the connecting strip is arranged at the lower side of the inside of the fixing piece; the right side of the connecting strip is provided with a first pin which is connected with a right side cavity of the fixing piece; a third pin is arranged in the connecting strip;
the resistance gas spring is arranged on the left side of the connecting strip, and the resistance gas spring is connected with the connecting strip through a second pin; the left side of the resistance gas spring is connected with the left side inside of the fixing piece;
the torsional spring is arranged in the fixing piece and on the upper side of the connecting strip, the right side of the torsional spring is contacted with the rotating head, the left side of the torsional spring is connected with the cavity wall, and the left end of the support handle is arranged in the torsional spring in a penetrating way;
as a further improvement of the utility model, a gland is arranged on the left side of the torsion spring, and the gland is connected with the cavity wall.
After the structure is adopted, the utility model has the beneficial effects that:
1. after the person at the meeting place opens the tablet, the person does not need to deliberately put back by hand when leaving the meeting place, and the person stands up the tablet to return automatically, so that a channel is reserved.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic structural view of the present utility model.
Reference numerals illustrate:
the rotary type writing board comprises a fixing piece 1, a rotary head 2, a supporting handle 3, a writing board 4, a resistance gas spring 5, a connecting strip 6, a first pin 7, a second pin 8, a third pin 9, a torsion spring 10 and a pressing cover 11.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Example 1:
referring to fig. 1, the embodiment includes:
the fixing piece 1 is connected with the armrest of the auditorium chair;
