[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, A reinforced fixing structure for the folding seat of a stair-climbing machine of the present utility model includes a folding component of the folding seat of the stair-climbing machine, and further includes a first L-shaped positioning block 1. A L-shaped vertical groove block 2 is arranged in the middle of the first L-shaped positioning block 1. A second L-shaped positioning block 3 is arranged at the right end of the first L-shaped positioning block 1. The structures of the first L-shaped positioning block 1 and the second L-shaped positioning block 3 are mirror images of each other. Two electric telescopic rods 4 are arranged between the first L-shaped positioning block 1 and the second L-shaped positioning block 3. Each electric telescopic rod 4 is a rechargeable structure, making the electric telescopic rod 4 of this reinforced fixing structure for the folding seat of the stair-climbing machine convenient to use. The two electric telescopic rods 4 are evenly spaced. Each electric telescopic rod 4 cooperates with the first L-shaped positioning block 1 and the second L-shaped positioning block 3 respectively. The cooperation mode between each electric telescopic rod 4 and the first L-shaped positioning block 1 and the second L-shaped positioning block 3 is a fixed cooperation, making the fixation of the two electric telescopic rods 4 with the first L-shaped positioning block 1 and the second L-shaped positioning block 3 more firm. The edges of the first L-shaped positioning block 1, the L-shaped vertical groove block 2, the second L-shaped positioning block 3 and the electric telescopic rod 4 are all rounded, so that this reinforced fixing structure for the folding seat of the stair-climbing machine will not scratch the user during use. This reinforced fixing structure for the folding seat of the stair-climbing machine can play a role in strengthening the folding component of the seat during use, making the safety of the folding seat of the stair-climbing machine better during use.

[0020] In summary, for this reinforced fixing structure for the folding seat of the stair-climbing machine, during use, first place the first L-shaped positioning block 1 and the second L-shaped positioning block 3 at both ends of the folding component of the folding seat of the stair-climbing machine respectively, and turn on the electric telescopic rod 4, so that the two L-shaped vertical groove blocks 2 can clamp both ends of the folding component of the folding seat of the stair-climbing machine respectively. During use, the first L-shaped positioning block 1 and the second L-shaped positioning block 3 will disperse the force on the folding component of the folding seat of the stair-climbing machine, thus playing a strengthening role. This reinforced fixing structure for the folding seat of the stair-climbing machine can play a role in strengthening the folding component of the seat during use, making the safety of the folding seat of the stair-climbing machine better during use, and the use effect of this reinforced fixing structure for the folding seat of the stair-climbing machine is better.
