The scheme is realized by the following technical means:

example (b): in elevator installations, in order to prevent objects from getting stuck in the entrance of the steps, the surface of the elevator steps is usually made as a grooved structure, and a comb plate with teeth corresponding to the grooved structure is fixedly mounted on the upper side of the elevator steps. As the comb tooth support plate 1 erected on the upper side of the elevator pedal for mounting the comb plate, an anti-slip plate for increasing the friction force of passengers stepping on the upper side to avoid slipping is also generally mounted on the upper surface of the comb tooth support plate. In the process of transporting goods or passengers, the elevator equipment can generate an impact acting force along the horizontal direction when transferred to the comb tooth supporting plate 1 because the passengers or the goods in the initial state are borne by the forward moving elevator pedals. If the connecting structure of the comb tooth supporting plate 1 is set to be rigid, the damage and displacement of parts can be caused after the comb tooth supporting plate is used for a period of time, and the safety of equipment and the running stability are seriously influenced.

Therefore, the utility model designs a horizontal positioning and connecting structure 10 of the comb tooth supporting plate between the comb tooth support and the substrate 2 as the bearing part of the comb tooth support, which not only solves the problems, but also ensures that the positions of all parts are accurate and reliable under the condition of long-time operation.
