The distance between the movable clamping plate body 313 and the L-shaped clamping seat body 303 can be adjusted by rotating the two sets of adjusting screw components 32 through the screwed adjusting inner screw hole 314. In this way, it can be flexibly and conveniently adapted to clamping and limiting workpieces of different thicknesses and specifications.
