Prevent 4 lower end of inserted link with collet chuck 5 be clamped assembling process in because be axially inserted into depth not enough due to cause to be clamped it is unreliable.
Relative to embodiment one, in connection member 200 provided in this embodiment, elastomer 6 and collet chuck 5 are made into fission
Structure can facilitate separate machined, so as to reduce manufacturing process difficulty and reduce manufacturing cost.
<embodiment three>
In the present embodiment, identical appended drawing reference is given in part identical with embodiment two, and omits identical text and say
It is bright.
As shown in figure 12, relative to embodiment two, connection member 300 provided in this embodiment also has such knot
Structure: elastomer 6 is the annular shape elastic washer made of plastic cement or rubber, and the minimum internal orifice dimension of elastomer 6 is greater than on inserted link 4
The maximum gauge of the second end, this can prevent 4 lower end of inserted link to be clamped in assembling process with collet chuck 5 because being axially inserted into depth
It is unreliable that degree not enough causes to be clamped.
Relative to embodiment two, connection member 300 provided in this embodiment is by using rubber or the bullet of plastic cement support
Property washer substitution metal spring made of elastomer, material cost can be lowered.
The technical principle that detailed description of the preferred embodimentsthe present invention has been described is combined above, but it should be recognized that these above-mentioned
Description is intended merely to explain the principle of the present invention, and cannot be construed to the specific limit to the scope of the present invention in any way
System.Based on the explanation herein, those skilled in the art can associate other of the invention tools not making the creative labor
Body embodiment or equivalent replacement, fall within protection scope of the present invention.
