1 side, and limit film 27 is threadedly coupled with screw rod 22, is fixed on screw rod 22 with this.When end cap 21 rotates, 21 edge of end cap
Screw rod 22 moves axially and squeezes compressed spring 23, and compressed spring 23 pushes buffer substrate tablet 26 and the first pressing line disk 24 mobile, from
And realize the adjusting of the first pressing line disk 24 and 25 spacing of the second pressing line disk, so that tension disk 2 can be suitably used for the suture of different thicknesses.
As shown in figure 3, tension assembly 3 includes that line hooks 31, sliding slot 32, adjustable spring 33, sliding block 34 and bolt 35.Line hooks 31
It is rectangle frame structure, quantity two, and two lines hooks 31 are located at 2 top two sides of tension disk.Sliding slot 32 opens up online
31 middle parts are hooked, line is hooked 31 up and down so that suture passes through.The length direction of sliding slot 32 is consistent with the length direction that line hooks 31,
And the sliding of sliding block 34 is connected in sliding slot 32.Sliding block 34 and suture contradict, and so that suture is kept tension with this.34 both sides of the edge of sliding block
It is also connected with flange 341, flange 341 and line hook 31 upper surfaces and contradict.Adjustable spring 33 is mounted in sliding slot 32, one end
It is fixed with 32 end of sliding slot, the other end and sliding block 34 are fixed.Fixed online hook side of 31 sides towards head 1 of bolt 35, and
Bolt 35 has multiple, and multiple bolts 35 are different in size, hooks 31 length directions arranged distribution from short to long again from long to short along the line.Machine
Multiple jacks 11 are offered on first 1 so as to the insertion of bolt 35, jack 11 is along 1 length direction arranged distribution of head, and jack 11 counts
Amount is more than 35 quantity of bolt.Since bolt 35 is different in size, so that the spacing that line hooks between 31 and head 1 is adjusted；And it inserts
Hole 11 adjusts relative position of the line hook 31 on head 1 along 1 length direction arranged distribution of head, substantially increases line
Hook 31 scope of application.
As shown in Figure 1, Figure 3, detection components 4 include conductive column 41, conducting block 42 and indicating member 43.Conductive column 41 is installed
One end of online hook 31, each line hook 31 ends and are fixed with two conductive columns 41.Conducting block 42 is fixed on sliding block 34 towards conduction
When the side of column 41, suture and sliding block 34 contradict, adjustable spring 33 is compressed；When suture disconnects, adjustable spring 33, which pushes, to be slided
Block 34 slides to conductive column 41, when conducting block 42 and the conflict of conductive column 41, is electrically connected successfully between two conductive columns 41.And it warns
Component 43 includes buzzer 431 and indicator light 432, and buzzer 431 is embedded at 1 top of head, and buzzer 431 and conductive column 41
Electrical connection, when any line, which hooks the conductive column 41 on 31, to be connected to, buzzer 431 sounds, and there are two indicator lights 432, is embedded in machine
First 1 top is simultaneously located at 431 side of buzzer, and two distributions of indicator light 432 hook the conductive column 41 on 31 with two lines and are electrically connected.When
When one line hooks conducting block 42 and the conflict of conductive column 41 on 31, corresponding indicator light 432 is powered, and indicator light 432 shines.
As shown in Fig. 2, be also equipped with clamping component 5 on tension disk 2, as shown in connection with fig. 4, clamping component 5 include cylinder 51,
Connecting rod 52, movable block 53, adjusting rod 531, accessory 54, push rod 55 and elastic string 56.There are two cylinders 51, is located at folder
2 two sides of line device, and its inner hollow, movable block 53 and accessory 54 are mounted in it.Connecting rod 52 is mounted on 51 two sides of cylinder,
It is used to support cylinder 51.Wherein, 52 one end of connecting rod of 51 side of cylinder and 51 outer wall of cylinder are hinged, the other end and 26 side of buffer substrate tablet
Wall is hinged；52 one end of connecting rod of 51 other side of cylinder and 51 outer wall of cylinder are hinged, and the other end and limit film 27 are side walls hinged.It is mobile
Block 53 is circular plate structure, and sliding is connected in cylinder 51.Adjusting rod 531 is hinged on 53 two sides of movable block, and movable block 53
The adjusting rod 531 of two sides is side walls hinged with the first pressing line disk 24 and the second pressing line disk 25 respectively.It is also provided on 51 side wall of cylinder
For the mobile shifting chute 511 of adjusting rod 531.Accessory 54 includes the first magnetic patch 541 and the second magnetic patch 542, the first magnetic patch 541
Be embedded in movable block 53, the second magnetic patch 542 is fixed on the one end of the inside of cylinder 51 far from tension disk 2, and the first magnetic patch 541 with
Second magnetic patch 542 is magnetic attracting.The rod-like structure cylindrical of push rod 55, one end and movable block 53 are fixed, and the other end is through circle
Cylinder 51 extends to 51 outside of cylinder, offers the aperture being pierced by for push rod 55 on cylinder 51.Push rod 55 extends the one of cylinder 51
Circular hole 551 is offered on end, circular hole 551 for suture for passing through；55 end of push rod is also provided with arc groove 552, arc groove 552
Both ends extend to 55 two sides of push rod, and elastic string 56 is worn wherein, and 56 both ends of elastic string are fixed with 51 end of cylinder.Work as suture
When disconnection, the tension on suture disappears, and elastic string 56 pushes push rod 55 to slide into cylinder 51, and movable block 53 is in push rod 55 at this time
It moves under the action of attraction between thrust and the first magnetic patch 541 and the second magnetic patch 542 to the second magnetic patch 542, and moves
The adjusting rod 531 of 53 two sides of block will drive the first pressing line disk 24 and the second pressing line disk 25 close to each other, thus will be by the first pressure
Suture between drum 24 and the second pressing line disk 25 clamps.
When the present embodiment is in use, the line that suture need to only be sequentially passed through to 2 side of tension disk hooks 31,2 side of tension disk
The line of 2 other side of push rod 55, the push rod 55 of 2 other side of tension disk and tension disk hooks 31, when sewing machine works normally, on suture
Tension adjustable spring 33 is compressed, conductive column 41 is separated with conducting block 42；Meanwhile suture is exposed at push rod 55 outside cylinder 51
Portion, and elastic string 56 is stretched.When the suture of 2 side of tension disk disconnects, corresponding push rod 55 is under the action of elastic string 56
53 slid inward of movable block is driven, drives the first pressing line disk 24 and the second pressing line disk 25 close to each other with this, thus will be by the
Suture between one pressing line disk 24 and the second pressing line disk 25 clamps.After suture is clamped, the seam of side at 2 broken string of tension disk
Line loses tension, and the suture of the other side does not lose tension, loses the adjustable spring 33 of tension side for conducting block 42 and conductive column
41 contradict, so that corresponding indicator light 432 lights, buzzer 431 sounds, realize suggesting effect with this, have distinguished 2 liang of tension disk
The region of side finds broken string convenient for operator, improves working efficiency.
Embodiment 2：As shown in figure 5, the present embodiment the difference from embodiment 1 is that, line hook 31 sides bolt 35 row
Column mode hooks 31 length directions in the present embodiment, along bolt 35 and first arranges from long to short again from short to long.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
