In this embodiment, the pulling plate 1974 is pulled downwards, so that the pulling plate 1974 drives the sliding block 1973 to slide in the sliding groove 1972, and the C-shaped plate 196 is limited by the connection of the L-shaped connecting plate 1977, therefore, when the L-shaped connecting plate 1977 moves along with the sliding block 1973, the C-shaped plate 196 also synchronously displaces in the square groove 195, the pulling plate 1974 drives the spring 1976 to displace, the spring 1976 extends, the vertical rod 1975 and the second limit groove 1971 exist, the travelling path of the spring 1976 can be limited, the regulating structure 197 is arranged on two sides of the rotating rod 193, and the position of the C-shaped plate 196 can be regulated, so that a user is assisted to adhere a poster in the C-shaped plate 196, and the initial state of the spring 1976 is in an extending state, therefore, once the position limitation of the pulling plate 1974 is released, the spring 1976 drives the assembly to reset, so that the top of the C-shaped plate 196 can contact the inner wall of the square groove 195, the sliding groove 1972, the sliding groove 1973 and the vertical rod 1975 exist, and the pulling plate 1975 can all have auxiliary effects, so that the pulling plate 1974 can move in a straight line in the second limit groove 1971.
Working principle:
when the device is used, as shown in fig. 1-7, firstly, the poking plate 1974 is poked downwards, the poking plate 1974 drives the sliding block 1973 to slide in the sliding groove 1972, and the C-shaped plate 196 is limited by the connection of the L-shaped connecting plate 1977, therefore, when the L-shaped connecting plate 1977 moves along with the sliding block 1973, the C-shaped plate 196 synchronously displaces in the square groove 195, the poking plate 1974 drives the spring 1976 to displace, the spring 1976 extends, the upright rod 1975 and the second limiting groove 1971 can limit the travelling path of the spring 1976 to make the spring 1976 move in a straight line, then the poster is adhered in the C-shaped plate 196, after the C-shaped plate 196 is loosened, the C-shaped plate 196 drives the regulating structure 197 to reset, the poster extends to the outside of the rotating rod 193 through the gap between the C-shaped plate 196 and the rotating rod 193, the rotating rod 193 is movably mounted on the circular shaft 192 on the inner side of the supporting frame 11 through the groove 194, after the position of the rotating rod 193 is mounted in the support frame 11, one of the circular shafts 192 is fixedly connected with the output shaft of the servo motor 16, so that when the servo motor 16 rotates, the rotating rod 193 limited by the position of the circular shaft 192 also rotates synchronously, at the moment, through the position gap between the C-shaped plate 196 and the rotating rod 193, the poster extending out of the rotating rod 193 is wound outside the rotating rod 193, the other end of the poster is mounted in the clamping plate 178, the outer surface of the clamping plate 178 is in a tooth-shaped design, the clamping plate 178 is beneficial to clamping the poster, after the poster is placed in the clamping plate 178, the arc-shaped side edge 174 arranged on one side edge of the mounting base 173 is flush with the rotating shaft 175, therefore, the rotating shaft 175 can drive the clamping plate 178 above the rotating shaft to shift in position, so that the two clamping plates 178 are meshed, and finally, in a limiting mode of connecting the threaded holes 176 through the threaded columns 177, the two clamping plates 178 are fixed in position, the fixing structure 17 is supported and limited in position by means of the limiting columns 143 movably clamping the limiting holes 142 and the first limiting grooves 13, the semicircular angle 172 arranged on one side edge of the weight plate 171 can be contacted with the start-stop button 20, so that the operation of the servo motor 16 is stopped, once the weight plate 171 contacts with the start-stop button 20 at the bottom end of the supporting frame 11, the motor stops running, and the corresponding rolling structure 19 stops rolling the poster, so that the poster can maintain the unfolded or folded form.
The present invention is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present invention without departing from the technical content of the present invention still belong to the protection scope of the technical solution of the present invention.
