The present invention relates to a kind of spin-off ball demonstrator, it is characterised in that：The two cantilevered axle other ends for being arranged on the rotation mandrel connector both sides connection that rotary shaft top is fixed on the shaft device set the support shaft on base Nei are each provided with a flyball, a support shaft is respectively connected in the middle part of two cantilevered axles, the support shaft other end, which is arranged on the support mandrel connector both sides set in the bearing of support shaft upper end, to be rotated, handle on shaft device can move up and down in the groove of support shaft side, and the rotary shaft of shaft device can do movement in mandrel connector centre bore is supported.Present invention is mainly used for the structure and principle for showing spin-off ball demonstrator.
Description
Technical field
The present invention relates to a kind of spin-off ball demonstrator.
Background technology
According to present teaching needs, the spin-off ball demonstrator that can show its structure and principle is devised.
The content of the invention
The present invention illustrates a kind of spin-off ball demonstrator to solve the above problems to people.
The technical solution used in the present invention is：
A kind of spin-off ball demonstrator, it is characterised in that：It is arranged on the shaft device set the support shaft on base Nei and rotates
The two cantilevered axle other ends of the rotation mandrel connector both sides connection that axle top is fixed are each provided with a flyball, two cantilevered axles middle part
A respectively piece support shaft of connection, the support shaft other end is arranged on the support mandrel connector both sides that set in the bearing of support shaft upper end can be with
Rotate, the handle on shaft device can move up and down in the groove of support shaft side, and the rotary shaft of shaft device is supporting
Movement can be done in mandrel connector centre bore.
Cantilevered axle on described rotation mandrel connector, one end are set as screw thread and are connected with flyball, and one end is set as boss and led to
Crossing the screw fixed hole on boss makes to be screwed on rotation mandrel connector, and middle part is fixed provided with support between the ends
Groove simultaneously uses screw and support axis connection by screw fixed hole.
Described support shaft has been connected with rotary shaft with cantilevered axle by screw, support mandrel connector, rotation mandrel connector
Centered on can be up and down.
The advantages and positive effects of the present invention：
The spin-off ball demonstrator structure of the present invention is exquisite, good appearance；Rationally distributed, firmly, rotation is normal, and the pattern of rotation is beautiful
See, be fixed on handle in 90 ° with bearing block side shape on shaft device by promoting, support shaft and cantilevered axle can be changed
Orientation, so as to change the skyborne position of flyball by spin-off axle.
The related content of spin-off ball is provided with the curricula in modern times, spin-off ball demonstrator can allow student's expansion thinking to be thought
The space of elephant, the dull atmosphere of regulation study, mitigates learning pressure, improves the interest of study.

Embodiment
Referring to the drawings and spin-off ball demonstrator is described in detail embodiment.The present invention is same as the prior art
Part has used identical symbol.
The spin-off ball demonstrator dimensional structure diagram of Fig. 1 present invention.A kind of spin-off ball demonstrator of the present invention as shown in Figure 1,
It is characterized in that：It is arranged on the rotation axis connection that rotary shaft top is fixed on the shaft device set the support shaft on base Nei
The two cantilevered axle other ends of device both sides connection are each provided with a flyball, and a support shaft, support are respectively connected in the middle part of two cantilevered axles
The axle other end, which is arranged on the support mandrel connector both sides set in the bearing of support shaft upper end, to be rotated, the hand on shaft device
Handle can move up and down in the groove of support shaft side, and the rotary shaft of shaft device can move in mandrel connector centre bore is supported
It is dynamic.
The cantilevered axle on mandrel connector is rotated, one end is set as screw thread and is connected with flyball, and one end is set as boss and passes through boss
On screw fixed hole make to be screwed on rotation mandrel connector, middle part is provided with support fixing groove and led between the ends
Cross screw fixed hole and use screw and support axis connection.
Support shaft has been connected centered on rotary shaft with cantilevered axle by screw, support mandrel connector, rotation mandrel connector
Can be up and down.
In summary, the spin-off ball demonstrator structure exquisiteness of the present invention, good appearance；Rationally distributed, firmly, rotation is normal,
The pattern of rotation is attractive in appearance, by promoting the handle of fixed bearing block side on the rotary shaft, can change parallelogram, so as to
The skyborne position of flyball is changed by spin-off axle；Spin-off ball demonstrator can allow student to deploy the space of the thinking imagination, adjust and learn
Dull atmosphere is practised, mitigates learning pressure, improves the interest of study.
