The chute 602 is opened on the front and rear sides of the middle part of the cross bar 601. One end of the cross bar 601 is rotatably connected to the left and right sides of the connecting frame 5. A long tail clip is arranged at the front part of the front slide block 603. The reel assembly 604 includes a micro motor 6041, a connecting plate 6042, a reel 6043 and a cable 6044. The middle part of the reel 6043 is rotatably connected to the opposite sides of the slide block 603. The micro motor 6041 is installed at the rear side of the connecting plate 6042. The connecting plate 6042 is installed at the rear side of the rear slide block 603. The output end of the micro motor 6041 penetrates through the connecting plate 6042 and is fixedly connected to the middle part of the reel 6043. The upper end of the cable 6044 is wound around the middle part of the reel 6043. The lower end of the cable 6044 is connected to a long tail clip. A counterweight 6045 is arranged at the lower end of the cable 6044.

[0023] Specifically, by pushing the retracting assembly 604, the slider 603 moves left and right inside the sliding groove 602, thereby adjusting the distance between the two retracting assemblies 604 to adapt to model drawings of different lengths. The micro motor 6041 is driven to wind or release the cable 6044 through the winding roller 6043, thereby adjusting the distance between the upper and lower long tail clips of the cable 6044, and further being applicable to model drawings of different widths.

[0024] In this embodiment, the lifting mechanism 1 includes a motor box 101, a reduction motor 102, a limit shell 103, a lifting rod 104, and a threaded rod 105. The lower end of the threaded rod 105 is rotatably connected to the outer top wall of the motor box 101. The outer circumference of the threaded rod 105 is threadedly connected to the middle of the lifting rod 104. The outer circumference of the lifting rod 104 is slidably connected inside the limit shell 103. The lower part of the limit shell 103 is installed on the upper part of the motor box 101. The outer circumference of the reduction motor 102 is installed on the inner bottom wall of the motor box 101.

[0025] Specifically, the limit shell 103 restricts the lifting rod 104 to prevent the lifting rod 104 from rotating. The reduction motor 102 is driven to rotate the threaded rod 105, and then the lifting rod 104 drives the hanging mechanism 6 to lift and lower, so that the display height of the model drawing can be adjusted. The cross bar 601 is unfolded and kept horizontal, then the lower part of the support rod 401 is aligned with the end of the support seat 402, and finally the pin shaft 403 is inserted into the holes of the two, thereby fixing the support rod 401 and the support seat 402, so that the support rod 401 supports the cross bar 601. At the same time, the pin shaft 403 can be removed when not in use, making the cross bar 601 parallel to the lifting mechanism 1, thereby completely reducing the volume of the device and facilitating its handling.

[0026] Working principle:

[0027] The lifting rod 104 is restricted by the limit housing 103 so that the lifting rod 104 cannot rotate. The drive reduction motor 102 is driven to rotate the threaded rod 105, and then the lifting rod 104 drives the hanging mechanism 6 to lift and lower, so that the display height of the model drawing can be adjusted. The cross bar 601 is unfolded and kept horizontal, then the lower part of the support rod 401 is aligned with the end of the support base 402, and finally the pin shaft 403 is inserted into the holes of the two, so that the support rod 401 and the support base 402 are fixed, so that the support rod 401 supports the cross bar 601. At the same time, the pin shaft 403 can be removed when not in use, so that the cross bar 601 is parallel to the lifting mechanism 1, thus completely reducing the volume of the device, and then facilitating its handling. By pushing the retracting assembly 604, the slider 603 moves left and right inside the chute 602, and then the distance between the two retracting assemblies 604 is adjusted to adapt to model drawings of different lengths. The micro motor 6041 is driven, and the retracting roller 6043 retracts or releases the retracting roller 6043, so as to adjust the distance between the upper and lower long tail clips of the cable 6044, and then it is applicable to model drawings of different widths.
