And the descent direction along pedestal 10, the limited block 50 be located at the top of elastomer 40, i.e. elastomer 40 be sandwiched in pressurizing block 20 with
Between limited block 50；
The pedestal 10 is provided with the latch mechanism for optionally allowing for or preventing 50 opposite base of limited block, 10 activity.
In the present embodiment, the limited block 50, elastomer 40, pressurizing block 20 and tested device 30 are along the decline side of pedestal 10
To being sequentially arranged.
The present embodiment is by arranging limited block 50 using the support as elastomer 40, while the position by adjustment limited block 50
Put to adapt to pressurizing block 20 and the elastomer 40 of different size (such as different size, Different Weight).
In the present embodiment, the weight size of the elastic acting force of elastomer 40 and pressurizing block 20 can be according to the to be measured of reality
The concrete condition of examination device 30 is chosen.
A kind of embodiment, the pedestal 10 have top 102, and the holding channel 101 is through the top 102 of pedestal in pedestal
Top 102 form one and be available for the open top 103 that tested device 30, pressurizing block 20, elastomer 40 and limited block 50 pass through.
The holding channel other end is extended to
Closing end in contact.That is, holding channel is not through the bottom of pedestal, bottom imperforation.
Another kind of embodiment, the pedestal 10 have top 102, and the holding channel 101 is through the top 102 of pedestal in base
