[0033] In the embodiment of the present invention, a group of universal ball wheels 201 are fixedly installed on the front end surface of the pull rod mating block 2 adjacent to the four edge angles; an anti-slip pad 2015 is embedded in the rear end surface of the pull rod mating block 2; when the pull rod mating block 2 is separated from the suitcase 1, the front end surface of the pull rod mating block 2 faces the lower side, and the U-shaped rotating block 204 rotates and unfolds along the T-axis 205, at which time it forms a cart structure.

[0034] The working principle of this embodiment:

[0035] When used in conjunction with the pull rod, the user can grasp the gripping rod 202 to pull and extend the two telescopic rods 203, so that when the luggage 1 is moved, the luggage 1 can be rotated and tilted forward to cooperate with the gripping of the gripping rod 202 and the universal pulley provided at the bottom of the luggage 1 to achieve the moving operation; further, because the pull rod cooperates with the block 2 and the luggage 1 in the installed state, the front and rear end surfaces of the U-shaped rotating block 204 are respectively in contact with the front side surface of the inner end of the storage notch 206 and the front end surface of the luggage 1, so the contact between the U-shaped rotating block 204 and the storage notch 206 is blocked to ensure that the auxiliary moving operation based on the pull rod can be achieved;

[0036] The tie rod matching block 2 of the present application is fixedly installed with the bag 1 through the threaded connection between the stud 2012 and the threaded through hole 102, and the plug-in slot 2011 of the present application adopts a unique elliptical slot structure. Through this structural design, commonly used tools, such as hexagonal wrenches, screwdrivers, etc., cannot be inserted into the plug-in slot 2011 to drive the movable block 2010 and the stud 2012 to rotate, thereby effectively preventing non-user personnel from disassembling the bag 1 and the tie rod matching block 2. The connector 208 of the present application that cooperates with the plug-in slot 2011 structure can be connected to the items carried by the user, such as a key ring, through the ring 209. When the user needs to disassemble the tie rod When the rod matching block 2 is installed with the bag 1, the user can insert the connector 208 through the plug hole 2014 to match the plug slot 2011, and then twist the connector 208 through the ring 209, thereby synchronously driving the movable block 2010 and the stud 2012 to rotate, so that the stud 2012 and the threaded through hole 102 are threadedly rotated and separated, so as to cooperate with the disassembly operation of the rod matching block 2 and the bag 1. The present application uses a detachable rod matching block 2 to replace the traditional integrated rod luggage. Through the detachable split design, the rod no longer occupies the internal space of the bag, so that there is more space in the bag to store and place items.

[0037] The present application can also meet the user's needs for carrying items. When the user carries a large number of items but there is no corresponding transportation tool such as a cart, the user can disassemble the pull rod matching block 2, and then make the front end face of the pull rod matching block 2 face the lower side, and the U-shaped rotating block 204 rotates and unfolds along the T-axis 205, then it will form a cart structure. The user can place the items to be transported on the anti-slip pad 2015 on the rear end face of the pull rod matching block 2, and then grasp the handle 202 to use the universal ball wheel 201 in contact with the ground as a moving auxiliary part to realize the mobile transportation operation to meet the user's needs for carrying items.
