By adopting the scheme, the push rod 6 can smoothly slide into the groove 52 and slide out of the groove 52, and the use of the ligature device can be ensured to be smooth.
Specifically, as shown in fig. 4, at least part of the stretch yarn cutting rod 5 extends into the first inner cavity of the first housing 11, and an elastic member 7 for connecting with the stretch yarn cutting rod 5 is disposed in the first inner cavity of the first housing 11, and the elastic member 7 is used for resetting the rotated stretch yarn cutting rod 5, so that the convenience of the ligature device is further improved. Further, as shown in fig. 5, the first section 21 of the second housing may further be provided with a second stopper 212, and the second stopper 212 is used for limiting the elastic cord cutting bar 5 when the elastic cord cutting bar 5 is reset. With the above-mentioned arrangement, the elastic member 7 and the second stopper 212 cooperate to enable the stretch wire cutting rod 5 to be substantially parallel to the air tube 3 (or the second housing) in a non-tangential state (i.e., in a state in which the trigger assembly 12 is not pulled), which is advantageous for reducing the overall volume of the ligature apparatus.
Specifically, as shown in fig. 1 and 3, a positioning column 231 is provided on the outer side of the second housing of the present embodiment, and the elastic wire cutting rod 5 can be connected to the second housing through the positioning column 231. The structure is simple, the connection mode of the second shell and the elastic thread cutting rod 5 is simplified, and the integral structure of the ligature device is further simplified. It should be noted that the positioning post 231 does not fix the elastic wire cutting rod 5 to the second housing, and the elastic wire cutting rod 5 can rotate around the positioning post 231.
