The embodiment of the utility model discloses pull head of zip fastener, including upper plate 1, hypoplastron 2 and restriction round pin 4, upper plate 1 is relative with hypoplastron 2, the front end bottom of upper plate 1 is equipped with articulated seat, the front end top of hypoplastron 2 is equipped with down articulated seat, articulated seat and the unsmooth cooperation of last articulated seat down, it is equipped with the hinge hole to go up articulated seat, lower articulated seat is equipped with down the hinge hole, hinge hole and lower hinge hole are passed to switching round pin 3, make upper plate 1 link to each other through switching round pin 3 is articulated with the front end of hypoplastron 2, thereby make upper plate 1 and hypoplastron 2 can relative rotation, provide the condition for unpacing the pull head apart.

One side of the upper plate 1 close to the lower plate 2 is provided with an upper insertion hole 11, one side of the lower plate 2 close to the upper plate 1 is provided with a lower insertion hole 21, when the lower plate 2 rotates to a limit position relative to the upper plate 1, the upper insertion hole 11 is communicated with the lower insertion hole 21, the limiting pin 4 is inserted between the upper insertion hole 11 and the lower insertion hole 21, the limiting pin 4 is used for limiting the positions of the upper plate 1 and the lower plate 2, and the upper plate 1 and the lower plate 2 are fixedly connected.

When the zipper puller is used, the puller is placed between two rows of zipper teeth, the lower plate 2 is pushed upwards, the lower plate 2 rotates relative to the upper plate 1 around the adapter pin 3, the lower plate 2 and the upper plate 1 are close to each other until the upper insertion hole 11 is communicated with the lower insertion hole 21, the limiting pin 4 is inserted between the upper insertion hole 11 and the lower insertion hole 21, the upper plate 1 and the lower plate 2 are limited to move, the puller is locked, and the puller is installed on the zipper teeth. On the contrary, the limiting pin 4 is pulled out, the lower plate 2 is pushed downwards, the lower plate 2 rotates around the adapting pin 3 in the direction away from the upper plate 1, the lower plate 2 is separated from the upper plate 1, the zipper head is separated from the zipper teeth, and the zipper head is convenient to replace.

To sum up, the utility model discloses the mode that links firmly of well upper plate 1 and hypoplastron 2 replaces the cooperation of hook groove joint by the pinhole cooperation, can effectively avoid the unexpected separation of pull head, connects more reliably.

The bottom integral type of upper plate 1 has set firmly upper core 12, and the bottom integral type of hypoplastron 2 has set firmly lower core 22, and upper core 12 is equipped with the joint arch, and lower core 22 is equipped with the joint recess, and upper jack 11 specifically is along transversely running through in the bellied circular through-hole of joint, and lower jack 21 specifically is along transversely running through in the circular through-hole of joint recess.

When the clamping protrusion is in clamping fit with the clamping groove, the upper insertion hole 11 is communicated with the lower insertion hole 21, and at the moment, the upper support core 12 and the lower support core 22 are combined to form a mandrel for controlling the combination or separation of the zipper teeth.

The utility model discloses still include U type buckle 5, when last branch core 12 and lower core 22 buckled mutually, with 5 joints of U type buckle in last branch core 12 and the two side of core 22 down, not only can prevent switching round pin 3 and inject round pin 4 and deviate from, can also make last branch core 12 and lower core 22 rely on the clamping-force that U type buckle 5 applyed reliably to link to each other, further guarantee that upper plate 1 and hypoplastron 2 reliably link to each other.

U type buckle 5 specifically is elastic buckle, makes U type buckle 5 rely on elastic force to press from both sides tight upper limb core 12 and lower core 22, still avoids U type buckle 5 because of frequent produced wearing and tearing of dismouting and the joint is not firm, is favorable to prolonging U type buckle 5's life. The U-shaped buckle 5 may be a plastic buckle formed by integral casting, or a metal buckle formed by stamping and rolling a thin steel plate, and the material of the U-shaped buckle 5 is not specifically limited herein.
