[0029] As Figure 3 Shown, in the present embodiment, telescopic rod 203 is fixedly installed on the upper surface of no.

[0030] In the embodiment, the monofilament passes above the threading conductive sleeve 303 above the first support frame 201 and below the threading conductive sleeve 303 below the second support frame 202, so that the monofilament has an upward force on the threading conductive sleeve 303 below the second support frame 202. When the monofilament is broken, the upward force of the threading conductive sleeve 303 disappears, and the telescopic rod 203 is retracted under the elastic force of the spring 204, so that the T-shaped pressing rod 207 moves downward and abuts against the pressure sensor 209. When the pressure sensor 209 detects the pressure, it is detected that the monofilament is broken.

[0031] As shown in Figure 4 In the embodiment, the inside surface of the threading conductive sleeve 303 is fixedly provided with a conductive rod 305, and the side surface of the sleeve ring 205 is fixedly provided with a conductive slip ring 306. One end of the conductive rod 305 penetrates through the hollow rotating block 301 and is electrically connected to one end of the conductive slip ring 306. The other ends of the two conductive slip rings 306 are respectively electrically connected to a detection device 307 and a power supply 308. The conductive slip ring 306 can make the current flow when the threading conductive sleeve 303 rotates. The detection device 307 is electrically connected to the power supply 308.

[0032] In specific implementation, when the monofilament passes through the two threading conductive sleeves 303, an electric circuit is formed between the two threading conductive sleeves 303, the detection device 307, the power supply 308 and the monofilament. When the circuit is connected, the monofilament is normally conveyed. When the circuit is disconnected, the monofilament breakage is detected. At the same time, the pressure change detected by the pressure sensor 209 is combined to detect the monofilament breakage through two detection methods, so as to avoid the detection error caused by the large friction force and the pressure error of the pressure sensor 209, and improve the detection accuracy of the breakage.
