[0021] The moving device includes a forward and reverse bidirectional hollow screw 5, a fixed block 7, a moving block 15, a vertical plate 4, a drive shaft 19, and a strip protrusion 20. The top of the U-shaped base 1 is fixedly provided with a drive shaft 19 through the vertical plate 4, and the outer wall of the drive shaft 19 is slidably provided with a forward and reverse bidirectional hollow screw 5 through a strip protrusion 20. The outer walls at both ends of the forward and reverse bidirectional hollow screw 5 with opposite thread directions are respectively threadedly connected with a fixed block 7 and a moving block 15. The bottom of the fixed block 7 is fixedly connected to the U-shaped base 1, and the outer wall of the moving block 15 is fixedly connected to the U-shaped frame 11 through a guide device.

[0023] The guide device includes a guide rail 12 and a guide plate 16.

By rotating the handwheel 18 and the drive shaft 19 by the handle, the drive shaft 13 is driven to rotate. The drive shaft 13 drives the forward and reverse bidirectional hollow screw 5 to rotate through the bar-shaped protrusion 20, so that the moving block 15 approaches the fixed block 7 and drives the lifting sleeve 26 to move backward to squeeze the cable reel 8 and finally cooperates with the driving roller 2 to lift the reel 8. The driving roller 2 is driven to rotate by the motor 17 and drives the cable reel 8 to rotate and pay out the line.
