[0037] Please refer to Figures 1 to 5 , in this embodiment, the pull tab structure 30 provided by the present utility model includes a first component 31, a connecting piece 32 and a second component 33. The first component 31 is rotatably connected to the connecting piece 32, and the connecting piece 32 is connected to the second component 33. The first component 31 is rotatably connected to the second component 33 through the connecting piece 32.

[0038] Please refer to Figures 1 to 2 , the first component 31 includes a first cross bar 311, a second cross bar 313 and two connecting rods 312. The first cross bar 311 and the second cross bar 313 are arranged in parallel. Both ends of the first cross bar 311 are fixedly connected to the two connecting rods 312 respectively. Both ends of the second cross bar 313 are fixedly connected to the two connecting rods 312 respectively. The connection points of the first cross bar 311, the second cross bar 313 and the connecting rods 312 are located at the ends of the connecting rods 312.

[0039] The first cross bar 311 is used for the first component 31 to be rotatably connected to the cap 20 of the slider, and the first cross bar 311 is rotatably connected to the cap 20 through the connection hole 21; the second cross bar 313 is used for the first component 31 to be connected to the connecting piece 32.

[0040] A receiving portion 314 is provided on the first component 31. The above-mentioned first cross bar 311, second cross bar 313 and two connecting rods 312 enclose the receiving portion 314, and the receiving portion 314 can cooperate and be snap-connected with the connecting piece 32.

[0041] Please refer to Figures 1 to 3The connecting member 32 includes a fixing portion 321 and a connecting portion 322. The fixing portion 321 is roughly a rectangular plate-shaped structure. The connecting portion 322 is arranged at the top of the fixing portion 321, and the connecting portion 322 is connected to the fixing portion 321. A jaw 3221 is arranged on the side of the connecting portion 322 away from the fixing portion 321. The top of the jaw 3221 is open, and the jaw 3221 is configured to be able to produce deformation. When the first component 31 is connected to the connecting member 32, the second cross bar 313 is located in the jaw 3221. A clamp or the like is used to clamp the two sides of the jaw 3221 to deform it.

[0044] The first clamping block 332 is fixedly arranged on the inner bottom surface of the injection molding body 331, and the first clamping block 332 is used to cooperate and engage with the accommodating portion 314 on the first component 31; the second clamping block 333 is fixedly arranged on the inner bottom surface of the injection molding body 331, and the second clamping block 333 is roughly U-shaped. The second clamping block 333 is used to cooperate and engage with the cap 20 of the slider, and the second clamping block 333 is cooperated and engaged with the cap 20 from the side of the cap 20.

[0045] With such arrangement, the second component 33 is fixed in position by the first clamping block 332 and the accommodating portion 314 and the second clamping block 333 and the cap 20 , which can prevent the pull-tab structure 30 from shaking and improve comfort.

[0046] The side of the first clamping block 332 close to the second clamping block 333 is also roughly U-shaped. The first clamping block 332 and the second clamping block 333 together form a receiving groove 334. When the second component 33 is turned over, the cap 20 of the slider is correspondingly received in the receiving groove 334.

[0047] The injection - molded body 331 is provided with a receiving cavity 3312. The second clamping block 333 and the injection - molded body 331 together define the above - mentioned receiving cavity 3312.
