[0052] The support block 32 is provided with a guide hole 321, in which a slider 322 is slidably arranged;

[0053] The slider 322 is fixed to the support plate 33 and the shift bar 331 on one side close to the filter press plate 2; and is fixed to the mounting block 34 on the other side.

[0054] An electronic dynamometer 35 is provided on the support block 32 , and a force measuring spring 351 at the bottom of the electronic dynamometer 35 is connected to the mounting block 34 ;

[0055] in:
