A limiting groove is opened in the middle of the other end of the corrugated storage box (6). The limiting groove and the other end of the auxiliary fixed shaft (19) are correspondingly engaged. A friction pad is placed on the outer wall of the guide ring.

[0020] In use, in the initial state, the pin (4) passes through the auxiliary fixing ear (5) and is inserted into the insertion hole (15) located at the outermost end of the crossbar (14). The slide bar (17) is folded and stored inside the rotating tube (16). The rotating tube (16) is stored inside the storage slot (2). The pull handle (1) is correspondingly engaged inside the notch (3).

[0021] When the suitcase needs to be pulled, take the handle (1) out of the slot (3) and the rotating tube (16) out of the storage slot (2). Then pull the handle (1) so that the handle (1) pulls the slide bar (17) out of the fixed tube against the spring stress of the internal spring. Pull the slide bar (17) and the rotating tube (16) by the handle (1), thereby driving the crossbar (14) to move. The main guide ring on the main roller (7) and the auxiliary guide ring on the auxiliary roller (21) rub against the ground, thereby driving the corrugated storage box (6) to rotate. At this time, since there is a bearing between the main guide ring and the main fixed ring (11) and a bearing between the auxiliary guide ring and the auxiliary fixed ring (18), the main fixed ring (11) and the auxiliary fixed ring (18) remain stable, thereby making the crossbar (14) stable, so that the suitcase can be pulled normally.

[0022] When the width of the suitcase needs to be adjusted, the pin (4) is taken out from the hole (15) at the outermost end of the crossbar (14). At this time, the other end of the crossbar (14) is separated from the auxiliary fixing ear (5) on the auxiliary fixing ring (18). Then, the auxiliary roller (21) is pressed by the reinforcing plate (22) on the auxiliary fixing ring (18), thereby pressing the corrugated storage box (6) and causing the corrugated storage box (6) to shrink accordingly. After shrinking to the appropriate width, the pin (4) is inserted through the auxiliary fixing ear (5) and placed inside the corresponding hole (15), so that the other end of the crossbar (14) and the auxiliary fixing ear (5) on the auxiliary fixing ring (18) are connected again, thereby adjusting the width of the suitcase.

[0023] When the suitcase needs to be folded and stored, remove the pin (4) from the outermost insertion hole (15) at one end of the crossbar (14). At this time, the other end of the crossbar (14) separates from the auxiliary fixing ear (5) on the auxiliary fixing ring (18). Then release the handle (1), so that the handle (1) is reset under the action of the slide bar (17). Place the handle (1) inside the notch (3), and place the rotating tube (16) inside the storage slot (2). Then rotate the crossbar (14) so ​​that the crossbar (14) rotates around the connecting shaft (13) at one end until it rotates to the main fixing ring (18). 1) On the connecting plate (9), the middle part of the crossbar (14) is correspondingly engaged between the two clamps (10). The insertion hole (15) at one end of the crossbar (14) corresponds to the connecting hole on the lock seat (8). Then, the pin (4) passes through the connecting hole and the insertion hole (15) at one end of the crossbar (14) to fix the crossbar (14). Then, the reinforcing plate (22) on the auxiliary fixing ring (18) presses the auxiliary roller (21) to press the corrugated storage box (6), so that the corrugated storage box (6) shrinks accordingly, thereby folding and storing the suitcase.

[0024] The design of having a friction pad on the outer wall of the main roller (7), the auxiliary roller (21) and the ground can increase the friction between them and prevent the suitcase from slipping when being pulled.

[0025] The U-shaped longitudinal section of the notch (3) allows the handle (1) to be fully engaged at the bottom of the notch (3), preventing the handle (1) from coming off.

[0026] The slide rod (17) is placed inside the rotating tube (16), and a spring is placed between it and the inner wall of the rotating tube (16). The spring stress of the spring allows the slide rod (17) to be folded and stored inside the rotating tube (16), avoiding taking up extra space. At the same time, the spring stress of the spring can indirectly increase the length of the rotating tube (16), making it more convenient to use.

[0027] The design of the rotating tube (16) having a length equal to the length of the storage slot (2) allows the storage slot (2) and the rotating tube (16) to fit together, thereby storing the rotating tube (16).

[0028] The design that the vertical distance between the two clamping plates (10) and the width of the crossbar (14) are equal enables the two clamping plates (10) to cooperate in clamping and storing the crossbar (14);

[0029] The middle part of the clamp (10) is inwardly contracted. The clamp (10) is made of rubber material, which makes the middle part of the clamp (10) elastic, thereby further clamping the crossbar (14) and preventing the crossbar (14) from coming off.

[0030] The design of the lock seat (8), clamping plate (10) and main fixing ear (20) being collinear enables the middle part of the crossbar (14) to correspond to the clamping plate (10) and one end of the crossbar (14) to correspond to the lock seat (8), thereby clamping the crossbar (14) a second time.

[0031] The outer wall of the corrugated storage box (6) is equipped with a zipper, which allows the corrugated storage box (6) to be opened and closed, making it convenient to use;

[0032] The design of the other end of the pin (4) being bent away from the crossbar (14) makes it easier for the staff to hold the pin (4) and makes it more convenient to use.

[0033] The pin (4) and the insertion hole (15) on the crossbar (14) cooperate to fix the width of the corrugated storage box (6). The corrugated storage box (6) can be compressed to different degrees according to different usage needs. The pin (4) is used to connect the auxiliary fixing ear (5) and the corresponding insertion hole (15) on the crossbar (14). In this way, the size of the internal space of the suitcase can be changed according to the amount of items carried, avoiding excessive waste of space.

[0034] The design of the clamping plate (10) and the lock seat (8) engaging the crossbar (14) allows the crossbar (14) to rotate through the connecting shaft (13) and the main fixing ear (20), and then the clamping plate (10) and the lock seat (8) engage and fix the crossbar (14) again. At the same time, the corrugated storage box (6) is used to shrink and fold in multiple directions for storage. When folded, it occupies little space and is easy to store.

[0035] The corrugated storage box (6) can be used to fold the space of the suitcase. The space of the corrugated storage box (6) can be fixed by the pin (4) in conjunction with the hole (15) and auxiliary fixing ear (5) on the crossbar (14). At the same time, it can be used with the clamp (10) and lock seat (8) to fold and lock the crossbar (14) for multi-directional folding and storage. The space occupied during folding and storage is small, which is convenient for storage.
