Light, adjust semi-girder, you can the raised bottom dead center position of the circular arc planar of briquetting is accurately carried in armrest
Vertical force applies at position, goes far towards the reliability of testing result, and easy to operate.
Used as preferred technical scheme, described semi-girder is adjustable length semi-girder, and the semi-girder is horizontally disposed with, described frame
Being connected with one end of semi-girder by rotating shaft makes semi-girder rotate in the horizontal plane, and cable retracting mechanism is arranged on the other end of semi-girder
Place.
Used as preferred technical scheme, described cable retracting mechanism includes motor and the capstan winch being connected with motor,
Apertured partition or hollow tube are provided with below described capstan winch, described hawser is located in apertured partition or hollow tube, pushed up
End is connected with capstan winch.
Operating personnel's through hole controlled motor controls the length of hawser, the setting of apertured partition or hollow tube so that hawser
The stability of its stored position, prevents hawser during folding and unfolding due to rocking the wild effect for causing, and improves load applying
Accuracy.
Compared with prior art, that there is load to apply high, the convenient operation of accurate, testing result reliability etc. is excellent for the present invention
Point.
