[0034] The rotating member 122 has a first position and a second position on its rotation trajectory. When the rotating member 122 is in the first position, the snap-fit ​​block 1121 can enter and exit the through hole 1221. When the rotating member 122 is in the second position and the first pull tab 11 and the second pull tab 12 are connected, the rotating member 122 is clamped between the first main body piece 111 and the snap-fit ​​block 1121.

[0035] The rotatable and fixed pull tab assembly 1 and zipper of this utility model allow for the following: When the first pull tab 11 and the second pull tab 12 are separated, rotating the rotating member 122 at any angle to the first position allows the locking block 1121 to pass through the through hole 1221. Then, rotating the rotating member 122 at any angle to the second position clamps the rotating member 122 between the first main body piece 111 and the locking block 1121, thus fixing the first pull tab 11 and the second pull tab 12. Rotating the rotating member 122 at any angle to the first position allows the locking block 1121 to pass out of the through hole 1221, thus separating the first pull tab 11 and the second pull tab 12. The rotatable and fixed pull tab assembly 1 and zipper of this utility model allow for the detachable connection of the first pull tab 11 and the second pull tab 12. When the first pull tab 11 and the second pull tab 12 are connected, they prevent shaking and provide a certain degree of anti-theft effect.

[0036] Please refer to Figure 4 , Figure 5 Please also refer to Figure 2 The axial direction of the mounting hole 1211, the axial direction of the through hole 1221, and the rotation axis of the rotating part 122 are all parallel to the thickness direction of the second main body piece 121. When the first pull tab 11 and the second pull tab 12 are connected, the first main body piece 111 and the second main body piece 121 are parallel, which makes the overall structure simple.

[0037] Please refer to Figure 5 , Figure 6 and Figure 7 The rotating part 122 has an annular snap-fit ​​groove 1222 on its circumferential surface, and the mounting hole 1211 has an annular snap-fit ​​structure 1212 on its side wall. The snap-fit ​​structure 1212 is fitted into the snap-fit ​​groove 1222 to prevent the rotating part 122 from dislodging from the mounting hole 1211.

[0038] Please refer to Figure 2 The thickness of the second main body piece 121 at the mounting hole 1211 is greater than that of the first main body piece 111, which makes the mounting hole 1211 deeper and the snap-fit ​​structure 1212 thicker, making it less prone to deformation or damage.

[0039] Please refer to Figure 2 and Figure 7 The rotating component 122 is provided with a protrusion 1223. When the first pull tab 11 and the second pull tab 12 are connected, the protrusion 1223 protrudes from the side of the second main body 121 facing away from the first pull tab 11. With the above structure, the rotating component 122 can be rotated by pinching the protrusion 1223, which is convenient for operation.

[0040] Please refer to Figure 7 The protrusion 1223 is truncated cone-shaped. In the radial direction of the rotating part 122, the size of the protrusion 1223 gradually increases from the end near the second main body piece 121 to the end away from the second main body piece 121, making it easy to hold by hand and convenient to operate.

When the first pull tab 11 and the second pull tab 12 are connected, they can fit together, resulting in a simple structure.

[0042] The second main body piece 121 and the first pull piece 11 are made of metal, making them sturdy and durable.

[0043] The rotating part 122 is made of silicone material, which makes it easy to install the rotating part 122 into the mounting hole 1211.

[0044] How to use the rotatable and fixed pull tab assembly 1 of the preferred embodiment of this utility model: When the first pull tab 11 and the second pull tab 12 are separated, pinch the protrusion 1223 and rotate the rotating member 122 at any angle to the first position, pass the locking block 1121 through the through hole 1221, and then pinch the protrusion 1223 and rotate the rotating member 122 at any angle to the second position. The rotating member 122 is clamped between the first main body piece 111 and the locking block 1121, which can fix the first pull tab 11 and the second pull tab 12. Rotate the rotating member 122 at any angle to the first position and pass the locking block 1121 out of the through hole 1221, which can separate the first pull tab 11 and the second pull tab 12.

[0045] This is the method of using the rotating and fixed pull tab assembly 1 of this preferred embodiment.
