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.

Heart handle 1120 drives the first slide bar 6 to move up to lower swing hollow pipe 116, by the first drawstring 10, and the first spring 8 is pressed
Contracting, the first directional wheel 114 and the first sliding sleeve 5 play the guiding role, and the first slide bar 6, which moves up, drives brake block 9 to move up, such as
This user can push perambulator mobile, when user is swung up hollow pipe 116 and no longer pressing pressing plate 1122, second
Under the action of spring 1110, guide rod 118 and third strut 1112 reset, and guide rod 118 is stuck in card slot corresponding thereto
In 1111, so that hollow pipe 116 is fixed, it can so push perambulator mobile;When not pushing perambulator mobile, repeat
The above operation swings hollow pipe 116 so that guide rod 118 is detached from card slot 1111 then up, and the first drawstring 10 is relaxed, the
Under the action of one spring 8, the first slide bar 6 and brake block 9 reset, so that brake block 9 fixes the second wheel 3, so that perambulator
It can not move, so be capable of the lockking perambulator of safe ready.
User holds regulating wheel 22 and rotates forward, so that reel 23 be driven to rotate forward, withdraws the second drawstring 19, draws by second
19 drive third slide bar 17 of rope moves right, and third sliding sleeve 15 play the guiding role, and third slide bar 17, which moves right, drives third fixed
It moves right to wheel 18, to press the first drawstring 10 to the right, drives the first slide bar 6 to move up by the first drawstring 10, draw
The first spring 8 is stretched, the first sliding sleeve 5 play the guiding role, and the first slide bar 6, which moves up, drives brake block 9 to move up, at this time user
Perambulator can be moved, when user holds regulating wheel 22 and inverts, so that reel 23 be driven to invert, releases the second drawstring 19,
So that third slide bar 17 and third directional wheel 18 reset to the left, under the action of the first spring 8, the first slide bar 6 and brake block 9 to
Lower reset move perambulator can not to fix third wheel, so can in the case where not swinging hollow pipe 116,
So that perambulator is mobile or fixed.
Friction can be generated with friction plate 26 when user rotates regulating wheel 22, the 4th spring leaf 25 has buffer function, rubs
26 increasing friction force of wiping board so can prevent regulating wheel 22 in quilt so that regulating wheel 22 needs biggish power that can just be rotated
Toward revolution after rotation.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode can also be made without departing from the purpose of the present invention within the knowledge of those skilled in the art
Various change.
