[0039] In the process, when the resistance card 104 is installed and locked, first rotate the fixed disc 209, and then drive the rotating rod 204 to rotate, while the rotating rod 204 rotates, and drive the reset torsional spring 210 to produce torsional deformation;

[0040] At the same time, the rotating disc 205 is driven to rotate while the rotating rod 204 rotates, and during the rotation of the rotating disc 205, the arc-shaped sliding groove 207 formed in the rotating disc 205 moves on the sliding pin 206, at this time the sliding pin 206 moves in the direction of approaching each other according to the track of the arc-shaped sliding groove 207, and the sliding pin 206 slides in the moving slot 208 formed in the plug pin 201, while the sliding pin 206 drives the blocking block 202 to move, and the blocking block 202 compresses the spring 203 at the same time, until the blocking block 202 is completely moved to the inside of the plug pin 201;

[0041] At the same time, the plug pin 201 corresponds to the through hole of the support pipe 101, and after the resistance card 104 is clamped in the support pipe 101, part of the plug pin 201 passes through the through hole and is located in the inside of the support pipe 101, then the fixed disc 209 is loosened, at this time the rotating rod 204 is driven to reset under the torsional reset of the reset torsional spring 210, and then drives the rotating disc 205 to rotate and reset, at this time the two groups of sliding pins 206 move away from each other, and the spring 203 rebounds to partially extend the blocking block 202 from the plug pin 201, and the bottom of the blocking block 202 is attached to the inner wall of the support pipe 101, the overall size of the two groups of extended blocking blocks 202 and the plug pin 201 is greater than the size of the through hole, so that the resistance card 104 can be installed on the support pipe 101, and the arc-shaped structure of the resistance card 104 is clamped on the support pipe 101, thereby improving the stability of the resistance card 104 installation.

[0042] Further more;

[0043] In an optional embodiment, a reinforcing plate 105 is integrally arranged at the surface center of the resistance card 104.

[0044] In this embodiment: the reinforcing plate 105 arranged on the arc surface of the resistance card 104 can increase the strength of the resistance card 104, avoid deformation of the resistance card 104, make the arc-shaped socket larger, and further improve the clamping effect of the resistance card 104.

[0045] The working principle and use process of the utility model are as follows: when using the stair walker with a limit structure, the interference clamp 104 is an arc-shaped structure, which can be clamped on the surface of the bracket tube 101 to limit the interference of the shell cover 102; in this process, when installing and locking the interference clamp 104, the fixing plate 209 is first rotated, thereby driving the rotating rod 204 to rotate. When the rotating rod 204 rotates, it also drives the return torsion spring 210 to generate torsional deformation; As the rotating rod 204 rotates, the rotating disk 205 is also driven to rotate. During the rotation of the rotating disk 205, the arc-shaped slot 207 provided on the rotating disk 205 moves on the sliding pin 206. At this time, the sliding pin 206 moves in the direction of approaching each other according to the trajectory of the arc-shaped slot 207. The sliding pin 206 slides in the moving slot 208 provided by the latch 201. At the same time, the sliding pin 206 drives the blocking block 202 to move. At the same time, the blocking block 20 2 and compress the spring 203 until the blocking block 202 is completely moved to the inside of the latch 201; at the same time, the latch 201 is aligned with the through hole of the bracket tube 101, and after the abutting clamp 104 is stuck in the position of the bracket tube 101, the latch 201 partially passes through the through hole and is located inside the bracket tube 101, and then the fixed disk 209 is released. At this time, under the torsion reset of the reset torsion spring 210, the rotating rod 204 is driven to reset, and then the rotating disk 205 is driven to rotate and reset. At this time, the two groups The sliding pins 206 move away from each other, and at the same time the spring 203 rebounds, which can extend the blocking block 202 partially from the latch 201, and the bottom of the blocking block 202 fits against the inner wall of the bracket tube 101. The overall size of the two groups of extended blocking blocks 202 and the latch 201 is larger than the size of the through hole, so that the interference clamp 104 can be installed on the bracket tube 101, and the arc structure of the interference clamp 104 is stuck on the bracket tube 101, thereby improving the stability of the installation of the interference clamp 104.
