Wherein, carry out the guide effect through recess and two guard plate cooperations to the rack, the rethread guard plate is spacing to the rack, prevents rack bending deformation when using.

Preferably, the inner sides of the two L-shaped fixing frames are provided with guide rails, and the pressing block is provided with a sliding block which is matched with the guide rails and can be detachably fixed. Wherein, the cooperation through guide rail and slider is to the briquetting effect of leading, further prevents rack bending deformation when using, influences the tight effect of clamp.

Preferably, the upper end of the pressing block is provided with a convex part extending upwards, and the convex part is detachably fixed with the left rack and the right rack through bolts respectively. The convex part and the rack are detachably fixed through the bolt, so that the pressing block can be conveniently replaced according to the requirement of a workpiece, and the clamping and fixing are carried out.

The utility model has the advantages that two workpieces with different sizes or workpieces with height difference on the clamping surface can be quickly positioned and clamped; the guide rail and the sliding block are matched to guide the pressing block, so that the rack is prevented from bending and deforming when in use, and the clamping effect is prevented from being influenced; can also carry out the guide effect through recess and two guard plate cooperations to the rack, the rethread guard plate is spacing to the rack, prevents rack bending deformation when using.
