By using above-mentioned technical proposal, the rotation of axle sleeve can be driven by pullling winding, and the rotation of axle sleeve drives clockwork spring bullet The rotation of spring is so that clockwork spring is tightened up, after the power for pullling winding disappears, because clockwork spring has pretightning force, clockwork spring bullet Spring can drive axle sleeve to rotate, thus again drive winding scrolling so that winding reset, the design of this structure, can into When year people needs the carrying child bicycle to go home, it is only necessary to pull out winding, by way of pulling winding and driving bicycle, incite somebody to action from Driving pulling is taken home, and this mode is relatively simple, and than relatively labor-saving.

Bearing, the axle are provided with the two ends coordinated as further improvement of the utility model, the axle sleeve with cross bar The lateral wall held on the inside of axle sleeve with being close to, and madial wall and the cross bar of the bearing are interference fitted.

By using above-mentioned technical proposal, axle sleeve two ends are fixed on cross bar by the setting of bearing, can make pulling During winding, axle sleeve being capable of stability of rotation.

As further improvement of the utility model, provided with the housing for surrounding axle sleeve, the housing on the outside of the axle sleeve Front end face be provided with the bar hole passed for winding.

By using above-mentioned technical proposal, axle sleeve is protected using the housing provided with bar hole, is not influenceing to pull On the premise of winding, the clockwork spring inside axle sleeve and axle sleeve is protected, prevents extraneous factor to axle sleeve and clockwork spring Spring causes damage.

As further improvement of the utility model, the winding is connected with end cap in the one end for stretching out bar hole, described Housing is provided with the round boss for surrounding bar hole, and the end cap coordinates with round boss screw thread to be fixed.

By using above-mentioned technical proposal, the end cap that can be arranged on housing is set in winding, setting for cap is held first Putting can facilitate people to firmly grasp winding, meanwhile, end cap and round boss are connected through a screw thread fixation, not only prevent winding and are rolled up It is difficult to take out into housing, and can prevents when children ride child's bicycle, the head of winding is understood whipping and had influence on The security that child cycles.

As further improvement of the utility model, the end cap is provided with reflector in one end away from round boss.

By using above-mentioned technical proposal, the setting of reflector can facilitate vehicle to find children certainly in the case of dark Driving, it is to avoid vehicle is bumped against on child's bicycle, causes to damage to cycling children.

As further improvement of the utility model, the lateral wall of the end cap is provided with rubber sleeve.

By using above-mentioned technical proposal, the design of rubber sleeve mainly facilitates people to be affectedly bashful end cap, not only increases hand and end Maximum static friction force between lid, and also add the feel of end cap.

As further improvement of the utility model, the housing outer layer covers have spongy layer.

By using above-mentioned technical proposal, children are during cycling, during emergency brake, and head may impinge upon housing On, the setting of spongy layer mainly prevents the injury that housing may be caused to children head in this case.
