[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 5 shown, a wire winding and unwinding device for stage construction includes a base plate 1. Both ends of the base plate 1 are fixedly connected with supporting vertical plates 2 arranged correspondingly on both sides. A rotating shaft 3 is rotatably connected between the two supporting vertical plates 2. A rocker 21 for driving the rotation of the rotating shaft 3 is rotatably connected to one side of the supporting vertical plate 2. Not less than one wire winding roller 4 is rotatably connected to the rotating shaft 3. A limiting column is fixedly connected to the outer wall of the rotating shaft 3. A limiting groove 20 for cooperating with the limiting column is provided in the wire winding roller 4. Wire clamps 22 are fixedly connected to the outer walls of the wire winding rollers 4. Limiting retaining rings 5 are fixedly connected to both sides of the wire winding roller 4. A U-shaped adjusting frame 6 is fixedly connected to one of the limiting retaining rings 5. Connecting blocks 8 are slidably inserted into the U-shaped adjusting frames 6. Connecting grooves 11 arranged in an annular array and cooperating with the connecting blocks 8 are provided on the rotating shaft 3. A fixed slot is provided at the lower end of the connecting block 8. A fixed block 9 is slidably inserted into the fixed slot. The lower end of the fixed block 9 is slidably inserted into the connecting groove 11. A fixed spring 10 for cooperating with the fixed block 9 is provided in the fixed slot. Adjusting bolts 7 are threadedly connected to the upper ends of the U-shaped adjusting frames 6. The lower ends of the adjusting bolts 7 are rotatably connected to the upper ends of the connecting blocks 8.

[0022] The upper end of the base plate 1 is provided with at least one positioning mechanism cooperating with the winding roller 4, the positioning mechanism includes a fixed plate 12 fixedly connected to the upper end of the base plate 1, a limit ring 5 on one side of the winding roller 4 is slidably connected to one side of the fixed plate 12, the fixed plate 12 is provided with a through hole 13 cooperating with the rotating shaft 3, the fixed plate 12 is provided with a positioning slot 14 arranged in a ring array along the center of the through hole 13, a positioning column 15 is slidably inserted in the positioning slot 14, a positioning spring 16 cooperating with the positioning column 15 is fixedly connected in the positioning slot 14, one end of the positioning column 15 is rotatably connected with a ball 17, and one side of the limit ring 5 is provided with a positioning groove 18 arranged along the ring array and cooperating with the ball 17.

[0023] In specific use, the adjusting bolt 7 on one side of the winding roller 4 to be used is turned, and the adjusting bolt 7 is screwed into the U-shaped adjusting frame 6, pushing the connecting block 8 to slide downward, so that the fixing block 9 is inserted into the connecting groove 11 on the outer wall of the rotating shaft 3. If the fixing block 9 abuts against the outer wall of the rotating shaft 3 when sliding downward, the fixing block 9 slides into the fixing groove to squeeze the fixing spring 10 to deform, and the winding roller 4 is slightly rotated to rotate the fixing block 9 to the position corresponding to the connecting groove 11. Under the restoring elastic force of the fixing spring 10, the fixing block 9 is pushed to be inserted into the connecting groove 11 to complete the winding. The roller 4 is connected to the rotating shaft 3, and one end of the guide is connected to the wire clamp 22 on one side of the winding roller 4. The rocker 21 is turned to drive the rotating shaft 3 to rotate. Under the connection between the fixed block 9 and the connecting groove 11, the rotating shaft 3 drives the winding roller 4 to rotate for winding. When the winding roller 4 rotates, it drives the limit ring 5 on one side to rotate along the outer wall of the fixed plate 12. When the limit ring 5 rotates, due to the large rotation force of the rocker 21, the ball 17 is squeezed out of the positioning groove 18. At the same time, the ball 17 drives the positioning column 15 to slide into the positioning slot 14 to squeeze the positioning spring 16 to cause compression deformation.

[0024] If the winding roller 4 on one side is not needed, the adjusting bolt 7 is turned to pull the fixing block 9 out of the connecting groove 11. When the rotating shaft 3 rotates, the ball 17 is inserted into the positioning groove 18 under the thrust of the positioning spring 16. When the external force is small, the ball 17 will not slide out of the positioning groove 18, and the winding roller 4 will not rotate.
