The pushing portion 5 comprises a push plate 51 arranged on one side of the plug-in portion 3. The push plate 51 is of rectangular design and is used to pull the plug-in plate 31 and adjust the distance between the plug-in plate 31 and the fixed plate 8. Both sides of the bottom of the push plate 51 are rotatably connected to the end of the rotating plate 7 away from the connecting frame 33. The connecting frame 33 provides a fulcrum for the rotation of the rotating plate 7. The pushing portion 5 also comprises a limit plate 1 52 and a limit plate 2 53 arranged on one side of the push plate 51, wherein the limit plate 1 52 is as shown in FIG. Figure 1 As shown, its bottom abuts against the surface of the projection 2, as shown in FIG. Figure 2 As shown, the top of the second limit plate 53 is in contact with the inner wall of the plug-in slot 6, and the second limit plate 53 and the first limit plate 52 define the moving trajectory of the pushing portion 5. The second limit plate 53 and the first limit plate 52 are welded in parallel to the surface of the push plate 51. The distance between the second limit plate 53 and the first limit plate 52 is the longitudinal expansion space of the push plate 51, and the second limit plate 53 is located on the surface of the push plate 51 near the rotating plate 7.

[0034] A groove 54 is provided on one side of the limiting plate 1 52 close to the limiting plate 2 53. The cross section of the groove 54 is designed to be rectangular. Figure 1 As shown, a gap is created between the groove 54 and the protrusion 2 for the user to pull the push plate 51 .

Part of the pushing part 5 is plugged into the push groove 4. The lengths of the limiting plate 1 52 and the limiting plate 2 53 are both greater than the distance between the push plate 51 and the push groove 4, which limits the farthest distance of the plug-in plate 31, so that the telescopic spring 32 is always in the plug-in groove 6, reducing the probability of the plug-in plate 31 shaking left and right.

[0037] The effect achieved by the entire second embodiment is that when in use, by pulling the groove 54 on one side of the push plate 51, the top of the push plate 51 will move upward, and the part of the rotating plate 7 close to the push plate 51 will move along with it, and then under the action of the connecting frame 33, the plug-in board 31 will be pulled into the plug-in slot 6 until it is as shown in FIG. Figure 2 As shown, at this time, the winding roller 1 and the film slitting and winding machine are installed, and then the push plate 51 is released, and the plug-in plate 31 is reset to the position under the elastic force of the telescopic spring 32. Figure 1 Position, increase the overall length of the winding roller 1, when the film slitting and winding machine needs a shorter winding roller 1, the end of the plug-in plate 31 away from the winding roller 1 will be squeezed by the film slitting and winding machine, so that the length of the winding roller 1 is shortened, realizing the real-time adjustment function.
