Refer to shown in Fig. 4 and Fig. 5, in order to clearly show that the structure pattern of the thread cutter 2, omit described in drawing
Base 21, kettle axle bed 22, kettle axis 222, lower feed spool 25, the structure of rotating shuttle 26 and lower drawing-inroller 28, as shown in the figure, described cut
Line apparatus 2 is mainly assembled in the side seat 23, and is mainly made of a cutter group 30 and a transmission device 40.
The cutter group 30 is adjacent to the pin hole 271 of the pinhole plate 27, and positioned at the rotating shuttle 26 and lower drawing-inroller 28
Between, wherein, the cutter group 30 has a fixed cutting tool 31, a moving cutting tool 32 and a Trap shell splinter 33, the fixation
Cutter 31 is installed on the pin holder 231b, and positioned at the lower section of the pinhole plate 27, and the fixed cutting tool 31 has one to lean on
It is bordering on the counteredge 311 of the pin hole 271.
As shown in the figure, the moving cutting tool 32 of the cutter group 30 is positioned at the lower section of pin hole 271 so that the moving cutting tool
Longitudinal arrangements are presented in both 32 and fixed cutting tool 31, and the moving cutting tool 32 has the hook that a connecting pin 321, one is located at end
The guidance part 323 and one that groove portion 322, one is located at end side is formed at the mobile blade 324 for hooking 322 rear of groove portion,
Wherein, 32 Moveable assembled of moving cutting tool is in the arc track 231d of the movable tool apron 231c so that the activity is cut
Knife 32 can be in the arc track 231d along a center of rotation 231e parallel to the lower axle 24 and then swing, in this reality
Apply in example, the activity tool apron 231c is equipped with two pressing plates 34, and the partial section of the pressing plate 34 is covered in the arc track
231d so that two pressing plate 34 can prevent the moving cutting tool 32 to be located away from the arc track 231d.
Refer to shown in Fig. 6 A to Fig. 6 C, the moving cutting tool 32 is located in the arc track 231d and is located at one in institute
The initial position 325, one for stating 271 side of pin hole is away from the hooking position 326 and one of the initial position 325 close to institute
State and swung along the center of rotation 231e between 327 three of off-position of pin hole 271, wherein, when the moving cutting tool 32
When being rocked to the off-position 327 by the hooking position 326, the hook groove portion 322 of the moving cutting tool 32 can be by described
The underface of pin hole 271 so that the mobile blade 324 is contacted with the counteredge 311 and cuts off suture L (such as Figure 12 C
It is shown).
Refer to again shown in Fig. 4 and Fig. 5, the Trap shell splinter 33 of the cutter group 30 is assembled in the movable tool apron equipped with one
The group connecting part 331 and one of 231c is located at the crimping 332 of 331 side of group connecting part, wherein, the Trap shell splinter 33 itself
Flexible characteristic so that the crimping 332 is pushed against in the moving cutting tool 32, so that the moving cutting tool 32 is cut
During the disconnected suture L, the crimping 332 of the Trap shell splinter 33 can clamp the suture L disengaged by the rotating shuttle 26.
The transmission device 40 to drive the moving cutting tool 32 of the cutter group 30 along the center of rotation 231e into
Row longitudinal oscillation, make the moving cutting tool 32 sequentially the initial position 325, hooking position 326 and off-position 327 it
Between swung, as shown in the figure, the transmission device 40 have a fixed seat 41, a cam set 42, a connecting rod 43, an involution bullet
44 and one driver 45 of spring.The fixed seat 41 is fixedly connected on the side seat 23, and the cam set 42 be installed in it is described
Lower axle 24, and synchronous with the lower axle 24 equidirectional rotation can be carried out along X-axis.
In this embodiment, there is the cam set 42 one first cam 421 and one to be located at first cam 421 1
Second cam 422 of side, first cam 421 have one to be located at for the first through hole 421a and one that the lower axle 24 is worn
The lift path 421b of outer rim, and second cam 422 have a second through hole 422a worn for the lower axle 24 and
One is located at the backhaul pathways 422b of outer rim, wherein, the lift path 421b is driving the moving cutting tool 32 by the hook
Line position 326 is rocked to the off-position 327, and the backhaul pathways 422b is driving the moving cutting tool 32 by described
Initial position 325 is rocked to the hooking position 326.
Refer to shown in Fig. 7 A and Fig. 7 B, by multiple screws from the wheel hub outer rim of first cam 421 through described
First through hole 421a so that the end face of the multiple screw contacts at the surface of the lower axle 24 at the same time, so that described
One cam 421 is fixed on the lower axle 24, causes first cam 421 can not be rotated relative to the lower axle 24, together
Second cam 422 described in sample is equally to be fixed on the lower axle 24 by multiple screws.
, can be relative to however, first cam 421 is not when the multiple screw contacts at the surface of the lower axle 24
The lower axle 24 is rotated, and thereby, relative position between first cam 421 and second cam 422 can be via
Rotate and be adjusted, and then change the relative angular position between the lift path 421b and backhaul pathways 422b at the same time,
Cause to adjust the moving cutting tool 32 and the hooking position 326 is rocked to (or by the hooking position by the initial position 325
Put 326 and be rocked to the off-position 327) duration of oscillation it is poor.
In this preferred embodiment, meeting shape has angle between the lift path 421b and backhaul pathways 422b, and institute
State the first cam 421 and relative position between second cam 422 is adjusted via rotation so that the lift path
Angle between 421b and backhaul pathways 422b becomes larger (as shown in Figure 7 B), and then is rocked to ahead of time by the initial position 325
The swing sequential of the hooking position 326 (or postponing to be rocked to the off-position 327 by the hooking position 326), conversely,
Change the relative position between 421 and second cam 422 of the first cam so that the lift path 421b and backhaul pathways
Angle between 422b diminishes, and then postpones the moving cutting tool 32 and be rocked to the hooking position by the initial position 325
The swing sequential of 326 (or the off-position 327 is rocked to by the hooking position 326 ahead of time).
Refer to again shown in Fig. 4 and Fig. 5, main one first body of rod by mutually assembling of the connecting rod 43 of the transmission device 40
431 are formed with one second body of rod 432, and first body of rod 431 of the connecting rod 43 is assembled in the connecting pin of the moving cutting tool 32
321, and second body of rod 432 is connected to a swing arm 434 by a link pin 433, the swing arm 434 is pivotally connected to described
Fixed seat 41, and it is used for the selective roller 435 for contacting at the cam set 42, in this embodiment, the connecting rod with one
Pin 433 is pivotally connected to second body of rod 432, and the roller 435 can contact at first cam 421 and second at the same time
Cam 422.
Refer to shown in Fig. 8 A and Fig. 8 B, since the swing arm 434 is articulated in the fixed seat 41 so that the roller
435 can be contacted with the contact position 435b of the cam set 42 in a separation point position 435a and one for being located away from the cam set 42
Between move back and forth along X-axis, and the roller 435 moves back and forth between the separation point position 435a and contact position 435b
During, the swing arm 434 can drive the connecting rod 43 to be moved via the link pin 433.In this embodiment,
