[0006] As a preferred solution of the present invention: the child Velcro is a Velcro hook surface, and the mother Velcro is a Velcro fleece surface.

[0007] As a preferred solution of the present invention: drawstrings are provided on both sides of the outer wall of the bag body, and the drawstrings can pass through the first opening and the second opening.

[0008] As a preferred solution of the present invention, the fixing piece is adjustable in three gears, and when the hanging ring is located at the uppermost fixing piece, the bottom of the extended bag is flush with the bottom of the bag body.

[0009] As a preferred solution of the present invention: a hollow rectangular frame is provided at the bottom of the bag body, and the inner diameter of the hollow rectangular frame matches the outer diameter of the extension bag.

[0010] As a preferred solution of the present invention: the limiting block is located on the inner wall of the hollow rectangular frame at the bottom of the bag body, and the outer diameter of the limiting block matches the inner diameter of the limiting groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention achieves sealing of the top opening of the bag body by adding a sub-Velcro, a mother Velcro, and a top cover, effectively reducing the situation where the top opening of the traditional bag body is easily stolen by others when it is opened, and also reducing the situation where items inside the bag body fall out from the inside during bumps. Through the mutual cooperation of the extension bag, the limiting groove, the limiting block, the hanging ring, and the fixing parts, it is convenient for the user to adjust the storage capacity of the bag body according to the number of items to be stored, avoiding the situation where the capacity of the traditional bag body is fixed and cannot be adjusted, and multiple sets of bags need to be carried. In addition, the use of the limiting block and the limiting groove allows the outer wall of the extension bag to always be in contact with the bottom opening of the bag body, avoiding the formation of a gap between the extension bag and the bottom of the bag body when extended, causing the internal items to fall.
