The buffer contacts and buffers with the elevator car, so as to prevent the people inside the elevator car from being injured.
[0003] When using the buffer to buffer the elevator car, after the buffer contacts with the elevator car, the impact force generated by the collision between the buffer and the elevator car will cause violent shaking inside the elevator car. Therefore, it is easy to cause the people inside the elevator car to be unstable when standing, and thus easy to cause the people to fall and get injured.
[0004] Therefore, a device for reducing the impact force needs to be designed. Content of the Utility Model

[0036] Instructions for use:
[0037] When using the elevator car body 1, when a failure occurs in the elevator car body 1, the elevator car body 1 will rapidly descend.

By the support plate 302 contacting the protective plate 301, the protective plate 301 can be positioned. By the protrusion 305 engaging with the slot 303, the anti-slip pad 304 can be installed on the protective plate 301, thereby enabling hidden protection of the protective plate 301. Moreover, through the convex slot 303, inserting a finger into the slot 303 facilitates the removal of the protective plate 301.
