and next lower scissors frame 1 and upper shear shank 2 can also be sheared flexibly, on Shear shank 2 is connect by core screw 8 with lower scissors frame 1 and upper shear shank 2 is made to be directly connected to still protect with lower scissors frame 1 Relative motion is held, lower scissors piece 4, upper shear blade 5 and scissors tabletting 6, core are provided between lower scissors frame 1 and upper shear shank 2 Screw 8 runs through lower scissors piece 4, upper shear blade 5 and scissors tabletting 6, and lower scissors piece 4 is anchored on lower scissors frame 1 by screw, under Shear shank 1 is securedly mounted to lower scissors telescopic rod and is linked in scissors telescopic rod, and lower scissors frame 1 is equipped with copper sheathing 3, lower scissors 1 close-fitting of frame has copper sheathing 3 convenient for sliding on upper scissors telescopic rod, and the upper end of upper shear shank 2 is equipped with auxiliary presser thread needle 10, auxiliary The top of presser thread needle 10, which is equipped with, bears down on one first 15, and the crimping position of crimping foot 11 and upper shear shank 2 are closure in its natural state State, crimping foot 11 and auxiliary presser thread needle 10 on go here and there the compressed spring 14 having compression height it is essentially identical, the upper end of shift fork 18 It is close to upper shear shank 2, sliding block 12 is essentially identical in the upper and lower gap of 18 medial launder of shift fork, and auxiliary presser thread needle 10 is equipped with shift fork 18, sliding block 12 is stuck in centre by shift fork 18, and the side of shift fork 18 is equipped with sliding block 12, and sliding block 12 also has a U-lag, assists crimping Needle 10 is by the U-lag of sliding block 12, and for the purposes of rotate crimping foot 11 will not axially, and the U-lag position of sliding block 12 is located at Between 18 medial launder of shift fork, the lower section of sliding block 12 is equipped with locating piece 13, the adjustable bullet needed in actual work of locating piece 13 Power size, the lower section of locating piece 13 are equipped with compressed spring 14, and crimping foot 11 and auxiliary presser thread needle 10, which are all gone here and there, has compressed spring 14 simultaneously It is positioned by locating piece 13, rapid presser thread of the crimping foot 11 when replying, while crimping foot 11 and auxiliary may be implemented in compressed spring 14 The sliding block 12 and shift fork 18 helped on presser thread needle 10 can make crimping foot 11 not will increase crimping power while increasing crimping speed, make Increase speed when crimping foot 11 is sprung back with a set of major-minor crimping foot and two compressed springs 14, it is special that such change makes For 11 structure of crimping foot is compared to common scissors, in crimping, crimping is fast due to the elastic effect by two compressed springs 14 It spends faster, while crimping power is only still the power of a spring, will not influence crochet hook hook line, so that the scissors is can be suitably used for high speed and transport Turn, also more extensively, elastic force of the locating piece 13 to adjust compressed spring 14, the upper end of upper shear shank 2 is additionally provided with stirs applicability Pin 9 is stirred to be equipped on pin 9 and stirs seat 17, stirs seat 17 equipped with notch shield lining, notch shield lining is in upper shear shank 2 to keep Stability of the waste selvage yarn scissors in high-speed motion stirs pin 9 and upper shear shank 2 for the fastening of cone match screw, to ensure to connect What is connect is secured, stirs pin 9 and is fixed by screws on shear shank 2, stirs the U-lag on seat 17 and is placed on and stir pin 9, and stirs It is logical to stir seat 17 to keep stability of the waste selvage yarn scissors in high-speed motion in upper shear shank 2 for the notch shield bushing of pin 9 It crosses screw to hold tightly in upper scissors telescopic rod, live conductor foot 11, the size of the crimping power of crimping foot 11 are installed in the lower end of upper shear shank 2 It can be adjusted by crimping foot 11 and the locating piece 13 that be equipped with of auxiliary presser thread needle 10, crimping foot 11 is in crimping compared to commonly cutting It is sprung back faster for knife, while crimping power is constant, crimping foot 11 makes to assist presser thread needle 10 will not by the U-lag on shift fork 18 Axial rotation, the lower end of upper shear shank 2 be also equipped with it is useless cuts eccentric screw 16, it is useless cut eccentric screw 16 be adjustable lower scissors piece 4, The initial openings size of upper shear blade 5, the rear end of upper shear blade 5 are stuck in give up and cut on eccentric screw 16, therefore can be by slightly Rotation useless cut eccentric screw 16 to adjust the openings of sizes between lower scissors piece 4, upper shear blade 5, lower scissors piece 4, upper scissors Piece 5 is all cemented carbide structure, it is ensured that frictional force, resistance and wear resistance.

After installing, bearing down on one first 15 is pressed down, and is pushing shift fork 18, is touched during shift fork 18 pushes Sliding block 12 continues to push, and during at this moment pushing, spring force becomes two from one, during bearing down on one first 15 pushing Entire waste selvage yarn scissors is also forward extending out, when weft be located at the opening of crimping foot 11 neutralize scissors be open in when, bear down on one first 15 Lower pressure disappears, and crimping foot 11 clamps rapidly weft yarn because of the spring-force driven dual of two springs, clamps weft yarn in crimping foot 11 In the process, the spring force at crimping foot 11 from two becomes one again, so that crochet hook will not be by when hook weft yarn It influences, when crimping foot 11 fills weft, scissors also cuts weft yarn, and at this moment crochet hook insertion cloth cover hooks weft yarn, and pulls back same When coping block 15 be pressed down again, unclamp crimping mouth, entire waste selvage yarn scissors toward retraction, return to initial position.

In summary: the waste selvage yarn scissors apparatus of the utility model high speed Tucked-in selvage apparatus has used a set of major-minor crimping Foot and two compressed springs 14 increase speed when crimping foot 11 is sprung back, and such change compares special 11 structure of crimping foot For common scissors, in crimping due to the elastic effect by two compressed springs 14 crimping speed faster, while crimping Power is only still the power of a spring, will not influence crochet hook hook line, the scissors is made to can be suitably used for running at high speed, and applicability is also wider General, simple and ingenious structure, production and processing is at low cost, guarantees 11 rebound velocity of crimping foot, a side using two compressed springs 14 Face can make crimping foot 11 spring back when due to the elastic force of two compressed springs 14 speed faster, on the other hand due to sliding block 12 with dial The crimping power that 18 ingehious design makes crimping foot 11 still there was only a spring when pushing down weft is pitched, it will not be because of crimping power It is excessive and influence crochet hook hook yarn, and if common Single spring waste selvage yarn scissors is the elastic force for increasing single spring, pressed increasing The crimping power that also will increase crimping foot 11 while 11 rebound velocity of stitch influences crochet hook hook yarn.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
