Preferably, a fixing device is composed of the balancing weight 11, the rotating shaft 16, the movable rod 14, the suction cup 15 and the rotating groove 13, the curtain 10 still can shake back and forth under the condition of the balancing weight 11 during teaching at present, so that the following students can not see clearly, in the fixing device, two light sliders with the size corresponding to that of the suction cup 15 are installed at the corresponding positions on the two side walls (if the smooth suction cup on the wall surface can suck the light sliders, the light sliders are not needed to be installed) after the curtain 10 is put down, then after the curtain 10 drives the balancing weight 11 to expand downwards from the curtain collector 3, a user firstly holds the movable rod 14 to drive the suction cup 15 to rotate upwards at the rotating groove 13 through the rotating shaft 16, so that the movable rod 14 and the balancing weight 11 are in a straight shape, then holds the suction cup 15 to rotate at the movable rod 14 through the rotating ball at one side of the movable rod 14, so that the suction cup 15 is right opposite to the smooth block, reuse power presses down sucking disc 15, make 15 laminating smooth sliders of sucking disc, after 15 corresponding smooth sliders on the wall of all laminating of sucking disc of both sides, curtain 10 will be because of the fixed condition of rocking around can no longer producing of both sides sucking disc 15, sucking disc 15 is used many times simultaneously, make can take off sucking disc 15 from smooth piece after the user uses rotatory in the original place, drive curtain 10 again and drive balancing weight 11 to packing up, thereby the person of facilitating the use fixes sucking disc 15 drive balancing weight 11 and wall many times, sucking disc 15's simple manufacture makes its use cost also low simultaneously, thereby improved the utility model discloses a convenience.

The working principle is as follows:

firstly, when a user fixes the instrument holder 4 and the projector 2, the connecting rod 405 at the position of the handheld instrument holder 4 is used for driving the inserting column 402 to be placed in the groove at the top of the projector 2, when the bottom end of the inserting column 402 is attached to the bottom of the groove, the user presses the switch 401 to enable the inserting column 402 to expand the extending column 403 inside towards two sides, meanwhile, the projector 2 also has a placing groove with a corresponding size and shape at a corresponding position, when the extending column 403 is placed, the instrument holder 4 clamps the projector 2, wherein because the groove inside the projector 2 is completely attached to the inserting column 402 and the extending column 403 of the instrument holder 4, the left-right moving condition cannot be generated when the projector 2 and the instrument holder 4 are fixed, and when the projector 2 and the instrument holder 4 are placed, the user puts a screw through the placing hole 12 at the fixing groove 404 and then rotationally fixes the screw at the fixing groove 404, the projector 2 and the instrument frame 4 are fixed twice, so that the projector 2 and the instrument frame 4 are fixed more, meanwhile, the instrument frame 4 and the screws form a clamping plate state to clamp and fix the top of the projector 2, and when the screws are loosened, the extending columns 403 can bear the top of the projector 2, so that the projector 2 cannot drop downwards when the screws are loosened;

then, two rows of placing holes 12 are arranged at the top of the projector 2, six placing holes are arranged, the placing holes 12 are used together with the fixing groove 404 of the instrument frame 4, a user firstly places a hand-held screw at the position of the fixing groove 404 after passing through the placing holes 12, and then fixes the hand-held screw in the fixing groove 404 by rotating the hand-held screw in the fixing groove 404, so that the connection between the projector 2 and the instrument frame 4 is more fixed due to the multiple placing holes 12, and the fixing performance of the utility model is improved;

then, a telescopic column 5 capable of being telescopic is arranged in the middle of the instrument frame 4, when a user fixes the projector 2 on the instrument frame 4 and installs the instrument frame 4 on a ceiling, and the user feels that the projector 2 is too high, the user can drive the projector 2 to descend and extend upwards together by controlling the bottom of the remote controller instrument frame 4 of the projector 2, so that the user can conveniently and slowly adjust the placing height of the projector 2, and the adjustability of the utility model is improved;

next, when the user uses the projector 2 for teaching, the driving post 18 is opened together with the opening of the projector 2, and when the driving post 18 is opened, the driving post 18 drives the mirror cover 9 to move to the other side along the sliding groove 17, and when the projector 2 is closed, the driving post 18 drives the mirror cover 9 to move to the lens 8 from one side along the sliding groove 17, wherein the driving posts 18 are arranged at two ends of the mirror cover 9, and the driving posts 18 at the two ends can play a role in stabilizing the movement of the mirror cover 9, and meanwhile, the mirror cover 9 is arranged on the lens 8, so that the problem condition that dust is accumulated on the lens 8 when the projector 2 is not used to cause projection can be prevented;

finally, because the curtain 10 still can shake the situation before and after having the clump weight 11 in the teaching at present, the student below can't see clearly, but in this fixing device, will install two smooth sliders with the corresponding size of the sucking disc 15 on the corresponding position of the two side walls after the curtain 10 is put down (if the smooth sucking disc of the wall can suck and just need not install the smooth slider), and then after the curtain 10 drives the clump weight 11 to expand from the place of receiving the curtain ware 3 downwards, the user will hold the movable rod 14 and drive the sucking disc 15 to rotate upwards at the rotary groove 13 through the rotating shaft 16 first, make the movable rod 14 and the clump weight 11 become a straight line, then hold the sucking disc 15 and rotate at the movable rod 14 through the rotary ball on one side of the movable rod 14, make the sucking disc 15 face the smooth block, then press the sucking disc 15 with the power, make the sucking disc 15 stick to the smooth slider, after the sucking discs 15 on both sides stick to the corresponding smooth slider on the wall, curtain 10 will be because of the fixed condition that rocks around can no longer producing of both sides sucking disc 15, sucking disc 15 is used many times simultaneously, makes user use back can take off sucking disc 15 from smooth piece rotation in the original place, drives curtain 10 again to packing up balancing weight 11 to, thereby the person of facilitating the use is fixed sucking disc 15 drive balancing weight 11 and wall many times, and sucking disc 15's simple manufacture makes its use cost also low simultaneously, thereby has improved the utility model discloses a convenience, this is this kind of thinks the theory of projection arrangement's that political affairs education used theory.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
