[0020] Furthermore, the pressure plate is provided with an escape portion.

[0021] Furthermore, the positioning base plate is provided with a plurality of mounting through holes.

[0022] The beneficial effects of the utility model are:

[0023] (I) The installation method of the utility model is to fix the limit piece on the positioning base plate by bolts, place the workpiece in the workpiece placement through hole, then make the special end of the workpiece against the limit piece, and then fix the pressure plate on the positioning base plate by bolts and lock the bolts after positioning by positioning pins to make the pressure plate press the workpiece tightly.
