[0015] The position of the one side in bottom plate 1 is provided with movable slot three 23, movable slot three 23 is rotatably connected with screw thread rotating rod 24, the surface of screw thread rotating rod 24 is threadedly connected with screw thread sleeve plate 25, the top of screw thread sleeve plate 25 is penetrated to the outside of bottom plate 1 and is fixedly connected with the bottom of sliding plate 3.

[0016] The one side of bottom plate 1 is fixedly installed with variable frequency motor two 26, and the output end of one side of variable frequency motor two 26 is penetrated to the inside of movable slot three 23 and is fixedly connected with screw thread rotating rod 24.

[0017] The one side of fixed plate 2 is fixedly installed with variable frequency motor one 6, and the output end of one side of variable frequency motor one 6 is fixedly connected with main shaft 7, and the one side of main shaft 7 is penetrated to the outside of fixed plate 2 and is fixedly connected with one end of fixed frame 4 located on one side, and the one side of fixed frame 4 located on the other side is rotatably connected with one end of sliding plate 3.

[0018] The surface of movable rod 12 is sleeved with reset spring one 14, and the top and bottom of reset spring one 14 are fixedly connected with the top of movable slot one 10 and the top of fixed clamping block 11 respectively.

[0019] The top and bottom of the fixing frame 4 are fixedly connected with an external plate 15 on one side, and are fixedly connected with an auxiliary plate 16 on the other side. The internal part of the external plate 15 is provided with a movable slot two 18. The internal part of the movable slot two 18 is slidably connected with a limiting rod 17. The limiting rod 17 penetrates the external plate 15, the pull plate 13 and the auxiliary plate 16 in sequence on one side and is clamped with the auxiliary plate 16.

[0020] The center of the other side of the limiting rod 17 is provided with a supporting slot 21. The center of the internal wall of the movable slot two 18 is fixedly connected with a supporting rod 19. The supporting rod 19 penetrates to the internal part of the supporting slot 21 on one side and is clamped with the supporting slot 21. The surface of the supporting rod 19 is sleeved with a reset spring two 20.

[0021] Working principle: when the silk cylinder 5 needs to be replaced, the push plate 22 is first pushed outwards. The push plate 22 drives the limiting rod 17 to slide in the movable slot two 18. When the limiting rod 17 moves, the supporting slot 21 slides along the supporting rod 19, and the reset spring two 20 is compressed at the same time. When the limiting rod 17 is completely removed from the auxiliary plate 16, the constraint of the limiting rod 17 on the pull plate 13 is released. At this time, the pull plate 13 is in a movable state. After the constraint of the limiting rod 17 is released, the pull plate 13 is pulled outwards. The pull plate 13 drives the fixed clamping block 11 to slide in the movable slot one 10 through the movable rod 12. When the fixed clamping block 11 moves, the reset spring one 14 is compressed, and gradually removed from the fixed slot 9 of the silk cylinder 5. When the fixed clamping block 11 is completely removed from the fixed slot 9, the fixing of the silk cylinder 5 is released. At this time, the silk cylinder 5 can be taken out or replaced. After the fixing of the silk cylinder 5 is released, the variable frequency motor two 26 is started. The variable frequency motor two 26 drives the threaded rotating rod 24 to rotate. Since the threaded rotating rod 24 is in threaded connection with the threaded sleeve plate 25, the threaded sleeve plate 25 will move along the axial direction of the threaded rotating rod 24. The movement of the threaded sleeve plate 25 drives the sliding plate 3 to move, thereby adjusting the distance between the two fixing frames 4 to adapt to silk cylinders 5 of different sizes or to install the silk cylinder 5.
