Runner is installed by shaft, what one end of shaft extended out to shell is externally connected to turning handle；The runner and lifting
Male screw connects；The lifting column sliding sleeve is on slide post, since runner is threadedly coupled with lifting column, so runner turns
Kinetic energy is enough to be risen or declines with lifting column.
Preferably, what the universal wheel rotated is sleeved in the deck of concave surface, the laterally homogeneous connection of surrounding of the universal wheel
There are four universal adjustment bars；Universal adjustment bar is for rotating universal wheel, to adjust the direction of grip slipper.
Preferably, the universal wheel is connected by magnet with grip slipper, and not only stability is preferable for such connection type,
And it removes also easily.
Preferably, the upper rack posts and lower fulcrum bar plug connection, under the effect of external force, upper rack posts can be in lower fulcrum bar
It moves up and down, to adjust the height of top plate.
Preferably, rubber pad is connected at the downside center of the top plate, it can be by sample after rubber pad and sample contacts
Upper surface flatten, convenient for the later stage test use.
A kind of sample testing universal fixture in irregular shape, is not only simple in structure, dismounts and safeguard in the utility model
Easy maintenance, and easy to operate, can be used for that complex-shaped, sectional dimension is small, the end of surface irregularity, the irregular sample of shape
Face is levelling, is particularly suitable for all kinds of samples and carries out hardness test.
