Preferred as the present invention, described spring fixed seat includes the socket part setting gradually and stop part, described set
Socket part and described buffer spring socket, one end of described buffer spring is offseted with described stop part.
Preferred as the present invention, described limit switch mounting seat and described spring fixed seat all offer threading and lead to
Hole, described threading via hole at least runs through described connecting portion, described socket part and described stop part.
Preferred as the present invention, the internal diameter of the described threading via hole being arranged in described limit switch mounting seat is more than institute
State the external diameter of socket part.This setup effectively improves the largest deformation distance of limiting buffer so that protected effect enters
One step lifting.
Preferred as the present invention, the length of described buffer spring is more than the length of described slip through hole.This set side
Formula buffer spring when limit switch is pressed downward to lowest part still can keep certain elasticity it is ensured that the entering of protected effect
One step lifting.
The invention has the advantages that：
The present invention can protect operator effectively, prevents operator from producing collision with top barrier and producing danger,
Spring in the present invention can carry out certain buffering after limit switch touches top barrier and prevent spacing opening simultaneously
Close the damage inactivation due to the inertia of platform.
