Parallel bar group is connected, support block is provided with handle, and support block is connected with leading screw, and nut is provided with the outside of leading screw, and nut connection passes
Lever, drive link are connected with parallel bar group, and leading screw end sets handwheel.
The quantity of described L-shaped bar, parallel bar group and drive link is 2.
Described parallel bar group is two parallel bars that structure is identical and is parallel to each other.
Described leading screw is connected by bearing with support block.
The connected mode of described drive link and a wherein bar for nut, drive link and parallel bar group is be hinged.
Described parallel bar group and the connected mode of L-shaped bar, parallel bar group and support block are be hinged.
The beneficial effects of the utility model：The utility model uses sets parallel bar group between support block and L-shaped bar, protects
Card L-shaped bar does not rotate, and vertical state when ensureing the change in location of clamping plate is constant, increases contact area, prevents loose contact,
The position of support block and clamping plate is controlled by handle, while the rotation of rotation hand wheel drive screw mandrel, nut are reciprocal along leading screw outside
Motion, by drive link to parallel bar group, so as to drive the folding of clamping plate, to adapt to the test article of different size；The utility model
With the advantages of simple in construction, easy to use, contact area is big, and measurement is accurate, and operating efficiency is high.
