Example 1

As shown in fig. 1-3, the myopia prevention support comprises a first rod body 1 and a second rod body 2 which are rotationally connected end to end, a limiting rod 3 is arranged at the outer end of the second rod body, and the limiting rod and the second rod body are arranged vertically. The first rod body and the second rod body jointly form an adjusting rod of the bracket; the adjusting rod is supported by a steel fixing seat 4, and a locking part used for fixing the adjusting rod at the position beside the table is arranged on the fixing seat.

The steel fixing seat 4 comprises a top plate 4.1, the rear end of the top plate is fixedly connected with the top end of a side plate 4.2, the bottom end of the side plate is fixedly connected with a bottom plate 4.3, and the top end of the top plate is fixedly connected with a vertical plate 4.4; the retaining member includes first retaining member 5 and second retaining member 6, and first retaining member is located on the bottom plate, and the second retaining member is located on vertical board. The vertical plate is welded and fixed in the middle of the top plate. The first locking member is a bolt threaded with the bottom wall. The bottom of the first rod body 1 and the vertical plate 4.4 are locked through a second locking piece 6. The second locking piece comprises a pin shaft, and the pin shaft penetrates through the bottom of the first rod body and the vertical plate and then is locked through the bolt.

And handle rods which are convenient to screw are arranged at the end parts of the pin shafts of the first locking piece and the second locking piece.

The first rod body 1 and the second rod body 2 are both wood rod bodies; the top of the first body of rod rotates with the one end of the second body of rod and links to each other, links firmly at the other end of the second body of rod gag lever post 3, gag lever post are the cylinder gag lever post, and the cylinder gag lever post can be plastics or silica gel cylinder gag lever post.

An auxiliary lug 7 is also arranged on one side of the end part of the second rod body; the limiting rod is fixedly connected with the top end of the second rod body and the auxiliary lug. The arrangement of the auxiliary lug ensures the stability of the connection of the second rod body and the limiting rod. The auxiliary lug is fixedly connected with the second rod body through a screw.

During the use, aim at the desktop rear side with the opening of steel fixing base 4 and overlap, twist the first retaining member 5 on the bottom plate 4.3, make the top of first retaining member contact gradually and support the bottom surface of desktop rear side outer edge tightly, fixed this support. The first rod body 1 is properly rotated to be vertical or inclined towards the front side of a desktop, then the second rod body 2 is rotated to enable the front side of the limiting rod 3 to be at a proper height position of the head of a teenager during writing, after the teenager sits up, proper adjustment is carried out, the front side of the limiting rod is enabled to be in contact with the forehead of the teenager, therefore, in the writing process, the effects of reminding and standardizing the height of eyes from the desktop during writing are achieved, in the using process, the head of the teenager cannot be bound and interfered, the sight line of the eyes and the angle of a book are not limited, and the auxiliary effect of preventing myopia of the teenager and standardizing the low head height during writing is better. When not using, the second body of rod 2 rotates downwards, makes it be close first body of rod 1, accomodates in the desktop rear side under both vertical states, need not to dismantle, does not influence the normal use of desktop.

Example 2

As shown in fig. 4-5, the myopia prevention bracket is the same as the myopia prevention bracket of embodiment 1, except that a horizontal through groove 8 is further formed in the lower portion of the front side of the first rod body, and the horizontal through groove is matched with the limiting rod. The inner diameter of the horizontal through groove is not less than the outer diameter of the limiting rod. When the second rod body rotates downwards to the limiting rod to enter the horizontal through groove, the second rod body is flush with the first rod body. So set up, can be after accomodating, make gag lever post 3 directly enter into the logical groove 8 of level along with the rotation of the second body of rod, at this moment, first, the second body of rod front side flushes on vertical direction basically, pleasing to the eye, save space, regular.

The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.
