In order to realize that the paving mechanism 6 is moved to the position hooked by the elastic moving mechanism 4 after the current film is watched, and only the walking block 61 is moved, the operation is convenient, so that the following design is made: second inserted bar 43 is connected with installation pole 71, installation pole 71 is perpendicular with second inserted bar 43, installation pole 71 is installed and is had the extrusion wheel 72 that can rotate, extrusion wheel 72 can be used for with three hornblocks 73, three hornblocks 73 most advanced are located three hornblocks 73 wide end top, three hornblocks 73 upper inclined planes are used for tangent with extrusion wheel 72, the contained angle is the acute angle between inclined plane and the vertical direction on the three hornblocks 73, three hornblocks 73 are fixed to connecting foot 62, set up on the link 63 and supply second inserted bar 43 male second jack, the second jack is enough big, make second inserted bar 43 insert in the link 63 after the link 63 can move on vertical direction second inserted bar 43 relatively.

The working principle of the embodiment is as follows:

before cutting, the second inserted bar 43 in the elastic moving mechanism 4 hooks the hanging ring 63 of the paving mechanism 6 to keep the paving mechanism 6 at the top of the display surface, the limit pin 51 is inserted into the jack formed in the moving block 41 under the elastic force of the third spring 52, the elastic positioning mechanism 5 keeps the elastic moving mechanism 4 hooking the paving mechanism 6 before cutting, at the moment, a distance is reserved between the first inserted bar 42 and the elastic cutting mechanism 3, and when a film is inserted into the slot, the film can be inserted between the first inserted bar 42 and the cutting knife 31.

When a film needs to be placed, firstly, the film passes through the gap between the walking block 61 and the display surface and then is inserted into the slot, and then the film passes through the slot and then is inserted between the first inserting rod 42 and the cutting knife 31; then, the pressing rod 33 is pressed, so that the cutting knife 31 moves towards the first inserting rod 42, the moving block 41 and the second inserting rod 43 move towards the direction away from the elastic cutting mechanism 3, finally, the inner wall of the display stand 1 supports the cutting knife 31 through the second inserting rod 43 and the moving block 41, holes are formed in the film by the cutting knife 31, and the elastic potential energy of the second spring 44 is increased; then, the pressing rod 33 is loosened, the cutting knife 31 is far away from the first inserting rod 42 under the elastic force of the first spring 34, meanwhile, the first inserting rod 42 is inserted into a through hole formed in the film under the elastic force of the second spring 44, the moving block 41 is high in speed due to the elastic force of the second spring 44 and free of obstruction, therefore, the limiting pin 51 can be quickly crossed by the limiting hole, the first inserting rod 42 is inserted into the through hole in the film, the second inserting rod 43 is separated from the hanging ring 63, the walking block 61 moves to the bottom of the film from the top of the film under the self-gravity condition of the walking block 61, the film is laid on the display surface by the walking block 61, and placement is achieved.

After the film is viewed, the walking block 61 is manually pushed, so that the walking block 61 moves upwards, the second insertion hole on the hanging ring 63 is aligned with the second insertion rod 43, in order to move the moving block 41, the walking block 61 is pushed continuously, the triangular block 73 presses the moving block 41 to move through the pressing wheel 72, thereby, the pressing moving block 41 is moved in a direction away from the elastic cutting mechanism 3, so that the second insertion rod 43 is inserted into the second insertion hole, since the second spring 44 has a tendency to block the moving block 41 from moving, the moving block 41 moves slowly, and when the stopper pin 51 is aligned with the stopper hole, the limit pin 51 is inserted into the limit hole under the elastic force of the third spring 52 to realize the limit, so that the state that the second insertion rod 43 is inserted into the second insertion hole is maintained, the walking block 61 is loosened, the walking block 61 can descend for a certain distance, but the hanging ring 63 cannot be separated from the second insertion rod 43. The restoration to the initial state is facilitated.

The design idea of this embodiment is as follows: firstly, in order to realize that the top of the film can be hooked after the film is cut, an elastic cutting mechanism 3 and an elastic moving mechanism 4 are designed; then, in order to release the paving mechanism 6 after the top of the film is hooked, the paving mechanism 6 is designed to be hooked by the elastic moving mechanism 4; then, in order to avoid the elastic moving mechanism 4 from influencing the insertion of the film into the card slot and being located in front of the first insertion rod 42 and the cutting knife 31, the limiting mechanism 86 is designed, so that the first insertion rod 42 is kept at the middle position, the paving mechanism 6 can be hooked, and the first insertion rod 42 can be prevented from obstructing the insertion of the film; finally, in order to realize that the walking block 61 can be positioned to the top of the display surface only by pushing the walking block 61, the mounting rod 71, the extrusion wheel 72 and the triangular block 73 are designed, and the operation is convenient.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
