Third strut resets, and guide rod is stuck in card slot corresponding thereto, so that hollow pipe is fixed, can so push baby
Vehicle is mobile；When not pushing perambulator mobile, repeat above operation so that guide rod disengaging card slot, swings hollow then up
Pipe, the first drawstring is relaxed, and under the action of the first spring, the first slide bar and brake block reset, so that brake block fixes the
Two wheels are so capable of the lockking perambulator of safe ready so that perambulator can not move.
User holds regulating wheel and rotates forward, so that reel be driven to rotate forward, withdraws the second drawstring, is driven by the second drawstring
Third slide bar moves right, and third sliding sleeve play the guiding role, and third slide bar, which moves right, drives third directional wheel to move right, from
And the first drawstring is pressed to the right, it drives the first slide bar to move up by the first drawstring, stretches the first spring, the first sliding sleeve rises and leads
To effect, the first slide bar, which moves up, drives brake block to move up, and user can move perambulator at this time, when user holds tune
Section is taken turns and is inverted, so that reel be driven to invert, releases the second drawstring, so that third slide bar and third directional wheel reset to the left,
Under the action of the first spring, the first slide bar and brake block reset downwards, move perambulator can not to fix third wheel
It is dynamic, it so can be in the case where not swinging hollow pipe, so that perambulator is mobile or fixed.
Friction can be generated with friction plate when user rotates regulating wheel, the 4th spring leaf has buffer function, and friction plate increases
Big frictional force can so prevent regulating wheel after being rotated toward revolution so that regulating wheel needs biggish power that can just be rotated.
The invention has the benefit that the present invention presses down on pressing plate by user, guide rod is set to be detached from card slot, at this time
User contacts brake block no longer with third wheel to lower swing hollow pipe, by the first drawstring, and perambulator is moved；
User can make the second drawstring pull third slide bar and third directional wheel to the right by rotating regulating wheel, so that first draws
Rope contacts brake block no longer with third wheel, and perambulator is moved, the frictional force of friction plate increase rotation regulating wheel,
So can conveniently, safely perambulator be lockked or be unclamped.
