The transmission line 17 can be wound by providing the central shaft 2 and the pillar 8, and the circular cover 7 can be controlled by rotating the central shaft 2 to control the length of the transmission line 17.

[0023] A handle 9 is fixedly connected to the upper end surface of the central rotating shaft 2, and a handle 10 is fixedly connected to the upper surface of the handle 9. A round hole 11 is opened at the upper end of the handle 10. A groove similar to the handle 9 is arranged above the cylinder 3, so that the handle 9 can enter the cylinder 3 to lock the rotation of the handle 9 and prevent the transmission line 17 from changing after the length is adjusted.

[0024] The upper end surface of the cylinder 3 is rotatably connected with a vertical shaft 12, and a pressing block 13 is fixedly connected to the left surface of the vertical shaft 12. The shaft connecting the cylinder 3 and the pressing block 13 is the vertical shaft 12 set on the cylinder 3. The pressing block 13 can be horizontally rotated relative to the cylinder 3 with the vertical shaft 12 as the axis to open and release the handle 9 or close and press the handle 9. The pressing block 13 is pressed downward to press the handle 9 into the groove so that it cannot rotate, thereby achieving the effect of locking the handle 9 and the central shaft 2, which can prevent the transmission line 17 from changing its accuracy after the length is adjusted.

[0025] A screw hole 14 is provided on the left side of the pressing block 13, and a screw rod 15 is arranged inside the screw hole 14, and the axial direction of the screw hole 14 is consistent with the axial direction of the screw rod 15. The screw rod 15 can be screwed into the screw hole 14 to fix the position of the pressing block 13 so that it will not change.

[0026] The lower end of the central rotating shaft 2 is fixedly connected with a cylindrical head 16 below the base plate 1. The cylindrical head 16 is fixed to the end of the central rotating shaft 2 to prevent the central rotating shaft 2 from falling off.

[0027] A vertically placed transmission line 17 is arranged inside the cylinder 3, passing through the cylinder 3 and being located between the central rotating shaft 2 and the support 8. The transmission line 17 passes through the cylinder 3 and is wound inside the cylinder 3 to achieve the effect of adjusting the length.

[0028] Working principle: The transmission line 17 can be wound by setting the central rotating shaft 2 and the pillar 8. When the length of the transmission line 17 needs to be adjusted, the control screw rod 15 is rotated to disengage the screw hole 14, and the pressure block 13 is rotated with the vertical rotating shaft 12 as the axis to release the handle 9, and then the handle 9 and the handle 10 are pulled out through the round hole 11, and then the handle 9 is rotated to drive the central rotating shaft 2 to rotate. The rotation of the central rotating shaft 2 will drive the rotating plate 5 to push the fixed block 6 to rotate, thereby rotating the round cover 7 and the pillar 8. The pillar 8 and the central rotating shaft 2 rotate at the same time, and the transmission line 17 can be wound or unwound to achieve the effect of adjusting the length of the transmission line 17.
