Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in figs. 1-7, a kind of sine wave teaching aid according to the utility model embodiment, including pedestal 1, the bottom
Spaced two sidewalls 2 are provided on seat 1, axis horizontal and with the two rotation connection is provided between two side walls 2
3, one end of the axis 3, which runs through the corresponding side wall 2 and is fixedly connected sequentially, pivoted arm 4 and handle 5, on the axis 3
Several annulus 6 are fixedly connected with, axial direction arrangement and several annulus 6 of several annulus 6 along the axis 3 are along described
The circumferential direction of axis 3 is arranged, and the top of two side walls 2 is fixedly connected with fixing seat 7, and the fixing seat 7 is in the vertical direction
Several columns 8 are slidably connected, several columns 8 are corresponded with several annulus 6, and the bottom of the column 8
It is supported on the annulus 6 being disposed below.
In a specific embodiment of the utility model, the handle 5 includes the inner shaft being fixedly connected with the pivoted arm 4
And it is set in the casing outside the inner shaft.
In a specific embodiment of the utility model, the inside of the annulus 6 is provided with retainer plate 9, the fixation
