[0003] In the above-described prior art technique, the needle is advanced to the tip of the base in a state in which one end of the base is held by a needle holding a yarn by a nipping mechanism of a thread provided inside the base, The yarn is supplied to the guide needle through which the yarn is fed by the hook lever, and the knitted yarn is moved to the inside of the base along the set orbit, and the two yarns are knotted by a knot mechanism provided inside the base, The tack is attached to the thread ring.

In contrast to the fasteners made of synthetic resin that attach the tack to the tackle, the tackle has the advantage of being able to attach the tackle conveniently, .

However, since the end portion of the yarn to which the tack is attached is sandwiched by the sandwiching mechanism provided in the inside of the base, if the sandwiching mechanism does not sandwich the yarn, a ring can not be formed and the tack can not be attached. There has been a problem in that it is inconvenient to repeatedly operate the lever of the selected key several times until it can be clamped.

In addition, since the middle portion of the thread with the tack is hooked and the thread loop is knotted with two threads, the sewing thread is consumed in a great amount, and the knotted end portion has four threads, The scissors blade was easily worn out, so that it was troublesome discomfort to replace the knotting mechanism from time to time, and there was a defect in that the tassel of the tack was tight and the aesthetic sense was not high.

A tackle for attaching a tackle to a sewing machine, the tackle including a thread holding means provided at a hook portion of a hook lever for hooking a thread provided on a tacky gas body, The hook portion of the hook lever is sandwiched by the hooking means of the hook lever and guided to the knotting mechanism in the inside of the body so that the hook can be attached to the hook with one strand of thread.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tangential tight-fitting device for a hook lever which attaches a tuck to a single strand of sewing thread.

Another object of the present invention is to provide a hook lever of a tacky hook which is provided with a thread clamping mechanism so that when a thread supplied to a guide needle is hooked by a hook, Wherein the yarn is guided to a knot in the inside of the base, and a tack is attached to the yarn by a single strand.

Another object of the present invention is to provide a sewing machine which can reduce the consumption of a sewing thread to which a tack is attached by attaching a tack by attaching a tack to a tacked thread ring, And to provide a true collimating device of the lever.

It is still another object of the present invention to provide a hook lever of a tactile gun which is easy to handle, easy to manufacture, equipped with a mechanism for holding a thread in a hook lever outside the base, Device.

The present invention relates to a guide needle which is fixed to a tip end of a tacky gun and passes through a tack to guide a loop, a needle which moves forward and backward to feed a thread for forming a ring for attaching a tack to the guide needle to the guide needle, A hook lever for pulling the yarn supplied to the guide needle into the base and a yarn strap for extending a middle portion of the yarn drawn when the yarn is pulled by the hook lever forward to form a longer length of the yarn loop, And a knot mechanism for cutting the excess yarn forming the loop by knotting the yarn end guided by the lever is provided so as to attach the tag to the sewing thread,

 A hook provided on the hook lever to hook the thread supplied to the guide needle; a clamp lever which is bent in a stepped shape formed by a spring and a support shaft on the hook lever; and a pawl which pierces the hook at the tip of the clamp lever, And the hook lever is pushed by the hook of the thread provided at the tip of the gas when the hook lever is operated to move downward and the yarn supplied to the guide needle is hooked, And an operating member provided on the bent portion of the nipping lever to open downward from the hook to project downward.

The holding levers of the holding mechanisms of the hooks provided on the hook levers take a form corresponding to the hook levers and appear as if the hook levers of the north digits are apparently superimposed on one another, and the holding levers are provided on the outer edge of the holding levers, So that the nip lever can be prevented from spreading inward.

Further, the actuating piece provided at the lower end of the nipple lever is exposed to the bent portion of the lower end of the hook lever in the form of a triangle bottom, and the exposed lower portion is received by the leg of the thread provided at the front end portion of the gas.

When the operation lever of the tactile gun of the present invention is once pulled and then released, a driving mechanism provided inside the base is linked with the reciprocating operation of the operation lever to organically interlock the guide rail Then, it is moved to the horizontal straight line in front of the gas, and the yarn is fed into the guide needle passing through the tack and article. At this time, both sides of the needle are provided with long grooves, and the thread is threaded into the needle hole along the groove. As the needle advances, the thread is freely supplied from the rear of the needle and the thread end is lightly caught between the guide needle and the thread needle .

In the initial stage of the backward movement of the yarn needle inserted into the guide needle, a lightly threaded end between the guide needle and the yarn needle is delayed, and a part of the thread is pushed rearward along the needle in the needle hole, .

 The small thread loop is exposed in the notched gap of the tubular guide needle side and the hook lever that moves along the predetermined orbit synchronously with this timing is operated downward to hook the thread loop exposed from the guide needle. As the hook lever is moved downward to engage the thread collar, the lower edge of the operating lever of the clamp lever is brought into contact with the thread of the thread provided at the tip of the gas so that the clamp lever is operated in the upward direction opposite to the hook lever, The nipping portion that has closed the hook is opened and the thread can be easily hooked by the hook.

When the hook lever is moved upward, the operating plate pressed on the bar is separated from the bar, and the nipping lever is returned to the original position by the elastic force of the spring provided on the supporting shaft of the nipping lever. Hold the thread tightly.

Unlike the case where the hook is hung in the middle of the yarn, the yarn is pulled by gripping the yarn end, so that the yarn is easily loosened in the needle hole for feeding the yarn, so that one yarn is guided to the knot mechanism provided inside the base. The needle which synchronously feeds the yarn is also retracted so that the yarn sandwiched by the hook and the yarn of the needle are combined and guided to the knotting mechanism side to form a loop for attaching the knot by the knotting mechanism and the extra yarn is cut It is cut by scissors.

By this operation, one strand of yarn is attached, and this series of operations is originally achieved by interlocking the operating mechanism provided in the base body.

In the present invention, since the yarn end is pinched by the hook lever and the yarn is hooked, the yarn is not skimmed from the hook unlike the case where the bare hook hooks the middle portion of the yarn, so that the tensile resistance of the yarn is not high, It is easy to attach a tuck with a knot of one thread.

Further, since the thread clamping mechanism is mounted on the hook lever and the thread clamping mechanism is actuated only when the hook hooks the thread to clamp the thread, the clamping operation of the thread is ensured and the clamping mechanism has no faulty element, Can be used.

Since the yarn hooking mechanism is provided in the hook lever of the tactile gun to hold the yarn caught in the hook, one yarn can be guided to the knot inside the base, and the tack can be attached to the yarn with one yarn.

In addition, by attaching the tack to the tackle with a thread ring, the consumption of the sewing thread to which the tack is attached can be saved, and the wear rate of the cutting edge of the cutter can be reduced.

In addition, since the hook lever is provided on the hook lever outside the base body, it is easy to handle, easy to manufacture, securely holding the thread, and can be attached at one time.
