[0029] A second magnet 401 is installed at the bottom end of the movable block 402, and the position of the second magnet 401 corresponds to the position of the pressing plate 12 and the first magnet 3 one by one, and the magnetic pole of the second magnet 401 is opposite to the magnetic pole of the first magnet 3;

[0030] The connecting rope 403 is in a tensioned state, and the connecting rope 403 is located inside the base 1 and is distributed in a U shape;

[0031] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, when in use, the pressing plate 12 is moved downward to push the movable block 402, and the first magnet 3 is attracted to the second magnet 401 to move one end of the connecting rope 403, and then the other end of the connecting rope 403 pulls the guide rod 7 downward, so that the wire loop 8 enters the inside of the clamping groove 17, so as to achieve timely fixation of the broken yarn;

[0032] A flap 16 is installed on the outer side of the protective cover 9;

[0033] The top of the flip cover 16 and the top of the protective cover 9 form a flip structure through a connecting shaft, and the bottom of the flip cover 16 and the inner side of the protective cover 9 are snap-fitted;

[0034] Specifically, Figure 1 , Figure 2 As shown, when in use, the flip cover 16 is used to open one side of the protective cover 9, so as to facilitate cleaning of the fluff inside the protective cover 9;

[0035] A support frame 5 is installed at the top of the base 1 on one side of the inlet and outlet 15, and a clamping groove 17 is opened at the top of the support frame 5;

[0036] The width and length of the clamping groove 17 are both greater than the diameter of the wire loop 8. The wire loop 8 forms an up-and-down sliding structure with the support frame 5 through the action of the guide rod 7 and the guide groove 6.

[0037] The bottom ends of the clamping grooves 17 are provided with guide grooves 6, the guide grooves 6 are penetrated by guide rods 7, and the top ends of the guide rods 7 extend to the inside of the clamping grooves 17 and are provided with wire loops 8, and the inside of the clamping grooves 17 outside the guide rods 7 are provided with second springs 18, and the top ends of the second springs 18 abut against the bottom ends of the wire loops 8;

[0039] Working principle: When the utility model is used, firstly one end of the yarn is passed through the first wire ring 8, and then the yarn is passed through the inlet and outlet 15, the cleaning hole 13, the cleaning ring 14 and the inlet and outlet 15 at one time, and then passed through the second wire ring 8, so as to connect the yarn with the winding drum on the automatic winder, and utilize the winding of the winding drum to achieve the guiding effect of the yarn, wherein when the yarn passes through the cleaning hole 13 and the cleaning ring 14, the friction effect on the yarn is utilized to intercept the fluff outside the yarn, so as to achieve the cleaning effect;

[0040] Secondly, since the first spring 10 is in a compressed state, it generates a driving force on the telescopic rod 11, so that the telescopic rod 11 is extended and the pressing plate 12 is pressed downward to ensure that the yarn is in a tensioned state. When the yarn breaks, the tensioning force of the yarn disappears, so that the first spring 10 drives the pressing plate 12 to move downward, so that the bottom end of the pressing plate 12 contacts the top end of the movable block 402 and pushes the movable block 402 to move downward;

[0041] Finally, as the distance between the movable block 402 and the first magnet 3 gets closer, the attraction between the two increases, so that the movable block 402 drives one end of the connecting rope 403 to move downward, causing the other end of the connecting rope 403 to move, and the connecting rope 403 pulls the guide rod 7 to move downward, thereby compressing the second spring 18 and causing the wire loop 8 to enter the interior of the clamping groove 17, so that the yarn passing through the wire loop 8 is bent so as to be clamped by the support frame 5, thereby achieving timely fixation of the broken yarn and preventing the yarn from falling off.
