Description

Adjustable appliance for holding pen

Technical field

The invention belongs to teach CAL appliance technology, and in particular to a kind of adjustable appliance for holding pen.

Background technology

At present, China A nearsighted person is a lot, and there are many what is formed from the school-days, incorrect sitting posture, holds a pen Posture can all allow student near-sighted too early.

In the market, to correct the pen holding posture of student, there are some appliance for holding pen of many manufacturer productions, basic structure shape Formula is the different sleeve of the material being enclosed on penholder, by being provided with corresponding limiting structure in cartridge exterior to ensure the appearance that holds a pen The accuracy of gesture, the appliance for holding pen structure of this kind of form is single, because each portion of the size of writing pen on the market is identical, appliance for holding pen It can not be used cooperatively well with various sizes of pen；Meanwhile appliance for holding pen external restraint structure is also configured to unique chi of fixation It is very little, it is impossible to well adapt to different size of palm, such as pupil and adult, palm it is of different sizes, using same type Number appliance for holding pen can not comfortably be write very much.

The content of the invention

It is an object of the invention to propose a kind of adjustable appliance for holding pen, solving can not be with different size existing for prior art Pen the problem of being used cooperatively and not adapting to different size of palm.

To achieve the above object, adjustable appliance for holding pen of the invention includes：

Internal jacket, the internal jacket are tubular structure, and outer wall is provided with external screw thread, and inwall matches somebody with somebody to merge with penholder clamps pen Bar；

The outer expansion set being enclosed in the internal jacket, the outer expansion set include the swollen head of spherical shell shape, and swollen head both ends are top splenium, institute Swollen head is stated using internal jacket axis as the multiple second deformation grooves of center line circumference uniform distribution；

And the regulation ring with the external screw thread cooperation of the internal jacket, two regulation rings are arranged on the two of outer expansion set Side, two regulation rings contact with the top splenium at the outer expansion set both ends respectively.

The inwall and penholder are specially with clamping penholder is merged：The internal jacket includes middle cylindric guide part And the clamping part of the taper positioned at guide part both ends；The clamping part is from close guide part one end to away from guide part one end chi Very little to taper into, the multiple first deformation grooves of clamping part circumference uniform distribution, the first deformation groove extends to guide part；Natural shape During state, the internal diameter of the clamping part small end of the internal jacket is less than the external diameter of penholder to be held.

When two regulation rings inwardly turn the outer expansion set of extruding and reach maximum compressibility, regulation ring and the first deformation groove weight The length of conjunction is more than zero.

It is 6mm during the internal diameter nature of the clamping part small end.

The internal jacket is integral type structure.

The first deformation groove includes four.

The outer expansion set is integral type structure.

The second deformation groove comprises at least four.

The adjustable appliance for holding pen is nylon material.

Beneficial effects of the present invention are：The adjustable appliance for holding pen of the present invention is that internal jacket and outside are rectified including internal fixed part Positive portion is outer expansion set；Outer expansion set is enclosed in internal jacket, is extruded outside by the turning for two regulation rings being threadedly coupled with internal jacket Expansion set, the outer multiple second deformation grooves of expansion set circumference uniform distribution, the regulation of outer expansion set external dimensions is realized, adapts to different size of hand The palm, is more beneficial for different size of palm and comfortably carries out correction writing；The internal jacket of the present invention is provided at both ends with clamping part, presss from both sides The portion of holding is provided with the first deformation groove, and the effect of the first deformation groove makes clamping part inside dimension diminish to clamp penholder, same operation Mode, the clamping force of penholder is more than when penholder is thicker penholder it is thinner when to the clamping force of penholder.

Embodiment

Embodiments of the present invention are described further below in conjunction with the accompanying drawings.

Referring to accompanying drawing 1- accompanying drawings 3, adjustable appliance for holding pen of the invention includes：

Internal jacket 1, the internal jacket 1 are tubular structure, and outer wall is provided with external screw thread, and inwall matches somebody with somebody to merge with penholder clamps pen Bar；

The outer expansion set 2 being enclosed in the internal jacket 1, the outer expansion set 2 include spherical shell shape swollen first 201, and swollen first 201 both ends are Top splenium 202, described swollen first 201 using the axis of internal jacket 1 as the multiple second deformation grooves 203 of center line circumference uniform distribution；

And the regulation ring 3 with the external screw thread cooperation of the internal jacket 1, two regulation rings 3 are arranged on outer expansion set 2 Both sides, top splenium 202 of two regulation rings 3 respectively with the outer both ends of expansion set 2 contact.

Referring to accompanying drawing 4, the inwall is specially with clamping penholder is merged with penholder：The internal jacket 1 includes middle circle The clamping part 102 of the guide part 101 of tubular and taper positioned at the both ends of guide part 101；The clamping part 102 is by close to guiding The one end of portion 101 tapers into away from one end size of guide part 101, the multiple first deformation grooves of the circumference uniform distribution of clamping part 102 103, clamping part 102 is divided and extends to guide part 101 for multiple lamellar bodies, the first deformation groove 103；It is described during nature The internal diameter of the small end of clamping part 102 of internal jacket 1 is less than the external diameter of penholder to be held.

When two regulation rings 3 inwardly turn the outer expansion set 2 of extruding and reach maximum compressibility, regulation ring 3 and first deformation The length that groove 103 overlaps is more than zero, plays a part of protection.

It is 6mm during the internal diameter nature of the small end of clamping part 102, the penholder that external diameter is 8-12mm can be clamped.

The internal jacket 1 is integral type structure.

The first deformation groove 103 includes four.

The outer expansion set 2 is integral type structure.

The second deformation groove 203 comprises at least four.

The adjustable appliance for holding pen is nylon material.

The adjustable appliance for holding pen of the present invention when in use, penholder is inserted into internal jacket 1, the external diameter of penholder is more than inner clip The internal diameter of the small end of the clamping part 102 at 1 both ends is covered, by the elastic force of multiple lamellar bodies of clamping part 102 to penholder after penholder insertion It is clamped, in limit range, the penholder of various outer diameter is clamped；Inwardly turning two regulation rings 3 extrudes outer expansion set 2, Outer expansion set 2 is deformed, realizes the regulation of external expansion set 2, changes the external dimensions of outer expansion set 2, adapts to the size of different palms, this The thickness of outer expansion set 2 in embodiment is processed as 1mm.Some materials can be suitably added on the premise of integral hardness is ensured to carry The elasticity of high outer expansion set 2.
