When adapting to the base of the suitcase, the movable frame 12 can be clamped on one side of the suitcase, and the entire base can be clamped directly under the suitcase to play a supporting and buffering role. Under the action of the blocking mechanism 4, the splashing of mud and impurities on the bottom of the suitcase can be reduced. The blocking mechanism 4 is located on one side of the universal wheel, and can block the sewage and mud spots brought up by the universal wheel during the rotation of the universal wheel to reduce the infiltration of sewage at the bottom of the suitcase.

A through groove is provided on the welding shaft 411. The reset plate 42 is arranged inside the through groove. The reset plate 42 is used to block the sludge impurities splashed during the movement of the luggage box. During the installation process, the sliding rod 43 can be adjusted to move according to the specific situation of the luggage box. The reset plate 42 can be deformed by cooperating with the rubber shaft, so that the reset plate 42 can be located directly below the luggage box, and the sludge and mud can be prevented from remaining at the bottom of the luggage box.
[0046] A sliding rod 43 is movably provided on the welding shaft 411, and one end of the sliding rod 43 is fixedly connected to a plurality of rubber shafts, and the rubber shafts are clamped on the reset plate 42. The sliding rod 43 is clamped at the bottom of the support frame 3. When there is too much dirt docked at the bottom of the reset plate 42, the limit on the sliding rod 43 can be released, thereby pushing the sliding rod 43 to move. The elastic rod 45 can drive the reset plate 42 and the blocking shaft 44 to move, and can quickly shake off the sludge and impurities docked at the bottom, which is convenient for cleaning.
[0047] A plurality of compression grooves are provided at the bottom of the reset plate 42, and a plurality of elastic rods 45 are fixedly connected at both ends of the bottom of the reset plate 42.

An air inlet is provided at one end of the expansion tube 46, and the expansion tube 46 can be extended to both ends to push the length of the blocking shaft 44 to change to adapt to suitcases of different sizes. By replenishing air in the expansion tube 46, the position of the blocking shaft 44 is changed, so that its length corresponds to the size of the suitcase, thereby preventing the Oxford cloth layer on the side of the suitcase from adhering to sewage during towing.
[0048] Working principle: first, when adapting to the base of the suitcase, the movable frame 12 can be clamped on one side of the suitcase, and the entire base can be clamped under the suitcase to play a supporting and buffering role. Under the action of the blocking mechanism 4, the sludge impurities and the like can be reduced from splashing on the bottom of the suitcase. The blocking mechanism 4 is located on one side of the universal wheel, and can block the dirt and mud spots brought up by the universal wheel during the rotation of the universal wheel, thereby reducing the situation where sewage seeps into the bottom of the suitcase. During the installation process, the sliding rod 43 can be adjusted to move according to the specific situation of the suitcase, and the rubber shaft can be used to drive the reset plate 42 to deform, so that the reset plate 42 can be located directly under the suitcase, and the dirt and mud can be prevented from remaining at the bottom of the suitcase.
[0049] Then, the expansion tube 46 can be inflated with air in cooperation with an external air pressure device, so that the position of the blocking shaft 44 changes, and its length is relative to the size of the suitcase, so as to prevent the Oxford cloth layer on the side of the suitcase from adhering to the sewage during the towing process. When there is too much dirt docked at the bottom of the reset plate 42, the limit of the sliding rod 43 can be released, thereby pushing the sliding rod 43 to move, and the elastic rod 45 can drive the reset plate 42 and the blocking shaft 44 to move, so that the sludge impurities docked at the bottom can be quickly shaken off, which is convenient for cleaning;
[0050] Finally, during the towing process of the suitcase, the buffer rack 32 can reduce accidents such as bumps. When the buffer rack 32 pushes the buffer rod 36 to deform, it can be squeezed between the compression plate 371 on the arc pressure rod 37, which can play a role in stabilization and shock absorption when impacted, thereby preventing the items inside the suitcase from being damaged due to expansion and the like.
