The specific embodiment
Below in conjunction with example, the utility model is described in detail.
The utility model provides an a kind of myopia prevention joint device, its structural representation such as Fig. 1 and shown in Figure 5.
A myopia prevention joint device as Figure 1-3, a joint device is followed successively by penholder, pen holding region and clamp area from top to bottom along its axis direction, and the internal diameter of penholder, pen holding region and clamp area is greater than the external diameter of pencil.Pen holding region is provided with catch 1, and pen holding region and clamp area junction are provided with stick shift 2, and clamp area is provided with intermediate plate 4 and is used in conjunction with it the retainer 3 of locking pencil.Pen holding region is axially drum type along it, and pen holding region is provided with arc groove, and drum type structure and groove make the student more comfortable when holding a pen.The number of groove 5 is 3, and the groove 5 adjacent with catch 1 is symmetrical arranged along catch 1, is the place that holds a pen of thumb and forefinger, and the groove 5 relative with catch 1 is the place that holds a pen of middle finger.
Fig. 4 is the retainer structural representation, and retainer 3 is the cap shape, and two ends connect, and pencil can pass retainer 3, and the effect of retainer 3 is that pencil is played fixation.
The plane at catch 1 place is vertical with horizontal plane, catch 1 purpose is set for stoping the student when holding a pen, thumb contacts with forefinger or the wrong pen holding posture such as intersects; The plane at stick shift 2 places is parallel with horizontal plane, and the purpose that arranges of stick shift 2 is the height that hold a pen that guarantee the student, avoid due to the student hold a pen highly too low, and writing of causing sight line is lived in stick shift and torticollis is write or closely write.The normal direction of catch 1 is parallel with the axis direction of a described joint device.
Penholder can be overall structure or multi-section type structure.When penholder was overall structure, penholder was that diameter is cylindric uniformly, the top of penholder, and namely penholder is hatch frame away from an end of pen holding region; When penholder was the multi-section type structure, the top of penholder was enclosed construction, as shown in Figure 5 and Figure 6, penholder is three-section type, comprises A section, B section and C section, and A section, B section and C section are linked in sequence, the A section of penholder more carefully locates, and can assist the shorter pencil stub of length to be fixed on clamp area.
Accompanying drawing 7-12 is that penholder is the partial schematic diagram of a three-section type myopia prevention joint device.A three-section type myopia prevention joint device easy accessibility.
A myopia prevention joint device of the present utility model, be provided with catch 1 and stick shift 2, catch 1 can be when the pupil holds a pen, stop its thumb contact with forefinger or intersect, the height that holds a pen simultaneously keeps in the reasonable scope, guarantees student nib and the rational angle of desktop maintenance in writing process, place and the rational height of desktop maintenance hold a pen, the pupil can see nib clearly, thereby keeps correct writing posture, prevents bathomorphic formation; And the groove 5 that the drum type structure of pen holding region and pen holding region arrange, auxiliary catch 1 keeps pupil's writing posture together.
A joint device, by the setting of intermediate plate 4 and retainer 3, can reuse shorter pencil stub, and lower to the length requirement of pencil stub than general pencil extender, can take full advantage of shorter pencil stub, reaches the purpose of energy savings.
The penholder of a joint device can be overall structure and multi-section type structure, and various informativeization, can be suitable for different consumers.
According to specific exemplary embodiment, the utility model is described herein.To carry out suitable replacement or revise will be apparent not breaking away under scope of the present utility model to one skilled in the art.Exemplary embodiment is only illustrative, rather than to the restriction of scope of the present utility model, scope of the present utility model is by appended claim definition.
