For convenience of description, the lower link pin 83 of the lower steering base 8 located in the left turning notch 63L is defined as a left lower link pin 83L, and the lower link pin 83 of the lower steering base 8 located in the right turning notch 63R is defined as a right lower link pin 83R.

As shown in fig. 13, when the user needs to turn, the operating handle 4 is directly dialed to the left, and then the first control bracket 5 is twisted to the left with respect to the second control bracket 6, and then the left front wheel 91L and the right front wheel 91R of the scooter are synchronously tilted to the left.

Meanwhile, the lower left connecting pin 83L slides rightward in the left turning notch 63L until it touches the rightmost end 63LM of the left turning notch 63L, whereupon the lower left connecting pin 83L stops sliding and continues to press the rightmost end 63 LM. At the same time, the lower right connecting pin 83R touches the guide block 64 in the right turning notch 63R and presses the guide block 64 to continue sliding rightward. In this process, the left and

right turning notches

63L and 63R of the second control bracket 6 are subjected to asymmetrical twisting force, so that the second control bracket 6 starts to turn leftward with respect to the operating handle 4, and the first control bracket 5 also turns leftward in synchronization with the second control bracket 6, as shown in fig. 14.

That is to say, when the user stirred operating handle 4 to the left, the left front wheel 91L and the right front wheel 91R of scooter when inclining to the left in step, first control support 5 and second control support 6 also rotated to the left in step, have reduced the required turning radius of scooter greatly, turn to also more steadily.

It should be noted that, by changing the position of the adjusting nut 65, the effective stroke of the guide block 64 can be adjusted, so as to control the rotating amplitude of the first control bracket 5 and the second control bracket 6, and the toy is suitable for children of different ages to play. For example, for younger children, the magnitude of the rotation of the first and

second control brackets

5 and 6 may be reduced.

As shown in fig. 15 to 21, a scooter 1A according to a second embodiment of the present invention is provided.

Unlike the first embodiment, a rectangular bushing 67A is provided inside the second control bracket 6A, and a bushing hole 671A is provided at each of four corners of the bushing 67A. A guide lining plate 10A is arranged on the lining frame 67A, a pair of inclined guide notches 101A which are symmetrically arranged is arranged on the guide lining plate 10A, lining plate fixing holes 102A are respectively arranged on four corners of the guide lining plate 10A, and the lining plate fixing holes 102A are matched with the lining frame holes 671A through screws.

A lever hole 411A is provided in the bottom of the control lever of the operating handle 4A, and a driving screw 43A is provided in the lever hole 411A, and the driving screw 43A is engaged with the guide notch 101A, which will be described further below.

The operation of this embodiment will be explained below.

When the user needs to turn, the operating handle 4A is directly dialed to the left, and then the first control bracket 5A is twisted to the left with respect to the second control bracket 6A, and then the left front wheel 91L and the right front wheel 91R of the scooter are synchronously tilted to the left, like the state shown in fig. 13.

At the same time, the drive screw 43A slides rightward along the guide slot 101A on the right side until the drive screw 43A abuts against the rightmost end of the guide slot 101A. During the sliding of the driving screw 43A, the second control bracket 6A is subjected to an asymmetric torsion force, so that the second control bracket 6A starts to rotate leftward with respect to the operating handle 4A, and the first control bracket 5A also rotates leftward in synchronization with the second control bracket 6A, similarly to the state shown in fig. 14.

It should be noted that the user can replace the guide liner with a different guide slot, such as the guide liner 10B shown in fig. 22, in which case the two guide slots 101B of the guide liner 10B are arc-shaped. Obviously, the length and shape of the guide slot of the guide lining plate determine the amplitude and speed of synchronous rotation of the first control bracket and the second control bracket. Alternatively, the drive screw 43A may be a spring pin, such that the drive screw 43A has a tendency to retract into the rod bore 411A no matter where the drive screw 43A slides.

Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
