Fitting, auxiliary 2662 left end of band of gas is mounted on the right side of airtight disk 2661 by way of insertion, inside the airtight disk 2661
Gas is suppressed if being filled with, elastic cuff 2664 can push blade 2663 and prop up hidden tie rod 2616, the spacer block of a protuberance is formed,
Enable 2616, hidden tie rod short-range traction is needed just to achieve the effect that beyond its hauling distance.
Wherein, the auxiliary band 2662 of the gas includes left side locking plate 26621, conduit 26622, gas band 26623, button hole 26624, the right side
Side chain folder 26625, the left side locking plate 26621 is fixed together with 26623 left end of gas band, 26623 right end of gas band
It is fixed together with right side locker 26625, the button hole 26624 is integrated with right side locker 26625, described to lead
26622 right end of pipe is mounted on locking plate 26621 inside in left side by way of insertion and is fixedly connected on one with 26623 left end of gas band
It rising, the gas band 26623 is in opposing seal state, since it uses silica type material to be made, at which when conventional sense,
, shaped like rugby and internal gassy, side wall has preferable elasticity for it, when by button hole 26624 by strong pull,
Gas band 26623 can be by axial elongation, and inner space becomes smaller, and is discharged so that gas be made to be suppressed via side.
Wherein, the regulation diagram plate 24 includes stablizing bar 241, side axle ring 242, folded item 243, sliding support external member 244, regulation
Plate 245, diagram disk 246,241 bottom end of stablizing bar is fixedly connected on 244 top of sliding support external member by the way of electric welding, described
244 bottom end of sliding support external member is fixedly connected on diagram 246 top of disk by the way of electric welding, and 246 top of diagram disk passes through tune
Control plate 245 is fixed together with 241 bottom end of stablizing bar, and the folded item 243 sets there are two altogether and is fixedly mounted on side axle ring
About 242 two sides, the side axle ring 242 is by folding the corral range on the adjustable diagram disk 246 of item 243, due to not jljl
Size, the length of product have differences, can be adjusted by side axle ring 242 and sliding support external member 244 when placing,
When carrying out dismantling explanation to article, as long as the camera of projection can be equal inside the corral that side axle ring 242 is covered
Focusing distance under the conditions of, guarantee the clarity of image.
The specifically used mode and effect of the present embodiment:
In the present invention, during electronic commerce teaching, in material object to be placed on to diagram disk 246, pass through the material object
Size, with the hands pulls 242 lateral magnification of side axle ring or is contracted to and meet the full size, passes through the length of the material object, court
Diagram disk 246 is pulled to outside, the length of 244 pairs of sliding support external member connect with stablizing bar 241 diagram disks 246 is enabled to be extended,
Angular adjustment is focused to the flexible camera lens of multi-angle 22 after the completion of placement, shows that device 2 is main with diagram meet due in kind
Glove position is set to the back of sheath body 5 and there are multiple regulations diagram plates 24 can disposably place institute in single curricula
The teaching object being related to is embedded in corresponding to corresponding placement and behind material object when lecturer imparts knowledge to students by that will inhale axis 3 by force
After determining ring 269, suction is set piece 267 and is returned by the strong attraction for inhaling axis 3, to towards upper-end bent and be in contact with it, is generating shape
Docking block 2614 by hidden tie rod 2616 while change has certain tractive force, and getting rid of for its transience can be enabled to draw item 2613 again
Constraint, and the magnetic block 268 in 264 side of saddle enters under the linkage for pushing away item 262 and draws and be in contact with it in frame 265, and
It enables and draws the whole local attraction's power enhancing of frame 265, the situation of gravitation unevenness can attract movable changer lever 21 to draw frame 265 enterprising
Row sliding, when it, which is rubbed into target, connects block 2614, whether from top to bottom or from lower to upper, first unidirectional limit at the time of contact
Handle 2615 can be received unidirectionally and be pressed, and second can directly be stopped, so that Dock With Precision Position is realized, in movable changer lever 21
Back is equipped with contact corresponding with connector 23, and image can be transmitted by contact point and be shown in projection screen 1 after Dock With Precision Position
On.
The embodiment of the present invention is given for the purpose of illustration and description, and is not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
Selecting and describe embodiment is and to make those skilled in the art to more preferably illustrate the principle of the present invention and practical application
