Stricture of vagina set, described lower semisphere are provided with circular hole, and described supporting linkage passes through described circular hole, described episphere connection lifting
Device, has positioner between described episphere and described interior hollow ball.
A kind of described electronic tutor based on radio communication, is provided with one group of jack at the top of described episphere,
Described positioner includes flexibly positioned inserted link, and the top of described interior hollow ball connects described flexibly positioned inserted link, institute
The jack positioning described in flexibly positioned inserted link insertion described in when the interior hollow ball stated is rotated；Described computer connection teaching
Table, described projection screen connection spool, described spool connection classroom body of wall.
A kind of described electronic tutor based on radio communication, described lowering or hoisting gear include top board, described top
Plate is connected on the ceiling of classroom, and described top board connects left connection board and right connection board, described left connection board and the described right side
Connected by transverse axis between connecting plate, described transverse axis connection upper sprocket wheel, described upper sprocket wheel connection chain, described chain connect
Lower sprocket is connect, described lower sprocket connection connecting plate, described connecting plate connect L-shaped axle, and described L-shaped axle connects described
Episphere.
Beneficial effect：
1. this utility model is adopted supporting linkage, circular hole make interior hollow ball rotation side in the outer hollow ball
Just, it is very convenient during the projector adjustment angle of drive.
The inner screw sheath that this utility model is adopted is used cooperatively with external thread sleeve, can be made between episphere and lower semisphere
It is easy to connect, it is also convenient for when loading interior hollow ball, it is good using flexible, effect.
The flexibly positioned inserted link that this utility model is adopted is used cooperatively with jack, can give interior hollow ball and outer space bulbus cordis it
Between accurately positioned when mutually rotating, adjustment projector is convenient, flexibly, and using effect is good.
The top board of this utility model employing, left connection board, right connection board, transverse axis, upper sprocket wheel, chain, lower sprocket, connecting plate
Use cooperatively, i.e., projector can be firmly fixed on the ceiling of classroom, the height for adjusting projector is also convenient for, convenient and meter
Calculation machine, projection screen are good with the use of effect.
