It should and be connected and fixed by connecting shaft.
The structural schematic diagram of connecting shaft refers to Fig. 7, as shown in fig. 7, being that a kind of circular symmetry provided in this embodiment is cut
The connecting shaft on side, the shapes and sizes of the connecting shaft and the first through hole in Fig. 5 and Fig. 6 and the second through-hole it is identical, convenient for
When assembly, connecting shaft is passed through and is fixed in first through hole and the second through-hole, while can also be played using symmetrical trimming circle
Fixed effect connects the upper top surface of shaft under when connecting shaft is slided in the first strip through-hole and second bar through hole
Bottom surface and the side of the first strip through-hole and the second bar shaped contact with each other and support, and avoid the first connection component and the second connection component
Between rotate.
First connection component and the second connection component are cut by one piece of complete steel disc, if or being rushed by dry plate stalloy
It is pressed into.If the cost of manufacture that can reduce connection component is made of dry plate steel disc punching press, can also be incited somebody to action in stamped
Intermediate steel disc is substituted for the component of other materials, or intermediate space is filled by the way of injection molding, to reduce connection group

Property, improve the reliability of shaft.
In the present embodiment, when shaft is in the fully extended state, the fixing buckle of the latter connection component needs complete
It fastens to play position-limiting action in the notch of previous connection component, therefore, the shape of the first fixing buckle and the first notch
Shape it is identical, and the height of the first fixing buckle protrusion be equal to the first notch depth；The shape of second fixing buckle and second
The shape of notch is identical, and the height of the second fixing buckle protrusion is equal to the depth of the second notch.
In the present embodiment in order to reach good limit effect, at the same also when in order to cooperate the rotation of shaft, first is solid
Fixed button, the first strip through-hole and the first notch have certain radian, and the bending direction of radian is identical as the direction that shaft rotates,
The size of radian is related to the number of preceding latter linked first connection component and the second connection component, and number is more, and radian is smaller,
Number is fewer, and radian is bigger.Second fixing buckle, second bar through hole and the second notch have certain radian, the bending of radian
Direction is identical as the direction that shaft rotates, the number of the size of radian and preceding latter linked first connection component and the second connection component
Mesh is related, and number is more, and radian is smaller, and number is fewer, and radian is bigger.We illustrate so that shaft rotates 180 ° as an example, shaft
It is made of several first connection components and the second connection component, shaft needs uniformly to distribute to 180 ° into first in shaft
Connection component and the second connection component, therefore, the number of current latter linked first connection component and the second connection component are more
When, the radian of each first connection component and the distribution of the second connection component is also just smaller.
The problem of concurrently there are radian also and there is arc length, it is known that shaft is in the course of rotation, shaft it is interior
It is poor that there are arc length side and outside, and the arc length of inside is less than the arc length in outside, during rotation, outside due to the radius of gyration
Arc length be always greater than inside arc length, therefore, the first strip through-hole and the first fixing buckle of the first connection component, Yi Ji
The second bar through hole of two connection components and the arc length of the second fixing buckle are related with their position, example the present embodiment Fig. 5 and Fig. 6
The first connection component and the second connection component for, since the first strip through-hole of the first connection component and the first fixing buckle are set
It sets in front end close to intermediate position, and the second bar through hole of the second connection component and the setting of the second fixing buckle are close in front end
Position on the inside of shaft, therefore the arc length of the first strip through-hole and the first fixing buckle is greater than second bar through hole and second and fixes
The arc length of button, but their radian is identical.
In the present embodiment, since connecting shaft needs to slide back and forth in the first strip through-hole and second bar through hole, and
And first strip through-hole be connected and fixed by connecting shaft with the second through-hole, passing through with first through hole for second bar through hole is connect
Axis connection is fixed, therefore the width of the first strip through-hole is slightly larger than the width of the second through-hole, and the width of second bar through hole is bigger
In the width of first through hole.
