[0041] Working principle: We first pass the cable through the two pressure rollers 30 and the inside of the cleaning box 32, and then pass through the cylinder 23 and fix it on the outside of the winding drum 11, and then drive the rotating shaft 7 to rotate by starting the motor 16, thereby driving the arc plate 9 to rotate, and then driving the winding drum 11 to rotate to automatically reel the cable, and at the same time, the rotating shaft 7 will also drive the active bevel gear 8 to rotate, thereby transmitting the force to the driven bevel gear 16, and the driven shaft 13 is driven to rotate through the driven bevel gear 16, thereby driving the driving wheel 14 to rotate, and then driving the belt 15 to rotate, and the force is transmitted to the driven wheel 18 through the belt 15, so that the driven wheel 18 can The rotating rod 17 rotates, and then drives the turntable 19 to rotate, thereby driving the fixed rod 20 to rotate, and the fixed rod 20 pushes the sliding frame 21 to reciprocate, thereby driving the column 22 to move, and then drives the cylinder column 23 to reciprocate back and forth, so that the cable can be evenly wound on the outside of the winding drum 11, and is restricted by the circular plate 12 to prevent the cable from slipping. At the same time, the front end of the fixed rod 10 inside the winding drum 11 is clamped inside another vertical plate 2, and the rear end is clamped inside one of the vertical plates 2 and the outside of the arc plate 9, so that it is convenient to take down the winding drum 11 and put a new winding drum 11 for winding;

At the same time, when the two pressure rollers 30 are rotated to different angles, the rotating shaft 26 will drive the rotating rod 33 to rotate, thereby driving the eccentric wheel 34 to rotate, and then squeeze the rotating rods 33 on the upper and lower sides to make them slide and adapt to the angle through which the cable passes. At the same time, the trapezoidal plate 37 will also squeeze the limiting plate 36, and then squeeze the spring 35, so that the spring 35 can pierce the elastic potential energy, and then give the trapezoidal plate 37 a force in the opposite direction, so that it can fit closely with the cable to improve the cleaning effect.
