer expansion set both ends respectively.
The inner wall, which matches to merge with penholder, clamps penholder specifically: the internal jacket includes intermediate cylindric guide part
And the clamping part of the cone cell positioned at guide part both ends；The clamping part is from close guide part one end to far from guide part one end ruler
Very little to gradually become smaller, the multiple first deformation slots of clamping part circumference uniform distribution, the first deformation slot extends to guide part；Natural shape
When state, the internal diameter of the clamping part small end of the internal jacket is less than the outer diameter of penholder to be held.
It is turned in two adjustings circumferential direction when squeezing outer expansion set and reaching maximum compressibility, adjusting ring and the first deformation slot weight
The length of conjunction is greater than zero.
It is 6mm when the internal diameter nature of the clamping part small end.
The internal jacket is an integral structure.
The first deformation slot includes four.
The outer expansion set is an integral structure.
The second deformation slot includes at least four.
The adjustable appliance for holding pen is nylon material.
The utility model has the following beneficial effects: the adjustable appliance for holding pen of the utility model includes internal fixed part i.e. internal jacket
It is outer expansion set with external correction unit；Outer expansion set covers in internal jacket, adjusts twisting for rings by two be threadedly coupled with internal jacket
Dynamic to squeeze outer expansion set, the outer multiple second deformation slots of expansion set circumference uniform distribution realize the adjusting of outer expansion set external dimensions, adapt to different big
Small palm is more advantageous to different size of palm and comfortably carries out correction writing；The internal jacket both ends of the utility model are arranged
There is a clamping part, clamping part is provided with the first deformation slot, and the effect of the first deformation slot makes clamping part inside dimension become smaller to clamp penholder,
Same mode of operation, when penholder is thicker to the clamping force of penholder be greater than penholder it is thinner when to the clamping force of penholder.

Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Referring to attached drawing 1- attached drawing 3, the adjustable appliance for holding pen of the utility model includes:
Internal jacket 1, the internal jacket 1 are tubular structure, and outer wall is provided with external screw thread, and inner wall, which matches to merge with penholder, clamps pen
Bar；
The outer expansion set 2 in the internal jacket 1 is covered, the outer expansion set 2 includes the swollen head 201 of spherical shell shape, and swollen 201 both ends of head are
Top splenium 202, the swollen head 201 is using 1 axis of internal jacket as the multiple second deformation slots 203 of middle line circumference uniform distribution；
And outer expansion set 2 is arranged in the adjusting ring 3 with the external screw thread cooperation of the internal jacket 1, two adjusting rings 3
Two sides, two adjusting rings 3 are contacted with the top splenium 202 at outer 2 both ends of expansion set respectively.
Referring to attached drawing 4, the inner wall, which matches to merge with penholder, clamps penholder specifically: the internal jacket 1 includes intermediate circle
