[0032] 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.

[0033] See also Figure 1-Figure 5 As shown, a fully biodegradable shopping bag with a tightenable bag opening comprises a shopping bag body 1 and a drawstring 11 with two ends sewn to the middle position of the top of the shopping bag body 1;

[0034] An elliptical block 2 is arranged on the outer side of the middle of the pull rope 11; a pressure block 21 is slidably connected to the middle of the elliptical block 2; a symmetrically arranged No. 1 circular hole 22 and a No. 2 circular hole 23 are respectively opened at the corresponding positions of the elliptical block 2 and the pressure block 21, and the pull rope 11 is located between the No. 1 circular hole 22 and the No. 2 circular hole 23; a No. 1 spring 24 is fixedly connected to the middle of the lower surface of the pressure block 21, and the other end of the No. 1 spring 24 is fixedly connected to the elliptical block 2.

[0035] During operation, after putting items into the shopping bag body 1, when the bag opening needs to be tightened, the user holds the inside of the two U-shaped rubber blocks 4 with both hands respectively, and then lifts the U-shaped rubber blocks 4 upward to make the shopping bag body 1 rise. Under the gravity of the items inside the shopping bag body 1, the drawstring 11 moves out from the top of the shopping bag body 1 to tighten the bag opening of the shopping bag body 1. When the weight of the items inside the shopping bag body 1 is not enough to tighten the bag opening of the shopping bag body 1, the user pulls the U-shaped rubber block 4 outward with one hand and holds the shopping bag body steady with the other hand. The two drawstrings 11 are respectively moved out from the top of the shopping bag body 1, so that the bag opening of the shopping bag body 1 is tightened. After the bag opening of the shopping bag body 1 is tightened, the user picks up the two oval blocks 2 respectively and presses the pressing block 21 in the middle of the oval block 2, so that the pressing block 21 slides into the inside of the oval block 2. After the pressing block 21 enters the inside of the oval block 2, the first round hole 22 overlaps with the second round hole 23, so that the drawstring 11 is no longer clamped. At this time, the drawstring 11 is straightened and the oval block 2 is moved to a position close to the bag opening of the shopping bag body 1, because when the pressing block 21 is pressed, , the pressing block 21 slides into the oval block 2, squeezing the No. 1 spring 24. The No. 1 spring 24 will shrink under the squeezing and give a thrust to the pressing block 21. Therefore, after the oval block 2 is moved, the pressing block 21 is slowly released. Under the thrust of the No. 1 spring 24, the pressing block 21 is reset, so that the No. 1 round hole 22 and the No. 2 round hole 23 no longer overlap. Under the action of the No. 1 spring 24, the pressing block 21 and the oval block 2 will cooperate with each other to squeeze the drawstring 11, fix the drawstring 11, and thus fix the bag mouth of the shopping bag body 1. When the shopping bag body 1 is transported with the items packed in it, the opening of the shopping bag body 1 can be prevented from opening due to vibration. When the items in the shopping bag body 1 need to be taken out, the user can take the two oval blocks 2 with both hands at the same time and press the pressing block 21 to make the drawstring 11 lose its fixation. After the drawstring 11 loses its fixation, the two oval blocks 2 are moved upward at the same time to make the oval blocks 2 away from the opening of the shopping bag body 1. Then, the user can put both hands into the opening of the shopping bag body 1 and spread the opening of the shopping bag body 1 outward to take the items out of the shopping bag body 1.

[0036] The shopping bag body 1 is in the shape of a rectangular parallelepiped, and the top of the shopping bag body 1 is open.

[0037] During operation, the purchased articles can be put into the shopping bag body 1 through the opening of the shopping bag body 1 .

[0038] The two ends of the drawstring 11 are sewn to the two long sides of the top of the shopping bag body 1 respectively; the middle part of the drawstring 11 is located in the middle part of the short side of the shopping bag body 1 .

[0039] During operation, by arranging the middle portion of the drawstring 11 at the middle portion of the short side of the shopping bag body 1 , it is more convenient to tighten the opening of the shopping bag body 1 .

[0040] A U-shaped rubber block 4 is sewn to the middle of the pull rope 11 , and four finger-shaped grooves 41 are formed inside the U-shaped rubber block 4 .

[0041] During operation, by additionally adding the U-shaped rubber block 4, when the shopping bag body 1 needs to be picked up, the user can hold the inside of the U-shaped rubber block 4 to lift the shopping bag body 1. The U-shaped rubber block 4 can protect the user's fingers and prevent the user from directly picking up the drawstring 11 when the shopping bag body 1 is heavy, thereby preventing the fingers from being strangled. The finger grooves 41 provided in the U-shaped rubber block 4 can fit the user's fingers, so that the user can be more comfortable when picking up the shopping bag body 1.

[0042] A symmetrically arranged connecting piece 3 is adhered to the outer side of the shopping bag body 1; an arc-shaped No. 1 sleeve 31 and a No. 2 sleeve 32 are fixedly connected to the other side of the connecting piece 3; an arc-shaped insertion rod 33 is slidably connected inside the No. 1 sleeve 31 and the No. 2 sleeve 32; a No. 2 spring 34 is arranged in the No. 1 sleeve 31, and both ends of the No. 2 spring 34 are fixedly connected to the insertion rod 33 and the connecting piece 3; a shift block 35 is fixedly connected to the outer side of the insertion rod 33.

[0043] During operation, after the opening of the shopping bag body 1 is tightened, the user pulls the two shifting blocks 35 respectively to make one end of the insertion rod 33 slide into the No. 1 sleeve 31 and the other end slide out of the No. 2 sleeve 32, thereby creating a gap between the insertion rod 33 and the No. 2 sleeve 32. The user takes the middle part of the drawstring 11 and puts the drawstring 11 between the No. 1 sleeve 31 and the No. 2 sleeve 32 along the gap. Because when the insertion rod 33 slides into the interior of the No. 1 sleeve 31, the No. 2 spring 34 is squeezed, and the No. 2 spring 34 is squeezed and contracts, and a thrust is given to the insertion rod 33, so when After the pull rope 11 is placed, slowly release the shift block 35. Under the thrust of the No. 2 spring 34, one end of the insertion rod 33 slowly slides out of the No. 1 sleeve 31. At the same time, the other end of the insertion rod 33 slides into the No. 2 sleeve 32. A seal is formed between the No. 1 sleeve 31, the insertion rod 33 and the No. 2 sleeve 32, so that the pull rope 11 can be positioned to prevent the pull rope 11 from falling off. At the same time, after the two pull ropes 11 are positioned, the two pull ropes 11 are in a relatively straight state and away from each other, thereby preventing the pull ropes 11 from being entangled with each other and avoiding the trouble of disassembling the pull ropes 11.

[0044] The connecting piece 3 is located in the middle below the short side of the shopping bag body 1 .

[0045] During operation, the connecting piece 3 is adhered to the middle part below the short side of the shopping bag body 1 so that the first sleeve 31, the second sleeve 32 and the insertion rod 33 can correspond to the middle part of the pull rope 11, so that it is more convenient to fix the pull rope 11.

[0046] An end of the insert rod 33 close to the second sleeve 32 is provided with an arc surface 36 .

[0047] During operation, the arc surface 36 provided on the insertion rod 33 allows the insertion of the insertion rod 33 into the second sleeve 32 to be smoother, thereby avoiding the situation where the insertion rod 33 cannot be inserted into the second sleeve 32 due to misalignment.
