Button, it is placed in described the first blind hole and is connected with described bar handle moving sets;
Elastic element, it is fixedly connected with described bar handle with described button respectively along described button moving direction;
Pull bar, it is placed in described the second blind hole and is connected with described bar handle moving sets;
Joystick, it is connected with described pull bar, and it has latch;
Described button has the fitting surface that supports described pull bar and coordinate with described pull bar, and when described button compresses described elastic element, described pull bar moves and will carry on described latch along described the second blind hole.
Selectable, described the first blind hole and described the second blind hole quadrature, described fitting surface is dip plane, and described pull bar has the antifriction-bearing box coordinated with described fitting surface, and described antifriction-bearing box can be along described fitting surface scroll-up/down.
Selectable, described the first blind hole and described the second blind hole quadrature, described fitting surface is dip plane, and described pull bar has the second fitting surface coordinated with described fitting surface, and described the second fitting surface and described fitting surface fit.
Selectable, the two ends of described fitting surface have positioning plate.
Selectable, described elastic element is spring.
Selectable, described button outer end has button cap.
The beneficial effects of the utility model:
Hold bar handle by palm and can remove parking lock by the thumb applying light, external form, radian, button force and stroke all can carry out design modifying according to client's feel demand; New construction is stronger from the sense of external form science and technology simultaneously, and structure realizes uncomplicated, can be widely used in the exploitation of all kinds of gas braking vehicle hand control valve (HCV)s; Adopt antifriction-bearing box to coordinate with fitting surface, force of rolling friction is less than force of sliding friction, and the motion of button more easily drives the pull bar motion, moves more smooth; Adopt the second fitting surface and fitting surface, guarantee enough area of contact, move more stable.
