Both schemes can realize the fixation between the guide rail strip and the shockproof block.

The hooking end of the transverse pull plate is hooked with the slope on one side of the guide rail strip 2 on the inner side of the shockproof block 101 to form a hooking and limiting position, and is in sliding cooperation with the length direction of the guide rail strip. The guide rail strip is provided with limiting blocks 202 on both sides to limit the sliding of the transverse pull plate, or the above-mentioned bolt 7 at both ends of the guide rail strip is exposed relative to the guide rail strip to limit the sliding of the transverse pull plate.
