The relative quiet board motion of movable plate produces collision each other and can produce noise scheduling problem because can set up the shock pad between quiet board and movable plate, but uses the shock pad for a long time and can wear and tear, consequently need change the shock pad, need dismantle its whole when original stopper is changed the shock pad, and is very inconvenient, through seting up the spout at quiet board lateral part, installs the shock absorber support of shock pad rather than the sliding connection, then makes things convenient for the change to the shock pad greatly.

Further spout one end is the blind end, shock absorber support one end passes through the magnetite actuation with the spout blind end. The magnet is attracted to facilitate the damping support to be fixed in the sliding groove, and the damping support is not easy to slide when the movable plate moves relative to the static plate to generate mutual collision.

And a threaded hole is formed in the other end of the damping support. The damping support is attracted to the sliding groove of the static plate through the magnet and is not easy to slide and detach, and the damping support can be conveniently slid and detached through the drawing bolt at the threaded hole connecting bolt.

To sum up, the utility model provides a brake release mechanism simple structure, simple to operate and conveniently change the elevator stopper of shock pad.
