As improvement of the present utility model, one end that described leading screw deviates from described bearing is provided with handwheel.
By adopting technique scheme, it is more convenient that the setting of handwheel makes leading screw rotate.
As improvement of the present utility model, described bearing is provided with slotted eye for placing bearing towards the end face of leading screw, The inner ring of described leading screw and described bearing is fixed, and the outer ring of described bearing is fixedly connected with described bearing.
By adopting technique scheme, the setting of described bearing is played and only can be applied water to bearing when leading screw rotates Flat active force.
As improvement of the present utility model, described pressure head is arc, and its radian direction deviates from described pressure head towards described bottom The side of seat.
By adopting technique scheme, described pressure head is set to arc, makes pressure head when applying pressure to testing sample, Testing sample is made to be that point contacts so as to when carrying out bending test, Detection results are more preferably with pressure head.
As improvement of the present utility model, described side plate is fixedly connected with described base by bolt.
By adopting technique scheme, side plate is bolted with base, makes the convenient dismounting of side plate, when bearing is being subject to When power generation abrasion needs to change, by dismantling side plate, you can skid off bearing.
As improvement of the present utility model, the side wall of described base indicates scale.
By adopting technique scheme, the side wall of described base indicates scale, facilitates staff to check and record is treated The size of test sample product.
In sum, this utility model has the advantages that:The setting of side plate is played and is supported and dispose actuator Effect, can also limit bearing simultaneously, prevent bearing from skidding off base, due to can adjust the position of bearing by actuator, be to prop up Seat can sliding on base, you can adapt to various sizes of testing sample.
