Upper end.
Preferentially, the telescoping mechanism includes upper expansion link, middle expansion link, lower expansion link, and the lower expansion link is vertically solid
Surely it is arranged on the front side wall of the table tripe, the cross section of the middle expansion link is " H " type, and the middle expansion link is advancing slip in including
Pole, connecting portion and in after litter, in described preceding litter by the connecting portion be fixedly connected it is described in after litter, it is described lower flexible
Rod set set and be slidably connected it is described in after litter, the upper expansion link be arranged and be slidably connected it is described in preceding litter.
Preferentially, including for prevent it is described in after litter depart from the first stop screw of the lower expansion link and for preventing
Preceding litter departs from the second stop screw of the upper expansion link in only described, and first stop screw is vertically and fixedly arranged at institute
State on expansion link rear wall bottom, second stop screw is vertically and fixedly arranged at the lower expansion link front side wall top
On, in described on preceding litter front side wall, it is described in after open up respectively on litter rear wall and coordinate first stop screw, described
The T-slot of second stop screw.
Preferentially, holding tank is opened up in the table tripe, the holding tank includes several books holding tanks.
Preferentially, the table leg includes upper table leg and lower table leg, and the upper table leg is arranged and the lower table leg that is slidably connected.
Preferentially, the table includes left table and right board, and the left table, the right board are respectively articulated with the table
The left side wall of tripe upper surface and the right side wall of the table tripe upper surface.
The beneficial effect that the present invention is reached：
When indoor light is dim, and student is sitting in corner or any one generation of the reflective three kinds of situations of metope, student can be from table
Extract magnifying glass on front side of tripe out, and reach regulation angle clearly to watch the purpose of blackboard, when without using this by rotating magnifying glass
The present apparatus that need to only be retracted during invention can not take up space, easy to use；The T-slot opened up on middle expansion link coordinates stop screw to keep away
Exempt to depart between upper expansion link and middle expansion link, it is easy to use；
User is vertically placed on books in books holding tank, the side wall being encapsulated upward, one mesh when finding books
So, the efficiency by book is improved, saves the time；The Breadth Maximum of general book is 20cm, and the height of holding tank is more than 20cm
Allow the invention to accommodate all books, it is practical；Present invention, which receives the height user of groove, need to only open left table
Or right board can take books, taken without bending over, it is easy to use.
