[0028] Preferably, the side wall of the piston rod 1073 is provided with an integral protrusion 10731, the top of the mounting plate 106 is fixedly provided with a retainer 1061, and the part of the piston rod 1073 with the protrusion 10731 is arranged in the middle of the retainer 1061. Specifically, the retainer 1061 can cooperate with the protrusion 10731 to limit the piston rod 1073, so that the piston rod 1073 can only slide in the axial direction and cannot be randomly rotated.

[0029] Preferably, the middle position of the piston 1075 is provided with a one-way valve 1078, and the edge position of the piston 1075 is provided with an oil discharge hole 1079. Specifically, the one-way valve 1078 is in a one-way conductive state from the side of the piston rod 1073 to the spring 1076, and when the piston rod 1073 pushes the piston 1075 to compress the spring 1076, the internal hydraulic oil can only pass through the small oil discharge hole 1079 to the space at the bottom end of the piston 1075, achieving a buffering effect.

[0030] Preferably, the inside of the bridge 104 is provided with a rotatable rotating shaft 102, and the two ends of the rotating shaft 102 are sleeved with rubber wheels 103. Specifically, the rubber wheels 103 can slide on the ground to realize the function of walking on the ground.

[0031] Preferably, the bottom end edge of the bottom plate 101 is fixedly provided with a brake head 108. Specifically, the brake head 108 is made of PU material and achieves the effect of braking by friction with the ground.

[0032] Preferably, the screw rod 1072 is sleeved with an anti-loosening screw near the upper surface of the mounting plate 106. Specifically, the anti-loosening screw can keep the bottom end of the screw rod 1072 in a predetermined position of the mounting plate 106 without affecting the rotation of the screw rod 1072.

[0033] Preferably, the top end of the support column 105 is welded with a universal ball head 1051, and the bottom of the bottom plate 101 is fixedly provided with a universal ball seat 1052.

[0034] Working principle: when in use, the sole is extended into the shoe body 20 and fixed, and moves with the rubber wheel 103 at the bottom. When braking is needed, the front brake head 108 is rubbed against the ground. When performing a wheel sliding movement, the rubber wheel 103 will generate an impact force with the ground, which is transmitted to the bottom plate 101 and the shoe body 20 through the rotating shaft 102 and the bridge 104. In this process, part of the impact force is transmitted to the screw rod 1072 and the piston rod 1073, thereby forcing the piston 1075 to slide towards the top of the cylinder 1074 and compressing the spring 1076 and the internal hydraulic oil. The spring 1076 and the hydraulic oil serve as a buffer effect. The hydraulic oil will slowly drain into the lower cavity through the oil drain hole 1076, achieving a buffering effect. When the impact force disappears and is not under stress, the spring 1076 releases the elastic potential energy to reset the piston 1075, and the hydraulic oil will also flow into the initial position through the one-way valve 1078. It should be noted that when the user needs to adjust the damping effect according to individual use requirements or use scenarios, they only need to turn the knob 1071 to rotate the screw rod 1072, adjust the distance of the screw rod 1072 extending into the bottom end of the piston rod 1073, and thereby adjust the movement stroke of the piston rod 1073 and the piston 1075, so as to adjust the damping effect.

[0035] It should be noted that in this document, the terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of other identical elements in the process, method, article or equipment including the element.
