At this time, due to the elasticity of the connecting spring 303, the two sets of plug plates 304 are reset and then plugged and fixed with the positioning column 301.

[0039] When the relevant personnel hold the handle and need to adjust it, they move the pin 313 outward to release the limit of the pin 313 and the plug hole 314, and then they can rotate the rotating column 310 so that the rotating column 310 drives the four groups of arc plates 309 to move along the guide rail 307, thereby making the four groups of arc plates 309 open or shrink. The relevant personnel use the handle to operate, which makes the relevant personnel more comfortable when using it. When the relevant personnel hold the four groups of arc plates 309 and rotate them, the cable 2 is tightened and moves. When the cable 2 moves, it will contact the two groups of cleaning plates 404, and then the dust and magazines on the outside of the cable 2 are cleaned through the cleaning plates 404, avoiding manual cleaning and achieving the purpose of saving time and effort.
