The technical principle of this programme：Swingle is vertically arranged through balancing pole, when swingle drives in external input device
When rotating too fast, also drive balancing pole rotation, the first sliding block of the hollow inside of balancing pole due to being thrown toward end by centrifugal force,
Deformation is caused to squeeze the first spring, the rotary speed of balancing pole is faster, and centrifugal force is bigger, squeezes the deformation of the first spring
Bigger, the displacement for thereby resulting in the movement of the first sliding block is also bigger.Since the first sliding block is by rigidly restricting across balancing pole bottom
Slit is connected with the second sliding block, when the first sliding block is subjected to displacement due to centrifugal force, has tractive force to the second sliding block, overcomes and rub
The pulling force of cleaning block bottom second spring is that brake pad has the tendency that moving up.When the rotary speed of balancing pole becomes larger, from
Mental and physical efforts also become larger, and the first sliding block also constantly becomes larger to the tractive force of the second sliding block, and brake pad is driven to be in contact with swingle, and two
Occur to rub between person and produce frictional force, certain obstruction is caused to the rotation of swingle, thus to the speed of rotation into
Row limitation.
The technique effect of this programme：Brake pad is driven to move upwards by the centrifugal force of the first sliding block, make brake pad and rotation
Bull stick is in contact, and is occurred to rub between the two and is produced frictional force, certain obstruction is caused to the rotation of swingle, so as to
The speed of rotation is limited, solving the rotating device of the existing technology being connected on motor may be due to rotation
It is too fast and the problems such as damage of components and parts is caused to be thrown out of.
It advanced optimizes：The swingle is equipped with ring flange, convenient to connect with external input device by setting ring flange
Connect use.
