Convenient regulation, and existing support needs to disassemble that student could be facilitated to operate other things when need not use, and needs to make
With when on desk, using relatively complicated.
The content of the invention
In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of myopia for student of universal adjustment
Support.
The myopia prevention stand for student of the universal adjustment of the utility model, it includes pin 1, inserted link 1-1, univesal wheelwork
2nd, the first fastening bolt 3, the second fastening bolt 4, lift adjustment bar 5, fastening screw 6, U-shaped card seat 7, fixed Pressing fastener 6-1, set
Intert the inserted link 1-1 for being provided with the bottom of pin 1 in the fastening bolt 9 of cylinder 8 and the 3rd, the univesal wheelwork 2 that two are correspondingly arranged,
And inserted link 1-1 is fixed by first fastening bolt 3 in the outside of univesal wheelwork 2 with univesal wheelwork 2, univesal wheelwork
2 inner side is provided with inserting hole, and the top of lift adjustment bar 5 is interspersed in the inserting hole of the inner side of univesal wheelwork 2, and is passed through
Second fastening bolt 4 is fixed with univesal wheelwork 2, and the bottom of lift adjustment bar 5 is connected with sleeve 8, and is provided with sleeve 8
3rd fastening bolt 9, the inner side of sleeve 8, which is provided with to intert on U-shaped card seat 7, U-shaped card seat 7, is provided with fastening screw 6, fastens
The bottom of screw rod 6 is provided with fixed Pressing fastener 6-1.
Preferably, the outside of described pin 1 is coated with one layer of protective case 1-3.
The beneficial effects of the utility model：The drawbacks of it can overcome prior art, reasonable in design is novel, this near-sighted frame
Can not only be adjusted in height, can also elastic adjustment longitudinal separation, can be adjusted according to the different height ages, keep off
Bar can also arbitrarily adjust angle, be also applied for the desk of various concaves, can also be by this when need not use
Near-sighted frame rotates to lower section, accepts, does not influence child to be had lunch on desk, nor affects on child's spring in the desk morning
Not, therefore using more convenient.
