[0008] Preferably, the extending groove is circular and arranged inside the bag body, and the extending groove passes through the outer wall of the bag body, and the contraction device is fixedly connected to the inner wall of the extending groove and will not fall off.

[0009] Preferably, the connecting groove passes through the connecting block, and the left pull rope passes through the connecting groove and the extending port to be connected to the connecting block, and the right pull rope directly passes through the extending port to be connected to the retracting device.

[0010] Preferably, the left pull rope and the right pull rope are provided as one rope, and the left pull rope and the right pull rope are just two different ends of one rope.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model is used, the left draw rope is passed through the extending opening and the connecting groove and tied to the connecting block, and the right draw rope is passed through the extending opening and directly tied to the contraction device. When the weight in the bag body becomes heavier, the winding spring mechanism unwinds, so that the connecting block extends from the extending opening, extending the length of the left draw rope and making the rope body longer. When the bag body and the product therein are lighter, the winding spring mechanism rewinds, and the left draw rope is pulled into the contraction device, which can keep the rope body shortened. The overall device is convenient for changing the length of the draw rope according to the change of the bag body weight, and is convenient for adjusting the length.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2The utility model provides a technical solution: a gift bag with adjustable drawstring length, comprising a bag body 1, a stretching slot 2 is provided inside the bag body 1, a contraction device 3 is slidably installed inside the stretching slot 2, a coiling spring mechanism 4 is provided inside the contraction device 3, a connecting block 5 is fixedly installed at one end of the coiling spring mechanism 4, a connecting slot 6 is provided on the side of the connecting block 5, a stretching port 7 is provided on the outer wall of the contraction device 3, a left drawstring 8 is fixedly connected inside the connecting slot 6, and a right drawstring 9 is fixedly connected inside the stretching port 7. In this embodiment, when the left drawstring 8 and the coiling spring mechanism 4 are extended, the right drawstring 9 can be pulled to drive the contraction device 3 to move in the direction of the right drawstring 9, so as to keep the balance of the bag body 1 and prevent the bag body 1 from tilting.

[0020] Preferably, the extension groove 2 is circular and arranged inside the bag body 1, and the extension groove 2 passes through the outer wall of the bag body 1, and the contraction device 3 is fixedly connected to the inner wall of the extension groove 2 and will not fall off. In this embodiment, the extension groove 2 keeps the contraction device 3 able to move in the bag body 1, and the contraction device 3 will not fall out of the extension groove 2. The contraction device 3 has been placed in the bag making process, and the outer side area of ​​the extension groove 2 is smaller than the side area of ​​the contraction device 3, so that the contraction device 3 cannot fall out.

[0021] Preferably, the connecting groove 6 passes through the connecting block 5, and the left pull rope 8 passes through the connecting groove 6 and the extension port 7 to be connected to the connecting block 5, and the right pull rope 9 directly passes through the extension port 7 to be connected to the retraction device 3. In this embodiment, the connecting block 5 is made of plastic and has a certain deformation ability. It is not easy to cause damage to the spring mechanism 4 and the like due to a large collision. When the weight of the bag body 1 is large, the connecting block 5 is pulled by the left pull rope 8 to be discharged from the extension port 7; because the side area of ​​the extension port 7 is larger than the side area of ​​the connecting block 5, when the weight of the bag body 1 becomes lighter, the spring mechanism 4 retracts the connecting block 5 and the left pull rope 8 into the retraction device 3.

[0022] Preferably, the left pull rope 8 and the right pull rope 9 are provided as one piece, and the left pull rope 8 and the right pull rope 9 are just two different ends of one rope. In this embodiment, by connecting the left pull rope 8 and the right pull rope 9 separately, the total length of the rope can be extended or shortened.

[0023] A specific application of this embodiment is:

[0024] The left drawstring 8 is passed through the extension port 7 and the connecting groove 6 and tied to the connecting block 5, and the right drawstring 9 is passed through the extension port 7 and directly tied to the contraction device 3. When the weight in the bag body 1 becomes larger, the winding spring mechanism 4 is unwound, so that the connecting block 5 extends from the extension port 7, extending the length of the left drawstring 8 and making the rope body longer; when the bag body 1 and the product therein are lighter in weight, the winding spring mechanism 4 is wound up and the left drawstring 8 is pulled into the contraction device 3.

[0025] In summary, through the structures such as the retraction device 3, the winding spring mechanism 4, the connecting block 5, the extension port 7, the left pull rope 8 and the right pull rope 9, the overall device can facilitate the change of the pull rope length according to the change of the weight of the bag body 1, thereby facilitating the adjustment of the length.
