Referring to fig. 13, the frame of the roller skate frame may be configured to have arc-shaped processing structures at both ends.

The roller skate rack is arranged at the shoe bottom, and when the roller skating function is needed, the assembly of the rollers 3-3 is unfolded to extend out of the rack 1 to walk in a roller skating way; the pulley 3-3 assembly is folded to be hidden in the frame 1 for normal walking without the pulley function during normal walking.

The specific folding and unfolding principle of the pulley 3-3 assembly is as follows:

as shown in the figure, when the pulley 3-3 assembly is folded into the rack 1, the knob 5 is rotated to enable the control connecting rod 4-3 to act, the control connecting rod 4-3 drives the control limiting component 4-1 to move, namely the central plate 4-32 of the control connecting rod 4-3 rotates, the connecting rod one 4-31 and the connecting rod two 4-33 move inwards oppositely, the control limiting component 4-1 on the left side moves rightwards under the drive of the connecting rod one 4-31 and the connecting rod two 4-33, the control limiting component 4-1 on the right side moves leftwards, after moving for a certain distance, the control limiting component 4-1 does not clamp the linkage shaft one 3-2 and the linkage shaft two 3-5 any more, and at the moment, the pressure spring 4-2 is in a compressed state; then a user pushes the pulley 3-3 upwards by hands, the pulley 3-3 drives the support short sheet 3-1 and the support long plate to rotate around the rack 1 respectively, the support short sheet 3-1 rotates to drive the linkage shaft I3-2 to move upwards, the support long plate 3-4 rotates to drive the linkage shaft II 3-5 to move upwards, the pulley 3-3 is just folded in the rack 1 when the linkage shaft I3-2 and the linkage shaft II 3-5 move upwards to the upper part of the chute, and the tension spring 3-6 is in a stretching state at the moment; in order to prevent the tension spring 3-6 from pulling the second linkage shaft 3-5 to move downwards, the first linkage shaft 3-2 and the second linkage shaft 3-5 are clamped by the limiting component 4-1 again after moving to the upper part of the chute, namely the knob 5 is loosened, the limiting component 4-1 is controlled to move outwards under the action of the elastic force of the tension spring 4-2, and the first linkage shaft 3-2 and the second linkage shaft 3-5 are locked to prevent the first linkage shaft 3-2 and the second linkage shaft 3-5 from sliding downwards;

when the pulley 3-3 assembly is unfolded from a folded state, the knob 5 is rotated again to control the connecting rod 4-3 to act, the limiting component 4-1 is controlled to move to lose the limiting on the first linkage shaft 3-2 and the second linkage shaft, the second linkage shaft 3-5 moves downwards under the action of the tension spring 3-6, the first linkage shaft 3-2 and the second linkage shaft 3-5 act simultaneously through the linkage piece 3-7, the pulley 3-3 assembly is unfolded in the rack 1 at the moment, after the knob 5 is loosened, the connecting rod 4-3 is controlled to move outwards under the action of the pressure spring 4-2, the first linkage shaft 3-2 and the second linkage shaft 3-5 are clamped at the lower part of the sliding chute, and at the moment, the pulley 3-3 is in an unfolded state.
