Thereby, when the user presses the button 140 toward the opening 115 to adjust the wheel set 120 from the retracted position to the extended position, the button 140 is attracted by the magnetic positioner 117 and is adjusted from the adducted state to the extended state and buckled. In the extended positioning slot 112, the wheel set 120 is stably positioned in the extended position, so that the wheel set 120 extends out of the box 210 to facilitate the inner wheel box 200 to be towed on the road surface. When the user presses the button 140 in the direction of the box 210 to adjust the button 140 to the retracted state, the button 140 will be disengaged from the extending positioning slot 112, so that the wheel set 120 is subjected to the telescopic elastic force of the elastic member 130. The push-in position is adjusted to the adduct position, and the wheel set 120 is received in the box body 210 to prevent the wheel set 120 from being damaged by external force.

In order to make the inner ring wheel box 200 omnidirectionally towed on the road surface and to prevent the wheel set 120 from being damaged by the external force of the road surface, the axle 122 may further include a wheel body fixing member 1221 and a cushioning elastic member 1222. The arrangement of the wheel body fixing member 1221 and the cushioning elastic member 1222 is the same as that of FIGS. 1A to 1E, and will not be further described herein. Thereby, the inner wheel house 200 can be omnidirectionally towed on the road surface through the arrangement of the wheel body fixing member 1221, which can improve the convenience of use of the inner wheel house 200, and when the road surface is bumped, the cushioning elastic member 1222 and the extension The receiving elastic member 130 can buffer the external force from the road surface to avoid damage of the wheel set 120, and further improve the service life and the comfort of the inner ring wheel box 200.

In summary, when the wheel set 120 is positioned in the adduction position, the elongate elastic member 130 is in an uncompressed state and abuts against the seat body 110 and the wheel set 120 to receive the wheel set 120 into the box 210. The wheel set 120 is prevented from being damaged by an external force during the handling process, and the effect of protecting the wheel set 120 is achieved. When the wheel set 120 is positioned in the extended position, the wheel set 120 extends out of the box body 210, and the extending elastic member 130 is in a compressed state to provide the telescopic elastic force of the wheel set 120 of the inner take-up wheel box 200, so that the inner take-up wheel box 200 can be Drag on the road comfortably. Further, by the arrangement of the wheel body fixing member 1221 and the cushioning elastic member 1222, the inner wheel house 200 can be towed to the road surface omnidirectionally and the wheel set 120 can be prevented from being damaged, and the use comfort can be further improved. When the user presses the button 140, the positioning position of the wheel set 120 can be adjusted. In detail, when the wheel set 120 is positioned in the extended position, the extending elastic member 130 and the cushioning elastic member 1222 can buffer an external force from the road surface to prevent the wheel set 120 from being damaged. When the user presses the button 140 toward the box 210, the button 140 can be adjusted from the extended state to the retracted state, the button 140 is disengaged from the extended positioning slot 112, and the wheel set 120 is subjected to the expansion and contraction of the extending elastic member 130. The elastic force is pushed to adjust to the adduct position from the extended position, and the wheel set 120 is received in the box 210 to achieve the effect of protecting the wheel set 120. When the user presses the button 140 toward the opening 115, the button 140 will drive the wheel set 120 to displace in the accommodating groove 111, and adjust the wheel set 120 from the inner receiving position to the extended position, and the button 140 is subjected to the magnetic positioner 117. The attracting or positioning elastic member 118 is pushed against and adjusted from the adducted state to the extended state, and is snapped into the extended positioning groove 112 to stably position the wheel set 120 in the extended position, so that the wheel set 120 extends out of the box. 210, and in turn, the inner wheel box 200 can be towed omnidirectionally on the road surface.
