[0003] For example, the patent with announcement number CN220607667U discloses a portable travel bag, including a travel bag body, which includes handles and shoulder straps, and the handles are located on both sides of the travel bag body. When the pull rod is needed to pull the travel bag body, the pull rod is first pulled out of the fixed base. When the pull rod is pulled out, the limit blocks on both sides of the pull rod are inserted into the limit grooves on both sides of the fixed base, and the top block A at the bottom end of the center position of the rear end of the pull rod squeezes the top block B at the upper end of the connecting rod, so that the connecting rod is squeezed and lowered while the roller extends out of the outside of the through groove, so that the travel bag can be pulled like a suitcase through the pull rod and the roller. When the pull rod is not needed, the limit blocks on both sides of the fixed base are squeezed, and the limit blocks are retracted to the inside of the pull rod. The connecting rod is reset by squeezing the pull rod through the spring A, and the roller is retracted into the through groove, thereby preventing the travel bag body from sliding when it is placed on the ground.
