The utility model is set to further: described containment vessel offers the gathering sill for pressing piece slippage, described gathering sill and mutually UNICOM identical with containing cavity setting direction.
By adopting technique scheme, the setting party of gathering sill the connection of pressure head and pressing piece, also facilitate pressing piece interlock pressure head pressing back-moving spring, pressure head is positioned at containment vessel and better contacts with back-moving spring, the movement of guarantee pressure head in containment vessel.
The utility model is set to further: described pressing piece is provided with the hollow-out parts for containment vessel slippage towards containment vessel side, described hollow-out parts along the length in back-moving spring direction and described gathering sill length suitable.
By adopting technique scheme; arranging of hollow-out parts can make containment vessel overlapping with the skidding distance of pressing piece; for pressing piece slippage on containment vessel; save the space that reset assembly is positioned at the motion of button pedestal; both length is suitable, defines the displacement of pressing piece, can only move in gathering sill length; make pressing piece that moving contact can not be driven to outside yield limit, protect moving contact and back-moving spring.
The utility model is set to further: described containing cavity and pressure head suitable and in circular.
By adopting technique scheme, containing cavity inwall be circular be arranged on inner back-moving spring external diameter and match, even if when back-moving spring generation deformation, both smooth contact and by inwall restriction in vertically, guarantee back-moving spring radial deformation does not occur.
The utility model is set to further: described pressure head and pressing piece removably connect.
By adopting technique scheme, pressing piece and pressure head are detachable, facilitate pressure head to embed in containment vessel, can prevent when installing pressure head and pressing piece be integrally can not sheathed enter situation in containment vessel occur.
