Technical scheme: in order to realize above purpose, the utility model provides a kind of needle-threader, comprising: driving lever, crochet hook connecting portion, crochet hook and be connected the flexible connecting rod of sewing machine head below; Said driving lever is fixed in the below of flexible connecting rod; Said crochet hook connecting portion one end is connected with driving lever, and the other end is connected with the tail end of crochet hook, and said crochet hook front end is provided with crotch, and said crochet hook can pass the pin hole of sewing needle.
The invention also discloses the method for using of above-mentioned needle-threader, the concrete steps of this method are following:
(A) with the shank of the fixedly sewing needle of the head of sewing machine below position of turning up full blast;
(B) driving lever of threading apparatus is drop-down, the flexible connecting rod that is connected with sewing machine head exposes;
(C) driving lever is pressed to extreme lower position, then driving lever is turned round, make the crochet hook front end that is connected with the crochet hook connecting portion pass the pin hole of sewing needle;
(D) sewing thread is snapped in the crotch of crochet hook;
(E) and then with driving lever rotate forward, the crochet hook band the pin hole that the sewing thread that snaps in the crochet hook crotch passes sewing needle, has accomplished the threading process of sewing needle;
(F) decontrol driving lever at last, driving lever is risen be reduced to original position.
Needle-threader is provided with conductor rod described in the utility model, and said conductor rod is connected on the driving lever, and conductor rod is vertical with driving lever, and said conductor rod front end below is provided with groove; The setting of said conductor rod is passed sewing thread and is difficult for behind the sewing needle pin hole from pin hole, marking, and making threads a needle can accomplish fast and accurately.
A kind of method for using of needle-threader, the concrete steps of this method are following:
(A) with the shank of the head of sewing machine below position of turning up full blast;
(B) driving lever of threading apparatus is drop-down, the flexible connecting rod that is connected with sewing machine head exposes, and sewing thread is hooked in the groove of front end of conductor rod; Sewing thread snapped in the groove of the front end of conductor rod before the crotch that snaps in crochet hook; Make sewing thread before the crotch that gets into crochet hook, have a transition buffer; After sewing thread in the crochet hook crotch passes the pin hole of sewing needle, under the lead effect of conductor rod, need not firmly traction; Can not skid off the crochet hook crotch, failure causes threading a needle;
(C) driving lever is pressed to extreme lower position, then driving lever is turned round, make the crochet hook front end that is connected with the crochet hook connecting portion pass the pin hole of sewing needle;
(D) sewing thread is snapped in the crotch of crochet hook;
(E) and then with driving lever rotate forward, the crochet hook band the pin hole that the sewing thread that snaps in the crochet hook crotch passes sewing needle, has accomplished the threading process of sewing needle;
(F) decontrol driving lever at last, driving lever is risen be reduced to original position.
Beneficial effect: the advantage of the utility model is following: in the utility model, through needle-threader, can threading be moved simple, convenient, fast and accurate realization sewing needle, the whole operation method is simple, and easy operating is realized.
